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…
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…
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…
