Feature scaling including 0

Hi, I have a numeric feature - Income with below values. There are 0 values too. I want to perform scaling but cant find an option. I saw this article in the documents section but it doesnt mention the steps in DSS.

https://doc.dataiku.com/dss/latest/machine-learning/features-handling/numerical.html 

STATISTICS

Min  Max  Mean  Median  Mode 

-29468
11438990
77273
173.89
0

 

Please advise.

Hi,

You can perform scaling on a feature from the Visual Analysis -> Models -> Design Tab -> Feature Handling. Select the feature and in the menu you will have several options to determine rescaling behavior and you can even switch to custom handling. Once you've confirmed the feature handling you can retrain your model.

Hope this helps.

Is there any way that dataiku itself can scale the features based on the model ?
