Select the Correct Statements regarding Normalization?

ANormalization technique uses minimum and max values for scaling of model.

BNormalization technique uses mean and standard deviation for scaling of model.

CScikit-Learn provides a transformer RecommendedScaler for Normalization.

DNormalization got affected by outliers.

Show Suggested 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).

Normalization? More like Abnormalization, am I right? *chuckles* Okay, I'll see myself out.

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

D is definitely true. Normalization can be affected by outliers in the data, so we need to be careful about that.

Option C is interesting, but I'm not sure if that's the correct answer. I'll have to double-check the documentation.

I believe option D) Normalization got affected by outliers is also important to consider, as outliers can skew the normalization process.
