Example CNN Explanation
See how a CNN transforms an image: from the original photo, through Grad-CAM heatmaps, to the final overlay visualization.



What You'll See
Explore every layer of a CNN's decision-making process
Feature Maps
See what each layer focuses on as the network processes your image through different levels of abstraction.
Grad-CAM
Understand why the model predicted that class with heatmap visualizations showing the most important regions.
Prediction Breakdown
Track confidence scores and explore the top predicted classes with detailed probability breakdowns.
