Composable by default
Metrics, datasets, and uncertainty estimates work together without requiring custom pipelines.
Software · Library
A PyTorch library for measurement science. Includes IRT models (Rasch, 2PL, 3PL), computerized adaptive testing, psychometric metrics, and GPU-accelerated estimation.
Design principles
Three commitments shape every part of the library.
Metrics, datasets, and uncertainty estimates work together without requiring custom pipelines.
Every output makes its assumptions visible. Results always include uncertainty and comparability information.
Researchers across institutions can adopt, extend, and contribute back to shared infrastructure.
