Maybe we are just quibbling over semantics but the compiler intrinsic here is '__builtin_popcount'. 'stdc_count_ones' is a standard library element that presumably will be implemented using the intrinsic. And FWIW all ma

For pytorch the analogue is Named Tensors, but it's a provisional feature and not supported everywhere. https://docs.pytorch.org/docs/stable/named_tensor.html

That seems uncharitable. I for one enjoy the tidbits he posts in is blog.

Well, actually... the "main" function is handled specially in the standard. It is the only one where the return type is not void and you don't need to explicitly return from it - if you do it, it is treated as if you returned

Those points are true of current AI models, but how sure are you they will remain true as technology evolves? Maybe you believe that they will always stay true, that there's some ineffable human quality that will never be captured by

I can't understand how you reach your conclusion. At present, if you have financial capital and need intellectual capital you need to find people willing to work for you and pay them a lot of money. With enough progress in AI you can g

Actually `e^(sqrt(n) pi)` is very close to being an integer for a couple of different `n`s, including 67 and 163. For 163 it's much closer to an integer, but for 67 you get something you can easily check in double precision floats is c

Charitably it was a joke, as was my quip about `e^(sqrt(67) pi)`. It is a funnier joke without a disclaimer at the end, but unlike GP I couldn't bring myself to leave one out and potentially mislead some people... What I meant was that

Very nice, didn't know about that one! In a similar vein, Ramanujan famously proved that e^(sqrt(67) pi) is an integer. And obviously exp(i pi) is an integer as well, but that's less fun. (Note: only one of the above claims is cor

You make a valid point, but I feel there is something in the direction the article is gesturing at... The mean of the n-dimensional gaussian is an element of R^n, an unbounded space. There's no uninformed prior over this space, so ther

Ditto. I think that ship has sailed, but I think it's unfortunate that "ReLU(x)" became a popular notation for "max(0,x)". And using the name "rectified linear unit" for basically "positive part"

To me it sounded like part of the problem is that people on ECMO cannot leave the ICU because at any moment they might have a complication that requires immediate emergency care. So it's not enough to make them smaller and cheaper, th

I think matplotlib's main strength is its breadth and power. It really lets you do exactly what you want if you spend enough time fiddling and digging through the documentation. All this versatility comes at the expense of ease of use.

I agree that to fully specify electromagnetism you also need to include how the fields affect charged matter. So EM = Maxwell's equations + Lorentz force equation (not sure why you say there is no consensus about what this is, that is

by toth 3y ago
It's true that you can always define notation to combine all equations you want into one. This means that, by itself, the observation that you can write Maxwell's equations as a single equation doesn't say anything very meani

Sorry, but gauge transformations do not (by construction) affect the physical fields at all. You cannot set E to 0, even at a point, with a gauge transformation.

>You can make the electric field disappear by choosing the right gauge. Same goes for the magnetic field (can't make both disappear together though). What? No you can't. The fields are invariant under gauge transformations.

Interesting, I guess that makes sense. Having a quick look at your code, couple of thoughts: - You shouldn't bother with parsing and validating UTF-8. Just pretend it's ASCII. Non ASCII characters are only going to show up in

Hmm, still doesn't seem feasible. Even if you only have 256 "relevant" states (which I think you'll agree is far less than what you need) then given a 32-bit input your state transition table is 2^32*256 = 1 Terabyte. Yo

I deleted two previous comments because I realized I misunderstood your proposal. I understand it better now, but I am still confused about something... Your state machine would need at least 2*160,000 states (you need an extra bit to flag

In general, median and mode are much harder than min/avg/max. You can't compute the former with constant memory in one pass (you can do approximate median, but not exact median). (Here there is a restricted range for the temp
