Existing _Learning-to-Defer_ (L2D) frameworks are limited to _single-expert deferral_, forcing each query to rely on only one expert and preventing the use of collective expertise. We introduce the first framework for _Top-$k$ Learning-to-Defer_, which allocates queries to the $k$ most cost-effectiv…
The Two-Stage Learning-to-Defer (L2D) framework has been extensively studied for classification and, more recently, regression tasks. However, many real-world applications require solving both tasks jointly in a multi-task setting. We introduce a novel Two-Stage L2D framework for multi-task learning…
Two-stage Learning-to-Defer (L2D) enables optimal task delegation by assigning each input to either a fixed main model or one of several offline experts, supporting reliable decision-making in complex, multi-agent environments. However, existing L2D frameworks assume clean inputs and are vulnerable…
