A 22-year-old woman presents with a significant weight loss, recurrent vomiting without diarrhea, and amenorrhea over the past 6 months.

Medical Chain-of-Thought (CoT) Dataset
A curated, partitioned dataset designed for fine-tuning and benchmarking Large Language Models (LLMs) on clinical diagnostics, pathophysiological deduction, and DeepSeek-R1-style long-form reasoning (<think>...</think>).
π Dataset Summary
- Source: Derived and partitioned from
ty-kim/medical_cot. - Total Instances: 2,000 clinically rich medical problem scenarios.
- Partitions:
train: 1,800 examples (90%) for supervised fine-tuning (SFT).test: 200 examples (10%) reserved as a strictly held-out evaluation benchmark.
- Partition Seed:
42(reproducible split).
π― Purpose & Research Motivation
Standard instruction tuning often encourages models to jump immediately to a final diagnosis, risking diagnostic hallucination and missing critical contraindications. This dataset enables training and evaluating models with structured internal reasoning:
- Intermediate Diagnostic Hypotheses: Formulating plausible differential hypotheses from patient vitals and presentation before committing to a diagnosis.
- Evidence Utilization: Connecting subtle symptoms, patient history, and physical findings into coherent pathophysiological arguments.
- Contradiction Handling: Identifying conflicting signs and justifying why tempting competing conditions are ruled out.
- Self-Reflection & Backtracking: Actively auditing intermediate deductions (e.g., "Wait, let me double-check this mechanism...") before producing the final recommendation.

π¬ Experimental Ladder & Ablation Studies
This dataset is designed to benchmark models across a 4-tier experimental ladder:
- Tier 0 (Zero-Shot Base): Evaluate base model (e.g.
Mistral-7B-Instruct-v0.3) without any SFT. - Tier 1 (Direct SFT): Train on
text_directto establish domain adaptation baseline. - Tier 2 (Standard CoT SFT): Train on
text_cotto measure gains from<think>tokens. - Tier 3 (Progressive Weighted Loss): Train on
text_cotwith differential token supervision:<think>trigger tag:0.25- Reasoning tokens:
0.50 </think>closing tag:0.75- Final diagnosis answer:
1.00
