Representing Time-Varying Cyclic Dynamics Using Multiple-Subject State-Space Models

Thursday, September 17th, 2009

Chow, S.-M., Hamaker, E. L., Fujita, F. & Boker, S. M. (2009) Representing Time-Varying Cyclic Dynamics Using Multiple-Subject State-Space Models. British Journal of Mathematical and Statistical Psychology. vol 62, 683-716.

THis article compares two contemporary state-space models for dynamical systems analysis: the stochastic cycle model and the dynamic harmonic regression model. These models are applied to two studies: one on postural dynamics and another daily diary study of affect. Publication rules for BJMSP prohibit us from quoting excerpts or distributing the manuscript on the web, but we can send a reprint if you send one of the authors an email request.

Brick, T.R., Hunter, M.D., & Cohn, J.F. Get The FACS Fast: Automated FACS face analysis benefits from the addition of velocity. 2009 International Conference on Affective Computing & Intelligent Interaction (ACII 2009)

This article reports that the accuracy of automatic recognition of FACS codes from video data can be improved by including velocity and acceleration of tracked points on faces from the Cohn-Kanade database.
