Hi

I am wondering how can I have a tempered posterior using Pyro/Numpyro.

For example: The origin model is p(w, z) = p(w | z) p(z), and I would like to change the likelihood term to p(w | z)^T.

This tempering operation similar to the KL annealing trick adopted in VAE and the cold posterior trick used in BNN training.

Thanks
