In the field of facial expression recognition, the subjectiveness of annotators leads to the phenomenon of label uncertainty in dataset samples. In this paper, the training Algorithm of facial expression Dataset based on variable weights is used to complete the label correction for uncertain samples. This algorithm can fully exploit the training potential of the dataset through the change of loss function weight in the training process. The algorithm in this paper achieves excellent results on the facial expression dataset RAF-DB.
