11. One or more non-transitory computer-readable storage media including instructions that, when executed by at least one processor, cause the at least one processor to perform steps for curating content items, the steps comprising:

generating, for each content item included in a plurality of content items, a representation of the content item, wherein the representation of the content item comprises a first plurality of weights associating the content item with a plurality of content item groups;

generating a representation of a user that comprises a second plurality of weights associating the user with the plurality of content item groups, wherein each weight included in the second plurality of weights corresponds to a different content item group in the plurality of content item groups and is computed based on combining (i) one or more of the representations of content items that belong to the corresponding content item group and that are associated with one or more first content items that the user has at least one of purchased or engaged with, and (ii) one or more time decays that are computed based on when the user at least one of purchased or engaged with the one or more first content items;

generating one or more lists of content items based on the representation of the user; and

causing the one or more lists of content items to be displayed to the user.

12. The one or more non-transitory computer-readable storage media of claim 11 , wherein generating the one or more lists of content items comprises:

selecting one or more content item groups based on the representation of the user and a threshold for the first plurality of weights included in the representation of the user; and

generating a first set of lists of content items, wherein each list included in the first set of lists comprises one or more second content items from a content item group included in the one or more content item groups, and wherein the one or more second content items have been at least one of purchased or engaged with by the user.

13. The one or more non-transitory computer-readable storage media of claim 12 , wherein generating the one or more lists of content items further comprises generating a second set of lists of content items, wherein each list included in the second set of lists comprises one or more third content items from a content item group that is not included in the one or more content item groups.

14. The one or more non-transitory computer-readable storage media of claim 12 , wherein generating the one or more lists of content items further comprises generating a second set of lists of content items, wherein each list included in the second set of lists comprises one or more third content items that have not been purchased or engaged with by the user.

15. The one or more non-transitory computer-readable storage media of claim 12 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to perform steps comprising:

for each list included in the first set of lists, removing content items included in the list that are also included in at least a threshold number of previous lists in the ordering of the first set of lists, wherein the threshold number is based on a size of a smallest list included in the one or more previous lists.

16. The one or more non-transitory computer-readable storage media of claim 15 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to perform steps comprising determining the threshold number of previous lists as a multiple of the size of the smallest list.
