Expert imbalance can cripple learning-to-defer systems, but a novel cost-sensitive margin-based loss function can restore performance.
Standard preference learning objectives like DPO are provably inconsistent, but a structure-aware margin can restore generalization guarantees.
Get the best of both worlds: Linear-Core Surrogates offer the fast optimization of smooth losses and the statistical efficiency of margin-based losses, without sacrificing differentiability.
