Interesting but how is a NN necessary instead of examining pixel values?

Good stuff.<p>quick q: why do you call this a hopfield network? I see you have a fully connected 2 layer neural network (0 hidden layers): <a href="https://github.com/mateogianolio/hopfield-color-recognition/blob/master/network.js#L5" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mateogianolio&#x2F;hopfield-color-recognition&#x2F;...</a><p>instead of a bunch of circularly connected perceptrons: <a href="http://en.wikipedia.org/wiki/Hopfield_network#mediaviewer/File:Hopfield-net.png" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hopfield_network#mediaviewer&#x2F;Fi...</a><p>p.s. it looks like the library you&#x27;re using has a built in Hopfield network `new Architect.Hopfield(10)` (at the bottom: [here](<a href="https://www.npmjs.com/package/synaptic)" rel="nofollow">https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;synaptic)</a>), why didn&#x27;t you use this?

I don&#x27;t get it. If you trained to recognize black and white, why did it find such a complex pattern where there were clearly none in the first example? Isn&#x27;t it an example that it failed?

Is the purpose of this project to simulate color perception paradox ( blue or gold dress) ?
