In this work, we propose layer-wise weight decay for efficient training of deep neural networks. Our method sets different values of the weight-decay coefficients layer by layer so that the ratio between the scale of back-propagated gradients and that of weight decay is constant through the network. Meer weergeven In deep learning, a stochastic gradient descent method (SGD) based on back-propagation is often used to train a neural network. In SGD, connection weights in the network … Meer weergeven In this section, we show that drop-out does not affect the layer-wise weight decay in Eq. (15). Since it is obvious that drop-out does not affect the scale of the weight decay, we focus instead on the scale of the gradient, … Meer weergeven In this subsection, we directly calculate \lambda _l in Eq.
