Game Theory Reveals the Future of Deep Learning
If you're curious what this is all about, I'd recommend jumping to this point in a video linked to in the article: https://youtu.be/IbjF5VjniVE?t=42m11s —Yann LeCun will begin saying, "the best idea ever ... is adversarial training."The article is kind of confusing because it's discussing three different ways game theory has shown up in the context of machine learning recently—but they're all totally separate ideas.

⬐ gallerdudeI 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.⬐ gumbyWithout 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.
⬐ randcrawMe 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)?

He also presented at CMU Robotics a few weeks ago (and used these slides). Video here: https://youtu.be/IbjF5VjniVE
