OBJECT INFORMATION PROCESSING METHOD AND APPARATUS, DEVICE AND MEDIUM

The present application relates to an object information processing method, comprising: acquiring a sample set, the sample set comprising sample object information, and the sample object information corresponding to a label (202); acquiring a label similarity of the labels corresponding to any two pieces of sample object information in the sample set, acquiring a hash similarity between hash codes generated by a hash generation model to be trained for said any two pieces of sample object information, and determining a difference between the label similarity and the hash similarity, to obtain a first loss value on the basis of the difference (204); for each piece of sample object information in the sample set, determining a first hash similarity between said sample object information and similar sample object information in the sample set, the similar sample object information being sample object information in the sample set similar to said sample object information (206); determining a second hash similarity
