, because the optimization function 12λw2 the derivation by not creating a constant item factor 2, but simply λw such a simple form. The intuitive interpretation of L2 regularization is that L2 regularization is a strong punishment for the spike vectors and tends to scatter the weight vectors. The other form of the 6.3 maximum norm constraint normalization is to enforce the absolute upper limit size in each neuron's weight vector, using the projection gradient descent to force the constraint. In

C ++ convolutional neural network example: tiny_cnn code explanation (10) -- layer_base and layer Class Structure Analysis In the previous blog posts, we have analyzed most of the layer structure classes. In this blog post, we plan to address the last two layers, it is also the two basic classes layer_base and layer that are at the bottom of the hierarchy for a b
