Cross-modal errors span across multiple modaltities, like mismatched images or incorrect text fields, and are are an overlooked but critical issue in domains like e-Commerce and healthcare. Even with modern tools, large orgs struggle to catch cross-modal errors.

📊 Key findings:
- Specialized single-cell frameworks and scFMs excel at uni-modal batch correction
- Generic SSL methods like VICReg & SimCLR outperform on cell typing & multi-modal tasks
- Masking emerges as the most universally effective augmentation strategy

Furthermore, we find that masking leads to the biggest performance improvement for creating augmented views of a cell.

Our bechmark shows that SimCLR and VICReg are the best methods for single-cell data across batch integration, query-to-reference, and missing modality prediction tasks.
