Machine Learning - Classification MCQs
Machine Learning - Classification - MCQs 1. By default, SGD classifier follows this strategy for multi-class classification: Top of Form A) OvO strategy B) OvA strategy C) Both D) None Ans: B 2. SGD Classifiers and Linear Classifiers are strictly A) Binary Classifier B) Multiclass classifier C) Both D) None Ans: A 3. The greater the value for ROC AUC, better the model: Top of Form A) True B) False Bottom of Form Ans: A 4. The maximum value of the ROC AUC is Top of Form A) 0.8 B) 0.9 C) 1 D) 0.7 Bottom of Form Ans: C 5. Recall can be increased by increasing the decision threshold. True or False Top of Form ? A) False B) True Ans: A 6. Precision can be increased by increasing the decision threshold. True or False? A) True B) False Ans: A 7. Which of these is a good measure to decide which threshold to use?
