Mathematical model for Eigen-CAM
Eigen decomposition-based CAM (Eigen-CAM) computes and visualizes the principle components of the final layer convolutional features for generating class activation maps. In other words, Eigen-CAM uses the elements of the highest principle component vector as weights for the linear combination in the CAM equation.
Let’s assume that
