A two-layer sparse coding model learns simple and complex cell receptive fields and topography from natural images
Independent component analysis Natural images Neural networks Spatial vision
2015/8/10
The classical receptive fields of simple cells in the visual cortex have been shown to emerge from the statistical properties of natural images by forcing the cell responses to be maximally sparse, i....
Sparse coding for multitask and transfer learning
Sparse coding multitask transfer learning
2012/11/23
We present an extension of sparse coding to the problems of multitask and transfer learning. The central assumption of the method is that the tasks parameters are well approximated by sparse linear co...
Robust and Discriminative Image Authentication Based on Sparse Coding

2013/7/24
Image authentication is usually approached by checking the preservation of some invariant features, which are expected to be both robust and discriminative so that contentpreserving operations are acc...
