What did you have in mind specifically?

I used this for a project, not sure if I can share the data. It was social network data.
There were a lot of outliers, so after using StandardScaler, some things still had like feature value = +90!

This method was originally suggested to me by Yoshua Bengio. He spoke about it like it was a well-known thing, but I haven't really seen anyone else using it. Maybe it's one of those tricks that a bunch of neural networks people know, but no-one else.
