One of Xu's latest patents is titled "User interface for presenting ranked surge pricing opportunities for pickers in an online concierge system." This invention addresses the challenge of scheduling pickers (shoppers) during peak demand periods. The system increases compensation for shoppers to encourage participation, thereby reducing missed orders. It utilizes predictive models of supply and demand to determine optimal compensation multipliers and applies an optimization algorithm to explore various hyperparameters affecting these models. Additionally, the system can present future multipliers and enable users to set reminder alerts for specific periods.

Another significant patent by Xu is "Detection and remediation of improper value modification using machine learning." This invention focuses on preventing unfair compensation reductions for pickers who fulfill orders. The online concierge system trains a model to assess the probability that a reduction in compensation is unrelated to fulfillment issues. Based on this probability, the system can take remedial actions to support pickers.
