摘要：Facial Expression Recognition (FER) is one of the most interesting problems in computer science due to its potential applications in AI, many studies were proposed for the FER, but it based on traditional machine learning techniques and these techniques do not have the generalizability to classify expressions from unseen images or those that are captured from the wild, so it is still a difficult and a complex problem. Recently, trends of research in various fields have begun to transfer to deep learning techniques, since it can learn and capture features automatically, robustness to natural variations in the data and generalizability. This work presents a comparative analysis of the popular convolutional neural network (CNN) models based on modular CNN architectures such as ResNet, DenseNet, MobileNet, NASNetMobile, Inception and Xception, applied on FER problem. The purpose of the paper is benchmarking the best architecture models, in order to help researchers to explore and investigate the best architectures for future research in FER based CNN models. For the comparative analysis multiple metrics were used such as Accuracy, Loss, precision, recall, number of parameters and model size, to conduct experiments facial expressions dataset was used from the AffectNet dataset with 287,651 images for training and 4000 images for validation represent eight facial expressions.
