Key research themes

1. How can appraisal-based neural network models advance our understanding and simulation of emotion elicitation and differentiation?

This theme focuses on the computational modeling of emotional processes guided by appraisal theories, specifically leveraging neural networks to simulate the elicitation, differentiation, and dynamic patterning of emotions. It addresses the challenge that traditional discrete and dimensional emotion models provide limited computational tractability, and explores the potential of componential models, such as the Component Process Model (CPM), to underpin neural architectures that capture the recursive appraisal mechanisms linking cognition and emotion.

Key finding: This paper presents the Component Process Model (CPM) as a highly specific appraisal-based emotion theory suitable for computational modeling using artificial neural networks. It argues that CPM's detailed postulations of... Read more

2. In what ways does integrating affective information enhance behavioral modeling and decision-making in intelligent environments?

This research strand investigates the incorporation of affective states—detected through physiological, behavioral, or contextual cues—into agent models operating in intelligent environments such as smart homes and learning systems. The goal is to improve agent adaptivity, personalize user interactions, and optimize decision-making by leveraging emotion-aware input. This includes both the development of affective models for user behavior prediction and the design of systems that respond appropriately to detected emotional states, thus illuminating the interplay between emotion, cognition, and control in pervasive computing.

Key finding: The study demonstrates that integrating valence-based emotional data into intelligent agents significantly improves the accuracy of user behavior modeling in smart homes compared to agents using raw physiological or no... Read more

3. What computational approaches most effectively model emotion recognition and dynamics from multimodal human signals?

This theme explores computational models designed for recognizing, categorizing, and simulating emotions based on multimodal inputs including facial expressions, speech, EEG signals, and behavioral data. It investigates statistical, probabilistic, and machine learning methods to capture the temporal dynamics of emotions and the challenges of modality integration. The research includes efforts to refine corpora, improve annotation paradigms, and develop real-time classifiers that advance the interpretability and robustness of emotion recognition systems relevant for human-computer interaction and affective computing applications.

Key finding: Utilizing Simulation Theory and findings from Mirror-Neuron Systems research, this work proposes a probabilistic model that maps observed facial expressions onto an internal latent space representing phenomenological... Read more
Key finding: This paper develops a Bayesian dynamic vector autoregressive model that jointly quantifies six elementary emotion dynamic features—including within-person variability, inertia, cross-lagged influences, and granularity—from... Read more
Key finding: By applying convolutional neural networks (CNNs) on mel-spectrogram inputs derived from speech audio, this work achieves effective classification of five emotional categories: anger, calm, anxiety, pleasure, and sorrow. The... Read more
Key finding: Visualizing EEG-based power spectral density features across multiple datasets revealed that subject-dependent components strongly dominate emotion-related components and that session dependency affects model generalization.... Read more
Key finding: This paper critically examines existing methodologies for emotional content generation and labeling in corpora used for affective computing, highlighting the challenges in capturing spontaneous, context-rich emotional... Read more
