Hi all, I have isolated a relatively lightweight example where I find that HMC is *significantly* outperforming PT. I tested most variations supported in Pigeons: Slice Sampler & AutoMALA, fixed, vari…

From f2f discussion with @kokbent he noted that a large proportion of the sampling time in NUTS was during early sampling. This contributes to very long sampling times overall (many hours to get to 40…

Sometimes, KDE tends to oversmooth the PDF, which introduces bias in the estimated PDF. Inverse-transform sampling doesn't have this issue, but it is usually implemented in 1D. This package extends it…

I was wondering if it is possible for you to add posterior sampling to PVAE model. The problem with prior sampling is that the embedding space could be sparse and in this case prior sampling would do …

**What we have already**
In CUQIpy, gradient-based sampling methods (including NUTS) can use FD gradient. This is done by enabling the FD gradient for the target before pas…

Hi there,
I was experimentng with jax sampling and instead of running successive calls to sample_smc_blackjax (which I thought would be useful to compare the posteriors and enable rhat-like diagno…

**Describe the bug**
This is a duplicate of https://github.com/sbi-dev/sbi/issues/1158 which was supposedly fixed by https://github.com/sbi-dev/sbi/pull/1179
When importing `posterior_nn` or any o…

Posterior predictive sampling takes considerably longer than model estimation itself, and that's completely unreasonable!
Last time I tried, the new [`fast_sample_posterior_predictive`](https://githu…
