🧠 Bayesian Brains and the Rényi Divergence

We used the Renyi variational inference to evaluate differences in posterior estimates and agent behaviour.

Numerical posterior estimation:

python main.py --configs unisim 

Multiarmed Bandits:

python main.py --configs mabsim 
python main.py --configs multisim
