This study proposes a computational model for categorization, explaining how the brain infers causes and generalizes learning. It highlights the importance of environmental statistics and accuracy-complexity trade-offs in Bayesian brain function.

Area of Science:

  • Cognitive Science
  • Computational Neuroscience
  • Artificial Intelligence

Background:

  • Categorization is crucial for efficient behavior and generalization.
  • The brain may operate using Bayesian inference with generative models.

Purpose of the Study:

  • To propose a computational model of categorization based on Bayesian inference.
  • To elucidate emergent properties of categorization within the Bayesian brain hypothesis.

Main Methods:

  • Developing a computational model of categorization.
  • Integrating principles of Bayesian inference and generative models.
  • Considering environmental statistics, context, and action representations.

Main Results:

  • The model infers latent causes of sensory experience.
  • It demonstrates a hierarchical organization of latent causes.
  • It explicitly includes context and action representations.

    • Conclusions:

    • The proposed model aligns with the Bayesian brain hypothesis.
    • Categorization emerges from optimizing generative models based on accuracy-complexity trade-offs.
    • This work advances understanding of computational principles underlying categorization.
