Researchers have developed a new framework called LEC (Linear Expectation Constraints) to improve the reliability of foundation models in selective prediction tasks. LEC reframes selective prediction as a decision problem, directly controlling the marginal error probability conditioned on user selection. This approach ensures that accepted predictions have an error probability no larger than a specified risk level, outperforming existing methods in sample retention for question answering and vision question answering tasks. The framework is also extended to two-model routing systems, maintaining system-level error control when delegating to a secondary model. AI
