This question belongs to 'Data Mining & Business Intelligence' subject.

Marks: 10

  1. Accuracy:

Accuracy of classifier refers to the ability of classifier. It predicts the class label correctly and the accuracy of the predictor refers to how well a given predictor can guess the value of predicted attribute for a new data.

  1. Speed :

This refers to the computational cost in generating and using the classifier or predictor.

  1. Robustness:

It refers to the ability of classifier or predictor to make correct prediction from given noisy data.

  1. Scalability:

Scalability refers to the ability to construct the classifier or predictor efficiently; given large amount of data.

  1. Interpretability:

It refers to what extent the classifier or predictor understands.
