biosqi
explainable, calibrated signal-quality assessment for ECG, PPG and EEG
What is biosqi?
biosqi is an open-source Python library that scores the quality of long ECG, PPG and EEG recordings window by window and explains each decision, flagging evidence of mains interference, baseline wander or motion, clipping, dropout, unusual amplitude and poor beat consistency. It has a typed Python API, a command-line tool, HTML reports and a local dashboard, and its scores come from calibrated, versioned models.
