Fast free energy estimates from λ-dynamics with bias-updated Gibbs sampling [PDF]

open access: yesNature Communications, 2023
Relative binding free energy calculations have become an integral computational tool for lead optimization in structure-based drug design. Classical alchemical methods, including free energy perturbation or thermodynamic integration, compute relative ...

Exploring phylogenetic hypotheses via Gibbs sampling on evolutionary networks [PDF]

open access: yesBMC Genomics, 2016
Background Phylogenetic networks are leaf-labeled graphs used to model and display complex evolutionary relationships that do not fit a single tree. There are two classes of phylogenetic networks: Data-display networks and evolutionary networks.

Computational phase transition signature in Gibbs sampling

open access: yesJournal of Physics: Complexity, 2023
Gibbs sampling is fundamental to a wide range of computer algorithms. Such algorithms are set to be replaced by physics based processors—be it quantum or stochastic annealing devices—which embed problem instances and evolve a physical system into a low ...

PhyloGibbs-MP: module prediction and discriminative motif-finding by Gibbs sampling. [PDF]

open access: yesPLoS Computational Biology, 2008
PhyloGibbs, our recent Gibbs-sampling motif-finder, takes phylogeny into account in detecting binding sites for transcription factors in DNA and assigns posterior probabilities to its predictions obtained by sampling the entire configuration space. Here,

Gibbs-Slice Sampling Algorithm for Estimating the Four-Parameter Logistic Model

open access: yesFrontiers in Psychology, 2020
The four-parameter logistic (4PL) model has recently attracted much interest in educational testing and psychological measurement. This paper develops a new Gibbs-slice sampling algorithm for estimating the 4PL model parameters in a fully Bayesian ...

A Dirichlet Process Prior Approach for Covariate Selection

open access: yesEntropy, 2020
The variable selection problem in general, and specifically for the ordinary linear regression model, is considered in the setup in which the number of covariates is large enough to prevent the exploration of all possible models.
