Normalization is the transformation of features:

Show Suggested Answer Hide Answer
Suggested Answer: C

Normalization is the transformation of features so that they are on a similar scale, usually between 0 and 1 or -1 and 1. This can help reduce the influence of outliers and improve the performance of some machine learning algorithms that are sensitive to the scale of the features, such as gradient descent, k-means, or k-nearest neighbors.

I'm feeling option C. Normalizing to a similar scale just makes good sense. Although, now I'm wondering if I should've just rolled the dice and gone with option D. Keeping things interesting, you know?

D is the one for me. Normalizing to different scales? That's just asking for trouble. Variety is the spice of life, but not in my data!
