Adaptive clustering of media content from multiple different domains

A device, comprising:

• a processor;
• and
• a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• acquiring a plurality of data content items from a plurality of different domains, wherein at least some data content items of the plurality of data content items are unlabeled;
• encoding the plurality of data content items with a feature representing a domain shift variation that is assumed to be present in the plurality of data content items, wherein the domain shift variation comprises variation in a characteristic of the plurality of data content items;
• and
• clustering the plurality of data content items into a predefined number of content categories subsequent to the encoding.

A non-transitory computer-readable storage medium storing instructions which, when executed by a processor, cause the processor to perform operations, the operations comprising:
