For convenience, we have built an adjacency matrix Y ∈ R m×n to formalize the known miRNA-disease associations that acquired from the HMDD v2.0 database (Li et al., 2014).The known miRNA-disease associations dataset used in this paper includes 5430 distinct experimentally confirmed miRNA-disease between 383 … 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 …
WebThe contributions of this article is threefold. First, we propose a probabilistic explanation for graph-regularization methods and the learnable graph-regularization for the first time. This idea combines probabilistic matrix factorization (PMF) and graph-regularized matrix decomposition (GRMD) into a single effective probabilistic model. This ... WebIn this work, we propose a novel matrix completion framework that makes use of the side-information associated with drugs/diseases for the prediction of drug-disease indications modeled as neighborhood graph: Graph regularized 1-bit matrix completion (GR1BMC).
