Latest Patents

Sun's latest patents include a system for allocating shoppers for order fulfillment by an online concierge system. This system accounts for variable numbers of shoppers across different time windows and varying capabilities for fulfilling orders. The online concierge system maintains a data store with discrete time intervals for fulfilling orders and information on shoppers categorized in a tree structure based on their characteristics. When an order is received, the system employs a machine learning model trained on historical data to estimate the number of available shoppers and their corresponding levels in the tree structure. Orders are tagged based on their contents, and these tags are matched to the levels of capable shoppers. Shoppers are grouped and scored based on their levels, leading to the selection of a group with the minimum score and capability to fulfill the order. This approach ensures efficient and timely fulfillment.

Another patent by Sun involves an online concierge system that allows users to order items within discrete time intervals later than when the order was received. Each order may require different characteristics for fulfillment by shoppers. The system maintains hierarchical structures for different shopper characteristics, with each level having a value. To select a shopper for an order, the system identifies groups of shoppers with the necessary characteristics and scores them based on their levels in the hierarchical structure. A shopper from the group with the minimum score is then selected to fulfill the order.
