Do models Normalize automaically

cliftonarms

Hi - two questions if I may.

1) Do any of the learning models normalize the input attributes automatically, or is it ALWAYS the designers responsibility to apply the normalize process.

2) Does the Random Tree model require its inputs normalized or does it work with the attributes as-is.

Thanks in advance.

As far as I remember, the Neural Network operator normalizes all the inputs (actually it's the default--you can deselect it if you will). Other operators require you do it yourself before.

I have never used Random Trees before, but trees in general don't benefit from normalization (the units don't matter at all).
