Causal knowledge engineering: A case study from COVID-19

no code implementations21 Mar 2024 Steven Mascaro, Yue Wu, Ross Pearson, Owen Woodberry, Jessica Ramsay, Tom Snelling, Ann E. Nicholson

The unique challenges of the setting lead to experiments with the elicitation approach, and what emerged was a knowledge engineering method we call Causal Knowledge Engineering (CKE).

The practice of qualitative parameterisation in the development of Bayesian networks

no code implementations20 Feb 2024 Steven Mascaro, Owen Woodberry, Yue Wu, Ann E. Nicholson

Since the practice focuses on qualitative issues, despite being quantitative in nature, we call this step qualitative parameterisation and provide an outline of its role in the BN development process.

Latent Variable Discovery Using Dependency Patterns

no code implementations22 Jul 2016 Xuhui Zhang, Kevin B. Korb, Ann E. Nicholson, Steven Mascaro

The causal discovery of Bayesian networks is an active and important research area, and it is based upon searching the space of causal models for those which can best explain a pattern of probabilistic dependencies shown in the data.
