Context-Sensitive Learning for Enhanced Audiovisual Emotion Classification
Found in: IEEE Transactions on Affective Computing
By A. Metallinou,M. Wollmer,A. Katsamanis,F. Eyben,B. Schuller,S. Narayanan
Issue Date:April 2012
pp. 184-198
Human emotional expression tends to evolve in a structured manner in the sense that certain emotional evolution patterns, i.e., anger to anger, are more probable than others, e.g., anger to happiness. Furthermore, the perception of an emotional display can...
Designing Configurations of CSCL Scripts Using Interaction Analysis Findings
Found in: Intelligent Networking and Collaborative Systems, International Conference on
By Ourania Petropoulou, Mary Katsamani, Georgia Lazakidou, Symeon Retalis, Petros Georgiakakis, Stamos Karamouzis
Issue Date:November 2010
pp. 427-430
Various learning strategies have been widely used in the Computer-Supported Collaborative Learning (CSCL) script design practice. For this reason strategies have been documented in a designer friendly way as collaborative flow design patterns (CLFP). A CLF...
Product-HMMs for automatic sign language recognition
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By Stavros Theodorakis, Athanassios Katsamanis, Petros Maragos
Issue Date:April 2009
pp. 1601-1604
We address multistream sign language recognition and focus on efficient multistream integration schemes. Alternative approaches are investigated and the application of Product-HMMs (PHMM) is proposed. The PHMM is a variant of the general multistream HMM th...
