Parallel Sampling for Efficient High-dimensional Bayesian Network Structure Learning

1 code implementation19 Feb 2022 Zhigao Guo, Anthony C. Constantinou

This paper describes an approximate algorithm that performs parallel sampling on Candidate Parent Sets (CPSs), and can be viewed as an extension of MINOBS which is a state-of-the-art algorithm for structure learning from high dimensional data.

Effective and efficient structure learning with pruning and model averaging strategies

no code implementations1 Dec 2021 Anthony C. Constantinou, Yang Liu, Neville K. Kitson, Kiattikun Chobtham, Zhigao Guo

Learning the structure of a Bayesian Network (BN) with score-based solutions involves exploring the search space of possible graphs and moving towards the graph that maximises a given objective function.

The impact of prior knowledge on causal structure learning

no code implementations31 Jan 2021 Anthony C. Constantinou, Zhigao Guo, Neville K. Kitson

Because the value of knowledge depends on what data are available, we illustrate the results both with limited and big data.

Improving Bayesian Network Structure Learning in the Presence of Measurement Error

1 code implementation19 Nov 2020 Yang Liu, Anthony C. Constantinou, Zhigao Guo

Structure learning algorithms that learn the graph of a Bayesian network from observational data often do so by assuming the data correctly reflect the true distribution of the variables.

Approximate learning of high dimensional Bayesian network structures via pruning of Candidate Parent Sets

no code implementations8 Jun 2020 Zhigao Guo, Anthony C. Constantinou

The results illustrate how different levels of pruning affect the learning speed relative to the loss in accuracy in terms of model fitting, and show that aggressive pruning may be required to produce approximate solutions for high complexity problems.
