Iterative Feature Normalization Scheme for Automatic Emotion Detection from Speech
Found in: IEEE Transactions on Affective Computing
By Carlos Busso,Soroosh Mariooryad,Angeliki Metallinou,Shrikanth Narayanan
Issue Date:October 2013
pp. 386-397
The externalization of emotion is intrinsically speaker-dependent. A robust emotion recognition system should be able to compensate for these differences across speakers. A natural approach is to normalize the features before training the classifiers. Howe...
Annotation and processing of continuous emotional attributes: Challenges and opportunities
Found in: 2013 10th IEEE International Conference on Automatic Face & Gesture Recognition (FG 2013)
By Angeliki Metallinou,Shrikanth Narayanan
Issue Date:April 2013
pp. 1-8
Human emotional and cognitive states evolve with variable intensity and clarity through the course of social interactions and experiences, and they are continuously influenced by a variety of input multimodal information from the environment and the intera...
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...
GridNews: A distributed automatic Greek broadcast transcription system
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By D. Dimitriadis, A. Metallinou, I. Konstantinou, G. Goumas, P. Maragos, N. Koziris
Issue Date:April 2009
pp. 1917-1920
In this paper, a distributed system storing and retrieving Broadcast News data recorded from the Greek television is presented. These multimodal data are processed in a grid computational environment interconnecting distributed data storage and processing ...
Audio-Visual Emotion Recognition Using Gaussian Mixture Models for Face and Voice
Found in: Multimedia, International Symposium on
By Angeliki Metallinou, Sungbok Lee, Shrikanth Narayanan
Issue Date:December 2008
pp. 250-257
Emotion expression associated with human communication is known to be a multimodal process. In this work, we investigate the way that emotional information is conveyed by facial and vocal modalities, and how these modalities can be effectively combined to ...
Evaluation of dynamic scheduling methods in simulations of storm-time ion acceleration
Found in: Parallel and Distributed Processing Symposium, International
By Ioannis Riakiotakis, Georgios Goumas, Nectarios Koziris, Fiori-Anastasia Metallinou, Ioannis A. Daglis
Issue Date:April 2008
pp. 1-8
In this paper we investigate the applicability of classic dynamic loop scheduling methods on a numerical simulation code that calculates the trajectories of charged particles in the earth’s magnetosphere. The numerical application under consideration inves...
