Monosemantic representations
- Single SAE dimensions correlate with counts of single cell types. For example, SAE-1736 represents plasma cell abundance exclusively
- The findings generalized to:
✅ Out-of-domain datasets (CPTAC)
✅ Different stains (H&E, IHC)
✅ Various scanners

🔍 Interpretable concepts found using SAE
- SAE trained on PLUTO embeddings disentangled polysemantic features. Single dimensions captured distinct concepts:
✅ Cell types (e.g., cancer cells, red blood cells)
✅Geometric features (e.g. edge of tissue)
✅ Artifacts (surgical ink)
