Types of Deep Learning algorithms; What is Deep Learning? We show how to use "complementary priors" to eliminate the explaining-away effects that make inference difficult in densely connected belief nets that have many hidden layers. Fast learning and prediction are both essential for practical usage of RBM-based machine learning techniques. Deep belief nets have two important computational properties. Tools. ... albertbup/deep-belief-network. Fast learning and prediction are both essential for practical usage of RBM-based machine learning techniques. Deep Belief Nets Stacked Restricted Boltzmann Machine (RBM) RBM Nice property: given one side, easy to sample the other. A Fast Learning Algorithm for Deep Belief Nets Hinton, Osindero, Teh . The idea of the algorithm is to construct multi-layer directed networks, one layer at a time. Using complementary priors, we derive a fast, greedy algorithm that can learn deep, directed belief networks one layer at a time, provided the top two layers form an undirected associative memory. As each new layer is added, the overall generative model improves. A Fast Learning Algorithm for Deep Belief Nets 1535 is important to notice that Pnθ depends on the current model parameters, and the way in which Pnθ changes as the parameters change is being ig- nored by contrastive divergence learning.
