Python: CBSE AI metrics
Let Python do the maths
What are the three outputs?
TP, TN, FP, FN = 40, 45, 5, 10
acc = (TP + TN) / (TP+TN+FP+FN)
prec = TP / (TP + FP)
rec = TP / (TP + FN)
print(round(acc, 2))
print(round(prec, 2))
print(round(rec, 2))Let Python do the arithmetic while you focus on the meaning.
This program takes the four confusion-matrix values and calculates accuracy, precision and recall.
Output:
0.85
0.89
0.8
Accuracy = (40 + 45) / 100 = 0.85. Precision = 40 / 45, about 0.89. Recall = 40 / 50 = 0.8. Notice that round(0.8, 2) prints 0.8, not 0.80.
Try changing the values and see how each metric responds. This is great practice for your CBSE AI practical file.
