Differential GradCAM for CNN-based Fine-Grained Visual Categorization Model
Open AccessFine-grained classification requires a visual interpretation method that can capture subtle differences between similar classes, which classical approaches may not be able to achieve. In this paper, we introduce a new approach called Differential Grad-CAM, which can effectively localize differences between pairs of similar classes. This method helps us better understand the CNN-based models used in fine-grained classification and identify new regions for visual explanation. Differential Grad-CAM provides a new perspective for interpreting CNN-based models in fine-grained classification.
