WebFeb 25, 2024 · Scaling numbers in machine learning is a common pre-processing technique to standardize the independent features present in the data in a fixed range. When applied to a Python sequence, such as a Pandas Series, scaling results in a new sequence such that your entire values in a column comes under a range. For example if the range is ( 0 ,1 ...
