Generative models for sequential dynamics in active inference

T Parr, K Friston, G Pezzulo - Cognitive Neurodynamics, 2023 - Springer
A central theme of theoretical neurobiology is that most of our cognitive operations require
processing of discrete sequences of items. This processing in turn emerges from continuous …
