Researchers have developed GeoNIRS, a novel framework for pretraining functional near-infrared spectroscopy (fNIRS) data. This geometry-aware approach uses source-detector locations to create a shared spatial reference, enabling joint pretraining across diverse datasets with varying probe layouts and channel counts. GeoNIRS demonstrated superior performance on eight held-out tasks, outperforming conventional machine learning and fNIRS-specific baselines by improving average balanced accuracy by over 3 percentage points, particularly when labeled data is scarce.
