Convolutional cylinder-type block-circulant cycle codes [PDF]

Transactions on Combinatorics, 2013
In this paper, we consider a class of column-weight two quasi-cyclic low-density paritycheck codes in which the girth can be large enough, as an arbitrary multiple of 8. Then we devote a convolutional form to these codes, such that their generator matrix

Fast Convolutional Sparse Coding [PDF]

2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013
Sparse coding has become an increasingly popular method in learning and vision for a variety of classification, reconstruction and coding tasks. The canonical approach intrinsically assumes independence between observations during learning. For many natural signals however, sparse coding is applied to sub-elements ( i.e.
