WebQuestion: Learning a new representation for examples (hidden layer activations) is always harder than learning the linear classifier operating on that representation. In neural networks, the representation is learned together with the end classifier using stochastic gradient descent. We initialize the output layer weights as W = W2 = 1 and Wo = -1. WebThe middle layer of nodes is called the hidden layer, because its values are not observed in the training set. We also say that our example neural network has 3 input units (not counting the bias unit), 3 hidden units, and 1 output unit. We will let n_l denote the number of layers in our network; thus n_l=3 in our example. destiny 2 how to get rose
