Computational Approaches to Access Probabilistic Population Codes for Higher Cognition an Decision-Making

no code implementations25 Apr 2019 Kevin Jasberg, Sergej Sizov

In recent years, research unveiled more and more evidence for the so-called Bayesian Brain Paradigm, i. e. the human brain is interpreted as a probabilistic inference machine and Bayesian modelling approaches are hence used successfully.
