Assignee: SICHUAN UNIVERSITY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. The face recognition method according to claim 4, wherein the step of calculating the accuracy rate in step B5 comprises:
selecting predicted probabilities of each face output by the first individual,
selecting a classification with a highest probability as a predicted classification, and
determining whether the predicted classification is identical to a real classification of face image subdata corresponding to the predicted classification,
when the predicted classification is identical to the real classification, recording a predicted result as 1,
when the predicted classification is not identical to the real classification, recording the predicted result as 0; wherein
the accuracy rate is obtained according to the predicted result of the first individual on the face image subdata in the validation set; the accuracy rate P is specifically calculated as:, P
   =
   
    n
    m
   
  
  ,
 

where, n represents a number of correct prediction made by the first individual on the real classification of the face image subdata in the validation set, and m represents a total number of the face image subdata in the validation set.
