Select the Correct Statements regarding Normalization?

Show Suggested Answer Hide Answer
Suggested Answer: D

All are correct except a standard-only stream tracks row inserts only.

A standard (i.e. delta) stream tracks all DML changes to the source object, including inserts, up-dates, and deletes (including table truncates).

I practiced a question similar to this, and I think normalization typically uses mean and standard deviation, but I might be mixing it up with standardization.

I think normalization is definitely affected by outliers, but I can't recall if Scikit-Learn has a specific transformer called RecommendedScaler.

I remember that normalization often involves scaling data, but I'm not sure if it's specifically about min and max values or something else.

Wait, I'm confused. I thought normalization was about scaling the data, not just the model. I'll have to review my notes on this before answering.

Okay, I think I've got this. Normalization uses mean and standard deviation, and Scikit-Learn has a transformer called StandardScaler that does this. I'll select options B and C.

A? Really? Normalization has nothing to do with min and max values. Sounds like someone needs to go back to their machine learning basics.
