Min-Max standardization

 

It is a linear transformation of the original data to map the result value to [0 - 1].

Conversion function：x∗=x−min/max−min，max:max value of sample，min:min value of sample

For example, the "LotArea" in the house price data is an order of magnitude larger variable, Standardize it as follow:

A

1

=T("D://house_prices_train.csv")

2

=A1.max(LotArea)

3

=A1.min(LotArea)

4

=A1.run(LotArea=(LotArea-A3)/(A2-A3))
