Different data mining algorithms and data labeling techniques have been used generating 735 prediction models. Results so far show that predictive models on affective state detection from multimodal-based approaches provide better accuracy rates than single-based.eninfo:eu-repo/semantics/closedAccess3304 Tecnología de los ordenadoresactas de congresoArtificial intelligenceAffective computingdata miningHuman- computer interactionAdaptive systemsUser modelingMachine learningMultimodal approachSensor data
