Rescale/Standardize Column Values
Rescaling is mapping the numeric values in a column to (0 to 1) range and it helps machine learning algorithms to converge faster. Standardization helps to map column values in such a way that they have mean of zero and standard deviation of one. This helps to compare feature along different scales. - Rescale a column using the MinMaxScaler of pre-processing module and this we will look into the results - Standardize a column using the StandardScaler class of pre-processing module. And then we will look into the results
