Localized exploration in contextual dynamic pricing achieves dimension-free regret
Jinhang Chai, Yaqi Duan, Jianqing Fan +1
We study the problem of contextual dynamic pricing with a linear demand model. We propose a novel localized exploration-then-commit (LetC) algorithm which starts with a pure explor…
Adaptive and Robust Multi-Task Learning
Yaqi Duan, Kaizheng Wang
We study the multi-task learning problem that aims to simultaneously analyze multiple datasets collected from different sources and learn one model for each of them. We propose a f…
Communication-Efficient Accurate Statistical Estimation
Jianqing Fan, Yongyi Guo, Kaizheng Wang
When the data are stored in a distributed manner, direct application of traditional statistical inference procedures is often prohibitive due to communication cost and privacy conc…
