Causal Unit Selection using Tractable Arithmetic Circuits

no code implementations10 Apr 2024 Haiying Huang, Adnan Darwiche

The unit selection problem aims to find objects, called units, that optimize a causal objective function which describes the objects' behavior in a causal context (e. g., selecting customers who are about to churn but would most likely change their mind if encouraged).

Identifying Causal Effects Under Functional Dependencies

no code implementations7 Mar 2024 Yizuo Chen, Adnan Darwiche

We study the identification of causal effects, motivated by two improvements to identifiability which can be attained if one knows that some variables in a causal graph are functionally determined by their parents (without needing to know the specific functions).

An Algorithm and Complexity Results for Causal Unit Selection
