  • 大家一起来完善官方教程汉化版 - Pyro Discussion Forum
    要做一些高斯过程相关的研究，刚接触pyro， 浏览了你的Introduction部分，能在翻译原教程的基础上加入概率图和重点提炼等以帮助理解，着实不错，当然这也是我个人觉得汉化教程最应该具有的闪光点，。
  • Shape mismatch - Misc. - Pyro Discussion Forum
    Hi, I am very new to SVI and Pyro in general I am trying to implement a simple model which could be seen as an extension of the gaussian mixture example The setup of the problem is as follows: We have N individuals w…
  • Use of LogNormal in Numpyro - Pyro Discussion Forum
    Hi everyone, I am very new to Numpyro and hierarchical modeling Recently I have been trying to build a hierarchical model where I have a hyper-prior (theta_group) which should be centered around 1 and strictly positive There is another prior (theta_part) which should be centered around theta_group I am trying to use LogNormal as priors for both: theta_group = numpyro sample("theta_group
  • Diagnosing convergence for a very simple model - numpyro - Pyro . . .
    I’ve been trying to monitor convergence of model parameters using the cosine similarity between changes of parameter values The basic idea is as follows If the variational parameters are very far from the optimum, the optimizer will consistency push the parameters in the right direction and the similarity between changes is large If the variational parameters are close to the optimum
  • Adam optimizer before NUTS? - Pyro Discussion Forum
    I’m trying to infer the parameters of a non-linear ODE system Would using a gradient descent optimizer like Adam (eg from optax) to initialize the guess starting point for NUTS be useful? Is something like this already implemented in numpyro? I’m finding that the time to convergence for my NUTS inference is very sensitive to how small my uncertainties are that go into my Gaussian
  • Variational Inference for Dirichlet process clustering - Pyro . . .
    Hi there! This is my first time using Pyro so I am very excited to see what I can built with it 🙂 Specifically, I am trying to do finite Dirichlet Process clustering with Variational Inference I want to generalize this into a Chinese Restaurant Process involving an “infinite” number of states But for now, I am just generating 1-D data from 3 Gaussians with proportions given by a
  • Moving MCMC from CPU to GPU - Pyro Discussion Forum
    Hi all, I’ve read a few posts on the forum about how to use GPU for MCMC: Transfer SVI, NUTS and MCMC to GPU (Cuda), How to move MCMC run on GPU to CPU and Training on single GPU, but there are a few questions I still have on how to get the most out of numpyro There is also this blog post comparing MCMC sampling methods on GPU, and although the model is built in pymc, it uses numpyro
