  • 大家一起来完善官方教程汉化版 - Tutorials - 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,。
  • Potential issue with SVI using init_params argument - numpyro - Pyro . . .
    I’m trying to utilize SVI with the AutoDelta guide I run the optimization for a certain number of steps, and save the final parameters to a dictionary and check if the parameters have converged to my liking If not, when I re-run the optimization (with a reduced learning rate), and pass in the last saved parameters as initial parameters for this new optimization stage, the init_loss printed
  • Bad performance Bayesian Convolutional Neural Network - Misc. - Pyro . . .
    Hello Pyro community, I’m trying to build a Bayesian CNN for MNIST classification using Pyro, but despite seeing the ELBO loss decrease to around 10 during training, the model’s predictive accuracy remains at chance level (~10%) Could you help me understand why the loss improves while performance doesn’t, and suggest potential fixes? Code Overview: import torch import pyro import pyro
  • 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
  • Unexpectedly different outcomes when initializing via NUTS or MCMC
    I’m finding that setting initial parameter values through NUTS or through MCMC gives different results, even though they should be the same I’ve checked that the parameter values are initialized to be the same from the first sample taken in a run either using nuts_kernel = NUTS(model, dense_mass=dense_mass, max_tree_depth=6, init_strategy=init_to_value sampler = MCMC(nuts_kernel, num

  • Batch processing numpyro models using Ray - numpyro - Pyro Discussion Forum
    Hello again, Related post: Batch processing Pyro models so cc: @fonnesbeck as I think he’ll be interested in batch processing Bayesian models anyway I want to run lots of numpyro models in parallel I created a new post because: this post uses numpyro instead of pyro I’m doing sampling instead of SVI I’m using Ray instead of Dask that post was 2021 I’m running a simple Neal’s funnel

  • Is `callback` supported for numpyro NUTS sampler? - numpyro - Pyro . . .
    Hi all, I’m using Numpyro as a NUTS sampler in a PyMC model and would like to add a callback to monitor the number of divergences and stop the sampling when it’s greater than X amount of divergences I found this response in the PyMC and want to know if that has changed or if there is a way to do it now This could be only in PyMC but already asked there #7419 🙂 sample_numpyro_nuts does
