So if humanity had had no biological neural networks to steal the general idea and as proof of feasibility, would machine learning & AI be far behind where they are now?

NNs connection to biology is very thin. Artificial neurons don't look or act like regular neurons at all. But as a coined term to sell your research idea its great.

NNs are popular now for their deep learning properties and ability to learn features from unlabeled data (like edge detection).

Comparing NNs to SVMs isn't really fair. You use the tool best for the job. If you have lots of labeled data you are more likely to use an SVM. It just depends on what problem you are being asked so solve. And of course you might feed an NNs output into an SVM or vice versa.

As for major achievements - NNs are leading for now because 1) most of the world's data is unlabeled and 2) automated feature discovery (deep learning) is better then paying people to craft features.

When I read these AI control problems I always think that an arbitrary human is being conflated with the AI's human owner. I could be mistaken that I should read these as if AIs own themselves - I don't see this case likely so I would probably stop here if we are to presuppose this.

Now if an AI is lying/deceiving its owner, this is a bug. In fact, when debugging I often feel I am being lied to. Normal code isn't a very sophisticated liar. I could see an AI owner wanting to train its AI about lying an deceiving and maybe actually perform them on other people (say a Wall Street AI). Now we have a sophisticated liar but we also have a bug. I find it likely that the owner would have encountered this bug many times while the AI is becoming more and more sophisticated. If he didn't encounter this bug then it would point to great improvements in software development.

What do Neoreactionaries think of the Islamic State? After all, it's an exemplar case of the reactionaries in those areas winning big. I know it's only a surface comparison, I'm sincerely curious about what a NR think of the situation.

While this is an interesting question - my take on the NRx was it was more anti-democracy then pro-Monarchy. So I think a better question for them would be: if fundamentalist Muslims become a democratic majority (via demographics) and vote in IS or the Muslim Brotherhood would that be a "big win" too? A less hypothetical question might be NRx's take on the state of Iraq's fledgling democracy.

Russia is already approximately 15% muslim, with huge differential birth rates between christians and muslims. And that 15% understates the real issue for violence and control - who has the most young men. I've seen numbers that by 2020 (!) half the Russian army will be muslim, and that majority will only grow from there.

Doesn't this analysis depend on army technology not changing? 100 years ago this would be spot on but if in the next decade we continue to see smaller armies of people being more and more effective you could have a Russia with an even smaller army without muslim leadership.

The same is true for the civilian side. Even with large numbers of disaffected young males - near term technological surveillance could prevent them from organizing in any meaningful way.

Being 100x more productive is about not solving hard problems you don't need to. Spending time thinking about ways to avoid the problem often pays off (feature definition, code reuse, slow implementations, ect). Much of the best practices that you read about are solving problems you wish you had - I wish my problem was poor documentation because that means someone actually cares to use it. I was always surprised by how bad the code was out in the wild until I realized it was survivor bias - the previous owner deferred solving some problem for a long time.

Comment by is4junk on Open thread, Mar. 23 - Mar. 31, 2015 · 2015-03-24T23:40:37.356Z · LW · GW

I don't think we would be that far behind.

NNs had lost favor in the AI community after 1969 (minsky's paper) and only have become popular again in the last decade. see http://en.wikipedia.org/wiki/Artificial_neural_network

The only crossover that comes to mind for me is the vision deep learning 'discovering' edge detection. There also is some interest in sparse NN activation.

Cthulhu may swim slowly. But he only swims left.

I assume the mistake was assuming Cthulhu was swimming faster. AFAIK no one disputes the only swims left part.

Question on infinities

If the universe is finite then I am stuck with some arbitrary number of elementary particles. I don't like the arbitrariness of it. So I think - if the universe was infinite it doesn't have this problem. But then I remember there are countable and uncountable infinities. If I remember correctly you can take the power set of an infinite set and get a set with larger cardinality. So will I be stuck in some arbitrary cardinality? Are the number of cardinality countable? If so could an infinite universe of countably infinite cardinality solve my arbitrary problem?

edit: carnality -> cardinality (thanks g_peppers people searching for "infinite carnality" would be disappointed with this post)

I'd look for a good headhunter in your field (assuming it is not too niche). Let them get the commission for finding you a job.

  • Update your linkedin profile and see if any contact you.
  • Talk to a recruiter in a company that is a near fit for you even if they aren't hiring now and ask if they have worked with any headhunters in the past.
  • Go to a Job fair in the US - not for job but to interview headhunters

Why even read left wing articles if they upset you?

My take is that if the public space was skateboarder and homeless friendly, the author could easily write a similar article on how that scares [insert other victim group] away from the public space.

As for why it is written that way, Kling's book The Three Languages of Politics is a good explanation. The left likes to think in oppressed verses oppressor terms.

Thanks for posting this article. There is a park being planned near me and there are certain architectural features I now want it to consider ...

Comment by is4junk on Twenty basic rules for intelligent money management · 2015-03-20T19:14:25.845Z · LW · GW

Brokerage accounts (fidelity/etrade) are better then bank accounts in every way (in the US). Use them with a margin account to safely maximize your investments. The margin account will basically function as an overdraft / short term loan at very favorable rates. Reasons:

  • direct deposit in to your brokerage account - all surplus money should be sweeped in to an index fund (SPY or global equiv)
  • You can have a ATM card and do all your checks through them usually for free
  • they all have bill pay service for free
  • depositing checks - they can be mailed in
  • Even if you don't invest the money it will automatically be in a money market account earning you interest
  • investment interest payments (on the margin) can be tax advantaged unlike credit card payments

I didn't have a bank account for over a decade. There is no reason to think about checking and savings being separate things.

Concerns about margin account being scary are only that way when you margin a substantial fraction of your account. If you are under 10% and invest in stable index funds you won't have a worry.

instead of investing in SPY consider Berkshire Hathoway (brk) for the tax advantages - (Warren Buffet doesn't like to pay taxes). I'd look at costco's sharebuilder if you can't afford to buy 1 share.

Comment by is4junk on Two methods on akrasia / unhealthy habits / addictions · 2015-03-20T01:29:40.644Z · LW · GW

I have a hard time with the goal setting phase. Do I really want the goal? Would doing X really achieve the goal? Even if doing X achieves the goal would the cost be too high? Sometimes I think this is akrasia other times I think it is being accurate that the goals are wrong.

For most of the work stuff I find it easier to remember where to find things rather than the things themselves. The hard stuff is the undocumented and constantly changing locations and procedures where a search is likely to find out of date junk.

Comment by is4junk on What subjects are important to rationality, but not covered in Less Wrong? · 2015-02-28T19:23:55.144Z · LW · GW

I think there would be more contributions. For instance, StarSlateCodex seems to get more engagement by discussing the Taboo topics. Its widely believed that many LWers left here but visit those types of sites. Could LW fully explore rationality without the those topics? Probably - but it would be dry and boring.

I think that the reddit code base (LW's) would be a better platform for the rationality community then a bunch of random unconnected websites. I had proposed an egalitarian software solution which I think would allow the Taboo topics to be discussed without forcing them on anyone.

Comment by is4junk on What subjects are important to rationality, but not covered in Less Wrong? · 2015-02-28T17:29:01.234Z · LW · GW

What are the current developments? Is anything dominant now? Wiki claims Logical Positivism was dominant until 1960.

Also do the current developments matter? Would any of the hard sciences do things differently? Did the change affect the soft sciences?

Comment by is4junk on What subjects are important to rationality, but not covered in Less Wrong? · 2015-02-28T03:45:01.685Z · LW · GW

The missing topics are labeled Taboo. I believe the Less Wrong community could contribute quite a bit to each of these but they are just too painful. I wish there was a way to discuss aspects of them without falling into the tired ruts. I am convinced that some LWers have gone down these paths and returned or discovered something insightful. But the current Taboos on it makes it difficult to broach these topics. Also there are trolls for many of them...

  • Diets (Keto, low carb)
  • Democracy (NRx)
  • Red pill (PUA)
  • IQ (gender, race, culture, marshmallows)
  • Climate change (science theory)

I always liked that episode. Before I thought being emotionless was effortless for Spock. When I saw that episode I realized he had to work at it.

Comment by is4junk on Money threshold Trigger Action Patterns · 2015-02-22T22:08:37.268Z · LW · GW

Thanks for the insights. I am not in the industry. I hadn't thought about the tax and creditor aspects of life insurance. I can see how those could become murky really quick.
As for the cryogenics, yes I was thinking of some sort of life insurance policy. Maybe I should take it off my list since 'permanent death' would be financially devastating. My thinking was you probably have other things to focus on if you can't pay it out of pocket.

As for house and renter insurance, I don't think the insurance company's profit is a good indicator of how much expected value they are for an individual - maybe a best case scenario. For example, these factors would vary by individual. Who is subsidizing them?

  • Subsidizing irresponsible dumb-asses (deep frying your frozen turkey indoors would qualify)
  • Subsidizing those with more stuff, better record keeping of it, and flat out liars
  • Subsidizing those who manipulate the claim adjuster better (are they as sympathetic to your case?)
  • Subsidizing bad law
  • Subsidizing moral hazard
Comment by is4junk on Money threshold Trigger Action Patterns · 2015-02-20T22:58:33.067Z · LW · GW

Other trigger points should be when to self-insure. The usual guidance is when you could easily pay the replacement costs. Insurance is always a low odds bet. The only economic reason for it is when losing the bet would devastate you financially.

  • electronics insurance (self insure only)
  • cryonics insurance (self insure only)
  • travel insurance (self insure only)
  • renters insurance (self-insure as soon as you have enough savings to easily cover your essentials)
  • car insurance (I don't think you can legally self insure all of it)
  • house insurance (self insure if rich and no mortgage)
  • health insurance (self insure if super rich)
Comment by is4junk on An alarming fact about the anti-aging community · 2015-02-17T16:36:49.135Z · LW · GW

From a quality of life POV, I would think that joint replacement (knee, hip, elbow) would be a huge improvement for many people. Outside of organ growing is there any progress on growing joints?

When Roomba came out I expected vast progress by now. Some company would actually make one that works all the time for the whole house. Now I am not second guessing the the IRobot corporation - maybe they could do it but the market is happy now. How hard is it with today's know how to make one that

  • doesn't get stuck on rugs, cords, clothes, or under things ever
  • can remember where it needs to clean and you don't have to use virtual walls
  • can remember how to get back to its docking station before its battery runs out every single time
  • make a docking station where it can drop off its dirt so I don't have to check it more then once a month

Its stuff like this that makes me wonder how much progress we are actually making. Is it a solved problem with no market (at the price point) or is it a problem in robotics?

The actual function of Karma as you describe doesn't bother me. I'll continue voting as usual. The anti-kibitzing option just hides the votes so I don't see them. For me I hope out of sight out of mind actually works for this problem.

Comment by is4junk on Have you changed your mind recently? · 2015-02-09T20:42:06.039Z · LW · GW

I used to think this Karma Score stuff would be helpful to filter low quality posts. But I see many people get downvoted for tribal reasons and I also see many upvotes on posts that I have trouble deciphering (sockpuppets?). So usually, when I see a post downvoted to oblivion I end up clicking on it anyways which defeats the whole purpose of using the Karma Score to help me filter out bad posts. I also waste a bunch of cycles wondering about the votes (who are these people).

TL;DR I have decided to try using firefox to view lesswrong with the anti-kibitzing option turned on (see preferences).

Does anyone know if any companies are applying NLP to software? Specifically, to the software ASTs (abstract syntax trees)?

I have been playing around with unfolding autoencoders and feeding them Python code but if there are researchers or companies doing similar I'd be interested in hearing about it.

Robotics will get scary very soon. quoted from link:

The conference was open to civilians, but explicitly closed to the press. One attendee described it as an eye-opener. The officials played videos of low-cost drones firing semi-automatic weapons, revealed that Syrian rebels are importing consumer-grade drones to launch attacks, and flashed photos from an exercise that pitted $5,000 worth of drones against a convoy of armored vehicles. (The drones won.) But the most striking visual aid was on an exhibit table outside the auditorium, where a buffet of low-cost drones had been converted into simulated flying bombs. One quadcopter, strapped to 3 pounds of inert explosive, was a DJI Phantom 2, a newer version of the very drone that would land at the White House the next week.

Comment by is4junk on The morality of disclosing salary requirements · 2015-02-09T00:14:47.101Z · LW · GW

My view is that the company knows what the job is worth, and the applicant does not...

Is this a problem now a days with sites like glassdoor? Or maybe some industries are not well represented.

When interviewing if you can get multiple job offers then you can play them off each other (in some industries). I don't have any experience with government work though.

I mean it in this non-flattering sense rent-seeking.

I envision all sorts of arbitrary legal limits imposed on AIs. These limits will need people to dream them up, evangelize the needs for even more limits, and enforce the limits (likely involving creation of other 'enforcer' AIs). Some of the limits (early on) will be good ideas but as time goes on they will be more arbitrary and exploitable. If you want examples just think of what laws they will try to stop unfriendly AI and stop individuals from using AI to do evil (say with an advanced makerbot).

Once you have a role in the regulatory field then converting it to fun and profit is a straight forward exercise in politics. How many people are in this role is determined by how successful it is at limiting AIs.

Comment by is4junk on Have you changed your mind recently? · 2015-02-07T17:13:30.856Z · LW · GW

Why not try to exploit the singularity for fun and profit? Its like you have an opportunity to buy Apple stock dirt cheap.

  • Investment: own data center stocks initially. I am not sure what you would transition to when the AI learns to make CPUs.
  • Regulatory: make the singularity pay you rent by being a gatekeeper. This will be a large industry worldwide. Probably the best bet.

At the very least you should be able to rule out bad investments (time or money).

  • Energy
  • Land
  • Jobs that will be automated

I would think most people change their minds on these topics but would simply lie about 1 & 2. There are several threads about religious people turning atheist using this strategy.

I think the grand thing difficulty is that a change would require a large personal commitment if they wanted to be self-consistent. The difficulty is laziness - 'I'd have to rethink everything' or even worse 'I'd be evil to think that'.

It would depend on how bad travel was without cars yesterday. Historically, it was horses which must have been really bad. I think if they knew back then about speeds, traffic, and conditions they still would have done it. Parts of China and India have proved it quite recently (last 50 years).

Now if we had most people in high density housing, good transport (both public and private), and online ordering/delivery then maybe cars would be very restricted.

I mean unfriendly in the ordinary sense of the word. Maybe uninviting would be as good.

Perhaps a careful reading of that disclaimer would be friendly or neutral - I don't know. My quick reading of it was: by interacting with AI Impacts you could be waiving some sort of right. To be honest I don't know what a CCO is.

I have nothing further to add to this.

I am not sure. A quick search on LessWrong only lead me to Meet Up: Pittsburgh: Rationalization Game

What I am proposing would be more of an exercise in argument structure. Either the 'facts' are irrelevant to the given argument or there are more 'facts' needed to support the conclusion.

In college, I had a professor ask us to pick any subject, make-up any 'facts', and try to make a compelling argument. He then had us evaluate others peoples essays. Let's just say I wasn't impressed with some of my fellow classmate's arguments.

Sometimes you see this in the courtroom as a failure to state a claim

Comment by is4junk on My Skepticism · 2015-01-31T05:24:13.607Z · LW · GW

I don't think there is a way out. Basically, you have to continue to add some beliefs in order to get somewhere interesting. For instance, with just belief that you can reason (to some extent) then you get to a self existence proof but you still don't have any proof that others exist.

Like Axioms in Math - you have to start with enough of them to get anywhere but once you have a reasonable set then you can prove many things.

Comment by is4junk on My Skepticism · 2015-01-31T02:41:19.845Z · LW · GW

I would agree if you can't trust your reasoning then you are in a bad spot. Even Descartes 'Cogito ergo sum' doesn't get you anywhere if you think the 'therefore' is using reasoning. Even that small assumption won't get you too far but I would start with him.

Overdosing on politics to become desensitized is genius. However, I seem to have too high of tolerance for it.

The singularity aspect is more of a personal inconsistency I need to address. I can't think that the long term stuff doesn't matter and have a strong opinion on the long term issues.

Are human ethics/morals just an evolutionary mess of incomplete and inconsistent heuristics? One idea I heard that made sense is that evolution for us was optimizing our emotions for long term 'fairness'. I got a sense of it when watching the monkey fairness experiment

My issue is with 'friendly ai'. If our ethics are inconsistent then we won't be choosing a good AI but instead the least bad one. A crap sandwich either way.

The worst part is that we will have to hurry to be the first to AI or some other culture will select the dominate AI.

Politics as entertainment

For many policy questions I normally foresee long term 'obvious' issues that will arise from them. However, I also believe in a Singularity of some sort in that same time frame. And when I re-frame the policy question as will this impact the Singularity or matter after the Singularity the answer is usually no to both.

Of course, there is always the chance of no Singularity but I don't give it much weight.

So my question is: Has anyone successfully moved beyond the policy questions (emotionally)? Follow up question: once you are beyond them do you look at them more as entertainment like which sports team is doing better? Or do you use them for signalling?

I agree there still would be very easy ways to punish enemies or even more common 'friends' that don't toe the line.

I do think it would identify some interesting cliques or color teams. The way I envision using it would be more topic category based. For instance, for topic X I average this group of peoples opinions but a different group on topic Y.

On the positive side, if you have a minority position on some topic that now would be downvoted heavily you could still get good feedback from your own minority clique.
