== Explanation-based learning == 

 Ha! That didn't take long. I had to go to lunch, so I hit "Save" without adding a source. I just added a source and removed the {{prod}} tag from Explanation-based learning. The article is still pretty stubby, but it's a start, and the topic actually has a lot of literature about it. I do very much appreciate your fast response to anything that even sounds like it might be WP:OR.
