The method accepts draft proposals sequentially - once a proposal is rejected, a maximal coupling is used to obtain a valid sample, and the process repeats.
re "still working with kernels" - see the other ICML 2025 paper, arxiv.org/abs/2502.02483 which uses distributional kernel scoring rules!

Composite Goodness-of-fit Tests with Kernels, now out in JMLR!

Test if your distribution comes from ✨any✨ member of a parametric family. Comes in MMD and KSD flavours, and with code.

Turns out that overfitting is the right approach when you want to generalize to new tasks!

Kernel Single Proxy Control for Deterministic Confounding
at #AISTATS25
Proxy causal learning generally requires two proxy variables - a treatment and an outcome proxy. When is it possible to use just one?

Credal Two-Sample Tests of Epistemic Uncertainty

Compare credal sets: convex sets of prob measures where elements capture aleatoric uncertainty; set represents epistemic uncertainty.

I already advertised for this document when I posted it on arXiv, and later when it was published.
This week, with the agreement of the publisher, I uploaded the published version on arXiv.
Less typos, more references and additional sections including PAC-Bayes Bernstein.
