I have this confusion matrix:
import pandas as pd
import seaborn as sn
import matplotlib.pyplot as plt
data = {'y_Actual': [3, 3, 1, 1, 0, 1, 2, 3, 1, 1, 1, 0, 2, 4, 3],
'y_Predicted': [1, 2, 2, 1, 0, 1, 3, 0, 1, 0, 0, 0, 3, 4, 2]
}
df = pd.DataFrame(data, columns=['y_Actual','y_Predicted'])
confusion_matrix = pd.crosstab(df['y_Actual'], df['y_Predicted'],
rownames=['Actual'], colnames=['Predicted'])
sn.heatmap(confusion_matrix, annot=True)
plt.show()
Is it possible to sort this confusion matrix by diagonal value in descending order ?
