@wla80 Don't worry about the broken links by the way, for this repository I will handle it.

I like some of this revision! Some parts I want to change though, as I try to keep a certain style and tone in this guide.

What about this?

When you work on a real Machine Learning problem, you should focus your efforts on your domain knowledge and data before optimizing your choice of algorithms. You should strive for Do Simple Things until you have to increase complexity. You should not rush into neural networks because you think they're cool. To improve your model, get more data and use your knowledge of the problem to manipulate the data. You should only optimize the choice of alogrithms after you have gathered enough data, and you've processed it well.
