Online Planning of Power Flows for Power Systems Against Bushfires Using Spatial Context

no code implementations20 Apr 2024 Jianyu Xu, Qiuzhuang Sun, Yang Yang, Huadong Mo, Daoyi Dong

Our model assumptions are verified by the real bushfire data from NSW, Australia, and we apply our model to two power systems to illustrate its applicability.

Pricing with Contextual Elasticity and Heteroscedastic Valuation

no code implementations26 Dec 2023 Jianyu Xu, Yu-Xiang Wang

We study an online contextual dynamic pricing problem, where customers decide whether to purchase a product based on its features and price.

TheoremQA: A Theorem-driven Question Answering dataset

1 code implementation21 May 2023 Wenhu Chen, Ming Yin, Max Ku, Pan Lu, Yixin Wan, Xueguang Ma, Jianyu Xu, Xinyi Wang, Tony Xia

We evaluate a wide spectrum of 16 large language and code models with different prompting strategies like Chain-of-Thoughts and Program-of-Thoughts.

Doubly Fair Dynamic Pricing

no code implementations23 Sep 2022 Jianyu Xu, Dan Qiao, Yu-Xiang Wang

We show that a doubly fair policy must be random to have higher revenue than the best trivial policy that assigns the same price to different groups.

Towards Agnostic Feature-based Dynamic Pricing: Linear Policies vs Linear Valuation with Unknown Noise

no code implementations27 Jan 2022 Jianyu Xu, Yu-Xiang Wang

In feature-based dynamic pricing, a seller sets appropriate prices for a sequence of products (described by feature vectors) on the fly by learning from the binary outcomes of previous sales sessions ("Sold" if valuation $\geq$ price, and "Not Sold" otherwise).

Logarithmic Regret in Feature-based Dynamic Pricing

no code implementations NeurIPS 2021 Jianyu Xu, Yu-Xiang Wang

Feature-based dynamic pricing is an increasingly popular model of setting prices for highly differentiated products with applications in digital marketing, online sales, real estate and so on.
