Is there anything isn't fancy mapping?

Use that term to down play the effectiveness of the approach seems quite surprising. Consider human needs years of study to do the same thing, which usually also makes mistakes.

Even for the example, without much analysis, it's very easy to miss the part.

Don't get me wrong... but If it makes you feel better, I use DL for most of my research / projects. Well, after 7 years dealing with DL I couldn't really find a better single word to describe it.

How's "Fancy context dependent matching"? More dignified, right /s

In this case the context dependence part wasn't up to par, so it was just fancy mapping.
