有关神经网络以及训练过程的基础知识。Basic concepts of neural network , and focus more on how the training process. ======

neural network

intro

although we get inspiration from neural network in biology , besides this , we can still have some insights. \(neural \;network:\;s=W_2 max(0,W_1x)\) \(linear \;classification:\;s=Wx\)

one neuron

the neuron get some input ,then through a activation function , output
