Webof greedy layer-wise pre-training to initialize the weights of an entire network in an unsupervised manner, followed by a supervised back-propagation step. The inclusion of the unsupervised pre-training step appeared to be the missing ingredient which then lead to significant improvements over the conventional training schemes. Web• Training: Q(h2 h1 ) W 2 – Variational bound justifies greedy 1 1 W layerwise training of RBMs Q(h v) Trained by the second layer RBM 21 Outline • Deep learning • In usual settings, we can use only labeled data – Almost all data is unlabeled! – The brain can learn from unlabeled data 10 Deep Network Training (that actually works)
Webtraining process, which led researchers to exploit a pre-training phase that allowed them to initialize network weights in a region near a good local optimum [4, 5]. In these studies, greedy layerwise pre-training was per-formed by applying unsupervised autoencoder models layer by layer, thus training each layer to provide a WebIn the old days of deep learning, pracitioners ran into many problems - vanishing gradients, exploding gradients, a non-abundance of compute resources, and so forth. In addition, …
