Three different ways of initializing deep neural network yield surprising results

While training deep neural net, there are many parameters to be initialized and trained through the forward and backward propagation. A lot of times we spent a lot of time on trying different activation function, tuning the depth of deepnet, and number of units and other hyperparameters. 263 more words
