Abstract: Devices and techniques are generally described for ranking of search results based on multiple objectives. A first ranking for a plurality of search results is determined using a first machine learning model optimized for a first objective for ranking search results. A second objective for ranking search results is determined. A constraint is determined for the at least one second objective. The first machine learning model is iteratively updated to generate an updated machine learning model by minimizing a cost of the first objective subject to the constraint, wherein violations of the constraint are penalized using a penalty term. A second ranking for the plurality of search results is determined using the updated machine learning model. The search results of the second ranking are reordered relative to the search results of the first ranking.

Abstract: Systems and techniques are generally described for determining similar content. First embedding data may be generated for first content based at least in part on a specified similarity task. A first query comprising the first embedding data may be generated and sent to a first database partition. A first search result representing second content may be determined using the first embedding data. A second query comprising the first embedding data may be generated and sent to a second database partition different from the first data base partition. A second search result representing third content may be determined using the first embedding data. In some examples, output data comprising at least one of the first search result and the second search result may be generated. The output data may represent content classified as similar to the first content.

Abstract: Devices and techniques are generally described for regionalizing content based on the availability of similar content. In some examples, a first search query related to a first item may be received. A determination may be made that the first search query is associated with a first region. In some examples, the first item may be determined to be associated with the first region based at least in part on at least one of the first item or items classified as substitutes for the first item being available in a plurality of regions. A first plurality of search results associated with the first region may be determined. In further examples, code may be generated to cause the first computing device to display the first plurality of search results.
