DD 2.7: BBB Permeability Predictor
Fine-tuned ChemBERTa-77M-MLM on the BBBP dataset for binary classification of blood-brain barrier (BBB) permeability (permeable vs non-permeable).
Key Results (Scaffold Split Test Set, 13 Epochs)
- Accuracy: 84.48%
- F1 Score: 90.38%
- ROC-AUC: 0.8321
- PR-AUC: 0.9413
Training was done manually with PyTorch on a MacBook Air M1 (CPU only, due to accelerate/MPS compatibility issues).
