Adaptive approximate Bayesian computation for complex models [PDF]

open access: yes, 2013
Approximate Bayesian computation (ABC) is a family of computational techniques in Bayesian statistics. These techniques allow to fi t a model to data without relying on the computation of the model likelihood.

An overview on Approximate Bayesian computation [PDF]

open access: yesESAIM: Proceedings, 2014
Approximate Bayesian computation techniques, also called likelihood-free methods, are one of the most satisfactory approach to intractable likelihood problems.

ABrox-A user-friendly Python module for approximate Bayesian computation with a focus on model comparison. [PDF]

open access: yesPLoS ONE, 2018
We give an overview of the basic principles of approximate Bayesian computation (ABC), a class of stochastic methods that enable flexible and likelihood-free model comparison and parameter estimation.

Pre-processing for approximate Bayesian computation in image analysis [PDF]

open access: yes, 2014
Most of the existing algorithms for approximate Bayesian computation (ABC) assume that it is feasible to simulate pseudo-data from the model at each iteration.

Approximate Bayesian Computation for a Class of Time Series Models [PDF]

open access: yes, 2014
In the following article we consider approximate Bayesian computation (ABC) for certain classes of time series models. In particular, we focus upon scenarios where the likelihoods of the observations and parameter are intractable, by which we mean that ...

Application of the Approximate Bayesian Computation Algorithm to Gamma-Ray Spectroscopy

open access: yesAlgorithms, 2020
Radioisotope identification (RIID) algorithms for gamma-ray spectroscopy aim to infer what isotopes are present and in what amounts in test items. RIID algorithms either use all energy channels in the analysis region or only energy channels in and near ...

Interpreting scratch assays using pair density dynamics and approximate Bayesian computation [PDF]

open access: yesOpen Biology, 2014
Quantifying the impact of biochemical compounds on collective cell spreading is an essential element of drug design, with various applications including developing treatments for chronic wounds and cancer.

Constructing Summary Statistics for Approximate Bayesian Computation: Semi-Automatic Approximate Bayesian Computation [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2012
Summary Many modern statistical applications involve inference for complex stochastic models, where it is easy to simulate from the models, but impossible to calculate likelihoods. Approximate Bayesian computation (ABC) is a method of inference for such models.

Correcting Approximate Bayesian Computation [PDF]

open access: yesTrends in Ecology & Evolution, 2010
In their review of approximate Bayesian computation (ABC), Csillery et al. [pg. 411, 1] stated that my [2] “main” objections to ABC are that inference is limited to a finite set of models, and that these models are generally complex, although they failed to state the reasons for my objections. Csillery et al.
