About Attribute Cell Network Model leverages identification of spatial domains from spatial transcriptomics data

Learning Topological Structure and Compatible Features of Cell Networks for Spatial Domains with Graph Denoising

Contributing authors: xkma@xidian.edu.cn;

stACN is an attribute cell network model to characterize and identify spatial domains in spatial transcriptomics data by integrating gene expression and spatial location information of cells. To fully exploit spatial and expression information of ST data, stACN simultaneously performs graph denoising and learns compatible features of cells for expression and spatial information by fully exploiting topological structure of attribute cell network with tensor decomposition. Then, stACN automatically learns cell affinity graph by manipulating the learned compatible features of cells with self- representation learning for spatial domain identification. Different from available approaches, stACN jointly integrates all these procedures such that noise and features of cells are modeled under the guidance of spatial domains, thereby improving performance of algorithms. Extensive experiments on various ST data from different platforms and tissues demonstrate the superiority of stANC on spatial domain detection, providing an effective and efficient model for analyzing ST data.
