Question 28

+1 markOne correct option

Consider following common data:

python
print("Classification Report:\n", classification_report(y_test, y_pred))
text
Classification Report:
              precision    recall  f1-score   support


           0       1.00      0.33      0.50         3
           1       0.97      1.00      0.99        73


    accuracy                           0.97        76
   macro avg       0.99      0.67      0.74        76
weighted avg       0.97      0.97      0.97        76

Consider the above classification report on a model where y_test contains the original labels and y_pred contains the predicted labels.

Based on the above data, answer the given subquestions.

Consider the following and select the corrrect option:
Assertion: This is a good model as we see a very high accuracy of 97%
Reason: In the case of imbalanced datasets, accuracy might not be the best metric for evaluating a model

  1. A

    Both the assertion and reason are correct, and the reason is a correct explanation of the assertion

  2. B

    Both the assertion and reason are correct, but the reason is not a correct explanation of the assertion.

  3. C

    The assertion is correct, but the reason is incorrect.

  4. D

    The assertion is incorrect, but the reason is correct.

Show answer
