Z. Shaeiri; M. R. Karami; A. Aghagolzadeh

Volume 8, Issue 1 , Winter 2020, , Pages 13-23

Abstract
  Sufficient number of linear and noisy measurements for exact and approximate sparsity pattern/support set recovery in the high dimensional setting is derived. Although this problem as been addressed in the recent literature, there is still considerable gaps between those results and the exact limits ...  Read More

M. Nikpour; R. Karami; R. Ghaderi

Volume 5, Issue 2 , Summer 2017, , Pages 223-234

Abstract
  Sparse coding is an unsupervised method which learns a set of over-complete bases to represent data such as image and video. Sparse coding has increasing attraction for image classification applications in recent years. But in the cases where we have some similar images from different classes, such as ...  Read More
