Q79 / 100

Why is min-max scaling or standardization often applied before training algorithms like k-NN or SVM?

Correct! Well done.

Incorrect.

The correct answer is B) Because these algorithms rely on distance or dot-product calculations, and features on larger numeric scales would otherwise dominate the result regardless of their actual importance

B

Correct Answer

Because these algorithms rely on distance or dot-product calculations, and features on larger numeric scales would otherwise dominate the result regardless of their actual importance

Explanation

Distance-based algorithms (k-NN, SVM, k-means) compute similarity using feature magnitudes. If one feature ranges from 0-1 and another from 0-100,000, the larger-scale feature will dominate the distance computation, so scaling features to comparable ranges (standardization or min-max scaling) is essential.
