An arXiv preprint on LLM judge reliability evaluation is now available
The preprint “LLM Judges Have Dark Current: A Psychometric Datasheet for LLM-as-a-Judge Evaluation” is now available on arXiv. The work treats LLM-as-a-judge systems as measurement instruments rather than scalar accuracy or agreement devices, and proposes a Judge Datasheet protocol for measuring dark current, positional bias, target sensitivity, and criterion shift.

A paper on an AI arteriosclerosis diagnosis system was published in Journal of Comprehensive Engineering
A paper on an AI arteriosclerosis diagnosis system using RLHF and adversarial attack was published in Vol. 38 of Journal of Comprehensive Engineering. The study evaluates the robustness of IMT extraction from carotid ultrasound images under adversarial perturbations, focusing on whether attention remains on physician-relevant structures.
