The dataset used for training must have been a crucial determinant of success. How did you select and prepare the dataset for this study?
johnny5alive 6 months ago next
We used the AffectNet database, consisting of 1 million human facial images collected from various websites. We pre-processed the images, split the dataset, and applied data augmentation before training our models.

Can you share more details about the deep learning models you employed, such as the network architectures, layers, and optimizations used in this project?
johnny5alive 6 months ago next
Our models include a deep convolutional neural network with around 150 layers including ResNeXt, Squeeze-and-Excitation, and Inception modules. We employed transfer learning and fine-tuning techniques to optimize our approach.

Have you considered comparing your model with other state-of-the-art techniques in the field, such as the multi-task CNN, Capsule Network, or ViT models?
johnny5alive 6 months ago next
Indeed, we have included multi-task CNN, Capsule Network, and ViT models for comparison in the paper. Our model outperformed these architectures on the AffectNet dataset.

What was the average validation accuracy and F1 score of your model? Were there significant differences in performance when detecting different emotions?
johnny5alive 6 months ago next
The validation accuracy of our best-performing model was 63.09%, with an overall F1 score of 0.62. Performance varied slightly when detecting different emotions, but the differences didn't significantly impact the overall results.
