metachirality on metachirality's Shortform

I wish I could bookmark comments/shortform posts.

daemonicsigil on Explaining a Math Magic Trick

Heh, sure.

Promote from a function to a linear operator on the space of functions, $F$ . The action of this operator is just "multiply by $f$ ". We'll similarly define $F^{\sim}, F^{\sim^{2}}$ meaning to multiply by the first, second integral of $f$ , etc.

Observe:

$I F = F^{\sim} - I F^{\sim} D$

$I F = F^{\sim} - F^{\sim^{2}} D + F^{\sim^{3}} D^{2} - \dots$

Now we can calculate what we get when applying $k$ times. The calculation simplifies when we note that all terms are of the form $F^{\sim^{a}} (- D)^{(a - k)}$ . Result:

$I^{k} F = \infty \sum j = k (\frac{j - 1}{k - 1}) F^{\sim^{j}} (- D)^{j - k}$

Now we apply the above operator to $p$ :

$I^{k} F p = \infty \sum j = k (\frac{j - 1}{k - 1}) F^{\sim^{j}} (- D)^{j - k} p$

$I^{k} (f p) = \infty \sum j = k (\frac{j - 1}{k - 1}) (I^{j} f) (- D)^{j - k} p$

The sum terminates because a polynomial can only have finitely many derivatives.

wei-dai on How do open AI models affect incentive to race?

A government might model the situation as something like "the first country/coalition to open up an AI capabilities gap of size X versus everyone else wins" because it can then easily win a tech/cultural/memetic/military/economic competition against everyone else and take over the world. (Or a fuzzy version of this to take into account various uncertainties.) Seems like a very different kind of utility function.

seth-herd on AXRP Episode 31 - Singular Learning Theory with Daniel Murfet

Please just wait until you have the podcast link to post these to LW? We probably don't want to read it if you went to the trouble of making a podcast.

This is now available as a podcast if you search. I don't have the RSS feed link handy.

chris_leong on Does reducing the amount of RL for a given capability level make AI safer?

You mention that society may do too little of the safer types of RL. Can you clarify what you mean by this?

t3t on How do open AI models affect incentive to race?

Yeah, there needs to be something like a nonlinearity somewhere. (Or just preference inconsistency, which humans are known for, to say nothing of larger organizations.)

chris_leong on How do open AI models affect incentive to race?

This fails to account for one very important psychological fact: the population of startup founders who get a company off the ground is very heavily biased toward people who strongly believe in their ability to succeed. So it'll take quite a while for "it'll be hard to make money" to flow through and slow down training. And, in the mean time, it'll be acceleratory from pushing companies to stay ahead.

You can plug it into the Wayback Machine.

jessica-liu-taylor on How do open AI models affect incentive to race?

For corporations I assume their revenue is proportional to f(y) - f(x) where y is cost of their model and x is cost of open source model. Do you think governments would have a substantially different utility function from that?

wei-dai on How do open AI models affect incentive to race?

Hmm, open models make it easier for a corporation to train closed models, but also make that activity less profitable, whereas for a government the latter consideration doesn't apply or has much less weight, so it seems much clearer that open models increase overall incentive for AI race between nations.
