I'm not sure what your point is. What is the image, and what is the actual object?

I was replying to wting, but HN doesn't let me reply to a reply by the same author as a way to combat back-and-forth style arguments, I guess.

He said that experts doing that is "trained pattern matching gained through experience, i.e. machine learning."

But that's backwards: machine learning in this style is a model of something we observe in ourselves. The thing that's in us is the pipe, the machine learning algorithm is the picture.

You have to either wait a few more minutes till the "reply" link appears, or simply click on "link" link(!) and write your reply there.

Thanks! I've been an HN member for ~5 years and I didn't know this. :D
