Where the Bee Sucks -- A Dynamic Bayesian Network Approach to Decision Support for Pollinator Abundance Strategies

no code implementations5 Dec 2022 Martine J. Barons, Aditi Shenvi

For policymakers wishing to make evidence-based decisions, one of the challenges is how to combine the relevant information and evidence in a coherent and defensible manner in order to formulate and evaluate candidate policies.

cegpy: Modelling with Chain Event Graphs in Python

1 code implementation21 Nov 2022 Gareth Walley, Aditi Shenvi, Peter Strong, Katarzyna Kobalczyk

However, there currently exists no software that allows a user to leverage the theoretical developments of the CEG model family in modelling processes with structural asymmetries.

Beyond Conjugacy for Chain Event Graph Model Selection

no code implementations7 Nov 2022 Aditi Shenvi, Silvia Liverani

Moreover, we also show that this methodology is more amenable to being robustly scaled than the existing model selection algorithms used for this family.

A Bayesian decision support system for counteracting activities of terrorist groups

no code implementations8 Jul 2020 Aditi Shenvi, F. Oliver Bunnin, Jim Q. Smith

Activities of terrorist groups present a serious threat to the security and well-being of the general public.

Constructing a Chain Event Graph from a Staged Tree

no code implementations29 Jun 2020 Aditi Shenvi, Jim Q. Smith

This coloured event tree, also known as a staged tree, is the output of the learning algorithms used for this family.

Propagation for Dynamic Continuous Time Chain Event Graphs

no code implementations29 Jun 2020 Aditi Shenvi, Jim Q. Smith

Chain Event Graphs (CEGs) are a family of event-based graphical models that represent context-specific conditional independences typically exhibited by asymmetric state space problems.
