I don't mean to reduce the work of whichever researchers published in 1983 (are you thinking of Rumelhart et al 1986?), but gradient descent and reverse mode automatic differentiation are way older than 1983. Adaptive filters were bein

Have you considered automating this? Something like a "previous discussions" link?

There's also a book version, which is also quite good.

I would advise standing in the back of a university lecture hall so you can learn just how rare your "not everyone" is.

Yup. It's unfortunate that I can't get security patches. I'm not willing to update to iOS 76 to get the fixes because I don't want to run code that is tested on an A12 on my 5 year old phone, and I don't want to buy

Then ship security updates independently of bells and whistles updates that make old phones dog slow?

Lots of statements about performance, with no benchmarks or numbers. If I've learned one thing about performance optimization, it's that what's obviously faster is frequently slower (unless cache behavior, ILP, etc is obvious

If a future referendum indicated that there was no longer support for leaving the EU, then yes, the government would not be in a position where it needed to take further action - call that "treating it as final" if you wish. Of co

This would make a lot of sense if it wasn't the Saudi government that did it. The Saudi government killing him in their own consulate is not "an attack on the nation."

It's always been interesting to me that both Galois and Abel accomplished so much despite dying so young. Most introductions to Galois theory that I've read have mentioned his duel.

> oppressive regime of Germany, France, and the EU bureaucrats. I'd like to understand what you are talking about. Could you give some more details on this "oppressive regime?"

by twtw 8y ago
Yes, as it was a nonbinding referendum to see if there was support for leaving the EU, come up with a report showing some numbers that indicate the estimated impact and run the whole thing again.

It used to be common in hard sciences and mathematics for English-speaking doctoral candidates to be required to show some aptitude for German or Russian. Maybe still is, dunno.

I don't know, but here are my ideas: - quaternions maybe have a more interesting backstory than other constructs. Not everything was carved into stone. - quaternions never really became part of mainstream mathematical education. This m
