Cost Aware Feature Elicitation

Motivated by clinical tasks where acquiring certain features such as FMRI or blood tests can be expensive, we address the problem of test-time elicitation of features. We formulate the problem of costaware feature elicitation as an optimization problem with trade-off between performance and feature acquisition cost. Our experiments on three real-world medical tasks demonstrate the efficacy and effectiveness of our proposed approach in minimizing costs and maximizing performance.
