Neural Networks - nomalization done automatically?

martindemel

Hi,

 

a customer asked if our NN algorithm does an automatic transformation/normalization (Mean/Std) for the training data? This is said to be a good practice before running a neural network to gain more accurate results. (Often for artificial networks). 

 

Is this done in JMP automatically? I couldn't find any option.

 

Thanks,

Martin

Hi Martin,

 

If your customer is aiming to avoid model bias due to outliers in the predictors or irregular shaped distributions of predictors then the transform covariates feature corrects for these issues. If the goal is to avoid these issues then our transform covariates feature should perform better than a normalisation of the predictors and you may be able to offer a better solution than they are asking for.

 

Best,

 

Malcolm
