Emotional Modulation in Swarm Decision Dynamics
David Freire-Obregón
Collective decision-making in biological and human groups often emerges from simple interaction rules that amplify minor differences into consensus. The bee equation, developed ini…
Dynamic Dropout: Leveraging Conway's Game of Life for Neural Networks Regularization
David Freire-Obregón, José Salas-Cáceres, Modesto Castrillón-Santana
Regularization techniques play a crucial role in preventing overfitting and improving the generalization performance of neural networks. Dropout, a widely used regularization techn…
Modeling Cultural Bias in Facial Expression Recognition with Adaptive Agents
David Freire-Obregón, José Salas-Cáceres, Javier Lorenzo-Navarro +3
Facial expression recognition (FER) must remain robust under both cultural variation and perceptually degraded visual conditions, yet most existing evaluations assume homogeneous d…
Wrong Face, Wrong Move: The Social Dynamics of Emotion Misperception in Agent-Based Models
David Freire-Obregón
The ability of humans to detect and respond to others' emotions is fundamental to understanding social behavior. Here, agents are instantiated with emotion classifiers of varying a…
