学习笔记:AlexNet&Imagenet学习笔记

ImageNet(http://www.image-net.org)是李菲菲组的图像库,和WordNet 可以结合使用 (毕业于Caltech;导师:Pietro Perona;主页:http://vision.stanford.edu/~feifeili/) 总共有十万的synset, 其中2010的数据表示,有图像的非空synset是21841,每一类大约1000张图片,图片总数:14197122。

Caffe中训练ImageNet使用的是Alex Krizhevsky的方法(AlexNet),这个有60million参数的模型(简称为AlexNet),在ILSVRC 2012中赢得了第一名,Top5错误率15.3%。

2013年,Clarifai通过cnn模型可视化技术调整网络架构,赢得了ILSVRC (http://www.clarifai.com/     看八卦 可以看zhihu.com   Filestorm:的一段闲聊: http://zhuanlan.zhihu.com/cvprnet/19821292)。

2014年,google也加入进来,它通过增加模型的层数(总共22层),并且利用multi-scale data training,取得第一名,Top5错误率 6.66%。Google的模型大大增加的网络的深度,并且去掉了最顶层的全连接层:因为全连接层(Fully Connected)几乎占据了CNN大概90%的参数,但是同时又可能带来过拟合(overfitting)的效果。它的模型比以前AlexNet的模型大大缩小,并且减轻了过拟合带来的副作用。Alex模型参数是60M,GoogLeNet只有7M。

 

2015年,百度用Deep Image,Top5错误率达到5.98% ,它基于GPU,利用36个服务节点开发了一个专为深度学习运算的supercompter(名叫Minwa,敏娲)。这台supercomputer具备TB级的host memory,超强的数据交换能力,训练了一个有100billion参数的巨大的深层神经网络。 (这一系统包含 36 个服务器节点,每一服务器节点配备了 2 颗六核英特尔至强 E5-2620 处理器。每个服务器包含 4 颗英伟达 Tesla K40m GPU,以及 1 个 FDR InfiniBand(速度为 56GB/S)。这带来了高性能、低延时的连接,以及对 RDMA 的支持。每一颗 GPU 的最高浮点运算性能为每秒 4.29 万亿次浮点运算,而每一颗 GPU 也配备了 12GB 的内存。整体来看,Minwa 内置了 6.9TB 的主内存、1.7TB 的设备内存,而理论上的最高性能约为 0.6 千万亿次浮点运算。凭借如此强大的系统,研究人员可以使用与其他深度学习项目不同,或者说更好的训练数据。因此,百度没有使用常见的 256x256 像素图片,而是使用了 512x512 像素图片,并且可以给这些图片添加各种特效,例如色彩调整、增加光晕,以及透镜扭曲等。这样做的目的是使系统学习更多尺寸更小的对象,并在各种环境下识别 对象。)

AlexNet整个模型比起之前我们看到的Cifar10 和LeNet模型相对来说复杂一些, 训练时间是在两台GTX 580 3GB GPUs上进行了5-6天的训练,其中用到了Hinton的改进方法(在全连接层加入ReLU+Dropout), 对于这个模型,我们首先认定一个完整的卷积层可能包括一层convolution,一层Rectified Linear Units,一层max-pooling,一层normalization。则整个网络结构包括五层卷积层和三层全连接层,网络的最前端是输入图片的原始像素点,最后端是图片的分类结果。

对于每一层网络,具体的网络参数配置如下图所示。InputLayer就是输入图片层,每个输入图片都将被缩放成227*227大小,分rgb三个颜色维度输入。Layer1~ Layer5是卷积层,以Layer1为例,卷积滤波器的大小是11*11,卷积步幅为4,本层共有96个卷积滤波器,本层的输出则是96个55*55大小的图片。在Layer1,卷积滤波后,还接有ReLUs操作和max-pooling操作。Layer6~ Layer8是全连接层,相当于在五层卷积层的基础上再加上一个三层的全连接神经网络分类器。以Layer6为例,本层的神经元个数为4096个。Layer8的神经元个数为1000个,相当于训练目标的1000个图片类别。

流程是一致的,不过对于每个值的计算过程 有点不一样。

然后我调用训练好的模型

MODEL_FILE = '../models/bvlc_reference_caffenet/deploy.prototxt'
PRETRAINED = '../models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel'

获取到预测结果,然后再标签里查找到对应的分类

imagenet_label = caffe_root + 'data/ilsvrc12/synset_words.txt'

输入一张猫的图片

输出前五个分类

['n02123045 tabby, tabby cat' 'n02127052 lynx, catamount'
 'n02124075 Egyptian cat' 'n07930864 cup' 'n02123159 tiger cat']
