Micro-DualNet: Dual-Path Spatio-Temporal Network for Micro-Action Recognition
Naga VS Raviteja Chappa, Evangelos Sariyanidi, Lisa Yankowitz +4
Micro-actions are subtle, localized movements lasting 1-3 seconds such as scratching one's head or tapping fingers. Such subtle actions are essential for social communication, ubiq…
Concurrence: A dependence criterion for time series, applied to biological data
Evangelos Sariyanidi, John D. Herrington, Lisa Yankowitz +8
Measuring the statistical dependence between observed signals is a primary tool for scientific discovery. However, biological systems often exhibit complex non-linear interactions…
Bitbox: Behavioral Imaging Toolbox for Computational Analysis of Behavior from Videos
Evangelos Sariyanidi, Gokul Nair, Lisa Yankowitz +8
Computational measurement of human behavior from video has recently become feasible due to major advances in AI. These advances now enable granular and precise quantification of fa…
Measuring Dependencies between Biological Signals with Self-supervision, and its Limitations
Evangelos Sariyanidi, John D. Herrington, Lisa Yankowitz +6
Measuring the statistical dependence between observed signals is a primary tool for scientific discovery. However, biological systems often exhibit complex non-linear interactions…
Beyond FACS: Data-driven Facial Expression Dictionaries, with Application to Predicting Autism
Evangelos Sariyanidi, Lisa Yankowitz, Robert T. Schultz +3
The Facial Action Coding System (FACS) has been used by numerous studies to investigate the links between facial behavior and mental health. The laborious and costly process of FAC…
