Abstract
This study presents a framework that models participant heterogeneity and the economic value of additional calibration labels to improve activity recognition.
Reality Card
Core Claim
HB-PVI achieved utility-optimal performance in 199 of 216 cost-threshold settings, advocating for a population-first deployment policy when personalization gains are minimal.
Method / Result
One-step EVSI was zero at every decision state, leading to a 100% reduction in labeling while maintaining a posterior mean F1 loss of 0.00217.
Limitations
The study's findings may be limited by the specific cohort size (47 participants) and the context of the MUSIC-CAR dataset.
