Providing content recommendations for user groups

A non-transitory machine-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• obtaining a first preference profile corresponding to a first user and a second preference profile corresponding to a second user;
• identifying a first content item based at least in part on the first preference profile and a second content item based at least in part on the second preference profile;
• identifying a first embedding corresponding to the first content item in an embedding space and a second embedding corresponding to the second content item in the embedding space, the embedding space comprising a plurality of embeddings corresponding to a plurality of different content items;
• generating an aggregate embedding based at least in part on an average of the first and second embeddings;
• determining a number of nearest neighbor embeddings in the embedding space with respect to the aggregate embedding;
• identifying a plurality of content items that correspond to the nearest neighbor embeddings;
• and
• providing, for display on a content output device, at least one indication of at least one of the plurality of content items as a recommendation to a user group that includes the first and second users.

A device comprising:

• a memory;
• and
• at least one processor configured to:
• obtain a user group preference profile that corresponds to a user group including a first user and a second user;
• identify a filter criteria for filtering a plurality of content items;
• determine a filter criteria value from the user group preference profile;
• search a first activity history of the first user and a second activity history of the second user for candidate content items that satisfy the filter criteria;
• obtain, based at least in part on the candidate content items, a plurality of content items that are related to the candidate content items;
• filter the plurality of content items based at least in part on the filter criteria value;
• and
• provide, for display to a user, an indication of at least one of the filtered plurality of content items.
