WEAR Dataset Challenge system uses stacked classifiers and count constraints

By PulseAugur Editorial · [1 sources] ·

This paper details an empirical analysis of a system developed for the 3rd WEAR Dataset Challenge, focusing on activity recognition from multimodal sensor data. The system employs stacked window classifiers and a mean-field decoder with a soft count constraint to label one-second windows of unseen participants' data. The analysis indicates that stacking features improved performance, and the count constraint provided a further, albeit smaller, boost. While a seam distance metric was explored, it did not significantly enhance the macro F1 score. AI

IMPACT This research contributes to activity recognition techniques using multimodal sensor data, potentially improving wearable device applications.

    An Error Budget for Shuffled Multimodal Windows in the 3rd WEAR Challenge: Stacking, Count Constraints and Seam Matching

    arXiv:2610.32398v1 Announce Type: new Abstract: The 3rd WEAR Dataset Challenge asks for an activity label for every one-second window of four unseen participants. Each window has 15 VideoMAEv2 frame embeddings, the accelerometer signal of one random limb, and the windows are shuf…
