Bayesian Models of Perception, Cognition, and Learning
Bayesian Models of Perception, Cognition, and Learning
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.
