O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book.

I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training.

图8-10 GoogLeNet（引用自文献[23]）
只看图的话，这似乎是一个看上去非常复杂的网络结构，但实际上它基
本上和之前介绍的
CNN
结构相同。不过，
GoogLeNet
的特征是，网络不仅
在纵向上有深度，在横向上也有深度（广度）。
GoogLeNet
在横向上有“宽度”，这称为“
Inception
结构”，以图 8

示的结构为基础。
如图8

11 所示，
Inception
结构使用了多个大小不同的滤波器（和池化），
最后再合并它们的结果。
GoogLeNet
的特征就是将这个
Inception
结构用作
一个构件（构成元素）。此外，在
GoogLeNet
中，很多地方都使用了大小为
