We discuss generative and recognition models, the role of priors, variational inference, and how free energy principle explains some every day observations such as optical illusion. This is a high-level conceptual, rather than mathematical treatment. 🕒 OUTLINE: 00:00 Introduction 01:34 Role of world models 03:56 Free Energy as tradeoff between accuracy and complexity 05:20 Sponsor: Squarespace 06:35 Generative Model 10:03 Priors 12:18 Approximate Inference via Recognition Model 14:14 Free Energy balance revisited 16:34 Explanation for optical illusion 17:55 Review 📚 FURTHER READING & REFERENCES: Bogacz, Rafal. “A Tutorial on the Free-Energy Framework for Modelling Perception and Learning.” Journal of Mathematical Psychology 76 (February 2017): 198–211. https://doi.org/10.1016/j.jmp.2015.11.003.
