Boosting Gradient Ascent for Continuous DR-submodular Maximization

no code implementations16 Jan 2024 Qixin Zhang, Zongqi Wan, Zengde Deng, Zaiyi Chen, Xiaoming Sun, Jialin Zhang, Yu Yang

The fundamental idea of our boosting technique is to exploit non-oblivious search to derive a novel auxiliary function $F$, whose stationary points are excellent approximations to the global maximum of the original DR-submodular objective $f$.

Communication-Efficient Decentralized Online Continuous DR-Submodular Maximization

no code implementations18 Aug 2022 Qixin Zhang, Zengde Deng, Xiangru Jian, Zaiyi Chen, Haoyuan Hu, Yu Yang

Maximizing a monotone submodular function is a fundamental task in machine learning, economics, and statistics.

Online Learning for Non-monotone Submodular Maximization: From Full Information to Bandit Feedback

no code implementations16 Aug 2022 Qixin Zhang, Zengde Deng, Zaiyi Chen, Kuangqi Zhou, Haoyuan Hu, Yu Yang

In this paper, we revisit the online non-monotone continuous DR-submodular maximization problem over a down-closed convex set, which finds wide real-world applications in the domain of machine learning, economics, and operations research.

MNL-Bandits under Inventory and Limited Switches Constraints

no code implementations22 Apr 2022 Hongbin Zhang, Yu Yang, Feng Wu, Qixin Zhang

Optimizing the assortment of products to display to customers is a key to increasing revenue for both offline and online retailers.

Stochastic Continuous Submodular Maximization: Boosting via Non-oblivious Function

no code implementations3 Jan 2022 Qixin Zhang, Zengde Deng, Zaiyi Chen, Haoyuan Hu, Yu Yang

In the online setting, for the first time we consider the adversarial delays for stochastic gradient feedback, under which we propose a boosting online gradient algorithm with the same non-oblivious function $F$.

Online Allocation Problem with Two-sided Resource Constraints

no code implementations28 Dec 2021 Qixin Zhang, Wenbing Ye, Zaiyi Chen, Haoyuan Hu, Enhong Chen, Yang Yu

As a result, only limited violations of constraints or pessimistic competitive bounds could be guaranteed.
