Image encoding learning and application

An electronic device, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions executable by the at least one processing unit, the instructions, upon execution by the at least one processing unit, causing the device to perform acts comprising:
• extracting an image feature representation of a sample image using an image encoder to be trained;
• extracting a text feature representation of a sample text sequence using a text encoder, the sample text sequency being associated with the sample image;
• generating, using the text encoder, a predicted text sequence based on the text feature representation and the image feature representation;
• and
• training the image encoder at least based on a text error between the predicted text sequence and the sample text sequence.

A non-transitory computer-readable storage medium, having a computer program stored thereon which, upon execution by a processor, implements acts comprising:

• extracting an image feature representation of a sample image using an image encoder to be trained;
• extracting a text feature representation of a sample text sequence using a text encoder, the sample text sequency being associated with the sample image;
• generating, using the text encoder, a predicted text sequence based on the text feature representation and the image feature representation;
• and
• training the image encoder at least based on a text error between the predicted text sequence and the sample text sequence.
