What is Normalization?# Feature Scaling is an essential step prior to modeling while solving prediction problems in Data Science. Machine Learning algorithms work well with the data that belongs to a smaller and standard scale. This is when Normalization comes into picture. Normalization techniques enables us to reduce...
