This lesson gives an overview of Bayesian memory and learning, as well as how to go from observations to latent variables.

Topics covered in this lesson
  • Behavior.
  • Internal models in perception, probabilistic models.
  • Mathematical introduction.
  • Bayes' rule. Loss functions (a.k.a. utility functions).
  • Posterior mean and median, maximum a posteriori (MAP).
  • Behavioral examples.
  • Perception and likelihood ratio.
  • Bayesian estimation motor task, different strategies.
  • Combining priors and likelihood, different priors.
  • Natural (learned human) priors. Ideal observer model, inverting the ideal observer model to study natural priors/internal representations.
  • Cross-validation.
Prerequisites

Basic probablity theory
