Abstract: A method including obtaining image data and attribute information of a first item in an item catalog. The method also can include generating candidate variant items from the item catalog for the first item using a combination of (a) a k-nearest neighbors approach to search for first candidate variant items based on text embeddings for the attribute information of the first item, and (b) an elastic search approach to search for second candidate variant items based on image embeddings for the image data of the first item. The method additionally can include performing respective classifications based on respective pairs comprising the first item and each of the candidate variant items to filter the candidate variant items. The method further can include determining a respective distance between the first item and each of the candidate variant items, as filtered.

Abstract: A method, system and computer-readable storage medium for transferring data segments from one computer system to a second computing system. Prior to transfer of the data segments, the first system calculates compressibility ratio of each segment and compares the compressibility ratio to a preset threshold. Based on the comparison, the first system assigns a compressibility hint to each segment. The first system transfers the segments to the second system, together with the corresponding compressibility hint. The second system stores each segment in a compressible region or in a non-compressible region based on the hint. Then the second system compresses the compressible region and stores the compressed region in a container, and stores the non-compressible region uncompressed in the container.

Abstract: Systems and methods are disclosed to implement a bounded group by query system that computes approximate time-sliced statistics for groups of records in a dataset according to a group by query. In embodiments, a single pass scan of the dataset is performed to accumulate exact results for a maximum number of groups in a result grouping structure (RGS) and approximate results for additional groups in an approximate result grouping structure (ARGS). RGSs and ARGSs are accumulated by a set of accumulator nodes and provided to an aggregator node, which combines the received structures to generate exact or approximate statistical results for at least a subset of the groups in the dataset. Advantageously, the disclosed query system is able to produce approximate results for at least some of the groups in a single pass of the dataset using size-bounded data structures, without predetermining the actual number of groups in the dataset.

Abstract: The present invention relates to a system and a method for updating data models. Input data received from a data source and/or prediction data obtained from a data model is reduced based on baseline reference data to obtain a plurality of representative points. The plurality of representative points are clustered to generate a plurality of clusters. An outlier cluster is detected from the plurality of clusters based on a maximum distance of the plurality of clusters from a highest density cluster and/or comparison of quantity and values of the plurality of representative points with predefined rules. Data drift is identified based on changes in densities of the plurality of clusters. The data model is updated using information corresponding to the outlier cluster and the data drift.

Responsive to determining that the adjacent content items are not the prohibited classification, the target content item is placed in the slot, and the content feed including the target content item is sent for display to a viewing user.

Abstract: During a backup a procedure, a first storage entity may backup a set of database logs from a second storage entity and metadata associated with the set of database logs may be stored in a log deletion table. In accordance with a user configuration of the second storage entity and the backup procedure, a first command to delete one or more database logs of the set from the second storage entity may be transmitted to the second storage entity. The log deletion table may be updated based on a query of second storage entity about whether the one or more database logs were deleted from the second storage entity in response to the first command. Based on the updated log deletion table, a second command may be transmitted to the second storage entity to delete database logs that were not deleted in response to the first command.
