Help on Hopfield Neural Network - gabrielw6 - Jan-08-2017
Hi all,
I've been working on making a python script for a Hopfield Network for the resolution of the shortest path problem, and I have found no success until now. It has been weeks or so that I am banging my head on the keyboard and no solution yet. I have based my efforts until now on two papers I've read - h ttps://www.justbeamit.com/5g3g4 - in which both had simulations of the network through software instead of hardware. Although I have rewritten my code almost a thousand times, I can't find what is going wrong with it; the outputs of the neurons are always far from anything reasonable and correct.
To have some background, just read one of the articles, they aren't big; essentially, I want to find the shortest distance between any two given nodes in a directed graph (not between every node, as in the travelling salesman problem). That will happen when the network minimizes the energy function, like any other Hopfield ANN.

If any of you who has some experience on neural networks can shed some light upon this, I'd be really thankful. I am developing a project that needs it, and my time is almost up.
Thanks in advance.

Here's a couple of pages of references:

(There are at least 10 references here)
