摘要:

Inferring causal effects and evaluating decision effects has attracted widespread attention in various fields. Under the framework of potential outcomes, unknown counterfactual outcomes and confounding factors are obstacles to making good individual treatment effect estimates. And most work assumes that the obtained covariates are all confounding factors, while it is difficult to guarantee in observational data. In response to the above issues, this article proposes a multitask learning framework called Decomposed-Representation based Causality Estimating Model (DRCEM), which identifies confounding factors by learning the decomposition representation of confounding and non-confounding factors, and ultimately estimates the causal effect in the observed data through a phased multitask training process. The experimental results on two public datasets show that our method performs well and outperforms existing causal effect estimation models. © 2024 ACM.
