An online system utilizes multi-agent language models for context-aware understanding of a query. The online system receives the query submitted by a user during a user's session at the online system, and stores, during the session, information about the session. The online system generates a prompt for input into the language models, the prompt including the query and the information about the session. Each language model is tuned to infer a respective type of context of the query and generate, based on the prompt, a response including information about the respective type of context. The online system generates, using responses from the language models, a query understanding string with information about types of context of the query. The online system uses the query understanding string to identify a set of items and displays a user interface with items so that the user can order one or more items.
An online system performs an inference task in conjunction with the model serving system and/or interface system to generate relevant product images for query auto-completion and query suggestion to help users better navigate their search experience. The online system generates a collection of query suggestions using search query log mining. For each query suggestion in the collection of query suggestions, the online system retrieves one or more catalog images that depict the query suggestion from a product catalog. The online system constructs a prompt to a text-to-image model including the query suggestion, and a request to generate one or more query images based on the query suggestion. The online system receives the query images from the text-to-image model and ranks the catalog and query images to identify an image to display to the user in association with the query suggestion.

A language model is used to generate autosuggestions to complete or revise a user's partial search query. An initial partial query is applied to the language model to generate query candidates for completing the search query. The language model may generate the query candidates as additional or alternate tokens for the partial search query. When the user revises the partial query, the previously-generated candidates can be re-used to reduce subsequent processing time for generating additional candidates. The previously-generated candidates are compared with the revised partial query to select which of the candidates to be re-used and expanded for generating additional tokens. Additional tokens can be generated in parallel for the previously-generated candidates or with model values from the previous generation, enabling the tokens to be generated effectively with reduced latency consistent with user expectations for search-related autosuggestions.

For example, the model generates a probability of a specific item being included in at least one recipe comprising a plurality of components. The model may be trained using users' inclusion of specific items previously selected for one or more groups of items based on collections of components by users of the online system.
An online system receives, at a search interface, a search term from a user. The system retrieves from a mapping table grouping parameters associated with the search term in the mapping table. The association between the grouping parameters and the search term in the mapping table is generated by generating a prompt including the search term and a set of physical objects that match the search term. The prompt requests grouping parameters for the set of physical objects, wherein each grouping parameter specifies a characteristic of the set of physical objects for providing search results responsive to the search term. The system receives, from the LLM, the grouping parameters and updates the mapping table. The system retrieves search results by querying a database of the online system using the search term. The system generates for display a user interface that groups the search results by the retrieved grouping parameters.

The method further includes generating a set of seed keywords related to the content item, and expanding the set of seed keywords to a plurality of candidate keywords. The plurality of candidate keywords are then scored based, at least in part, on an engagement metric measuring a user engagement with the content item in response to being presented with results from a search query comprising the candidate keyword. A candidate keyword is then selected from the plurality of candidate keywords based on the scoring, and stored relationally to the content item to define an audience for a recommendation about the content item, providing a suggestion to the content provider.
An online system that displays items from an item catalog to users supplements content displayed for one or more of the items with information extracted from images of the items. For a particular item in the item catalog, the online system performs image processing, such as optical character recognition, on one or more images of the item to extract text phrases from the images. For each extracted text phrase, the system then uses a trained model to score the text phrase as being a viable informational message. If the score for a text phrase is above a threshold, the online system augments content displayed in a user interface for the item with the text phrase. The online system may decide whether to supplement content for the item with an extracted text phrase based on the output of a predictive model.

A policy function may control one or more criteria in bidding content slots. The online system may monitor a realized outcome of the content presentation campaign. The online system may apply a reinforcement learning algorithm in adjusting the set of policy functions. The reinforcement learning algorithm adjusts one or more parameters in the set of policy functions to reduce a difference between the realized outcome and the desired outcome set by the content provider. The online system generates an adjusted set of policy functions and uses the adjusted set of policy functions in bidding content slots to present one or more content items provided by the content provider.
To evaluate the causal generalizability of multivariate regression models (such as marketing mix models) that evaluate a plurality of input features that may have high correlation and confounding causality, a model architecture is evaluated with respect to experimental data that varies feature values. The model architecture is trained with training data that excludes the experimental data. The trained model is then applied to predict the outcome of the experimental data inputs and the predicted outcome is scored with respect to the experimental outcome. This may be repeated across more than one experiment to evaluate how the model architecture generalizes to different types of variations in different experiments. The scores may then be used to validate the causal predictions and select or confirm a model architecture for use.

The online system manages rounds of messaging between the system Al agent and the user Al agent, and at some point, a proposed agreement between the user and online system is extracted from the messaging. The proposed agreement may then be presented to the user or online system for approval.
An online system receives orders from users and fulfills the orders by dispatching a picker to a physical source to obtain the items for delivery. Some items in an order may be considered “foundational,” meaning that a user who ordered the items may wish to cancel one or more other items in the order if the foundational item is unavailable (e.g., the item is a critical ingredient for a recipe). The online system predicts items in the order that are foundational using a trained machine-learning model. The online system presents the items to the picker in a sequence so the foundational items are obtained earlier by the picker. This enables the picker to observe whether the determined foundational item is available sooner in the picking process, allowing earlier performance of a remedial action and possibly avoiding replacing previously obtained items affected by the unavailability of the foundational item.
An online system uses a trained machine-learning model to detect errors in catalog data based on interactions of users of the online system with physical carts. Upon receiving an interaction signal indicating an interaction by the user with a device in a location of a source or an action signal indicating an action in the location of the source, the online system applies the trained model to the interaction signal and/or the action signal to generate an error score for an item that indicates a likelihood of an error in relation to the item. Responsive to the error score being above a threshold score, the online system generates an error checking signal for confirming that the error is present. Responsive to the confirmation of the error, the online system generates a user interface that alerts about the error and requests an action to correct the error.

The smart cart obtains, from an item database, a plurality of candidate content objects to be presented to a user of a smart cart. The smart cart obtains a location of the smart cart in an environment. The smart cart applies a machine-learning route prediction model to the location of the smart cart to determine a future route of the smart cart. The smart cart determines, for each candidate content object, one or more presentation constraints based on the future route of the smart cart, wherein the presentation constraints constrain presentation of the candidate content object to the user to maximize a likelihood of the user engaging with the content object. The smart cart presents, via an electronic display, one or more of the candidate content objects according to the presentation constraints.

GENERATING A SUGGESTED SHOPPING LIST BY POPULATING A TEMPLATE SHOPPING LIST OF ITEM CATEGORIES WITH ITEM TYPES AND QUANTITIES BASED ON A SET OF COLLECTION RULES
An online system generates a template shopping list for a user by accessing a machine learning model trained based on historical order information associated with the user, applying the model to predict likelihoods of conversion for item categories by the user, and populating the template shopping list with one or more item categories based on the predicted likelihoods. The system ranks one or more item types associated with each item category in the template shopping list and determines a set of collection rules associated with one or more item categories/types based on the historical order information. The system generates a suggested shopping list by populating each item category in the template shopping list with one or more item types and a quantity of each item type based on the ranking and rules and sends the suggested shopping list and rules for display to a client device associated with the user.
An online system may include a multi-agent code generator that receives webpage data describing a webpage with target content, identifies the target content by analyzing the structure of the webpage, and generates a script configured to extract the target content. The online system can execute the script to extract the target content and store the extracted data in a database for later access by the online system. For example, a chatbot of the online system can reference the stored data describing the target content to generate a response to a query.
An online system interfaces with an LLM to evaluate chatbot responses to user inputs in a conversation. The online system divides the conversation into portions and prompts the LLM to separately evaluate the chatbot's latest response in each portion. These conversation portions may include different amounts of the conversation and may build off of one another such that some portions include inputs/responses of other portions. To evaluate a chatbot's latest response in a portion, the online system may prompt the LLM to generate a score for the chatbot's response in the portion according to a conversation criterion. The prompt may instruct the LLM to consider the context of previous inputs/responses in that potion to generate the score. The online system reviews the scores and determines if any of the scores are below corresponding criteria thresholds. If so, the online system may perform a remedial action for the entire conversation.
A system and a method are disclosed for predicting future user engagement with a mobile device application based on a discrepancy detected between two physical objects. In an embodiment, a physical object provider receives, based on user input into the application, a request for delivery of a first physical object. A discrepancy is detected, the discrepancy reflecting that a second physical object is detected in place of the first physical object. A first set of features of the first physical object and a second set of features of the second physical object are inputted into a machine learning model. The machine learning model outputs a measure of predicted future engagement of the user with the application based on the discrepancy. The application is instructed to output an intervention based on the measure of predicted future engagement of the user.
A barcode decoding system decodes item identifiers from images of barcodes. The barcode decoding system receives an image of a barcode and rotates the image to a pre-determined orientation. The barcode decoding system also may segment the barcode image to emphasize the portions of the image that correspond to the barcode. The barcode decoding system generates a binary sequence representation of the item identifier encoded in the barcode by applying a barcode classifier model to the barcode image, and decodes the item identifier from the barcode based on the binary sequence representation.

An online system customizes documents for a particular context, user, or set of users. The online system receives an image of a physical document and extracts components, such as text, titles, items and their metadata, from the physical document. The online system may apply rules to the metadata for one or more items to determine whether to modify at least a portion of the metadata. The online system also applies a model to generate an affinity score for a context or a user and each component of the document. If the score for a component is below a threshold, the online system prompts a generative model to generate replacement content for the component. Subsequently, the online system applies the model to the generated replacement content and updates the document with the generated replacement content for the component if the score of the generated replacement content is higher.
An online concierge system generates the value for an impression by predicting future behavior by users beyond a current conversion. The predicted future behavior attributes incremental value of subsequent conversions by the user. The online concierge system gathers feature information about the user. Based on experimental data, the online concierge system generates a baseline curve describing expected user behavior for a category of users. Based on feature information of the user, the online concierge system applies a computer model to generate modifiers for the baseline curve to customize the baseline curve for the user. The modified curve is used to predict future actions by the user, and consequently a long-term incremental conversion value for the impression.
An online concierge system receives an order including one or more items from a customer and a picker obtains the items from a retailer. Upon completing obtaining items from the order and moving to checkout from the retailer, the picker updates an order status via a picker application. Via the picker application, the picker may capture an image of a shelf of items in the checkout line. The online concierge system identifies one or more items in the image using image processing and ranks the identified items for the customer from whom the order was received. The online concierge system includes a subset of the identified items ordered based on the ranking in a message to the customer via a communication interface between the customer and the picker. The message indicates the customer can add one or more of the identified items before the picker completes a checkout process.
An online concierge system selectively replaces default static item displays with dynamic item displays to represent items. The dynamic item displays encourage a viewing user of the online concierge system to purchase the items and may be selected based on item or user preferences or characteristics. The online concierge system applies a machine learning model to determine display scores describing the expected benefit of dynamic item displays and bandwidth scores describing resource usage of dynamic item displays. The online concierge system selectively replaces default static item displays with dynamic item displays based on the display and bandwidth scores so as to maximize benefit while ensuring that performance of the online concierge system is not negatively impacted by the resource usage.
A smart system, such as a smart shopping cart system, uses an efficient selection algorithm to select an item identifier prediction for an item. The smart cart system uses a set of machine-learning models to generate identifier predictions based on images. To select an item identifier, the smart system applies an efficient selection algorithm to the predictions from the machine-learning models. An efficient selection algorithm is an algorithm that requires minimal computational resources to perform. For example, the efficient selection algorithm may be a simple majority algorithm that selects the identifier prediction generated by a majority of the models or a weighted voting algorithm where each model's vote is weighted by some metric. The smart system applies the efficient selection algorithm to select an item identifier prediction from the ones generated by the models. The smart system may display content related to the item associated with the item identifier prediction.
An online system uses benchmarking tests to identify indexing algorithms for an embedding database. To perform these benchmarking tests, the online system receives a set of parameters for configuring an embedding database. For example, the parameters may include a performance parameter and a latency parameter. The online system generates algorithm scores for a set of candidate indexing algorithms based on the parameters. Specifically, the online system tests each of the candidate indexing algorithms by generating a testing database based on a subset of the entries for the full database and by performing benchmarking tests on the testing database. The online system uses these tests to compute performance metrics for each candidate indexing algorithm and uses those performance metrics to compute an algorithm score for each indexing algorithm. The online system uses the computed algorithm scores to select an indexing algorithm for the embedding database.
An online concierge system receives, from a client device associated with a user of the online concierge system, order data associated with an order placed with the online concierge system, in which the order data describes a delivery location for the order. The online concierge system receives information describing a set of attributes associated with the delivery location and accesses a machine learning model trained to predict a difference between an arrival time and a delivery time for the delivery location. The online concierge system applies the model to the set of attributes associated with the delivery location to predict the difference between the arrival time and the delivery time for the delivery location and determines an estimated delivery time for the order based at least in part on the predicted difference. The online concierge system sends the estimated delivery time for the order for display to the client device.
