Which machine learning algorithms require feature scaling?

Question

Can anyone tell me the machine learning algorithms that require feature scaling?

Answer 1

The Machine Learning algorithms that require the feature scaling are mostly KNN (K-Nearest Neighbours), Neural Networks, Linear Regression, and Logistic Regression.

The machine learning algorithms that do not require feature scaling is mostly non-linear ML algorithms such as Decision trees, Random Forest, AdaBoost, Naïve Bayes, etc.
