AlphaRAD: Grounded Zero-Shot Classification in Chest Radiology via $\alpha$-Corrected Binary Cross Entropy and Factorized Latent Supervision
AI InsightAlphaRAD moves away from heuristic pairing by using LLM-parsed structured concept space to denoise contrastive learning. This suggests that zero-shot classification in medical imaging is shifting from hard alignment toward semantically constrained soft supervision. If spatial grounding proves effective, it may facilitate interpretable AI adoption in clinical workflows.Key TakeawayZero-shot classification in medical imaging is shifting from heuristic pair matching to structured semantic supervision.Why It MattersMedical imaging suffers from scarce and noisy labels, and heuristic pair matching in conventional contrastive learning often introduces erroneous supervision. If AlphaRAD's approach proves effective, it could enhance the usability of zero-shot models on real clinical data and push more medical imaging AI toward interpretable spatial grounding.Who's Affected- Medical Imaging AI ResearchersGain a new method to reduce noise in contrastive learning, potentially improving zero-shot classification performance and interpretability.
- Radiology AI Product TeamsIf validated on real data, it may reduce reliance on large labeled datasets and accelerate product deployment.
