TLDR
The fast generation of discrete random variables with arbitrary frequency distributions is discussed, related to rejection techniques but differs from them in that all samples comprising the input data contribute to the samples in the target distribution.
Abstract
The fast generation of discrete random variables with arbitrary frequency distributions is discussed. The proposed method is related to rejection techniques but differs from them in that all samples comprising the input data contribute to the samples in the target distribution. The software implementation of the method requires at most two memory references and a comparison. The method features good accuracy and modest storage requirements. I t is particularly useful in small computers with limited memory capacity.

Scaling up Dynamic Topic Models

TL;DR: In this article, the Gibbs sampling with stochastic gradient Langevin dynamics (GSDL) algorithm is used to learn the dynamics of 1,000 topics from 2.6 million documents in less than half an hour and their empirical results show that their algorithm is not only orders of magnitude faster than the baselines but also achieves lower perplexity.
