at least one processor configured to:

generate a training set based on the plurality of taste profiles and the plurality of media item vectors;

obtain a plurality of resulting codes corresponding to at least one of the plurality of media item vectors in the second domain;

generate a plurality of weighted term vectors based on the plurality of taste profiles;

generate vector quantized media data by vector quantizing the plurality of media item vectors; and

generate a map of the weighted term vectors to the vector quantized media data,
