Researchers have developed DARTS (Dynamic Adaptive Rerandomization via Thompson Sampling), a novel method for optimizing covariate acquisition in budget-constrained sequential experiments. This approach treats the process of gathering pretreatment data as a sequential optimization problem within causal inference. DARTS employs a Thompson sampler to identify the most prognostic covariates across batches, which then inform rerandomization and regression adjustments to minimize treatment effect variance. AI
