Systems and methods for selecting content using a multiple objective, multi-arm bandit model

A first electronic device associated with a media-providing service, comprising:

• one or more processors;
• and
• memory storing instructions for execution by the one or more processors, the instructions including instructions for:
• for a first session of a user:
• for each of a plurality of lists of media content items, determining a respective value for each objective of a first set of objectives and a second set of objectives by accessing contextual data for the first session of the user, wherein the first set of objectives corresponds to the user and the second set of objectives corresponds to a second party distinct from the user;
• using a multi-arm bandit model, identifying a first list of media content items, from the plurality of lists of media content items, to present to the user, including:
• calculating a score for each list in the plurality of lists of media items using the respective value for each objective of the first set of objectives and the second set of objectives;
• probabilistically selecting the first list of media content items according to the respective scores corresponding to the respective lists in the plurality of lists of media items;
• and
• updating a user interface of a second electronic device, associated with the user, to present the first list of media content items to the user.
