LibADMM

Introduction

This toolbox solves many sparse, low-rank matrix and low-rank tensor optimization problems by using M-ADMM developed in our paper [1].

List of Problems

The table below gives the list of problems solved in our toolbox. See more details in the manual at https://canyilu.github.io/publications/2016-software-LibADMM.pdf.

Version History

• Version 1.0 was released on June, 2016.
• Version 1.1 was released on June, 2018. Some key differences are below:
  • Add a new model about low-rank tensor recovery from Gaussian measurements based on tensor nuclear norm and the corresponding function lrtr_Gaussian_tnn.m
  • Update several functions to improve the efficiency, including prox_tnn.m, tprod.m, tran.m, tubalrank.m, and nmodeproduct.m
  • Update the three example functions: example_sparse_models.m, example_low_rank_matrix_models.m, and example_low_rank_tensor_models.m
  • Remove the test on image data and some unnecessary functions
