(a) Introduction to neural networksThe main use of computer computing power, a large number of samples to fit, and finally get a result we want, the result is 0-1 code, so OK(ii) Artificial neural network model I. Three basic elements of the basic

Weight attenuation is a common method to fit the problem.\ (l_2\)Norm RegularizationIn deep learning, we often use the L2 norm regularization, which is to add L2 norm penalty on the basis of the original loss function of the model, so as to get the

A recurrent neural network (RNN) is a class of neural networks that includes weighted connections within a layer (compared With traditional Feed-forward networks, where connects feeds only to subsequent layers). Because Rnns include loops, they can

BP (backward propogation) neural networkSimple to understand, neural network is a high-end fitting technology. There are a lot of tutorials, but in fact, I think it is enough to look at Stanford's relevant learning materials, and there are better

Solution of gradient vanishing/gradient explosion Firstly, the fundamental reason of gradient vanishing and gradient explosion is the inverse propagation algorithm based on BPAnd the above reverse propagation error is less than 1/4 In general, when
