Action Steps
  1. Apply active feature acquisition (AFA) to improve model performance on test instances
  2. Use in-context learning to adaptively select features to acquire
  3. Configure AFA methods to learn from retrospective data with systematic missingness
  4. Test the performance of AFA methods on multiple tasks to evaluate scalability
  5. Compare the results of different AFA methods to determine the most effective approach

Title: Learning-To-Measure: In-Context Active Feature Acquisition

Abstract:
arXiv:2510.12624v2 Announce Type: replace-cross Abstract: Active feature acquisition (AFA) is a sequential decision-making problem where the goal is to improve model performance for test instances by adaptively selecting which features to acquire. In practice, AFA methods often learn from retrospective data with systematic missingness in the features and limited task-specific labels. Most prior work addresses acquisition for a single predetermined task, limiting scalability. To address this limi
