A fast learning algorithm for deep belief nets Original Abstract. The lower layers receive top-down, directed connections from the layer above. Training a RBM 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. This problem does not arise with P 0 because the training data do not depend on the parameters.

Training our deep network . How Deep Learning algorithm works? Abstract. 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. By Geoffrey E. Hinton and Simon Osindero. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We show how to use “complementary priors” to eliminate the explainingaway effects that make inference difficult in densely connected belief nets that have many hidden layers.

Notes: A fast learning algorithm for deep belief nets Jiaxin Shi Department of Computer Science Tsinghua University Beijing, 100084 ishijiaxin@126.com 1 Motivation: Solve explaining away The motivation of this paper is to solve the difficulties caused by explaining away in learning deep directed belief nets. Fast learning and prediction are both essential for practical usage of RBM-based machine learning techniques. A fast learning algorithm for deep belief nets . This is the abstract from Hinton et al 2006. Fast learning and prediction are both essential for practical usage of RBM-based machine learning techniques. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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. 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. Deep Belief Nets Stacked Restricted Boltzmann Machine (RBM) RBM Nice property: given one side, easy to sample the other. The idea of the algorithm is to construct multi-layer directed networks, one layer at a time. Tools. 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. The main contribution of this paper is a fast greedy algorithm that can learn weights for a deep belief network. This paper proposes Lean Contrastive Divergence (LCD), a modified Contrastive Diver-gence (CD) algorithm, to accelerate RBM learning and prediction without changing the results.
