Here is something I’d like to see: You give the machine the formally specified ruleset of a game (go, chess, etc), wait while the reinforcement learning does its job, and out comes a world-class computer player.

Here is one reason, but it’s up for debate:
Deep learning courses rush through logistic regression and usually just mention SVMs. Arguably it’s important for understanding deep learning to take the time to really, deeply understand how these linear models work, both theoretically and practically, both on synthetic data and on high dimensional real life data.
More generally, there are a lot of machine learning concepts that deep learning courses don’t have enough time to introduce properly, so they just mention them, and you might get a mistaken impression about their relative importance.
Another related thing: right now machine learning competitions are dominated by gradient boosting. Deep learning, not really. This says nothing about starting with deep learning or not, but a good argument against stopping at deep learning.
In the last two days I alone wrote a prototype that can take a whiteboard photo, and automatically turn it into a mindmap-like zoomable chart. Pieces of the chart then can be rearranged and altered individually:

This was part of a company hackathon, and I had some infrastructure to help me regarding the visualization, but with the shape recognition/extraction, it was just me and the nasty python bindings for OpenCV.
Oh my god, look at 0-4-year old assaults, both ED visits and deaths. (Assault is the leading TBI-related cause of death for 0-4-year olds.) Some of those falling 4 year olds were assaulted.
There are worse fates than not being able to top your own discovery of general relativity.

Best of Rationality Quotes, 2014 Edition
Nice. If we analyze the game using Vitalik’s 2x2 payoff matrix, defection is a dominant strategy. But now I see that’s not how game theorists would use this phrase. They would work with the full 99-dimensional matrix, and there defection is not a dominant strategy, because as you say, it’s a bad strategy if we know that 49 other people are cooperating, and 49 other people are defecting.
There’s a sleight of hands going on in Vitalik’s analysis, and it is located at the phrase “regardless of one’s epistemic beliefs [one is better off defecting]”. If my epistemic belief is that 49 other people are cooperating, and 49 other people are defecting, then it’s not true that defection is my best strategy. Of course, Vitalik’s 2x2 matrix just does not allow me to have such refined epistemic beliefs: I have to get by with “attack succeeds” versus “attack fails”.
Which kind of makes sense, because it’s true that I probably won’t find myself in a situation where I know for sure that 49 other people are cooperating, and 49 other people are defecting, so the correct game theoretic definition of dominant strategy is probably less relevant here than something like Vitalik’s “aggregate” version. Still, there are assumptions here that are not clear from the original analysis.
I don’t know too much about decision theory, but I was thinking about it a bit more, and for me, the end result so far was that “dominant strategy” is just a flawed concept.
If the agents behave superrationally, they do not care about the dominant strategy, and they are safe from this attack. And the “super” in superrational is pretty misleading, because it suggests some extra-human capabilities, but in this particular case it is so easy to see through the whole ruse, one has to be pretty dumb not to behave superrationally. (That is, not to consider the fact that other agents will have to go though the same analysis as ourselves.)
Superrationality works best when we actually know that the others have the same input-output function as ourselves, for example when we know that we are clones or software copies of each others. But real life is not like that, and now I believe that the clean mathematical formulation of such dilemmas (with payoff matrices and all that) is misleading, because it sweeps under the rug another, very fuzzy, hard to formalize input variable: the things that we know about the reasoning processes of the other agents. (In the particular case of the P+epsilon attack, we don’t have to assume too much about the other agents. In general, we do.)

They’re running on the blockchain, which slows them down.
They can follow the advice of any off-the-blockchain computational process if that is to their advantage. They can even audit this advice, so that they don’t lose their autonomy. For example, Probabilistically Checkable Proofs are exactly for that setup: when a slow system has to cooperate with an untrusted but faster other. There’s the obvious NP case, when the answer by Merlin (the AI) can be easily verified by Arthur (the blockchain). But the classic IP=PSPACE result says that this kind of cooperation can work in much more general cases.
The primary decision-making mechanisms for them are going to basically be the same as can be used for existing organizations, like democracy, prediction markets, etc.
These are just the typical use cases proposed today. In principle, their decision-making mechanism can be anything whatsoever, and we can expect that there will be many of them competing for resources.
The thing that I think makes them interesting from a FAI perspective is the “autonomous” part. They can buy and sell and build stuff. They have agency, they can be very intelligent, and they are not human.
...Okay, that sounded a bit too sensationalist, so let me clarify. Personally, I am much more optimistic regarding UFAI issues than MIRI or median LW. I don’t actually argue that DAOs are dangerous. What I argue is that if someone is interested in how very smart, autonomous computational processes could arise in the future, this possible path might be worth investigating a bit.
An advanced DAO (decentralized/distributed autonomous organization), the way Vitalik images it, is a pretty believable candidate for an uncontrolled seed AI, so I’m not sure Eliezer and co shares Vitalik’s apparent enthusiasm regarding the convergence of these two sets of ideas.
I was unsurprised but very disappointed when it turned out there are no other posts tagged one_mans_vicious_circle_is_another_mans_successive_approximation. But Shalizi has already used the joke once in his lecture notes on Expectation Maximization.
I think I misunderstand your definition. Let feature a be represented by x_1 > 0.5, and let feature b be represented by x_2 > 0.5. Let x_i be iid uniform [0, 1]. Isn’t that a counterexample to (a and b) being linearly representable?
