Understanding the Learned Iterative Soft Thresholding Algorithm with matrix factorization

2 Jun 2017 Thomas Moreau Joan Bruna

Sparse coding is a core building block in many data analysis and machine learning pipelines. Typically it is solved by relying on generic optimization techniques, such as the Iterative Soft Thresholding Algorithm and its accelerated version (ISTA, FISTA)... (read more)
