 GoogLeNet is a new neural network structure designed by Google in 2014, which, together with VGG network, became the twin champions of the ImageNet challenge that year. GoogLeNet introduces the Inception structure for the first time, and stacks the Inception structure in the network so that the number of network layers reaches 22, which is also the mark of the convolutional network exceeding 20 layers for the first time. Since 1x1 convolution is used in the Inception structure to reduce the dimension of channel number, and Global pooling is used to replace the traditional method of processing features in multiple fc layers, the final GoogLeNet network has much less FLOPS and parameters than VGG network, which has become a beautiful scenery of neural network design at that time.
 
+InceptionV3 is an improvement of InceptionV2 by Google. First of all, the author optimized the Inception module in InceptionV3. At the same time, more types of Inception modules were designed and used. Further, the larger square two-dimensional convolution kernel in some Inception modules in InceptionV3 was disassembled into two smaller asymmetric convolution kernels, which can greatly save the amount of parameters.
+
 Xception is another improvement to InceptionV3 that Google proposed after Inception. In Xception, the author used the depthwise separable convolution to replace the traditional convolution operation, which greatly saved the network FLOPS and the number of parameters, but improved the accuracy. In DeeplabV3+, the author further improved the Xception and increased the number of Xception layers, and designed the network of Xception65 and Xception71.
 
 InceptionV4 is a new neural network designed by Google in 2016, when residual structure were all the rage, but the authors believe that high performance can be achieved using only Inception structure. InceptionV4 uses more Inception structure to achieve even greater precision on Imagenet-1k.

 GoogLeNet是2014年由Google设计的一种新的神经网络结构，其与VGG网络并列成为当年ImageNet挑战赛的双雄。GoogLeNet首次引入Inception结构，在网络中堆叠该结构使得网络层数达到了22层，这也是卷积网络首次超过20层的标志。由于在Inception结构中使用了1x1的卷积用于通道数降维，并且使用了Global-pooling代替传统的多fc层加工特征的方式，最终的GoogLeNet网络的FLOPS和参数量远小于VGG网络，成为当时神经网络设计的一道亮丽风景线。
 
+InceptionV3是Google 对InceptionV2的一种改进。首先，InceptionV3 对 Inception模块进行了优化，同时设计和使用了更多种类的Inception模块，与此同时，InceptionV3中的部分Inception模块将较大的方形二维卷积拆成两个较小的非对称卷积，这样可以大幅度节省参数量。
+
 Xception 是 Google 继 Inception 后提出的对 InceptionV3 的另一种改进。在Xception中，作者使用了深度可分离卷积代替了传统的卷积操作，该操作大大节省了网络的FLOPS和参数量，但是精度反而有所提升。在DeeplabV3+中，作者将Xception做了进一步的改进，同时增加了Xception的层数，设计出了Xception65和Xception71的网络。
 
 InceptionV4是2016年由Google设计的新的神经网络，当时残差结构风靡一时，但是作者认为仅使用Inception 结构也可以达到很高的性能。InceptionV4使用了更多的Inception module，在ImageNet上的精度再创新高。
