Dermatology Reasoning Dataset — Full Reasoning

This is the full_reasoning ablation variant of danielfdias98/derm-reasoning, republished as a standalone repo so it can be plugged directly into a trainer without picking a config.

The assistant turn for every row contains: structured chain-of-thought clinical reasoning (diagnosis + observation + morphology + color + texture + border + location + size + reasoning).

Quick load

from datasets import load_dataset
ds = load_dataset("danielfdias98/derm-reasoning-full-reasoning")
print(ds)  # DatasetDict {train: 25_637, val: 2_849}

Sister repo

The complementary ablation variant is at danielfdias98/derm-reasoning-label-only. Same train/val split (95/5, seed=42), same images, just different assistant-turn density.

Image sources

The combined parent repo has the full per-source attribution table and image-redistribution split (public-redistributable + private-full image sets). See danielfdias98/derm-reasoning for the canonical README, citations, and download_images.py script.
