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.

Sampling from the exponential distribution using independent Bernoulli variates

TL;DR: This paper shows that each bit of a fixed-point exponential random variate is an independent Bernoulli variate, allowing the bits to be generated in parallel, and is particularly useful for very high performance applications.

Learning Recommenders for Implicit Feedback with Importance Resampling

TL;DR: This paper proposes an Adaptive Sampling method based on Importance Resampling (AdaSIR for short), which is not only almost equally efficient and accurate for any recommender models, but also can robustly accommodate arbitrary proposal distributions.

Theory and implementation of a novel stochastic approach to coupled cluster

TL;DR: The diagCCMC algorithm as mentioned in this paper performs an imaginary-time propagation of the similarity-transformed coupled cluster Schrodinger equation, where each term is evaluated as a randomly realized diagram in the connected expansion of the Hamiltonian.

Non-Periodic Corner Tilings in Computer Graphics

TL;DR: This dissertation investigates the use of corner tiles with color-coded corners, and presents efficient algorithms to perform such a tiling that are both more flexible and less prone to artifacts than existing algorithms.

Pseudonoise with Arbitrary Amplitude Distribution--Part I: Theory

TL;DR: A new sampling method, conditional bit sampling, which is suited for hardwired sampling devices because of its generality, simplicity, and accuracy, and agreement between actual and theoretical performance was excellent.
