Abstract

Reconstruction of gene regulatory networks (GRNs) is essential for uncovering regulatory relationships between transcription factors (TFs) and target genes. With advances in single-cell RNA sequencing (scRNA-seq), cell-type-specific GRN inference has become an important direction in systems biology; however, existing deep learning methods still struggle with noisy expression, symmetric link scoring that cannot capture regulatory direction, and difficulty separating co-expression and co-regulation from direct regulation. Built upon the variational autoencoder (VAE)-graph attention network (GAT) framework of GRANet [1], we propose DMVD-GRN with enhanced VAE multi-view denoising, skew-symmetric directed decoding, and structure-aware joint decoding, integrating expression correlation, second-order adjacency, and Jaccard co-regulation priors. On 14 tasks of the STRING benchmark, DMVD-GRN achieves superior AUROC and AUPRC, with more pronounced AUPRC gains, thereby improving identification of true regulatory edges under extreme class imbalance.
