Webb4.1 Diffusion map explore The Diffusion mapping is implemented in python. Figure.2 Diffusion map on two eigenvectors After ordering the face on the first eigenvector, we get the following faces order. Figure.3 Diffusion map face order From the figure below, it can been seen that the Diffusion map face order is right and it can successfully WebbI would like to be able to customize the color map to be normalized between [0,1] but I have had no success. I am trying to use ax_ and matplotlib.colors.Normalize but am struggling to get something to work since ConfusionMatrixDisplay is a sklearn object that creates a different than usual matplotlib plot.
