 - **FacialModel-8177.h5**: This model was developed as an ensemble combining convolutional neural networks, the VGG19 model, and Keras Tuner techniques. It was trained using two widely recognized datasets in the field of emotion recognition: FER2013 and CK+48. To address class imbalance, two complementary strategies were applied: (1) the use of weighted classes to adjust the importance of each class based on its representation, and (2) the generation of synthetic data through data augmentation techniques, which improved the distribution of emotions and the model’s generalization.
