Introduction to deep learning - initial value of weight (Xavier,He initial value, distribution of activation function value of hidden layer)

Initial value of weight (the pit here is too deep. This article is just an introduction to in-depth learning and will not pursue theory in detail) In the learning of neural network, the initial value of weight is particularly important. In fact, what kind of weight initial value is set is often related to the success of neural network lea ...
