A UMAP plot is a graph displaying the u201cUniform Manifold Approximation and Projectionu201d, which visually shows how separable the classes under consideration are with respect to the selected group of features. It is a 2D plot and represents each class as a cluster of points in a unique color. You want to have these clusters as far away from each other as possible for the best classification. You can visually inspect UMAP plots for your selected sensors and feature groups. We recommend choosing sensors and feature groups that result in maximally separated clusters.
