题目: 1)In the first step, apply the Convolution Neural Network method to perform the training on one single CPU and testing 2)In the second step, try the distributed training on at least two CPU/GPUs and evaluate the training time. 一.单机单卡实现mnist_CNN 1
损失函数,一般由两项组成,一项是loss term,另外一项是regularization term. J=L+R 先说损失项loss,再说regularization项. 1. 分对得分1,分错得分0.gold standard 2. hinge loss(for softmargin svm),J=1/2||w||^2 + sum(max(0,1-yf(w,x))) 3. log los, cross entropy loss function in logistic regression
