Yes i go through Wikipedia. I get only 40 percent information about machine learning. As I am working on my project, so i need full detailed information from any good resourceful website.
Did you check their references? Wikipedia is my go-to site for research, but after years using it I started to check them also, and the information you find there and following the links within the text is usually huge.
But again, I never wrote a thesis, so I'm playing it by ear here...
