Quantum Communication Lower Bounds for Search Problems via Matrix Discrepancy

Minbo Gao, Chenghua Liu, Guangxu Yang +1

We study one-way quantum communication lower bounds for search problems. Unlike decision problems, search problems can have many valid outputs, which pose a fundamental barrier to…

Exponential Separation of Quantum and Classical One-Way Numbers-on-Forehead Communication

Guangxu Yang, Jiapeng Zhang

Numbers-on-Forehead (NOF) communication model is a central model in communication complexity. As a restricted variant, one-way NOF model is of particular interest. Establishing str…

PASTO: Strategic Parameter Optimization in Recommendation Systems -- Probabilistic is Better than Deterministic

Weicong Ding, Hanlin Tang, Jingshuo Feng +17

Real-world recommendation systems often consist of two phases. In the first phase, multiple predictive models produce the probability of different immediate user actions. In the se…
