Description

Techniques like SMC, Langevin sampling and MALA don't seem to be covered by numpyro out of the box. I am aware that using blackjax or TFP with an adapter is an option in some cases, but still feel that a numpyro-native implementation could lower the barrier to using a wider range of samplers and make modelling code more concise and self-contained. Would you be open to accepting contributions that implement these missing samplers? If positive in principle, very happy to discuss case by case here or in separate issues.

First steps

  1. Read the whole issue, then the project's contributing guide.

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

The issue names no files, tests, or entry points. First clarify which sampler—SMC, Langevin sampling, or MALA—is in scope and what maintainers would accept; completion would require a separately scoped NumPyro-native sampler contribution with appropriate project validation.
