If we recall the theory of KNN, it is a distance-based algorithm, and feature scaling is an important step that we intentionally skipped. Let’s see if we can improve the model performance with feature scaling.
Effect of feature scaling on KNN
KNN makes decisions by identifying the votes from the training data points nearest to the test data point (majority voting based on the k value). ...
