Causal Intervention
Overview
It asks what would happen if a variable or mechanism were deliberately changed, rather than merely observed, to estimate effects, test explanations, or choose actions. Common approaches include structural causal models and the do-calculus, randomized or targeted experiments, hard- and soft-intervention causal discovery, and counterfactual or Bayesian optimization methods that select interventions under costs. Applications range from gene perturbation and clinical policies to dynamical systems, robot control, and audits of neural-network features, evaluated with synthetic ground truth and real experimental or time-series data. Key challenges include limited or unknown intervention targets, hidden confounding and feedback, and whether conclusions transfer across environments; observational fit alone often cannot establish what an intervention will do.
