Automatic normalization

 

A.numnorm()and P.numnorm(cn) can perform normalization on numeric variable.

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

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

3

=A1.numnorm("LotArea")

4

=A2.numnorm@r("LotArea",A3(2))

A1 Import the model data

A2 Import the prediction data

A3 Perform normalization on the variable "LotArea", return the processing result and processing record

..

A4 According to A3's processing record, the variable"LotArea" is normalized on the prediction data. @r means to do the same thing on the prediction data
