Conditional treatment effect models under uncertainty of training data
Conditional treatment effect models estimate heterogeneous responses to interventions based on individual covariates, enabling personalized decision-making in clinical medicine, equipment maintenance, and economic policy. Estimating these effects typically involves dividing subjects (patients) into treatment and control groups and comparing their outcomes. However, a fundamental challenge in estimation is that an individual's counterfactual outcome is unobservable; we can only observe the outcome under either the treatment or the control condition, never both. Additionally, training data often contains uncertainty, particularly when target variables are interval-valued, such as in the presence of censored observations. To address these challenges, existing treatment effect estimation models are analyzed, and novel attention-based approaches that explicitly account for training data uncertainty are introduced.
