WebSep 6, 2024 · In this work, we presented a novel method to utilize weighted graph regularized matrix factorization (WGRMF) for inferring anticancer drug response in cell lines. We constructed a p-nearest neighbor graph to sparsify drug similarity matrix and cell line similarity matrix, respectively. Using the sparsified matrices in the graph … WebDetecting genomes with similar expression patterns using clustering techniques plays an important role in gene expression data analysis.
