深度学习: GoogleNet 网络
Introduce
提出了 Inception_v1，开启了伟大的Inception系列，并刷新了网络的深度新记录。
这是一种 类似于 网中网（Network In Network）的结构，即原来的结点也是一个网络。
Paper：Going Deeper with Convolutions
Structure
伟大的Inception系列从那之后一直在不断发展，目前已经V2、V3、V4了。现今浪潮之巅的ResNeXt便是集ResNet与Inception大成者。
Inception的结构如下图所示：
其中1*1卷积主要用来降维，用了Inception之后整个网络结构的宽度和深度都可扩大，能够带来2-3倍的性能提升。
