Scalable Bayesian Network Structure Learning with Splines

no code implementations27 Oct 2021 Charupriya Sharma, Peter van Beek

The graph structure of a Bayesian network (BN) can be learned from data using the well-known score-and-search approach.

A Score-and-Search Approach to Learning Bayesian Networks with Noisy-OR Relations

1 code implementation3 Nov 2020 Charupriya Sharma, Zhenyu A. Liao, James Cussens, Peter van Beek

A Bayesian network can be learned from data using the well-known score-and-search approach, and within this approach a key consideration is how to simultaneously learn the global structure in the form of the underlying DAG and the local structure in the CPDs.

Learning All Credible Bayesian Network Structures for Model Averaging

no code implementations27 Aug 2020 Zhenyu A. Liao, Charupriya Sharma, James Cussens, Peter van Beek

However, selecting a single model (i. e., the best scoring BN) can be misleading or may not achieve the best possible accuracy.

Finding All Bayesian Network Structures within a Factor of Optimal

no code implementations12 Nov 2018 Zhenyu A. Liao, Charupriya Sharma, James Cussens, Peter van Beek

However, selecting a single model (i. e., the best scoring BN) can be misleading or may not achieve the best possible accuracy.

Improved Image Selection for Stack-Based HDR Imaging

no code implementations19 Jun 2018 Peter van Beek

Stack-based high dynamic range (HDR) imaging is a technique for achieving a larger dynamic range in an image by combining several low dynamic range images acquired at different exposures.

Exploiting Structure in Weighted Model Counting Approaches to Probabilistic Inference

no code implementations16 Jan 2014 Wei Li, Pascal Poupart, Peter van Beek

Previous studies have demonstrated that encoding a Bayesian network into a SAT formula and then performing weighted model counting using a backtracking search algorithm can be an effective method for exact inference.
