An electronic device generates a score for each objective in a hierarchy of objectives. Generating the score comprises using a representation of the media content item and a user as inputs to a first machine learning algorithm, to generate a score for a first objective corresponding to a first level in the hierarchy of the objectives and using an output of the first machine learning algorithm, distinct from the score for the first objective, as an input to a second machine learning algorithm to generate a score for a second objective corresponding to a second level in the hierarchy of objectives. The electronic device generates a respective score between the user and the media content item using the score for the first objective and the score for the second objective and provides media content to the user based on the respective scores.
