Résumé :	In the field of computer vision applied to the medical sector, convolutional neural networks (CNN) and recurrent neural networks (RNN) have long been the dominant techniques. However, other deep learning methods, such as Transformers, have gained popularity. This study compares the performance of several deep learning models, including Vision Transformers (ViT), on tasks involving the classification of brain and breast images.The results indicate that models based on EfficientNet and ResNet outperformed other architectures in terms of accuracy and error minimization. EfficientNet particularly excelled in the classification of brain images, while ResNet showed the best performance for breast images. Although ViTs maintained good Top-K accuracy, their overall performance was inferior compared to the other models. This analysis highlights the importance of selecting appropriate deep learning architectures for specific tasks to optimize results in medical image classification.
