It isn't self-tuning, and it doesn't "learn."

From the paper:
"The three constants c_i need to be set by the implementor"

Under "Future Directions":
"One obvious thing to do with this system is to have it learn and tune its parameters with experience." The work presented in the paper does not do this.

"This network was designed in an ad-hoc, if traditional, way. First, a human tried to control the bicycle with the simulator. After many attempts, the human finally became a somewhat skilled operator of the bicycle ... the human at this point was able to describe the key parameters which were being attended to, and based on this, the two-neuron network was designed." By "designed," the author means "the three constants were selected."

This sounds like the "arbitrarily complex procedure" you are looking for.
It seems important to me that we be sure to ask some questions of what the "task" consists of, and the effects of variable tasks, before making too much use of this.
I can't parse your question, sorry.
Good question. Addressed that here: https://news.ycombinator.com/item?id=16216455

Our top focus is order approval lift. Zero fraud is cool and all (and makes for a good posting title) but is really just an assurance that you should be comfortable as we start to approve way more orders.

> Bitcoin is currently the crypto equivalent of gold.

Why is this a good thing? Nobody uses gold as a store of value anymore because it just wasn't viable going forward. Why would Bitcoin be any different?
In my opinion, Bitcoin trading is about trading bad money for good money. When the bubble burst, the good money will be in the pockets of former Bitcoin "market makers", while the loses will be in the side of the enthusiasts/idealists/naive.
How about stock.
This is never a justification. Read war of Vendee.
Lead is useful. Even gold is somewhat useful.

Bitcoin is an asset that’s neither productive (stocks, bonds, land) nor useful (oil, wheat, lead). That’s quite unusual.
That's the case now, but that was certainly not the case in the late 19th century when gold fever struck. The only use back then was jewelry and the fact that is was rare.
I use Developer as my only browser. Never had any issues. It's not a buggy alpha version or something.
While the parent's statement is wrong; it essentially makes the correct point. Gold has value as it is a store of wealth and maybe a case could be made that Bitcoin is that; though it is tougher now. Gold is used as a medium of exchange and the underpinnings historically for currency as some currency is literally minted out of it or was backed by it.

However, other assets have value because they are useful. Per your examples a house is shelter and a stock is a virtual representation of the physical assets and receivables of a corporation which I should add has extreme market liquidity. Other assets like vehicles provide transportation and heavy machinery make products. I like Bitcoin and it may become/stay an asset class like gold; very illiquid and a store of wealth, but if that fails to materialize or continue after this speculation Bitcoin will be a lot more the AltaVista/Yahoo/Dogpile to Google search than the Gold to Cash analogy.
No. A number of successful countries started off "as a poorly-developed state engaged in outright war and proxy wars". The U.S. itself, for example. And Israel, for another. Stop making excuses.

And, as if the arms race of the Cold War did not involve choices made by the Soviets! Come off it. They could easily have chosen not to get dragged into an arms race. But instead they chose no only to play that game, but to then start quite a few expensive proxy wars... Korea, Vietnam, Afghanistan, a number of civil wars in Africa, Nicaragua, ... These were their choices.

They were under a dollar after dropping for several days straight, not sure where they are now or where they're going to end up either in the short term or once SegWit finally comes into widespread use. (It'll probably take a while for the transaction cost estimators and average transaction fees to catch up in any case; there's a lot of software generating very slow, conservative fee estimates.)
Bitcoin isn't working so now we're adding more complexity on top of it. What could possibly go wrong?
That's effectively the same thing as zero fraud for anything that matters, if you never have to pay for it, no?

I mean, I guess if someone fraudulently signed up for a subscription, you'd lose the future expected monthly subscription fees or whatever.

But it's pretty much good enough. When I saw "zero fraud" advertised, my immediate assumption was that they paid for any fraud, and they were confident they had fraud low enough to do that and still be profitable. No other way to get truly "zero".
You should apply this kind of logic to scientific papers too. It's infuriating that some papers manage to get published that have the type of errors that would at the very least gotten a letter grade taken off(if not an F) for papers I wrote in undergrad physics labs.

The first nuclear power plant connected to the grid to actually power stuff was one in the SU. The first artificial satellite, first animal in orbit and first human in space are all from SU. The first properly continuously inhabited space station Mir was also theirs. Then they (Russian which is de facto descendant of and was most important part of SU before it dissolved) also contributed to the ISS along the US. They also made the Tsar Bomba, FOBS, AK, Katyusha, RPG, Su, MiG, T tanks, etc. and had other weapon, space and medicine related achievements.

In the interwar period in 1919-1921 war SU was also badly beat up by 'weaker' Poland (that only gained independence in 1918 after 123 years since it was partitioned completely in the last of 3 partitions) and it and its satellite states in Warsaw Pact/Eastern Bloc grew to be strong enough to engage in a stand off with USA and the West.

If that's not much then I don't know what is.
Jewelry doesn't have inherent value. Guns, cars, food and shelter has inherent value. Gold has been a luxury good long before it had any practical applications.

Of course. And Bitcoin historically has provided speculative gains. The point is they can have value without being used to buy things directly.

You say this as if a large-scale, mainstream switch to a decentralized currency is right around the corner. With how volatile the market has been, what makes you think a switch like this is even remotely near-term?
I agree, this might be "good enough" for now; thanks for the tip
I don't see how this is the case.

Ok, so the Fork will have the same/similar technology behind it, and will be distributed to the same people at the beginning. But, it's not like it's being supplanted. Bitcoin will still be Bitcoin.

I suppose the real world example would be to send an amount of copper to people with gold, it wouldn't change the value of the gold much. Bitcoin has many issues, but I don't see this as one.
A long time ago they changed it so that using '+' would cause it to search within "google plus" entries. They did this completely silently and the sad thing is it took people quite a long time to figure out that the meaning had been changed.
I've said this elsewhere, but it bears repeating. Bitcoin is capable of handling high transaction volume with low fees. The BCH fork was created to support this case. The BTC chain's devs mostly work for Blockstream, who's business model is to create layer 2 payment solutions, so it's in their interest to choke off the main chain. And it looks like they are succeeding.
Large corporations often make deals with other large corporations, and they prosper. Workers used to do better when a larger percentage of them collectively bargained. But somehow, the possibility that citizens, who are represented by various local governments, would use those governments to cooperate with each other across the lines on the map sounds like science-fiction and is disparaged as far-fetched and unworkable in many of the comments here. What is it that Americans don't understand?

Do they understand that Seattle, home of HQ1, has home-grown homelessness that is rising?

Do they understand that Amazon will automate away any job outside the executive suite that it can?

Do they understand the power that Amazon will have over the lucky city that makes the investment?

Do they understand that 50 years is now the standard term for the tax breaks that Amazon will be offered?
Take this to an extreme, and for the right price I can eat a lot of broccoli.

No, Bitcoin is the crypto equivalent of Monopoly money: it is unreasonable to use it for anything but little fun. For real world use cases there are better solutions, including other cryptocurrencies.

I'll test this out, sounds like a good strategy. I have also done something slightly different which is giving him a word without telling him the meaning, just playing with the sound. After a while once he can repeat it and say it fluently, I would explain what it means. By the time I do that, he's already said the word a bunch of times so I tricked him into "knowing" the word and there's nothing he can do to go back in time :)
Not stock. With stock you have a share of physical assets and cash flow.
Its usefulness as a metal/ornament is not why it's priced as it is. That's due to rarity, authenticity, and acceptance as a value store. And that's just another way of saying it's good for debt accounting. Bitcoin, seashells, obsidian, and gold share(d) those properties. The price is what people are willing to pay for N units in the literal or de facto “ledger”.
"The incentive can also be funded with transaction fees. If the output value of a transaction is
less than its input value, the difference is a transaction fee that is added to the incentive value of
the block containing the transaction. Once a predetermined number of coins have entered
circulation, the incentive can transition entirely to transaction fees and be completely inflation
free."

It's the design, folks. Read the paper and think about what it's saying.

Satoshi was acutely aware that 1MB blocks could only encode a couple thousand transactions. So what do you think "the incentive can transition entirely to transaction fees" means in practice?

Not a <$100 fee, that's for sure.
Do you see yourself picking up another cryptocurrency in the future? One that isn't just an asset to be held but was accepted as a form of payment on a larger scale?
Yeah, thats what I mean, isn't it worse to be able to create a forced transaction than to be able to fork the chain at any given point?

How is this baffling? 99% of people who buy bitcoin and other cryptocurrencies don't care about freedom, disrupting the financial system or any of that other ideological issues. They simply want to make money (USD, EUR, JPY, what have you).
> Gold as a metal has an inherent value though.

The price of gold isn't really related to it's use in electronics however.

> The value associated with bitcoin seems purely sentimental.

Scarcity is a factor. Admittedly not all things that are scarce are valuable but it's a necessary precondition.

There are other examples of items that lack inherent utility but have value and they too are often used to store wealth: art, antiques etc. spring to mind.

If everyone decided tomorrow that Ming Vases were rubbish they would cease to be valuable. That's surely as "sentimental" as Bitcoin - value based on scarcity and consensus.
What is being suggested here is a cartel. Yes, if one city didn't agree to signing up for the non-aggression agreement at all, they may stand to win, but if everyone agrees on non-aggression, then whomever the eventual winner is wins the deal for much cheaper. Of course, in practice, defining what constitutes aggression and tax cuts would be quite difficult, but in theory players competing in a winner takes all market could still work.
how do you deal with things that require your wife to understand too? Do you spend your time saying things twice?
Family is a choice.

That's the point - it's the choice they want you to make. It's how the system keeps running - including the pensions they will receive, etc. Don't get me wrong, I pay that "tax" too, but it makes sense to provide that incentive.
Yep, they produced a lot of research. So, how did they apply these technologies to create products the market actually want? And abundance for all people to lead better lives?
Somewhat related, Montana may have beat most states to the punch so to speak, but theirs was actually just an executive order (which can be reversed).

Oh I absolutely do, and IMO this scientific irresponsibility is far more dangerous within fields that actually call themselves "sciences" -- at least these "indexes" don't claim to be scientific (even if some people erroneously assume otherwise, such as my former self). There are certain fields with the word "science" in the title that are notoriously awful in this respect. (I won't name names, just for the sake of simplifying the discussion, but it's not hard to find out.)

Even the notion "hard science" vs "soft science" is a very slippery slope, IMO. We should not seek to speak of "hard" vs "soft" science; instead, we should focus on distinguishing good from bad science. Even science performed on incredibly difficult and complex topics (with immensely numerous confounding variables, near impossibility of controlled trials/experiments, etc.) can still be done correctly! One simply needs to adhere to statistical rigor and qualify conclusions from data with appropriate levels of uncertainty, withhold conclusions with no predictive power or statistical significance, and publish meaningful negative results just as frequently as positive results.

This movement of lax scientific rigor within fields that call themselves "sciences" is incredibly dangerous and threatens to erode the credibility of all results/fields that call themselves "scientific" in the eyes of the general public -- the vast majority of whom do not have the time, energy, or ability to review each field and/or publication to understand how rigorous and honest it actually is.

When you read about problems of anti-intellectualism and public distrust in science, the first thing we should do is look to the "sciences" (and bad journalism) that justify this distrust.
> Bitcoin Cash is the only 'true' fork that survived beyond the splitting of the BTC chain

This seems like a "No True Scotsman" fallacy and isn't correct unless you take liberties with the concept of "true fork" or you are making an observation about the lack of mass-scale adoption of the smaller forks.

Every protocol change in Bitcoin is in the most literal sense a "fork". There was a time at which the proposed protocol change might or might not survive the fork attempt. The community (developers, miners, holders, transactors, etc) all vote with their feet.
Lightning needs two additional transactions to load and unload payment channels, maximum transaction amount is 0.04 BTC, and it is at least 1 year away from maturity for large scale deployment.

Current price bubble will bust long before that, and no one will care about LN anymore.
I give the authors a little bit of a break because they're sort of more thinking about the meta problem of how to build an automated system to create a controller. From that standpoint, the original paper is more introducing the early landscape of the problem and documenting some early stabs at it. Introducing the question of how to get that automated derivation to arrive a simple set of end controls for the system as simulated.

So is gold. Most gold ends up in vaults (see [0]), where absolutely nothing is done with it. If we would price it for practical stuff (for it's thermal and electric properties), it would be worth much, much less.

Also, gold is not scarce by any means, just expensive to mine.

It's interesting that I had a similar experience with the AirPods I got as a gift. I would never have bought them myself, but now that I have them I keep discovering ways in which they solve a 'problem', however trivial, that I had in the past with wired earbuds/headphones, or offer a new use-case. I often find myself having one of the earbuds in throughout the day, and I wasn't too much of a headphone-user to begin with.

If they'd break, I'd probably buy new ones immediately, despite the price.

(Well, I'd research the possibility of cheaper bluetooth earbuds first)
