Comparison of Prim algorithm and Kruskal algorithm. The HON-MST based on Prim algorithm and the HON-MST based on Kruskal algorithm were constructed, and the same methods were used for feature selection and classification. The classification accuracy of the HON-MST based on Kruskal algorithm was 98.16%. The classification accuracy of the HON-MST based on Prim algorithm was 95.18%. The classification result of the HON-MST based on Kruskal algorithm was superior to that of the HON-MST based on Prim algorithm.
