Researchers have developed a new framework for personalizing human activity recognition (HAR) models on wearable devices. This gradient-free approach repurposes existing HAR classifiers to adapt to new users with minimal calibration data, even when that data is unlabeled or unavailable. The method demonstrated significant improvements in accuracy, with supervised adaptation boosting performance by up to 33.44 percentage points and unsupervised adaptation by up to 32.13 percentage points.
