Bayesian model learning Concept and motivation Concept learning is the process by which an agent discovers concepts underlying its perceptions. We argue that concept learning = latent variable discovery FRAMEWORK: Bayesian model learning QUESTIONS: Does Bayesian model learning account for human performance? Does human performance follow the Bayesian model learner or the widely known associative learner?
