$rm K$-SVD: An Algorithm for Designing Overcomplete Dictionaries for Sparse Representation

Michal Aharon; Michael Elad; Alfred M. Bruckstein⋆ · IEEE Transactions on Signal Processing · 2006

In recent years there has been a growing interest in the study of sparse representation of signals. Using an overcomplete dictionary that contains prototype signal-atoms, signals are described by sparse linear combinatio...

A Fast Learning Algorithm for Deep Belief Nets

Geoffrey E. Hinton; Simon Osindero; Yee‐Whye Teh · Neural Computation · 2006

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...
