    Learning-to-Defer with Expert-Conditional Advice

    Researchers have developed new methods for 'Learning-to-Defer' (L2D) systems, which decide whether to make a prediction or consult an expert. The latest advancements address limitations in existing frameworks by allowing systems to not only select an expert but also to provide that expert with additional, context-specific information. New approaches also extend L2D to utilize multiple experts simultaneously, enabling systems to query the top-k most cost-effective entities or adapt the number of experts based on input difficulty. AI

    IMPACT These advancements in Learning-to-Defer could lead to more efficient and accurate AI systems by optimizing expert consultation and enabling collaborative intelligence.

    Density-Ratio Losses for Post-Hoc Learning to Defer

    Researchers have introduced a novel post-hoc Learning to Defer (L2D) framework that reframes the problem through the lens of ideal distributions. This approach defines deferral by calculating the density-ratio between a model's and an expert's ideal distributions. The derived DR CPE losses allow for adjustable deferral rates without the need for retraining, and experimental results show competitive performance and robustness across various datasets. AI
