Electronic device for generating user-preferred content, and operating method therefor

An electronic device comprising:

• a memory storing one or more instructions;
• and
• a processor configured to execute the one or more instructions stored in the memory to:
• obtain first content including at least one of an image or audio,
• detect at least one feature to be used to change a style of the first content, by applying the first content to a feature detection model,
• apply the first content and the at least one feature to a neural style transfer (NST) model, wherein the NST model is trained to generate a second content based on the first content and the at least one feature applied to the NST model by changing the style of the first content, and the second content includes an image audio pair in which an image or audio is determined by the NST model, and
• output the second content,
• wherein the NST model includes:
• a first sub-network configured to change a style of an image and a second sub-network configured to change a style of audio, and
• at least some layers of the first sub-network are connected to at least some layers of the second sub-network, for weight sharing between the first sub-network and the second sub-network.
