Draft paper uses Markov-chain eigenfunctions to build partitions and speed up sampling

michaelchchoi · x · 2026-07-21

A work-in-progress paper proposes using the bottom eigenfunction of a Markov chain to build a partition that speeds up sampling.

Core idea

Why it matters

The technique is aimed at improving mixing by structuring the chain around spectral information, rather than relying on the sampler to discover the partition on its own.

The author says a draft is available and that the work is still in progress, with feedback invited.
