神经网络剖析激活函数优缺点（Undetanding the difficulty of training deep feedforward neural networks）

摘要：在2006年以前，似乎深度多层的神经网络没有被成功训练过。自那以后少数几种算法显示成功地训练了它们，实验结果表明了深度多层的架构的优越性。所有这些实验结果都是通过新的初始化或训练机制获得的。我们的目标是更好地理解为什么随机初始化的标准梯度下降法在深度神经网络下表现如此糟糕，为了更好地理解最近的相对成功并帮助设计未来更好的算法。我们首先观察了非线性激活函数的影响。我们发现logisticsig

【Deep Learning】笔记：Understanding the difficulty of training deep feedforward neural networks

这几天读了这篇论文，在这里将大致内容写在这里。Abstract介绍这篇论文的主要内容就是尝试更好的理解为什么使用“标准随机初始化”来计算使用标准梯度下降的网络效果通常来讲都不是很好。首先研究了不同的非线性激活函数的影响，发现sigmoid函数它的均值会导致在隐层中很容易到达函数的饱和区域，因此sigmoid激活函数在随机初始化的深度网络中并不合适。但同时惊喜的发现，处于饱和的神经元能够自己“逃脱出
