Question 4

+2 marksOne or more correct options

Which of the following options is/are correct?

Select all that apply.

  1. A

    If the data contains many outliers, scaling using the mean and variance of the data is likely to not work very well.

  2. B

    RFE first removes a few features which are not important and then fits and removes again and fits. It repeats this iteration until it reaches a suitable number of features.

  3. C

    A pipeline cannot have any feature selection steps.

  4. D

    If you will execute model.fit() for a second time, it will start training again using passed data and will remove the existing results.
