Researchers have developed a new method for evaluating active feature acquisition policies using tabular foundation models. This approach addresses biases that arise from imbalanced offline data coverage, which can incorrectly penalize the acquisition of sparsely observed features. By targeting posterior expected entropy instead of total predictive entropy, the new method reduces value estimation bias and improves the selection of downstream policies, as demonstrated on synthetic and real-world datasets.
