PriorNet: Prior-Guided Engagement Estimation from Face Video
Researchers have developed PriorNet, a novel framework designed to improve engagement estimation from face videos. This system addresses challenges like incomplete facial data and subjective annotations by incorporating task-specific priors at multiple stages of the process. PriorNet utilizes techniques such as zero-frame placeholders for missed detections, parameter-efficient adaptation of a pre-trained backbone, and a specialized training objective to enhance accuracy.
