Face recognition algorithm configuration based on unbalance tag information fusion

Abstract

The present invention discloses a face recognition algorithm configuration based on unbalance tag information fusion. The face recognition algorithm configuration comprises two layers of configurations (L1 and L2); the L1 is configured to train the face data and corresponding tag information to obtain an initial face recognition model 1 through adoption of a supervised learning algorithm, train no-tag data through adoption of an unsupervised method, alternately optimize the face data tag information and the parameters of the model 1, and obtaining a final face recognition model 1 through calculation after multiple iterations; the L2 has a thought opposite to the L1, the L2 is configured to initiate parameters of a face recognition model 2 at random, then perform unsupervised training to update the parameters of the model 2, input tag data, continuing training through adoption of the supervised learning algorithm, and finally obtaining the face recognition model 2; and the model 1 and the model 2 are fused to obtain a final face recognition model. Through combination of the advantages of a supervised learning algorithm and an unsupervised learning algorithm, the face recognition algorithm configuration based on unbalance tag information fusion gives full play to mass of no-tag data to allow the algorithm to have excellent recognition capability in a special scene and adapt different scenes.
