    Abstract: An online concierge system includes a content selection simulation module that performs offline simulations of a content selection process to enable rapid testing of various content selection parameters. The content selection simulation module obtains historical content selection data including content delivery opportunities and candidate content items associated with those content delivery opportunities. The content selection simulation module simulates the filtering, ranking, and auction stages of a content selection process using a set of configurable content selection parameters that affects selection of a winning content item and price. The winning content items from the simulation may be used to compute performance metrics associated with the configured content selection parameters. Different content selection parameters may be compared to determine an effect of changes to the parameters.

    Abstract: The present disclosure is directed to determining purchase suggestions for an online shopping concierge platform. In particular, the methods and systems of the present disclosure may receive, from a computing device associated with a customer of an online shopping concierge platform, data indicating one or more interactions of the customer with the online shopping concierge platform; determine, based at least in part on one or more machine learning (ML) models and the data indicating the interaction(s), a likelihood that the customer will purchase a particular item if presented, at a specific time, with a suggestion to purchase the particular item; and generate and communicate data describing a graphical user interface (GUI) comprising at least a portion of a listing of one or more purchase suggestions including the suggestion to purchase the particular item.

    Abstract: Embodiments are related to using a trained computer model to predict a supply state of an online system for state-aware management of order fulfillments. The online system measures first values of a metric for a set of sample orders. The online system accesses the computer model trained to predict a value of the metric for an order placed with the online system. The online system applies the computer model to predict second values of the metric for the set of sample orders, based on one or more features of each sample order. The online system compares a distribution of the first values to a distribution of the second values and determines the supply state of the online system based on the comparison. Responsive to the determination of the supply state, the online system triggers a remedial action for the online system that adjusts the supply state of the online system.

    Abstract: An online concierge system receives information describing items in orders placed by a customer and a sequence of events associated with each order and identifies an impulse item included in the orders based on a set of rules, attributes of each item, and/or the sequence of events. The system applies a model to predict a measure of similarity between the impulse item and each of multiple candidate items and identifies larger-size variants of the impulse item based on this prediction and attributes of the impulse item and each candidate item. The system applies another model to predict a likelihood the customer will order each variant, computes a recommendation score for each variant based on this prediction, and determines whether to recommend each variant based on the score. Based on the determination, the system generates and sends a recommendation for a variant to a client device associated with the customer.

    Abstract: Embodiments relate to an automatic detection of fraudulent behavior for a transaction at an online system. The online system requests a large language model (LLM) to determine, based on a prompt input into the LLM, information about a refund event for a first order placed by a user of the online system. The online system accesses a computer model trained to detect a fraudulent behavior associated with an order placed with the online system. The online system applies the computer model to determine a score associated with the refund event, based on the information about the refund event received from the LLM. The online system determines, based on the score, whether the refund event was due to a fraudulent behavior of the user. The online system performs at least one action associated with the online system, based on the determination whether the refund event was due to the fraudulent behavior.

    Abstract: An online concierge system uses a machine-learned parking quality model to quantify the suitability of a particular parking location (e.g., a parking lot, or a street) for use when performing purchases at a retail location on behalf of customers. The parking quality model's output is determined according to input features related to parking at a candidate parking location, such as a current time, a current degree of demand for shoppers at the retail location, or a current average shopper wait time at the retail location before receiving an order. The online concierge system provides suggested alternate parking locations to a client device of the shopper, where they may be displayed, e.g., as part of an electronic map. Use of the suggested alternate parking locations helps to preserve parking availability in restricted areas such as retailer parking lots and to reduce traffic congestion in the area of the retailer.
