CASE STUDY · YRI FELLOW

Published medical AI research on evaluation bias as a 9th grader

Neil examined how standard evaluation protocols inflate reported accuracy in nail abnormality detection models. He showed that random data splits allow leakage between training and test sets, and that models with near-perfect accuracy under random splits decline sharply when evaluated across different data sources. Region-of-interest training focused on the nail plate improved external F1-score and reduced background bias.

BEFORE THE FELLOWSHIP

A 9th grader at Mountain House High School who wanted to apply AI to real medical problems and publish his findings.

AFTER

Published research in medical image analysis with region-of-interest based bias mitigation.

The best part of YRI Fellowship was the positive attitude of the mentors, as they guided me to finish my research paper. The YRI Fellowship fosters a positive and inclusive environment where participants feel respected and supported. I was encouraged to share ideas and collaborate, which helps build strong connections and teamwork skills. Mentors are approachable and provide guidance that boosts confidence and growth. Overall, the program creates a space where individuals can learn, improve, and succeed together.
