Implementing GradCAM on UNet with PyTorch for Multi-Class Segmentation

Описание: In this video, we’ll show you how to apply Grad-CAM (Gradient-weighted Class Activation Mapping) to the U-Net architecture for multi-class semantic segmentation using PyTorch. You’ll learn how to visualize which parts of the image influence the model's decisions the most — a powerful tool for debugging and interpreting deep learning models.
