Abstract: An online system displays an interface to users including slots in which sources from a list of sources of items (e.g., physical items, content items) are presented. The user may select a source via the interface to view items provided by, or associated with, the source. To simplify a user identifying a desired source, the online system includes sources that a user is likely to select as well as new sources in the list. To balance the competing interests of relevance of sources with which the user previously interacted and discovery of new sources, the online system selects an allocation of slots for new sources and for sources with prior interaction based on interactions by users in the geographic regions with different allocations of slots. Based on the selected allocation of slots, the online system selects specific retailers for each slot using ranking models corresponding to different slots.

Abstract: In various examples, query-based evaluation of error patterns in annotated training data for machine learning systems and applications is provided. An error pattern evaluator may include an error pattern extraction function and an error pattern search algorithm. An annotated validation sample associated with an inaccurate prediction from a machine learning model may be analyzed to extract an error pattern. A set of annotated training data used for training the machine learning model may be analyzed by the error pattern extraction function to generate an error pattern for individual samples of annotated training data to define a search dataset. An error pattern search algorithm may use the error pattern derived from the inaccurate prediction as a query to search the dataset to identify each occurrence of samples having an error pattern similar to the query error pattern. The set of annotated training data may be corrected based on the search results.

The online system identifies training label-name pairs from a plurality of orders including a set of item names and associated receipt labels, wherein the training label-name pairs are optimized based on fuzzy matching and/or statistical association scores. The online system fine-tunes the language model to perform tasks for translating between receipt labels and item names or scoring receipt labels and item pairs based on statistical association.

Abstract: A ranking computer model is trained based on grouping a collection of users of an online system into different buckets based on intended likelihoods of presenting a set of content items to the collection of users, wherein a contextual bandit model is employed to compute the intended likelihoods. The online system applies the ranking computer model to generate, based on user data for a user of the online system and contextual data associated with a current session of the user, a ranking score for each content item in a set of content items. The online system selects, based on the ranking score for each content item, one or more content items from the set of content items. The online system causes a device associated with the user to display a user interface with the one or more content items for recommendation to the user.

Abstract: A messaging tool is executed to conduct and analyze a real-time conversation between, at least, one user and another user. The messaging tool includes at least one artificial intelligence model generated and integrated into the messaging tool. The at least one artificial intelligence model is generated based on analyzing historical data including data related to, at least, one or more historical risk-based events. The at least one artificial intelligence model is trained to categorize analysis data resulting from the analyzing the historical data and to predict a risk-based event. Real-time analysis is performed of the real-time conversation to generate a probability score. The probability score indicates a prediction that the real-time conversation is the risk-based event. The risk-based event is visualized to indicate to a selected user that the real-time conversation is the risk-based event. The selected user is a user of the real-time conversation.
