Jan 15, 2025 · Hi all, I’m still quite new to Numpyro and I’ve been trying to fit a simple time to event model on some simulated data. The definition of the model is as follows

Nov 7, 2018 · Usually you’d use fixed “prior” parameters in the model and learnable “posterior” parameters in the guide, and only the learnable parameters would require pyro.param …

Mar 4, 2019 · In Pyro, it is required that “All dimensions must be declared either dependent or conditionally independent.” You can take a look at tensor shape tutorial to get a sense of it.

Mar 10, 2021 · It seems numpyro can model latent integers using funsor, great. In this example I want to model 2 latent groups using Dirichlet and Categorical. I am struggling with the ii …

Jan 11, 2021 · Hi all, What is the best way to save the MCMC results. Let’s say we successfully performed our inference with mcmc.run (in my case on remote server) and now I want to save …

Jan 10, 2021 · Hello I was wondering if it’s possible to parallelize the number of particles used to estimate the ELBO over multiple GPUs (i.e. num_particles=40, and if we have 4 GPUs, then …

Apr 2, 2020 · please search this forum for “bayesian neural networks” and read those posts, for example this post or this post. that medium post actually contains some regrettable technical …
