Base Model Perception and Fine-Tuning

Domain-specific supervised fine-tuning improved some specialized tasks, especially ECG analysis. The final system favored a strong general-purpose base model plus inference-time state-aware reasoning because fine-tuning degraded some consultation qualities and risked catastrophic forgetting. The researchers tested whether base models could perceive isolated medical artifacts before building the dialogue system. Gemini 2.0 Flash was generally considered perceptually grounded enough to support AMIE.
