OneShot: Index-in-Ranking with Neural Scoring for Large-Scale Retrieval
Ziwei Li, Shuyao Li, Xufeng Cai +12
The paper introduces OneShot, an end-to-end framework that jointly learns an index and ranking model for large‑scale retrieval, aligning index structure with ranking objectives and…
Adaptive Delayed-Update Cyclic Algorithm for Variational Inequalities
Yi Wei, Xufeng Cai, Jelena Diakonikolas
Cyclic block coordinate methods are a fundamental class of first-order algorithms, widely used in practice for their simplicity and strong empirical performance. Yet, their theoret…
Near-Linear Runtime for a Classical Matrix Preconditioning Algorithm
Xufeng Cai, Jason M. Altschuler, Jelena Diakonikolas
In 1960, Osborne proposed a simple iterative algorithm for matrix balancing with outstanding numerical performance. Today, it is the default preconditioning procedure before eigenv…
HyperZero: A Customized End-to-End Auto-Tuning System for Recommendation with Hourly Feedback
Xufeng Cai, Ziwei Guan, Lei Yuan +11
Modern recommendation systems can be broadly divided into two key stages: the ranking stage, where the system predicts various user engagements (e.g., click-through rate, like rate…
