Re: [FRIAM] links for this morning's FRIAM: Special Unitary Groups and Quaternions

I think that's the same as when I said "I knew how to solve n-body systems with particle N^2/2 forces (corrected) with some quadtree or octree optimizations to get from n^2 to nlog(n)." . Or are you saying something different? On Fri, May 5, 2023 at 2:58 PM Angel Edward wrote: > Here’s another

Re: [FRIAM] links for this morning's FRIAM: Special Unitary Groups and Quaternions

Here’s another connection I had forgotten. Consider particles on a 2D rectangle with 1/r^2 repulsion. If you break up the rectangle into smaller rectangles in which particles can only stay in their own rectangles or move to neighbor rectangles, the N^2 force calculation comes down to N log N, s

In celebration of my new found understanding of the Kronecker operator and FFTs with Laplacians, I asked GPT's help to pen some verse as a bard might for a court :-) For context, a couple weeks ago, Frank gave me a ride to Friam with my volvo in the shop. this week I returned his coffee mug he lef

Re: [FRIAM] links for this morning's FRIAM: Special Unitary Groups and Quaternions

Thanks Roger and Ed! I've spent some time with Ed and Frank discussing this and I've really filled in some gaps in my knowledge of parallel algorithms. eg, I knew how to solve n-body system with particle N^2/2 focus with some quadtree or octree optimizations to get from n^2 to nlog(n). But the FFT

Ah, found the RSS feed that sends text around the paywall. -- rec -- I met Geoffrey Hinton at his house on a pretty street in north London just four days before the bombshell announcement that he is quitting Google. Hinton is a pioneer of deep learning
