Abstract
Modeling of human emotion is a challenging problem that can require
multiple signals types, as well as contextual information that has been
obtained over time. Considering this, in this paper we present our
approach, based on physiological signals, to the Emotion Physiology and
Experience Collaboration (EPIC) challenge at Affective Computing &
Intelligent Interaction (ACII), 2023. In total there are four scenarios
that we model: 1) across time; 2) across subjects; 3) across elicitor;
and 4) across version. To tackle this challenge, we propose to use a
physiological fusion-based approach to solve each scenario. Along with
this, we give a detailed analysis of the evaluated physiological signals
and personalized predictions for each subject are shown. Our proposed
approach shows encouraging results with the lowest root mean square
error achieved for scenario 4 (across version) for both valence and
arousal on the challenge test set.
