Efficiently learning and sampling multimodal distributions with data-based initialization
Frederic Koehler, Holden Lee, Thuy-Duong Vuong
We consider the problem of sampling a multimodal distribution with a Markov chain given a small number of samples from the stationary measure. Although mixing can be arbitrarily sl…
Fast parallel sampling under isoperimetry
Nima Anari, Sinho Chewi, Thuy-Duong Vuong
We show how to sample in parallel from a distribution over that satisfies a log-Sobolev inequality and has a smooth log-density, by parallelizing the Langevin (re…
Sampling Multimodal Distributions with the Vanilla Score: Benefits of Data-Based Initialization
Frederic Koehler, Thuy-Duong Vuong
There is a long history, as well as a recent explosion of interest, in statistical and generative modeling approaches based on score functions -- derivatives of the log-likelihood…
Universality of Spectral Independence with Applications to Fast Mixing in Spin Glasses
Nima Anari, Vishesh Jain, Frederic Koehler +2
We study Glauber dynamics for sampling from discrete distributions on the hypercube . Recently, techniques based on spectral independence have successfully yielded…
Optimal mixing of the down-up walk on independent sets of a given size
Vishesh Jain, Marcus Michelen, Huy Tuan Pham +1
Let be a graph on vertices of maximum degree . We show that, for any , the down-up walk on independent sets of size mixes in time $O_{Δ,δ}(k\…
Toric Mutations in the dP Quiver and Subgraphs of the dP Brane Tiling
Yibo Gao, Zhaoqi Li, Thuy-Duong Vuong +1
Brane tilings are infinite, bipartite, periodic, planar graphs that are dual to quivers. In this paper, we examine the del Pezzo 2 (dP) quiver and its brane tiling, which arise…
