- To enhance the analysis of Spatially Resolved Transcriptomics data.
Main Methods:
- AdPrST utilizes pre-clustering for initial domain identification.
- Dual-view graph structures (KNN and r-radius) are constructed.
- Adversarial self-supervised contrast with Wasserstein GANs and contrastive learning generates embeddings.
- Embeddings are fused using dot-product attention for domain identification.
Main Results:
