摘要

There is provided a learning apparatus including: a first data acquisition unit which acquires first user preference data belonging to a first data space; a second data acquisition unit which acquires second user preference data of a user in common with the first user preference data, the second user preference data belonging to a second data space which is different from the first data space; a compression unit which generates first compressed user preference data having less data item number from the first user preference data by utilizing a first set of parameters; and a learning unit which learns a second set of parameters utilized for generating second compressed user preference data having the same data item number as that of the first compressed user preference data from the second user preference data so that difference between the first compressed user preference data and the second compressed user preference data is to be small across a plurality of users.
