Can we order rows/columns in the confusion matrix in terms of meaningful confusion clusters.

Example using Cuthill-Mckee algorithm. I put a threshold at .05, it seems to help.

from scipy.sparse import csr_matrix
from scipy.sparse.csgraph import reverse_cuthill_mckee

graph = csr_matrix(CONFUSION_MATRIX > 0.05)
output = reverse_cuthill_mckee(graph, symmetric_mode=False)
print(output)
