Library for building decision trees with js. Based on ID3 algorithm.

Pretty simple and straightforward to use. Just include the script e.g.

<script type="text/javascript" src="orchid3.min.js"></script>

then you can use factory to build tree

var tree = orchid3.factory(trainingSetAsString, rowsSeparator, valuesSeparator);

To test tree (or rather get decision) use getDecision method

tree.getDecision(sampleData);

Example

var set = 'sunny,hot,high,weak,no;sunny,hot,high,strong,no;overcast,hot,high,weak,yes;',
    test = orchid3.Util.parseData('sunny,hot,high,weak', ';', ','), //or test can already be an array like [['sunny', 'hot', 'high', 'weak']]
    tree = orchid3.factory(set, ';', ',');
tree.getDecision(test); //should return 'no'

See our demo for working, testable example and sample view class for drawing the tree!
