OverviewAlthough the CNN deep convolution network in the field of image recognition has achieved significant results, but so far people to why CNN can achieve such a good effect is unable to explain, and can not put forward an effective network promotion strategy. Using the method of Deconvolution visualization in this paper, the author discovers some problems of alexnet, and makes some improvements on the

isThe output at t time is not only dependent on the memory of the past, but also on what will happen later. Deep (bidirectional) Recurrent Neural Network Deep recurrent neural networks are similar to bidirectional recurrent neural networks,There are multiple layers in each duration. Deep cyclic

example, X1 is the Vow (Vector-of-word) vector of the second word in the current input sentence, PS: Using a computer to process natural languages requires that natural language processing be a symbol that can be recognized by the machine, plus that it needs to be numerically computed during machine learning. Word is the basis of natural language understanding and processing, so it needs to be numerically, word vector (word representation,word embeding) [1] is a feasible and effective method. W
