Comparison Neural nets with general statistical approaches?

Hello altogether,

as I want to do a comparison between different statistical methods and neural nets I am searching for a good and interpretable dataset. Unlike datasets like the Sonar dataset, where patterns are not obvious to the human eye, I am searching for a dataset where the "patterns" are already known, so that I can validate both methods in detail.

I appreciate every tip of you!

Thank you in advance
