The mechanisms the author describe are used for RLHF, but are not sufficient for training the recent slew of “reasoning models.” To do that, you have to generate rewards not based on proximity to some reference full answer transcript, but

Thank you for coming into this endless discussion with actual references to relevant authorities who have thought a lot about this, rather than just “it’s obvious that…” FWIW though, last I heard Hofstadter was on the “LLMs aren’t conscious

Technically solar power is just fusion power transmitted via photons across space. Maybe solar qualifies ;-)

I imagine the temperature parameter is the closest thing we have to that right now. Turn it up a little to make things a bit more creative. Turn it up more and eventually it will wildly swing around in its dialogue. Even more and it eventua

Making it suitable for embedding in other applications (think: electron but with servo, render engine for web scrapers, etc.) seems like a good place to gain a foothold. I’d wager they’re not far from that.

Deleted from your file system but the bits weren’t zeroed on disk. Occasionally your brain reads a random sector.

TIL about Chaitin’s constant. As presented here it seems not well defined, in that it would have to be with reference to some specific instruction set. Guess I have some more reading to do!

Good catch! I saw the “donate” link and assumed whoever made the site was using it for funding. All the better!

I love this. The web used to be a place filled to the brim with people making sites about stuff dedicated to some niche thing that brought them joy. Glad to see that vibe still survives out there. Edit: to be clear, this site is connected w

It explains why the result is the particular value it is, which depends on the date serial number mechanism Excel uses and the mistaken 1900 leap year. I learned something, personally. Also, WRT the idea that “everyone knows” Excel will tre

Certainly not possible in all domains but equally certainly possible in some. There’s not much controversy about the height of the Eiffel Tower or how to concatenate two numpy arrays.

I don’t buy Lecun’s argument. Once you get good RL going (as we are now seeing with reasoning models) you can give the model a reward function that rewards a correct answer most highly, an “I’m sorry but I don’t know” less highly than that,

There are probably pieces of code that are dead but nobody knows they’re dead and the reason they’re dead is not discoverable by static analysis. Like junk DNA, just relics of a bygone past being carried needlessly into the future…

Agreed that (a) it’s not a browser and (b) it’s not ready for prime time. In the meantime it’s great that there is a diversity of options. But I am glad there are new engines being worked on in the wings, and I think servo has potential to

One difference with food delivery/ride share: those can only have costs reduced so far. You can only pick up groceries and drive from A to B so quickly. And you can only push the wages down so far before you lose your gig workers. Wher

In terms of a compromise being “all or nothing,” most secure accounts should have a password (which you can manage in BitWarden) AND a second factor (ideally not tied to your phone; ex: a YubiKey). That way even in the nightmare scenario th

The point is that this is not discussing a physically realizable situation, but an idealized one. The engineering and manufacturing precision that would be required to actually achieve this setup are infinite and unattainable. In the ideali
