This is the figure given by the question.
Here is the redraw of above circuit.
What I request to ask are:
1. Is my redraw is correct or not?
2. The Vout asked in the question is referred to the voltage after passing throgh R8?
Thank you for your answers.
Why do almost all people not think that neural networks are the mathematical model of intelligence?
I briefly explain what I understand:
-A neuron is a mathematical object that takes numerical inputs from other nearby neurons, applies a nonlinear function (combining the input with numbers...
Hello,
I have a question about the use of functions and overall creation of neural networks in the Wolfram Mathematica (WM) program. I wonder if it is realistic to make meaningful neural networks usable at least partially for scientific research in WM? By scientific research, I do not mean the...
Hi Pfs
Rovelli defines spin networks in this paper
https://arxiv.org/abs/1004.1780
for a trivalent node Vn = 0 (the volume)
nodes begin to "get" volume with the four valent case.
take a cube or a tetrahedron, each vertex is linkes to 3 nodes so they would have a null volume.
things are...
Hi Pfs
My question is not technical. I found papers about recoupling theories about spin networks.
i see what they are about but why this word "recoupling"?
Was there before a decoupling and recoupling whar?
Hi Pfs
Spin networks are defined by the way their links and their nodes are equipped with SU(2) representations and intertwiners.
Could you give an example of two different spin networks with the same number of nodes, links between them, the same coloring of the links (and their orientations)...
Hi Pfs
i found a paper:
https://arxiv.org/abs/math-ph/0306059
in which the author gives a definition of spin networks
it is at the bottom of page 5
the words node or vertex does not appear.
what do you think of it?
Does the author think that all the information is in the hilbert spaces on which...

I'm looking for literature recommendations regarding tensor networks. I never came across singular value decomposition or spectral decomposition in my linear algebra classes, so I need to brush up on the relevant mathematical background as well.
These days most measurement instruments in m,y lab are controlled via an ethernet connection.
In my lab the PCs that control the experiments therefore have two network cards: one is used of "normal" internet/intranet access the other is set to static IP address (typically 192.168.0.x) and is...

Good afternoon,

Neural networks have come a long way since I first took a course, 25 years ago. Now that I'm in the Online Masters in Analytics program at Georgia Tech, I see these topics come up often. I found the following article an interesting read...
Let's say you've trained a neural network and it can classify cat images with good (90%) accuracy.
Now let's say you use a genetic algorithm and start 'breeding' images together using the NN classifier as the fitness function.
Will you eventually start generating pictures that look like cats?

Hi. First of all, I am a beginner when it comes to NN and GA. I have a good enough math background though. Could anyone suggest me a good book that covers these topics in an intermediate level? Obviously a very in-depth coverage is hard to expect but I would like something more than a few pages...
