Classifier

const jubatus = require("jubatus");

const 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) => previous.score > current.score ? previous : current);
        console.log("estimate = %j", mostLikely);
    });
}).catch(error => {
    console.error(error);
});
