0:00 If you're building AI that searches through documents, here's a quick way to test it without writing hundreds of test questions or labeling a bunch of examples by hand. What you want to do is flip the problem. Point an AI at each document and say, "Make up a plausible question that only this document can answer." Now you've got a question paired with a document it came from. You can now feed that question back into your search and measure, "Did it find the right document?" You just turned a hard problem, which is having a bunch of labeled data, into a much easier one.

If you want to learn more techniques like this, I left some additional resources in the comments.
