Researchers have developed a new approach called MILD (Margin-based Imbalanced Learning to Defer) to address the expert imbalance problem in two-stage learning to defer systems. This method reframes deferral loss optimization as a cost-sensitive learning problem, leading to improved performance in scenarios where certain experts are favored due to data imbalance. The proposed algorithms and loss functions demonstrate effectiveness in both image classification and Large Language Model (LLM) routing tasks. AI
