Granger causality network inference
WebJun 8, 2024 · We present a new framework for learning Granger causality networks for multivariate categorical time series, based on the mixture transition distribution (MTD) model. Traditionally, MTD is plagued by a nonconvex objective, non-identifiability, and presence of many local optima. To circumvent these problems, we recast inference in … Webby prior pseudotime-based GRN inference methods. We introduce our Single-cell Inference of Networks using Granger Ensembles (SINGE) algorithm, an ensemble-based GRN …
