A simple neural network implementation which you can train easily.
To try this you must set --experimental-modules argument to node.
Two examples
xor.mjs
Teaches the NN to XOR. The input is an array of two bits, the output Neuron will converge to the right answer:P
characterClassifier.mjs
You tell the NN which character is a number, consonant or a vowel, then it tries to guess it. There are 3 Neurons at the output, each of them contains the chance for that particular type.
Reference implementation Yes, I stole it from there:P
