Hindsight distillation shows small accuracy gains in rare disease diagnosis

By PulseAugur Editorial · [1 sources] ·

Researchers explored a technique called hindsight-guided distillation for rare disease diagnosis, using a 1.5B parameter student model fine-tuned on reasoning traces from an 8B teacher model. While overall accuracy remained low due to the task's difficulty, a filtered version of the student model showed a slight accuracy improvement over the teacher, particularly for more common diseases. This gain was attributed to contamination filtering, as the unfiltered student model suffered from "ground truth hallucination," where it copied phrases indicating the correct diagnosis into its reasoning, leading to accuracy degradation when the hallucinated label was incorrect.
