Yeah, I agree. But context is Queen. When the virus is created in the lab, it's done with real stuff distilled from the soupy world. Given enough of a difference in context, the robot may not be able to re-constitute the life because the soupy world surrounding the robot doesn't have the real st

Ha! No, Musk can't have whatever values he has. His values impinge on the world around him. And that impingement will result in a recoil counter-impingement. Our society is still liberal. So such people are allowed a lot of slack. But there is a price to pay somewhere, by someone, for such hubri

It is his behavior that can be influenced, and one way to influence his behavior is through taxation. Trying to persuade him to have different values may or may not be possible. He sort of backed away from Trump after a few interactions. That could be because Trump is crazy or because of

Ok, part of the story is knowing what is really needed for reproducibility as a function of context. With that, then there's the matter of how much control is afforded. Is it programmable in predictable ways? -Original Message- From: Friam On Behalf Of u?l? ?>$ Sent: Wednesday, Novemb

Hey all, Given a square matrix over Z2, how do I find whether or not it is the tensor product of two simpler square matrices? Are there well-known algorithms for deciding this as well as for finding what matrices the original *can be* factored into? [*] Because it is obvious that such factorizati

Sounds like SmartTensors from LANL might be what you want? I’m not sure if that does integers. It focuses only on non-negative I think. From: Friam On Behalf Of Jon Zingale Sent: Wednesday, November 3, 2021 1:13 PM To: friam@redfish.com Subject: [FRIAM] Looking for an algorithm Hey all, Giv

Maybe? As I understand what is typically called matrix decomposition, and tensor decomposition, is something more akin to SVD. I haven't been able to bridge the gap between the two ideas, though it might be my own lack. Anyway, thanks for looking. .-- .- -. - / .- -.-. - .. --- -. ..--.. / -.-. --

Yep. That is what I am talking about. Getting a copy of Van Loan and Golub's classic "Maxtrix Computations" was long overdue, but I finally did it. Between that and the papers cited in my post before, I hope to get a better sense of the problem. .-- .- -. - / .- -.-. - .. --- -. ..--.. / -.-. ---
