deep neural networks are highly expressive models that have recently achieved
state of the art performance on speech and visual recognition tasks. While
their expressiveness is the reason they succeed, it also causes them to learn
uninterpretable solutions that could have counter-intui
研究深度神经网络的学习动态，主要关注于二元分类问题。我们证明了网络学习的各种性质，并且在非线性架构下，分类误差也呈现出 sigmoid 形状，证实了经验观察。我们指出了梯度饱和现象和特征频率对模型收敛速度的影响，并探讨了交叉熵和 hinge 损失对生成对抗网络训练的差异。最后，我们提出了梯度饥饿现象并进行了研究。
