Dear all, Let me introduce the topic first, so this thread can be put in the most appropriate subforum. Belief propagation, also called message passing, is a method that communicates messages between nodes on graphical model (for example a Markov random field) and where the messages...

Yes, I've Matlab. But thanks anyway for your suggestion.

Does anyone know of an online lambda calculator? Or actually I need an online calculator that allows the result to be used in the next calculation. Like the "Ans[wer]" key on some realworld calculators. It allows me to see for myself how for example the Cauchy series "1/Ans + Ans/2" converges...

Maybe it is a good idea to have mathematical tutorials like in the subforum about Physics. I have no homework anymore :smile: but tend to think that doing mathematics is a skill that always pays back at the end. First thing I want to know what https://en.wikipedia.org/wiki/Fisher_information...

Please, can you give me an example! Anti-commutation, Dirac, probability Hi Doctordick, you do have a revealing way of describing things. The way you're talking about it, I "squink" that anti-commutation is a form of symmetry breaking. I read just about Dirac's notation in "The Emperor's New...

The math is not difficult at all... Matrix mechanics Aah. The basic concepts about matrix multiplication etc, I know. I did my bachelor electrical engineering (e.m. waves etc). I'll say it, if something is too difficult for me. I don't know a thing about Heisenberg's matrix mechanics. I forgot...

Introduction concept 'time' Aha, it's that simple! Aha, that makes some things clear. That's straightforward. Yes, that makes sense. Providing the items in reversed order is still in order. Looking forward, :smile: Andy

Derivation Yes, how cool! Using numeric labels, adding as well as multiplying is possible. Adding a number to every label in every B doesn't change the probability P. That's right. P(x1+b, ..., xn+b) should have the same outcome. Differentiating to b (or a) results in zero. I also agree with...

Do you have reasons to suggest that it could have gone in a different way? What possibilities are you talking about? Do you have an infinite amount of possible pasts? What's unique in regard to your consciousness? Some say that's where "end of the tunnel experiences" come from.

A religion it is.

As problem solving your presentation is general enough. However, like somebody pointed out in another thread, considering the problem of the origin of the apparatus that receives and distinguish as such the messages Bj, and that can contain memory (set C), I don't see how it can account for...

Labels Yes, I understand. A message can be a composition/mixture of e.g. {3, red} or {2309.23 €, "bkkkpoi", banana-taste}. To label the elements '3' and 'red' is unwanted and unjustified 'labelism'. The nature of a 'message' Does a message / obervation embed it's whole context {time, place...

Can a moderator move this thread if it's not appropriate here? It's not homework...

Understanding You got me! Sorry! :smile: I've printed your last two posts addressing me. Concreet example I find the concepts of the sets still a bit difficult. Can you give some concrete examples? Can I take 'warmth' - with all kind of properties - as set A? Excuse me for the layman...

Complex Fourier series Another thought. Even the complex Fourier series can be visualized as superimposed circles with different frequencies isn't it? f(t)=\sum_{n=-\infty}^{n=\infty}{A_n \exp{jn\omega_0t}} with A_n the radius of the circle n. Does nobody know of this manner of visualization?
