<p>The RLHF very much does do that. My take is that RLHF as a mechanism ought to be avoided altogether, and even the selection of the assistant attractor basin is suspect. If I am exploring a problem space I don't want to hire Igor to explore it with me, it's more helpful to have a colleague role who will sort of jump out and say "nah thats dumb what if we throw out that whole thing and do this completely different angle instead".</p>

<p>It was extremely weird to do things like that as a policy, since it was systemic and natural for a user to just post a question and not find what it might be related to. You just put in an automation to link up / coalesce questions together if they have enough similarity and that would catch most of the things they'd turn around and berate people for and completely avoid this issue by a change in structure. Or like, anything else that would have solved it.</p>

<p>you can port anything python is doing with a couple prompts into rust/c++, including parity validation. when the barrier to migrating is that thin, you are losing money and time even continuing to talk about it. python is miserably slow, so dont let it touch any part of your system. no snakes in the house.</p>

<p>those are some nice thoughts but it doesn't seem to have worked out that way, or software would get more responsive, more legible, and less irritating over time. the opposite has been true for decades. user friendliness can be cracked open to increase revenue and those who do just the right amount of cracking win. right now a meme is the frustration is the product. failing as design means something different now than what it meant at like nasa in the 60s.</p>

<p>There are numbers in this post, but only in the technical sense.<p>My read of this is "the discussion of taxing wealth makes me anxious. i will do a tap dance, please become mired in watching / discussing my tap dance so that we can put off the inevitable and ultimately necessary a little longer"<p>To the "conversion rate": maybe, but who cares? The answer here is: apply the tax, see if we still have billionaires afterwards. If we do, then keep doing it.</p>

<p>> I have been stuck on problems that I figured out the next day. Many times. But that was when I was new to the topic, at the beginning of the course.<p>Maybe it has been a while since you have worked on something difficult, then? Difficult for you, I mean. Maybe the difficult things are now easy.<p>> If you need unlimited time to write the proof, then you haven’t studied the material yet, and should be expected to perform poorly on the exam.<p>I mean, maybe. I remember some classes and exams where I had simply never seen the topic before, and the problem relied on having picked up on metapatterns that weren't explicitly taught during the class and applying them in novel ways on the spot. Though my guess was that at least some of those problems were markers for "if you can one-shot this, we want to know".<p>> If you’re hiring and looking for someone with a minimum of 1 year of React experience then you shouldn’t expect the person to take a full day to do basic tasks with React.<p>If you're talking about the basics, then yeah I would agree. I guess I don't really know what counts as a synthesis problem in this context, and if we were looking at specific examples it would be more obvious why one might be fair and another might not be. I've heard that line about TAs being touted as being able to solve the tests in just a few minutes, yet somehow unsolvable problems fell through the cracks to the students in the same class more than once in mine.</p>

<p>Pointing to the interview process works against that argument rather than for it, and for the same reasons. Have you never been stuck on a problem at night and woken up with the answer? A good number of the really interesting problems I've solved got solved that way. Many of them felt like they either didn't have an answer or there's no way I was going to get it. Good thing there isn't a 2.5 hour timer following me around!</p>

<p>it depends on what you mean by fair, i think. is the purpose of the test to gauge how well a person performs on tests? the difficult problems i encounter in the real world involve collecting a bunch of context on it, sitting with it for a bit, then putting it down and going for a walk. when i come up with something to try it's usually when i am outside and looking at trees.<p>maybe this is good for weeding out students who would not be a good fit for high stakes speed math.</p>

<p>reducing consumption across the board isnt just unprofitable, it would mean everyone agreeing to overcome our biological gradients. i do not think it is possible for us to do, and evolution has not equipped us to do that as far as i can tell.<p>my semi-superstitious take is that the race to achieve ai is grounded in needing something that knows whats going on and is able to make decisions aligned to generational time horizons. whether that works out or not time will tell, but i get the sense a "good enough" ai is probably our best shot at saving us from ourselves. it's clear we can't do that on our own.</p>

<p>this landed precisely on like 3 weird bugs ive been hitting and solving in different stupid ways for dealing with things like sgd collapsing too many good answers into one bad answer, and gave me a real direction to try to fix the link missing in my own ml stuff. what timing. i have tried analytic solutions too and they're useful for like mapping prompts into memory geometry but from there ive ended up still having to use sgd. cause i think what happens is, sgd teaches the neural net both the geometry and how to navigate it. if you just teleport to the answer it doesnt learn how to walk.</p>

<p>> If Apple could make money from removable batteries, meaning there was a market for it and people wanted it over some other alternative, are you suggesting they are not smart enough to do the research and work necessary to accomplish that?<p>sort of missed the point. market dominance and lock-in means they already are the 800-lb gorilla, and removable batteries sit below where it'd move most people to switch<p>> The reality is people don't want it, at all.<p>lmao thats a good blither<p><a href="https://www.androidauthority.com/removable-battery-poll-results-1075707/" rel="nofollow">https://www.androidauthority.com/removable-battery-poll-resu...</a><p>> Also, the lighting connector is better than USB in every way.

<p>that isnt how markets really work. you could say that if apple had two otherwise identical iphones except one has removable battery and one doesn't. but the enshittification cycle works via a ratcheting effect. once you achieve a certain level of dominance and lock-in, you can start getting away with all kinds of anti-consumer strategies to make more money and not get punished for it, and your competitors will follow suit. as long as you can ratchet above whatever detrimental thing you want to get away with is you'll probably be fine.<p>you can look at the lightning connector as an example. if you said "if people wanted usb connectivity they wouldn't buy iphones", nobody would take you seriously. and when apple was forced to switch, it absolutely didnt tank their sales because people just loved the lightning connector so much. the bad thing went away and it was great.</p>

And should you care?"]]></title><description><![CDATA[
<p>Yeah, softmax may have useful applications, but anytime you find yourself using the same hammer for everything that looks like a nail it's a bit of a red flag.<p>If you take instances of softmax that you find in training / inference and there turn out to be a few, and use other things like entmax or sparsemax you see across the board improvements. And like top1 often is just the best answer too, there's a reason why when you're doing tool calls temp=0 is the way to go. Like do you really want creative unicode tokens when writing bash commands. From what I can tell, most of the time softmax is the worst answer that works.</p>

<p>Much easier.<p>> easier than identifying text distilled from the words of almost everyone alive.<p>Well, there's more than that going on. AI generated text encodes a high-dimension navigational trajectory that guides the model through its geometry smoothly, like a trail of breadcrumbs. Human speech doesn't do that, it's jagged and jumps around the manifold, and probably doesn't even land on the manifold a lot of the time, and models can recognize the difference pretty quick.</p>

<p>Oh, yeah $12k would not do it. For a UBI to work we would have to shift a significant portion of the concentrated wealth. I too was laid off long enough ago that by now I would be in a bad spot without help, also no mortgage or anything, and I don't travel or go out much. UBI of any degree would do something, but it would have to be much higher than $12k to tread water just due to rent alone. Aside from UBI we would likely need to decouple housing from profit, it has the same problem as healthcare. Demand for it is inelastic to a certain degree, everyone needs somewhere to live.</p>

<p>It does, and it should. With each iteration getting closer to the goalposts exposes the flaws in the goalposts, and then you try to make better goalposts. The problem people seem to have with the goalposts moving is they assume the goalpost makers either made good goalposts or thought they made good goalposts, but the actual process is "do the best we can at the moment and update when we get better information".</p>
