Structured intermediate supervision improves reasoning accuracy across legal and medical QA
Researchers propose DAIS, a training framework that restructures intermediate supervision for reasoning tasks by converting teacher rationales into stage-level question-answer pairs. Rather than optimizing a single flat reasoning path, each intermediate step predicts a local conclusion conditioned only on prior states needed for that decision, while preserving the original task format at evaluation. Testing across legal, medical, and logical reasoning benchmarks with Qwen models shows consistent accuracy gains over standard chain-of-thought and answer-only baselines. The approach addresses a fundamental limitation in current CoT training: how to signal which prior conclusions actually matter for downstream reasoning steps.62
