We build and study machine learning systems across vision, language, and medicine.

We look at where they succeed, where they fail, and how far their confidence can be trusted.

Vision. Language. Medicine.

Our mission

We build machine learning systems in vision, language, and medicine, then we study them: where they succeed, where they break, and how far their confidence can be trusted.

Vision

Building vision and medical-imaging models, then measuring exactly which classes or patients they still fail on.

Language

Building language systems, then measuring where they break down and the hidden costs baked into how we tokenize text.

Medicine

Building clinical-adjacent models, from CT segmentation to ECG classifiers, then studying their calibration and error structure.

Minority-Class Failure and Confidence Miscalibration in ECG Classification

Seven classifiers audited across three independent ECG datasets, errors concentrate in minority classes and specific patients, and confidence is not a reliable guide to correctness.
