Ad-Corre: Adaptive Correlation-Based Loss for Facial Expression Recognition in the Wild

1 code implementation IEEE Access 2022 Ali Pourramezan Fard, Mohammad H. Mahoor

In addition, the Mean Discriminator component leads the network to make the mean embedded feature vectors of different classes to be less similar to each other. We use Xception network as the backbone of our model, and contrary to previous work, we propose an embedding feature space that contains k feature vectors.
