I've been seeing a lot of machine learning resources lately, all with one key thing missing: a simple, real world example of what I can use it for. Don't get me wrong, I don't doubt the examples are numerous, but for someone who has never even dabbled in machine learning, it would be nice to get a sense of some practical, cool things I can do with it.

Here's an example that immediately sprung to mind: http://akinator.com/ . It's a game that guesses what person or character you're thinking of by asking simple questions.

I really like that site, but I meant more from a developer point of view. For instance: how would I go about building akinator using one of these libraries?

Oh, that's what you were getting at. I agree. I would also love a step-by-step example of how to build something cool using machine learning.

Really good and intuitive introduction in to random forests. The linear regression comparison was a nice visual representation.

I can see you're new here, but if you think something is relevant to the site and a "Good Thing(tm)" then you should upvote it.

Then you should upvote it.

The title of this link sounds like a bug report.
