Statistical Learning Theory for Direct Preference Optimization

Direct Preference Optimization (DPO) learns from pairwise preferences through a logistic objective whose score-difference parameterization follows the Bradley--Terry model. We study how failure of this modeling assumption limits DPO, distinguishing structural misspecification from limited model capacity and finite-samp...

Stability and Generalization of Straight-Through Estimators for Training Two-Layer Quantized Neural Networks

An exact distance identity for two coupled updates is derived and approximate non-expansiveness of the common-example map is proved, with a quadratic defect only when the two latent margins straddle zero.
