DCT_matrixImputation

Matrix imputation in gene expression data using DCT based sparsity

Matlab codes for matrix imputation-

  1. DCT_Stage1.m - Code for imputing missing values using only Stage-1 i.e DCT based sparsity
  2. CTNNBI.m - Code for introducing missing values randomly and then imputing missing values using DCT sparsity in Stage-1 and Nuclear Norm minimization based denoising in Stage-2 and finally calculating NRMSE
  3. TV_DCTcode2.m - Code for introducing missing values randomly and then imputing missing values using DCT based sparsity in Stage-1 and TV denosing in Stage-2 and finally calculating NRMSE
  4. TV_DCTcode1.m - Code for imputing missing values in incomplete matrix using TV-DCT algorithm

%% NOTE: please install spgl solver and keep it in your path in matlab for this algorithm to work
