Incremental Inference on Higher-Order Probabilistic Graphical Models Applied to Constraint Satisfaction Problems

no code implementations25 Feb 2022 Simon Streicher

The first is a comparison between factor graphs and cluster graphs on graph colouring problems such as Sudokus - indicating a significant advantage for preferring cluster graphs.

Strengthening Probabilistic Graphical Models: The Purge-and-merge Algorithm

1 code implementation30 Sep 2021 Simon Streicher, Johan du Preez

It is in principle possible to convert loopy PGMs to an equivalent tree structure, but this is usually impractical for interesting problems due to exponential blow-up.

Plant-wide fault and disturbance screening using combined transfer entropy and eigenvector centrality analysis

no code implementations8 Apr 2019 Simon Streicher, Carl Sandrock

Finding the source of a disturbance or fault in complex systems such as industrial chemical processing plants can be a difficult task and consume a significant number of engineering hours.
