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?
