A multi-view graph convolutional network framework based on adaptive adjacency matrix and multi-strategy fusion mechanism for identifying spatial domains.

ABSTRACT:

Motivation

Spatial transcriptomics (ST) addresses the loss of spatial context in single-cell RNA-sequencing by simultaneously capturing gene expression and spatial location information. A critical task of ST is the identification of spatial domains. However, challenges such as high noise levels and data sparsity make the identification process more difficult.

Results

To tackle these challenges, STMGAMF, a multi-view graph convolutional network model that employs an adaptive adjacency matrix and a multi-strategy fusion mechanism is proposed. STMGAMF dynamically adjusts the edge weights to capture complex spatial structures during training by implementing the adaptive adjacency matrix and optimizes the embedded features through the multi-strategy fusion mechanism. STMGAMF is e
