Chest X-ray report generation moves to question-answer output: predicted disease labels align image and text representations, a medical knowledge graph supplies retrieved evidence, and a fine-tuned LLM rewrites the result, outperforming prior methods on most metrics on MIMIC-CXR and IU X-Ray.

The authors present BRAHMa, which converts Galaxy Zoo 3D volunteer bar masks into rotated-rectangle labels at a threshold calibrated against the Hoyle catalogue, fine-tunes a YOLO11x oriented-box detector on per-galaxy contrast-enhanced DESI Legacy images, and reproduces Hoyle bar lengths for 3150 galaxies with a mean absolute error of 1.14 kpc and Pearson 0.91 after a linear correction, close to the 0.99 kpc at which the two human catalogues agree, with no mask, threshold or fit at inference.
