Our proposed framework, called CardioViT-CAM, consists of two main stages.First, we perform self-supervised pretraining using a Masked Autoencoder with a Vision Transformer to learn general cardiac features. Second, we perform supervised fine-tuning for classification of ASD, VSD, and AVSD. Additionally, we apply Grad-CAM++ to provide interpretable visualization of model predictions. | |
