-Specifically, the GoogleNet contains numerous inception modules, which are connected together to go deeper.  In general, an inception module with dimensionality reduction consists of **1×1 conv**, **3×3 conv**, **5×5 conv**, and **3×3 max pooling**, which are done altogether for the previous input, and stack together again at output.

In our model architecture, the kernel size used in inception module is 3×3 instead of 5×5.
