The Next Frontier in AI: Unsupervised Learning [video]
- gallerdude 10y agoI find unsupervised learning the most interesting when the system finds a pattern that humans can't even comprehend - being able to feel there is some sort of distinction, but being unsure what it is.
- randcraw 10y agoMe too. I think this is generally called "discovery" -- when a new concept arises because known concepts can't adequately explain an observation; established models can't capture it. IMO, it's easily the most interesting kind of learning. But frankly, I have no idea how a computational approach like machine learning could discover something new that's not just a combinatoric variation on known features. If you must invent a new dimension to model the unknown feature, how do you go about proposing one that's plausible and not absurd (like 4-dimensional space or 2-dimensional time)?
- gumby 10y agoWithout semantic understanding you don't know if the pattern is coincidentally correlated or is causally linked. Neural nets are great classifiers but there is much work to be done. We live in interesting times.
