Solutions

Using Kaggle cat and dog classification code,
even using there depth deeping networks ResNet50,Inception V3,
Xception to extract image features,
and using neural networkf DNN classification,
verification set shows over-fitting.

比赛思路

Direct image classificaton,select a network to extract features,followed by a fully connection layer classification,plus regularization to reduce over-fitting.Then let go of all levels of training.The final accuracy is about 0.92,in fact,as long as the default parameters do not depart from the spectrum on the line,adjusting the parameters does not have much impact on the results.
