To enhance the identification of cell types from single-cell RNA sequencing data through a new clustering framework.
Introduced scSCCNIA for effective cell clustering and marker gene identification
Utilized a Laplacian filter for neighbor information aggregation
Employed Siamese encoders for data augmentation and graph view construction
Applied similarity-matrix-based contrastive learning for low-dimensional embedding
scSCCNIA significantly outperformed existing clustering methods across multiple scRNA-seq datasets
Accurate identification of cell clusters and marker genes established
Revealed heterogeneity and functional specificity of cell types using enrichment analyses
