Webb9 mars 2024 · From there, we’ll dive into Grad-CAM, an algorithm that can be used visualize the class activation maps of a Convolutional Neural Network (CNN), thereby allowing you to verify that your network is “looking” and “activating” at the correct locations. We’ll then implement Grad-CAM using Keras and TensorFlow. After our Grad-CAM ... Webb15 aug. 2024 · Grad-CAM: A Camera For Your Model’s Decision Lights, CAM, Gradients!
