Information processing apparatus, information processing method, and non-transitory recording medium

An information processing method that is executed by at least one computer, the information processing method comprising:

• generating a patch token and a prefix token corresponding to an input image;
• extending the prefix token to a prefix token block having a size corresponding to a number of a plurality of patch token blocks into which the patch token is segmented in accordance with a predetermined grid pattern;
• and
• performing an arithmetic operation on the prefix token block and the patch token blocks, on the basis of a self-attention mechanism, for each group of elements located at a common position in the respective blocks.

A non-transitory recording medium on which a computer program that allows at least one computer to execute an information processing method is recorded, the information processing method including:

• generating a patch token and a prefix token corresponding to an input image;
• extending the prefix token to a prefix token block having a size corresponding to a number of a plurality of patch token blocks into which the patch token is segmented in accordance with a predetermined grid pattern;
• and
• performing an arithmetic operation on the prefix token block and the patch token blocks, on the basis of a self-attention mechanism, for each group of elements located at a common position in the respective blocks.
