A deeper look at perceptual inference
In this post we will take a deeper look at how, according to the active inference theory, the brain interprets what it observes.
Active inference lecture notes
I have set out to gain some insights into the active inference theory that provides a unified framework for perception, learning, decision making, and action. I will share my “lecture notes” combined with my own comments in this and future posts. My focus is on the mathematical models and the necessary algorithms.
