Title: Self-supervised Behavioral Imaging
Humans transmit social signals through a number of nonverbal cues, including gaze direction, facial expression, and body gesture. These cues are often subtle, e.g., microscopic facial muscle movements of cynical smiles, very difficult for AI to read. This poses a critical challenge in collecting, annotating, and learning from data. In this talk, I will present a few instances of our recent effort that addresses this challenge through self-supervised learning. This includes leveraging multiview geometry, temporal coherence, and semantic prior. To the end, I will discuss our new commercialization effort that pushes behavioral understanding in the wild.
