// Requires: http://cloud.github.com/downloads/harthur/brain/brain-0.6.0.js | |
// Contrived example using string "0" as output. | |
var net = new brain.NeuralNetwork(); | |
net.train([{input: [0, 0], output: {"F":1}}, | |
{input: [0, 1], output: {"1":1}}, | |
{input: [1, 0], output: {"1":1}}, | |
{input: [1, 1], output: {"0":1}}]); | |
var expected = net.run([1, 0]); // {"0":0.044832217084211604,"1":0.8987734592394667,"F":0.03189275580772041} | |
// toFunction works normally. | |
var runner = net.toFunction() | |
JSON.stringify(runner([1,0])) === JSON.stringify(expected) | |
// true | |
// Having a "0" as output causes results of `run` to be converted to an Array when using fromJSON | |
var net_clone = new brain.NeuralNetwork; | |
net_clone.fromJSON(net.toJSON()) | |
JSON.stringify(net_clone.run([1,0])) | |
// "[0.03928773934418956,0.8975583923207543,0.03358100452772138]" | |
JSON.stringify(net_clone.run([1,0])) == JSON.stringify(expected) | |
// false!!! | |
// Work-around: if we use "00" or "#0" or letter "0" instead of number "0" in the output, it works normally. |
