Classifier

var jubatus = require("jubatus"),
    classifier = new jubatus.classifier.client.Classifier(9199, "localhost");

Train

var stringValues = [ ["foo", "bar"] ],
    numValues = [ ["quux", 0.1] ],
    datum = [stringValues, numValues],
    label = "baz",
    data = [ [label, datum] ];

classifier.train(data).then(([ result ] ) => {
    console.error(result);
}).catch(error => {
    console.error(error);
});

Classify

var stringValues = [ ["foo", "qux"] ],
    numValues = [ ["quux", 1] ],
    datum = [stringValues, numValues],
    data = [datum];

classifier.classify(data).then(([ result ] ) => {
    result.forEach(estimateResults => {
        var mostLikely = estimateResults
                .map(([ label, score ]) =>({ label, score })
                .reduce((previous, current) => {
                    return previous.score > current.score ? previous : current;
                }, { label: null, score: NaN });
        console.log("estimate = %j", mostLikely);
    });
}).catch(error => {
    console.error(error);
});
