I think that this is still a good advice. I would say: standardise your
data (for each feature: mean = 0, norm = 1) and throw it into an SVM.

If you have heaps of data, you can try random forests or gradient boosted
trees, that work very well.
The scikit-learn has good implementation of all these algorithms, but not
neural-network: they are too old fashion for hip coders to contribute

Nah, NIPS is about mathturbation, not things that work on real data,
