mobile communications and machine learning are two of the most exciting and rapidly developing technological fields of our time. In the past few years, these two fields have begun to merge in two fundamental ways. First, while mobile communications has developed largely as a model-driven field, the complexities of many emerging communication scenarios raise the need to introduce data-driven methods into the design and analysis of mobile networks. Second, many machine learning problems are by their nature distributed due to either physical limitations or privacy concerns. This distributed nature can be exploited by using mobile networks as part of the learning mechanisms, i.e., as platforms for machine learning.
移动通信和机器学习是当今最令人兴奋和发展最快的两个技术领域。在过去的几年里，这两个领域已经开始以两种基本的方式融合。首先，虽然移动通信在很大程度上已经发展成为一个模型驱动的领域，但许多新兴通信场景的复杂性使得需要在移动网络的设计和分析中引入数据驱动方法。其次，许多机器学习问题由于物理限制或隐私问题的性质而分布。利用移动网络作为学习机制的一部分，即作为机器学习的平台，可以利用这种分布式性质。
In this tutorial we will illuminate these two perspectives, presenting a representative set of relevant problems which have been addressed in the recent literature, and discussing the multitude of exciting research directions which arise from the combination of machine learning and wireless communications. We will begin with the application of machine learning methods for optimizing wireless networks: Here, we will first survey some of the challenges in communication networks which can be treated using machine learning tools. Then, we will focus on one of the fundamental problems in digital communications – receiver design. We will review different designs of data driven receivers, and discuss how they can be related to conventional and emerging approaches for combining machine learning and model-based algorithms. We will conclude this part of the tutorial with a set of communication-related problems which can be tackled in a data-driven manner.
在本教程中，我们将阐述这两个观点，介绍一组在最近的文献中已经解决的具有代表性的相关问题，并讨论由机器学习和无线通信相结合而产生的众多令人兴奋的研究方向。我们将从应用机器学习方法优化无线网络开始：在这里，我们将首先调查通信网络中的一些挑战，这些挑战可以使用机器学习工具来处理。然后，我们将集中讨论数字通信中的一个基本问题——接收机设计。我们将回顾数据驱动接收器的不同设计，并讨论它们如何与用于结合机器学习和基于模型的算法的传统和新兴方法相关。我们将以一组与通信相关的问题结束本教程的这一部分，这些问题可以用数据驱动的方式解决。
The second part of the tutorial will be dedicated to wireless networks as a platform for machine learning: We will discuss communication issues arising in distributed learning problems such as federated learning and collaborative learning. We will explain how established communications and coding methods can contribute to the development of these emerging distributed learning technologies, illustrating these ideas through examples from recent research in the field. We will conclude with a set of open machine learning related problems, which we believe can be tackled using established communications and signal processing techniques.
本教程的第二部分将专门介绍作为机器学习平台的无线网络：我们将讨论分布式学习问题中出现的通信问题，如联合学习和协作学习。我们将解释已建立的通信和编码方法如何有助于这些新兴的分布式学习技术的发展，并通过该领域最新研究的实例说明这些想法。最后，我们将提出一系列与开放式机器学习相关的问题，我们相信这些问题可以通过现有的通信和信号处理技术来解决。

eep neural networks have recently demonstrated their incredible ability to solve complex tasks. Today’s models are trained on Millions of examples using powerful GPU cards and are able to reliably annotate images, translate text, understand spoken language or play strategic games such as chess or go. Furthermore, deep learning will also be integral part of many future technologies, e.g., autonomous driving, Internet of Things (IoT) or 5G networks. Especially with the advent of IoT, the number of intelligent devices has rapidly grown in the last couple of years. Many of these devices are equipped with sensors that allow them to collect and process data at unprecedented scales. This opens unique opportunities for deep learning methods.
eep神经网络最近已经证明了它们解决复杂任务的不可思议的能力。今天的模型使用强大的GPU卡在数百万个例子上进行训练，能够可靠地注释图像、翻译文本、理解口语或玩象棋或围棋等战略游戏。此外，深度学习也将是许多未来技术的组成部分，例如，自主驾驶、物联网（IoT）或5G网络。特别是随着物联网的出现，智能设备的数量在过去几年里迅速增长。这些设备中的许多都配备了传感器，使它们能够以前所未有的规模收集和处理数据。这为深入学习方法提供了独特的机会。
However, these new applications come with several additional constraints and requirements, which limit the out-of-the-box use of current models.
然而，这些新的应用程序附带了一些额外的约束和要求，这些约束和要求限制了当前模型的开箱即用。
Embedded devices, IoT gadgets and smartphones have limited memory & storage capacities and restricted energy resources. Deep neural networks such as VGG-16 require over 500 MB for storing the parameters and up to 15 giga-operations for performing a single forward pass. Such models in their current (uncompressed) form cannot be used on-device.
嵌入式设备、物联网设备和智能手机的内存和存储容量有限，能源资源有限。VGG-16这样的深层神经网络需要500兆以上的内存来存储参数，执行一次前向传递需要高达15千兆的操作。这些当前（未压缩）形式的模型不能在设备上使用。
Training data is often distributed over devices and cannot simply be collected at a central server due to privacy issues or limited resources (bandwidth). Since a local training of the model with only few data points is often not promising, new collaborative training schemes are needed to bring the power of deep learning to these distributed applications.
训练数据通常分布在设备上，由于隐私问题或资源（带宽）有限，不能简单地在中央服务器上收集。由于只有很少数据点的模型的局部训练往往是不可能的，因此需要新的协作训练方案来为这些分布式应用带来深度学习的能力。
This tutorial will discuss recently proposed techniques to tackle these two problems.
本教程将讨论最近提出的解决这两个问题的技术。

although processing and analyzing audio, images and video is still of great importance in current society, more and more data is originating from networks with an irregular structure, e.g., social networks, brain networks, sensor networks, and communications networks to name a few. To handle such signals, graph signal processing has recently been coined as a proper tool set. In graph signal processing the irregular structure of the network is captured by means of a graph, and the data is viewed as a signal on top of this graph, i.e., a graph signal. Graph signal processing extends concepts and tools from classical signal processing to the field of graph signals, e.g., the Fourier transform, filtering, sampling, stationarity, etc. Since nowadays many researchers and engineers work in the field of network data processing, this tutorial is attractive, timely and critical. Further, most existing tutorials in this field focus on the basics of graph signal processing. Hence, it is urgent to go one step beyond and discuss the latest advances in graph signal processing as well as connections to the exciting fields of distributed optimization and neural networks, both of which draw inspiration from fundamental signal processing techniques.
尽管音频、图像和视频的处理和分析在当今社会仍然具有重要的意义，但越来越多的数据来自于结构不规则的网络，例如社交网络、大脑网络、传感器网络和通信网络等等。为了处理这些信号，图形信号处理最近被创造成一个合适的工具集。在图形信号处理中，网络的不规则结构是通过一个图形来捕获的，数据被看作是这个图形上的一个信号，即一个图形信号。图形信号处理将概念和工具从经典的信号处理扩展到图形信号领域，如傅立叶变换、滤波、采样、平稳性等。由于目前许多研究人员和工程师在网络数据处理领域工作，本教程具有吸引力、及时性和批判性。此外，这一领域的大多数现有教程都侧重于图形信号处理的基础知识。因此，迫切需要超越和讨论图形信号处理的最新进展，以及与分布式优化和神经网络这两个激动人心的领域的联系，这两个领域都从基本的信号处理技术中得到启发。
More specifically, in this tutorial, we will emphasize the concept of graph filtering, one of the cornerstones of the field of graph signal processing. Graph filters are direct analogues of time-domain filters but intended for signals defined on graphs. They find applications in image denoising, network data interpolation, signal and link prediction, learning of graph signals and building recommender systems. More recently, connections to distributed optimization as well as neural networks have been established. These last two applications rely heavily on core signal processing techniques such as iterative inversion algorithms and linear time-invariant filters. Graph filters extend these concepts to graphs, leading to key developments in distributed optimization and neural networks.
更具体地说，在本教程中，我们将强调图形滤波的概念，图形信号处理领域的基石之一。图滤波器是时域滤波器的直接类似物，但用于图上定义的信号。它们在图像去噪、网络数据插值、信号和链路预测、图形信号学习和建立推荐系统等方面有着广泛的应用。最近，分布式优化和神经网络已经建立了联系。最后两个应用严重依赖于核心信号处理技术，如迭代反演算法和线性时不变滤波器。图过滤器将这些概念扩展到图，导致了分布式优化和神经网络的关键发展。

the cultural heritage sector is experiencing a digital revolution driven by the growing adoption of non-invasive, non-destructive spectroscopic imaging approaches generating multi-dimensional data from entire artworks. Such approaches include ‘macro X-ray fluorescence’ (MA-XRF) scanning or hyper-spectral imaging (HSI) in the visible and infrared ranges and are highly complementary to more traditional broad band digital imaging techniques such as X-ray radiography (XRR) or infrared reflectography (IRR).
文化遗产部门正在经历一场数字革命，其驱动力是越来越多地采用非侵入性、非破坏性的光谱成像方法，从整个艺术品中生成多维数据。这些方法包括可见光和红外范围内的“宏观X射线荧光”（MA-XRF）扫描或高光谱成像（HSI），与更传统的宽带数字成像技术（如X射线照相术（XRR）或红外反射成像（IRR）高度互补。
This data –spanning both the spatial and spectral domains– holds information about both materials at the surface of an artwork but also about sub-surface layers or features of interest otherwise invisible to the naked eye. The ability to interrogate the wealth of data yielded by these techniques can potentially provide insights into an artist’s materials, techniques and creative process; reveal the changing condition of an artwork over time and its restoration history; help inform strategies for the conservation and preservation of artworks; and, importantly, offer means by which to present artwork to the public in new ways.
这些数据横跨空间域和光谱域，包含了艺术品表面两种材料的信息，也包含了亚表面层或肉眼看不见的感兴趣特征的信息。对这些技术所产生的大量数据进行查询的能力，可以潜在地洞察艺术家的材料、技术和创作过程；揭示艺术作品随时间变化的状况及其修复历史；有助于为保护和保存艺术作品的策略提供信息；而且，重要的是，以新的方式向公众展示艺术品的方式。
However, to do this successfully also calls for new sophisticated signal and image processing tools capable of addressing various challenges associated with the analysis, interrogation, and processing of such massive multi-dimensional datasets. These challenges derive from the fact that paintings are very complex objects where
然而，要成功地做到这一点，还需要新的复杂的信号和图像处理工具，能够应对与分析、查询和处理这种大规模多维数据集相关的各种挑战。这些挑战源于绘画是非常复杂的物体
Materials are often present in intimate mixtures applied over multi-layered systems so signals deriving from spectroscopic imaging techniques are highly nonlinearly mixed.
材料通常以多层系统上的紧密混合物存在，因此光谱成像技术产生的信号是高度非线性混合的。
Materials also age/degrade over time so signals collected from spectroscopic imaging techniques cannot be often compared to signals present in reference libraries.
材料也会随着时间老化/降解，因此从光谱成像技术收集的信号不能经常与参考库中的信号进行比较。
A ‘ground-truth’ is often unavailable or limited because each painting is unique, with original materials often unknown, and materials’ aging process also unknown.
因为每幅作品都是独一无二的，原材料往往是未知的，材料的老化过程也未知，所以一个“基本真相”往往是不可能或有限的。
In addition, different spectroscopic imaging techniques reveal different details about artwork, so there is also a need to develop new signal and image processing tools combining different datasets in order to understand artwork.
此外，不同的光谱成像技术揭示了艺术品的不同细节，因此还需要开发结合不同数据集的新的信号和图像处理工具来理解艺术品。
This tutorial –which is offered by experts in applied mathematics, signal & image processing, machine learning, and heritage science– (a) reviews the state-of-the-art in signal and image processing for art investigation (b) reviews signal and image processing challenges arising in the examination of datasets acquired on artwork and © overviews emerging directions in signal processing for art investigation.
本教程-由应用数学、信号与图像处理、机器学习、计算机辅助教学、计算机辅助教学和计算机辅助教学等领域的专家提供，和遗产科学–（a）回顾艺术调查的信号和图像处理的最新技术（b）回顾检查艺术品上获得的数据集时出现的信号和图像处理挑战，以及（c）概述艺术调查信号处理的新方向。

moore’s law has indeed prevailed since he outlined his empirical rule-of-thumb in 1965, but based on this trend the scale of integration is set to depart from classical physics, entering nano-scale integration, where the postulates of quantum physics have to be obeyed. The quest for quantum-domain communication and processing solutions was inspired by Feynman’s revolutionary idea in 1985: particles such as photons or electrons might be relied upon for encoding, processing and delivering information. Hence in the light of these trends it is extremely timely to build an interdisciplinary momentum in the area of quantum signal processing and communications, where there is an abundance of open problems for a broad community to solve collaboratively. In this workshop-style interactive presentation we will address the following issues:
摩尔定律自1965年概述其经验经验经验法则以来，确实盛行，但基于这一趋势，积分的尺度设置偏离经典物理，进入纳米级积分，在那里必须遵守量子物理的假设。对量子域通信和处理解决方案的探索灵感来自费曼1985年的革命性想法：光子或电子等粒子可能被用来编码、处理和传递信息。因此，鉴于这些趋势，在量子信号处理和通信领域建立一种跨学科的势头是非常及时的，在这一领域，有大量的开放问题需要广大社区共同解决。在本次研讨会式互动演示中，我们将讨论以下问题：
We commence by highlighting the nature of the quantum channel, followed by techniques of mitigating the effects of quantum decoherence using quantum codes.
我们首先强调量子信道的性质，然后是利用量子码来减轻量子退相干效应的技术。
Then we bridge the subject areas of large-scale search problems in wireless communications and exploit the benefits of quantum search algorithms in multi-user detection, in joint-channel estimation and data detection, localization and in routing problems of networking, for example.
然后，我们将无线通信中大规模搜索问题的主题领域联系起来，并利用量子搜索算法在多用户检测、联合信道估计和数据检测、定位和网络路由问题等方面的优势。

with rapid developments in signal processing and data analytics, driven by technological advances towards a more intelligent networked world, there is an ever-increasing need for reliable and robust information extraction and processing. Robust statistical methods account for the fact that the postulated models for the data are fulfilled only approximately and not exactly. In contrast to classical parametric procedures, robust methods are not significantly affected by small changes in the data, such as outliers or minor model departures. In practice, many engineering applications involve measurements that are not Gaussian and that may contain corrupted measurements and outliers, which cause the data distributions to be heavy-tailed. This leads to a breakdown in performance of traditional signal processing techniques that are based on Gaussian models.
随着信号处理和数据分析技术的迅速发展，在技术进步的推动下，向更智能的网络世界发展，对可靠和可靠的信息提取和处理的需求日益增加。稳健的统计方法解释了这样一个事实：数据的假设模型只得到了近似的实现，而不是精确的实现。与经典的参数化方法相比，稳健方法不受数据的微小变化（如离群值或微小模型偏离）的显著影响。在实际应用中，许多工程应用涉及非高斯的测量，这些测量可能包含损坏的测量和异常值，从而导致数据分布是重尾的。这导致基于高斯模型的传统信号处理技术的性能崩溃。
The focus of this tutorial is on recent advances in the related areas of robust detection and robust cluster analysis for unsupervised learning. This tutorial is organized into two parts. In the first part, we discuss robust detection for a given number of hypotheses. In the second part, we move to robust cluster analysis with a focus on recent advances in robust cluster enumeration.
本教程的重点是无监督学习的鲁棒检测和鲁棒聚类分析相关领域的最新进展。本教程分为两部分。在第一部分中，我们讨论了给定假设数下的鲁棒检测。在第二部分中，我们将讨论稳健聚类分析，重点是稳健聚类枚举的最新进展。

Sony Workshop: AI x Audio: From Research to Production

AI x Audio: From Research to Production
AI x音频：从研究到生产
AI has changed the way we process and create audio, especially music. This opens new possibilities and enables new products that could not be envisioned some years ago. In this industry session, we want to give an overview of Sony’s activities in this field.
人工智能改变了我们处理和创造音频的方式，特别是音乐。这开辟了新的可能性，并使一些年前无法预见的新产品成为可能。在本次行业会议上，我们想概述一下索尼在这一领域的活动。
We start this session with an introduction into music source separation. Sony has been active in AI-based source separation since 2013 and our systems have repeatedly won international evaluation campaigns. In the last years, we could successfully integrate this technology into a number of products, which we will introduce as well.
我们从介绍音乐源分离开始这节课。索尼自2013年以来一直积极开展基于人工智能的源代码分离，我们的系统多次赢得国际评估活动。在过去的几年里，我们可以将这项技术成功地集成到许多产品中，我们也将引进这些产品。
Recently, INRIA released -in collaboration with Sony- open-unmix, an open-source implementation of our music source separation. open-unmix is available for NNabla as well as PyTorch.
最近，INRIA与索尼合作发布了一个开源的音乐源代码分离实现。NNabla和Pythorch都有开放的联尼特派团。
Finally, in this first part, we will briefly introduce the NNabla open-source project. NNabla is Sony’s Deep Learning Library, which we are actively developing worldwide. We will give a brief overview of its main features and compare it to other popular DL frameworks. We will highlight its focus on network compression and speed, making it a good choice for audio and music product development and prototyping.
最后，在第一部分中，我们将简要介绍NNabla开源项目。NNabla是索尼的深度学习图书馆，我们正在全球范围内积极开发。我们将简要概述它的主要特性，并将其与其他流行的DL框架进行比较。我们将重点关注网络压缩和速度，使之成为音频和音乐产品开发和原型制作的良好选择。
In the second part of the session, we will present our activities on music creation where we envision technologies that could drive music for the years to come. Through deep learning-based approaches, we develop tools that enhance a composer’s creativity and augment his capabilities. In our talk, we briefly present our research activities, including details about the underlying machine learning models. For these tools to be relevant, we rely on close collaboration with artists from Sony Music Entertainment, which can sometimes be tricky. Indeed, we are often experiencing a gap that exists between scientific research and the music industry on many levels, such as timeliness or profitability. Hence, the presentation will also address our efforts to bridge that gap.
在会议的第二部分，我们将介绍我们在音乐创作方面的活动，我们设想在未来几年里可以推动音乐发展的技术。通过基于深度学习的方法，我们开发了增强作曲家创造力和增强其能力的工具。在我们的演讲中，我们简要介绍了我们的研究活动，包括关于底层机器学习模型的细节。为了使这些工具具有相关性，我们依赖于与索尼音乐娱乐公司（Sony Music Entertainment）的艺术家们的密切合作，这有时是很棘手的。事实上，我们经常遇到科学研究和音乐产业在许多层面上的差距，例如及时性或盈利能力。因此，本报告还将讨论我们为弥合这一差距所作的努力。

Signal processing is at the core of the 5G communication technology. The use of large arrays with 64 or more antennas is becoming mainstream and the commercial deployment started in 2019. This technology is known as Massive MIMO (multiple-input multiple-output) and was viewed as science fiction just ten years ago, but with the combination of advanced signal processing and innovative protocols, it is now a reality. Just as the seminal papers on Massive MIMO were published ten years ago, this is likely the time when the new technology components for 6G will be identified. In this tutorial, we will consider two such promising research directions, which might be utilized in the conventional cellular spectrum as well as in mmWave or sub-THz bands.
信号处理是5G通信技术的核心。使用64个或更多天线的大型阵列正在成为主流，商业部署从2019年开始。这项技术被称为大规模MIMO（multiple input multiple output，多输入多输出），十年前还被视为科幻小说，但随着先进信号处理和创新协议的结合，现在已经成为现实。正如10年前发表的关于大规模MIMO的开创性论文一样，现在很可能是确定6G的新技术组件的时候。在本教程中，我们将考虑两个这样有前途的研究方向，它们可以用于传统的蜂窝频谱以及毫米波或亚太赫兹波段。
The first new direction is Cell-free Massive MIMO, which refers to a large-scale distributed antenna system that is made practical by innovative signal processing and radio resource allocation algorithms. Different from cellular communications, each user is served by all or a user-unique subset of the antennas. The system is designed to achieve high spectral and energy efficiency, but under the unusual constraint of being scalable from a computational and cost perspective to enable large network deployments. The main goal is to achieve uniformly good and reliable service via excessive macro-diversity, as compared to the micro-diversity achieved by conventional Massive MIMO with large arrays. We will cover the basic theory as well as the recent algorithmic and implementation developments.
第一个新的方向是无小区大规模MIMO，它是指通过创新的信号处理和无线资源分配算法使大规模分布式天线系统实用化。与蜂窝通信不同，每个用户由天线的全部或用户唯一子集服务。该系统旨在实现高频谱和能源效率，但在不寻常的限制下，可从计算和成本角度扩展，以实现大型网络部署。其主要目标是通过过多的宏分集来实现一致的良好和可靠的服务，与传统的大阵列大规模MIMO相比。我们将介绍基本理论以及最近的算法和实现发展。
The second new direction is intelligent reflecting surfaces, which are also known as software-controlled meta-surfaces and reconfigurable intelligent surfaces. These are semi-passive surfaces consisting of an array of meta-atoms with reconfigurable properties that can be controlled to reflect an incoming wave in a controllable way. While only the transmitter and receiver can be optimized in conventional wireless communication systems, the addition of intelligent reflecting surfaces enables optimization also of the channels (i.e., the creating of smart radio environments). We will derive the propagation model from physics and tackle difficult issues such as channel estimation and real-time operation.
第二个新方向是智能反射面，也称为软件控制的元曲面和可重构的智能曲面。这些是半被动表面，由具有可重构特性的元原子阵列组成，这些元原子阵列可以控制以可控方式反射入射波。虽然在传统无线通信系统中只能优化发射机和接收机，但增加智能反射面也可以优化信道（即创建智能无线电环境）。我们将从物理学中导出传播模型，并解决诸如信道估计和实时操作等难题。

Despite the fact of achieving high standard accuracy in a variety of machine learning tasks, deep learning models built upon neural networks have recently been identified having the issue of lacking adversarial robustness. The decision making of well-trained deep learning models can be easily falsified and manipulated, resulting in ever-increasing concerns in safety-critical and security-sensitive applications requiring certified robustness and guaranteed reliability.

This tutorial will provide an overview of recent advances in the research of adversarial robustness, featuring both comprehensive research topics and technical depth. We will cover three fundamental pillars in adversarial robustness: attack, defense and verification. Attack refers to efficient generation of adversarial examples for robustness assessment under different attack assumptions (e.g., white-box or black-box attacks). Defense refers to adversary detection and robust training algorithms to enhance model robustness. Verification refers to attack-agnostic metrics and certification algorithms for proper evaluation of adversarial robustness and standardization. For each pillar, we will emphasize the tight connection between signal processing and the research in adversarial robustness, ranging from fundamental techniques such as first-order and zero-order optimization, minimax optimization, geometric analysis, model compression, data filtering and quantization, subspace analysis, active sampling, frequency component analysis to specific applications such as computer vision, automatic speech recognition, natural language processing and data regression.

This tutorial aims to serve as a short lecture for researchers and students to access the emergent filed of adversarial robustness from the viewpoint of signal processing.

尽管在各种机器学习任务中都达到了很高的标准精度，但是最近发现基于神经网络的深度学习模型存在缺乏对抗性鲁棒性的问题。训练有素的深度学习模型的决策很容易被篡改和操纵，导致对安全性要求严格且对安全性要求很高的应用程序的担忧日益增加，这些应用程序需要经过认证的鲁棒性和保证的可靠性。

本教程将概述对抗性鲁棒性研究的最新进展，包括全面的研究主题和技术深度。我们将涵盖对抗性鲁棒性的三个基本支柱：攻击，防御和验证。攻击是指在不同攻击假设（例如白盒或黑盒攻击）下有效生成对抗性示例的鲁棒性评估。防御是指对手检测和鲁棒训练算法以增强模型的鲁棒性。验证是指与攻击无关的指标和认证算法，用于正确评估对抗性的鲁棒性和标准化。对于每个支柱，我们都将强调信号处理与对抗性鲁棒性研究之间的紧密联系，

本教程旨在作为短期讲座，供研究人员和学生从信号处理的角度访问新兴的对抗鲁棒性文件。

Neural Networks have achieved resounding success in a variety of learning tasks. Although sometimes overlooked, success has not been uniform across all learning problems and it has not been achieved by generic architectures. Most remarkable accomplishments are on the processing of signals in time and images and have been attained by Convolutional Neural Networks (CNNs). This is because convolutions successfully exploit the regular structure of Euclidean space and enable learning in high dimensional spaces.

In this tutorial we will develop the novel concept of Graph Neural Networks (GNNs), which intend to extend the success of CNNs to the processing of high dimensional signals in non-Euclidean domains. They do so by leveraging possibly irregular signal structures described by graphs. The following topics will be covered:

Graph Convolutions and GNN Architectures. The key concept enabling the definition of GNNs is the graph convolutional filter introduced in the graph signal processing (GSP) literature. GNN architectures compose graph filters with pointwise nonlinearities. Illustrative examples on authorship attribution and recommendation systems will be covered.
Fundamental Properties of GNNs. Graph filters and GNNs are suitable architectures to process signals on graphs because of their permutation equivariance. GNNs tend to work better than graph filters because they are Lipschitz stable to deformations of the graph that describes their structure. This is a property that regular graph filters can’t have.
Distributed Control of Multiagent Systems. An exciting application domain for GNNs is the distributed control of large scale multiagent systems. Applications to the control of robot swarms and wireless communication networks will be covered.
Attendees to this tutorial will be prepared to tackle research on the practice and theory of GNNs. Coding examples will be provided throughout.

神经网络在各种学习任务中都取得了巨大的成功。尽管有时会被忽略，但在所有学习问题中，成功并不一致，并且通用架构也未实现成功。卷积神经网络（CNN）是在时间和图像信号处理方面取得的最杰出成就。这是因为卷积成功地利用了欧几里得空间的规则结构，并允许在高维空间进行学习。

在本教程中，我们将开发图形神经网络（GNN）的新颖概念，其意图是将CNN的成功扩展到非欧氏域中高维信号的处理。它们通过利用图形描述的可能不规则的信号结构来做到这一点。将涵盖以下主题：

图卷积和GNN架构。定义GNN的关键概念是在图信号处理（GSP）文献中引入的图卷积滤波器。GNN架构构成具有逐点非线性的图形滤波器。本文将介绍作者身份归属和推荐系统的示例。
GNN的基本属性。图形滤波器和GNN由于其置换等方差，因此是处理图形信号的合适体系结构。GNN倾向于比图形过滤器更好地工作，因为它们对于描述其结构的图形的变形是Lipschitz稳定的。这是常规图形过滤器无法拥有的属性。
多主体系统的分布式控制。GNN的一个激动人心的应用领域是大规模多主体系统的分布式控制。将介绍控制机器人群和无线通信网络的应用程序。
本教程的参与者将准备进行有关GNN的实践和理论的研究。全文将提供编码示例。

Tutorial T-10: Biomedical Image Reconstruction—From Foundations to Deep Neural Networks

生物医学图像重建-从基础到深度神经网络
by
Michaël Unser and Pol del Aguila Pla
CIBM, EPFL

Biomedical imaging plays a key role in medicine and biology. Its range of applications and its impact in research and medical practice have increased steadily during the past 4 decades. Part of the astonishing improvements in image quality and resolution is due to the use of increasingly sophisticated signal-processing techniques. This, in itself, would justify the tutorial. Nonetheless, the field is now transitioning towards the deep-learning era, where disruptive improvements and lack of theoretical background go hand-in-hand. To harness the power of these new techniques without suffering from their pitfalls, a structured understanding of the field is fundamental.

We start the tutorial by presenting the building blocks of an image-reconstruction problem, from the underlying image that lives in function spaces to its observed discrete measurements. Most importantly, we detail the small collection of forward and sampling operators that allow one to model most biomedical imaging problems, including magnetic resonance imaging, bright-field microscopy, structured-illumination microscopy, x-ray computed tomography, and optical diffraction tomography. This leads up to our exposition of 1st-generation methods (e.g., filtered back-projection, Tikhonov regularization), the regimes in which they are most attractive, and how to implement them efficiently.

We then transition to 2nd-generation methods (non-quadratic regularization, sparsity, and compressive sensing) and show how advanced signal processing allows image reconstruction with smaller acquisition times, less invasive procedures, and lower radioactive and irradiation dosage. We expose the foundations of these methods (results in compressed-sensing recovery, representer theorems, infinite-divisible distributions) and the most useful algorithms in imaging (proximal operators, projected gradient descent, alternate-direction method of multipliers), again exemplifying their efficient implementation.

Finally, we present the state of the art in 3rd-generation methods (deep-learning reconstruction of images), categorizing them using the building-block terminology introduced throughout the tutorial. In this manner, we emphasize the links to 1st- and 2nd-generation methods in order to provide intuition and guidelines to devise and understand novel 3rd-generation methods. Furthermore, we state the benefits of each proposal and give cautionary examples of the dangers of overreliance on training data.

生物医学成像在医学和生物学中起着关键作用。在过去的40年中，其应用范围及其在研究和医学实践中的影响稳步增长。图像质量和分辨率的惊人提高的部分原因是由于使用了越来越复杂的信号处理技术。这本身就可以证明本教程的合理性。尽管如此，该领域现在正在过渡到深度学习时代，在那个时代，颠覆性的改进和缺乏理论背景齐头并进。为了利用这些新技术的力量而不遭受其陷阱，对这一领域的结构化理解至关重要。

我们通过介绍图像重建问题的构建块开始本教程，从生活在功能空间中的基础图像到观察到的离散测量值。最重要的是，我们详细介绍了少量的正向运算符和采样运算符，使他们可以对大多数生物医学成像问题进行建模，包括磁共振成像，明场显微镜，结构照明显微镜，X射线计算机断层扫描和光学衍射断层扫描。这导致我们对第一代方法（例如，滤波反投影，Tikhonov正则化）进行了阐述，介绍了它们最有吸引力的系统以及如何有效地实施它们。

然后，我们过渡到第二代方法（非二次正则化，稀疏性和压缩感测），并展示先进的信号处理如何以更少的采集时间，更少的侵入性程序以及更低的放射性和辐射剂量实现图像重建。我们介绍了这些方法的基础（压缩感知恢复的结果，表示定理，无限可分分布）和成像中最有用的算法（近距离算子，投影梯度下降，乘法器的交替方向方法），再次证明了它们的高效性实施。

最后，我们以第三代方法（图像的深度学习重建）展示了最新技术，并使用了整个教程中介绍的构建模块术语对它们进行分类。以这种方式，我们强调与第一代和第二代方法的联系，以提供设计和理解新颖的第三代方法的直觉和指导。此外，我们陈述了每个提案的好处，并给出了过度依赖培训数据的危险的警告示例。

Recent years have shown significant advances in many signal processing tasks based on machine learning techniques. Deep learning as well as reinforcement learning techniques have shown a tremendous value for classification, noise reduction and many other tasks. Recent advances in transferring the learning process to the edge of the network in order to protect the privacy of users’ data, as well as exploit the computational resources available at the mobile devices stimulated the development of techniques such as federated learning. In contrast, learning over networks of selfish agents is much less understood and holds the potential for the next leap in learning techniques. To allow distributed learning, both in the federated and distributed contexts, efficient communication techniques are required to save both energy and bandwidth. The tutorial will present recent results related to distributed learning under communication constraints. We will survey basic protocols which can be utilized to achieve efficient learning and then implement them to multiple examples of collaborative spectrum access as well as other resource sharing problems.

近年来，在基于机器学习技术的许多信号处理任务中显示出了显着的进步。深度学习以及强化学习技术已显示出对分类，降噪和许多其他任务的巨大价值。为了保护用户数据的私密性以及利用移动设备上可用的计算资源，将学习过程转移到网络边缘的最新进展刺激了诸如联合学习之类的技术的发展。相比之下，通过自私行为者网络进行学习的了解却很少，并且具有学习技术下一次飞跃的潜力。为了允许在联邦和分布式环境中进行分布式学习，需要有效的通信技术来节省能量和带宽。本教程将介绍与交流约束下的分布式学习相关的最新结果。我们将调查可用于实现有效学习的基本协议，然后将其应用于协作频谱访问以及其他资源共享问题的多个示例。

Extreme crowding of electromagnetic spectrum in recent years has led to the emergence of complex challenges in designing, sensing and communications systems. The advent of novel technologies –such as drone-based customer services, autonomous driving, radio-frequency identification, and weather monitoring– imply sensors like radars are now deployed in urban environments and operate in bands that were earlier reserved for communications services. Similarly, with rapid surge in mobile network operators, there is a growing concern that the amount of mobile data traffic poses a formidable challenge toward realizing future wireless networks. Both radar and communications systems need wide bandwidth to provide a designated quality-of-service thus resulting in competing interests in exploiting the spectrum. Hence, sharing spectral and hardware resources of communications and radar is imperative toward efficient spectrum utilization.

Specifically, in the automotive sector, state sensing and communication are two major tasks enabling future high-mobility applications such as Vehicular to Everything (V2X) where a node must continuously track its dynamically changing environment and react accordingly by exchanging information with others. This field has, therefore, witnessed concerted and intense efforts towards realizing these joint radar-communications (JRC) systems. Most of the modern automotive JRC systems are envisaged to operate at millimeter-wave (mm-Wave); this brings a new set of challenges and opportunities for the system engineers when compared with centimeter-wave (cm-Wave) JRC. This band is characterized by severe penetration losses, short coherence times, and availability of wide bandwidth. While wide bandwidth is useful in attaining high vehicular communications data rates and high-resolution automotive radar, the losses must be compensated by using large number of antennas at the transmitter and receiver. There is, therefore, a recent surge in research on joint multiple-input multiple-output (MIMO)-Radar-MIMO-Communications (MRMC) systems, where the antenna positions of radar and communications are shared with each other. Both systems may share information with each other to benefit from increased number of design degrees-of-freedom (DoFs).

This tutorial takes a focused view on mm-Wave JRC touching the entire spectrum of this field. After attending the tutorial, participants will be able to understand:

Current challenges and design criteria associated with mm-Wave JRC.
Information theoretic modeling and fundamental limits of joint sensing-communications.
Overview of communication and radar systems including waveform design and data/ target detection-estimation-tracking theoretic criteria, receiver processing algorithms for mm-Wave JRC.
Hardware design aspects of example JRC designs.
Emerging research challenges and solutions in MRMC

近年来，电磁频谱的极端拥挤导致在设计，传感和通信系统中出现了复杂的挑战。基于无人机的客户服务，自动驾驶，射频识别和天气监控等新技术的问世，意味着雷达等传感器现在已部署在城市环境中，并在为通信服务保留的频段中运行。类似地，随着移动网络运营商的迅速增长，人们越来越担心移动数据业务量将对实现未来的无线网络提出巨大的挑战。雷达和通信系统都需要宽带宽来提供指定的服务质量，因此在利用频谱方面引起了竞争。因此，

具体而言，在汽车领域，状态检测和通信是实现未来的高移动性应用（如车到万物（V2X））的两个主要任务，其中节点必须不断跟踪其动态变化的环境并通过与他人交换信息来做出相应的反应。因此，在这一领域见证了为实现这些联合雷达通信（JRC）系统而进行的一致而艰苦的努力。大多数现代汽车JRC系统被设想为在毫米波（mm-Wave）下运行。与厘米波（JCW）相比，这给系统工程师带来了一系列新的挑战和机遇。该频带的特点是严重的穿透损耗，较短的相干时间和宽带宽的可用性。虽然宽带宽可用于获得高的车载通信数据速率和高分辨率的汽车雷达，但必须通过在发射器和接收器处使用大量天线来补偿损耗。因此，最近对联合多输入多输出（MIMO）-雷达-MIMO-通信（MRMC）系统的研究激增，其中雷达和通信的天线位置彼此共享。两个系统可能会彼此共享信息，以受益于更多的设计自由度（DoF）。雷达和通讯的天线位置彼此共享。两个系统可能会彼此共享信息，以受益于更多的设计自由度（DoF）。雷达和通讯的天线位置彼此共享。两个系统可能会彼此共享信息，以受益于更多的设计自由度（DoF）。

Signal Processing Meets Deep Learning in MATLAB – From Getting Started to Developing Real-World Applications
The adoption of deep learning across a wide range of signal processing applications has been attracting an increasing level of attention over the last few years. Deep learning for real-world signal processing systems has accentuated the need for application-specific tools and expertise for creating, labelling, augmenting and processing the vast amounts of signal data required to train and evaluate the learning models.

Plenary Deep Representation Learning (Yoshua Bengio)

Tuesday, 5 May
10:00 - 11:00
Deep Representation Learning
Abstract: A crucial ingredient of deep learning is that of learning representations, more specifically with the objective to discover higher-level representations which capture and disentangle explanatory factors. This is a very ambitious goal and current state-of-the-art techniques still fall short, often capturing mostly superficial features of the data, which leaves them vulnerable to adversarial attacks and insufficient out-of-distribution robustness.This talk will review these original objectives, supervised and unsupervised approaches, and outline research ideas towards better representation learning.

ISS 1.3: Enabling Industrial IoT with 5G and Beyond

ISS 1.3：实现5G及以上工业物联网
5G is seen as a key enabler for achieving flexible implementation of industrial IoT (IIoT), where rigid wired connections can be replaced with low-latency and high-reliability wireless communications. Such flexible implementation paves the way for scalable operations, where the production can be more easily altered and scaled up, e.g., by adding new machines to the production cells of a production line. Nevertheless, the current industrial communications are supported by a diverse set of communication protocols addressing the associated application requirements. Moreover, new use cases, such as distributed machine controllers providing the needed flexibility, should be supported by the 5G system (5GS) design. In this talk, we will outline the key requirements for IIoT and the associated challenges for 5G Release 17 and beyond. We will further elaborate on the architectural framework for supporting distributed machine controllers.
5G被视为实现工业物联网（IIoT）灵活实施的关键促成因素，在工业物联网中，刚性有线连接可以被低延迟和高可靠性的无线通信所取代。这种灵活的实现为可扩展操作铺平了道路，在这种操作中，生产可以更容易地改变和扩展，例如，通过向生产线的生产单元添加新机器。然而，目前的工业通信由一组满足相关应用需求的不同通信协议支持。此外，5G系统（5GS）设计应支持新的用例，例如提供所需灵活性的分布式机器控制器。在本次演讲中，我们将概述IIoT的关键要求以及5G 17版及更高版本的相关挑战。我们将进一步阐述支持分布式机器控制器的体系结构框架。

ISS 3.1: Intelligent ear-level devices for hearing enhancement and health and wellness monitoring

ISS 3.1：用于听力增强和健康与健康监测的智能耳位装置
With resurgence of artificial intelligence (AI) and machine learning, sensor miniaturization and increased wireless connectivity, ear-level hearing devices are going through a major revolution transforming themselves from traditional hearing aids into modern hearing enhancement and health and wellness monitoring devices. For the aging user population of hearing aids, sound quality and speech understanding in challenging listening environments remain unsatisfactory. To improve quality of life and reduce health care cost, it is highly desirable if the devices can provide effective health and wellness monitoring capability on a continuous basis in everyday life. Finally, as the device functionality becomes more complex and dexterity is a major challenge for our user population, easy and intuitive user interactions with the devices are becoming increasingly important. In this talk, we will present examples of such transformation in the areas of hearing enhancement, health and wellness monitoring and user experience. In the process, we will highlight how AI and machine learning, miniaturized sensors and wireless connectivity are enabling and accelerating the transformation. In addition, we will discuss practical challenges for the transformation in areas of power consumption, non-volatile and volatile storage, audio latency and wireless reliability. Finally, we will provide an outlook on future directions and opportunities for intelligent ear-level devices.
随着人工智能（AI）和机器学习的兴起，传感器的小型化和无线连接的增强，耳廓听力设备正经历一场重大的革命，从传统的助听器向现代的听力增强和健康监测设备转变。随着助听器使用人口的老龄化，在充满挑战的听力环境中，其音质和语音理解能力仍不尽如人意。为了提高生活质量和降低医疗保健成本，如果这些设备能够在日常生活中持续提供有效的健康和健康监测能力，是非常理想的。最后，随着设备功能变得越来越复杂，灵巧性对我们的用户群来说是一个重大挑战，用户与设备的简单直观的交互变得越来越重要。在本次讲座中，我们将介绍在听力增强、健康和健康监测以及用户体验等领域的此类转变。在这个过程中，我们将强调人工智能和机器学习、微型传感器和无线连接是如何实现和加速这一转变的。此外，我们还将讨论在功耗、非易失性和易失性存储、音频延迟和无线可靠性方面的实际挑战。最后，我们将展望智能耳级设备的未来发展方向和机遇。

ISS 3.2: Digitization of Urban Sound in a Smart Nation

ISS 3.2：智能国家中城市声音的数字化
In this digital era, sensing and processing are being integrated into IoT devices that can be easily and economically deployed in our urban environment. In this talk, the speaker will describe some of the digital sound and active noise mitigation technologies that have been developed in my lab and some pilot deployment in our urban environment. In order to achieve a holistic understanding of our urban environment, we must rely on intelligent sound sensing that can operate 24/7 and deploy widely under different environmental conditions. These intelligent sound sensors also serve as digital ears to complement and activates the digital eyes of the CCTV cameras. By having a comprehensive and big aural sound data allows public agencies to better formulate complete and accurate sound mitigation policies. Sound pressure level (SPL) readings have been the de facto standard in quantifying our noise environment; however, SPL alone cannot accurately indicate how humans actually perceive noise; whether they like or dislike the sound even at the same SPL. The latest ISO standards (i.e. ISO 12913-1:2014, ISO 12913-2:2018) have been moving towards a measurement that is based on how humans perceive sound. With the advent of powerful and low-cost embedded processors, analog-to-digital convertors, and acoustic sensors, we are now seeing wide-spread usage of digital active noise control (ANC) technologies in consumer products, like hearables and in automobiles. In this talk, the speaker will also showcase our latest work in extending active noise control applications to a larger region of control, such as in open windows and openings of noise sources. Digitization plays a key role in advancing the art of ANC to incorporate artificial intelligence to select the most annoying noise to cancel and provide ways to further mitigate noise by perceptual-based sound augmentation.
在这个数字时代，传感和处理正被集成到物联网设备中，这些设备可以方便、经济地部署在我们的城市环境中。在本次演讲中，演讲者将介绍我的实验室开发的一些数字声音和主动降噪技术，以及在我们的城市环境中的一些试验性部署。为了全面了解我们的城市环境，我们必须依靠能够在不同环境条件下全天候运行和广泛部署的智能声音传感。这些智能声音传感器还充当数字耳朵，以补充和激活闭路电视摄像机的数字眼睛。通过拥有全面而庞大的声音数据，公共机构可以更好地制定完整而准确的声音缓解政策。声压级（SPL）读数已成为量化我们的噪声环境的事实标准；然而，单凭SPL无法准确地指出人类是如何实际感知噪声的；即使在相同的SPL下，他们是否喜欢或不喜欢声音。最新的ISO标准（即ISO 12913-1:2014、ISO 12913-2:2018）已经朝着基于人类感知声音的测量方向发展。随着功能强大、成本低廉的嵌入式处理器、模数转换器和声学传感器的出现，我们现在看到数字有源噪声控制（ANC）技术在消费品（如可听设备和汽车）中的广泛应用。在本次演讲中，演讲者还将展示我们在将有源噪声控制应用扩展到更大的控制区域方面的最新工作，例如在打开的窗口和噪声源的开口处。数字化在推进ANC技术中起着关键作用，它结合人工智能来选择最讨厌的噪声来抵消，并通过基于感知的声音增强提供进一步降低噪声的方法。

ISS 3.3: Mechanical Noise Suppression: Debutant of phase in signal enhancement after 30 years of silence

ISS 3.3：机械噪声抑制：沉默30年后的相位信号增强
This talk presents challenges, solutions, and applications in commercial products of mechanical noise suppression. The topic has become more important as dissemination of consumer products that process environmental signals in addition to human speech. Three typical types of mechanical noise signals with small, medium, and large signal power, represented by feature phones and camcorders, digital cameras, and standard and tablet PCs, respectively, are covered. Mechanical noise suppression for small power signals is performed by continuous spectral template subtraction with a noise template dictionary. Medium power mechanical noise is suppressed in a similar manner only when its presence is notified by the parent system such as the digital camera. When the power is large, explicit detection of the mechanical noise based on phase information determines suppression timings. In the all three scenarios, the phase information of the input noisy signal is randomized for making the residual noise inaudible in frequency bins where noise is dominant. The phase has been unaltered in the past 30 years after Lim, thus, these suppression algorithms opened the door to a new signal
本文介绍了机械噪声抑制在商业产品中的挑战、解决方案和应用。随着消费品的传播，这个话题变得越来越重要，这些消费品除了处理人类的语言外，还处理环境信号。介绍了三种典型的小、中、大信号功率机械噪声信号，分别以功能手机和摄像机、数码相机、标准和平板电脑为代表。采用带噪声模板字典的连续谱模板减法对小功率信号进行机械噪声抑制。只有当诸如数码相机的父系统通知其存在时，才以类似的方式抑制中等功率机械噪声。当功率较大时，基于相位信息的机械噪声的显式检测决定了抑制时序。在这三种情况下，输入噪声信号的相位信息是随机的，以使噪声占主导地位的频率箱中的残余噪声听不见。在Lim之后的30年里，相位没有改变，因此，这些抑制算法为新的信号打开了大门
