Non-negative Matrix Factorization (NMF) is widely used as a data dimensionality reduction tool. However, the assumption of most conventional NMF-based methods is that the gene expression data are only destroyed by Gaussian noise. In practice, the gene expression data are unavoidably destroyed by sparse noise. Although Sparsity-Regularized Robust NMF by using L1/2 constraint (L1/2-RNMF) can achieve...
Salt restriction, the method which was acknowledged by modern medical knowledge that could delay kidney disease progression, was advanced in ancient times. We found that salt restriction therapies were presented in many ancient literatures during our ancient literature mining work. We sorted out the ancient trace of salt restriction about edema in chronic kidney disease (CKD). From frequency of herbals,...
