A tree ensemble on the same bulk-trash table is insensitive to column magnitude, but a k-nearest or linear path on that table is not. When should the team scale?
Select an answer to reveal the explanation.
Short Explanation
Think of a tree ensemble that does not care about column magnitude, and a k-nearest or linear path that does. Scale when the learner is magnitude-sensitive. Do not ritual-scale the trees.
Full Explanation
Apply scaling or standardization when the learner is magnitude-sensitive. Skip it as a cargo-cult step for trees. Always-scale, never-scale, and Polly miss that split.
