Systems and methods for generating multidimensional data structures based on fantasy sports account activity

A system for generating a multidimensional data structure using fantasy sports account activity, comprising:

• one or more processors;
• and
• memory comprising;
• computer-readable instructions stored in memory that, when executed by the one or more processors, cause the one or more processors to:
• maintain a plurality of user profiles, each of the user profiles having one or more player lineups associated with at least one fantasy sports contest;
• identify, for a first user profile of the plurality of user profiles, one or more player lineups of the first user profile and one or more respective contests for which the player lineups were entered, each of the player lineups including a plurality of players, each of the plurality of players having one or more players attributes, each of the contests having one or more contest attributes;
• generate, for the first user profile, a multidimensional data structure including a plurality of features, each feature having a respective value that is based on the player attributes corresponding to the players included in the one or more player lineups and the contest attributes corresponding to the one or more respective contests for which the player lineups were entered;
• select, using the multidimensional data structure, content for presentation to a device associated with the user profile, the content selected using an association between at least one player attribute and at least one contest attribute identified by the multidimensional data structure;
• and
• provide, using the generated multidimensional data structure, the content to the device associated with the user profile.
