            class: 'positive',
        },
        {
            text: 'this was a great movie',
            class: 'positive',
        },
        {
            text: 'the movie was awesome',
            class: 'positive',
        },
        {
            text: 'I absolutely loved the movie',
            class: 'positive',
        },
        {
            text: 'the movie was pretty bad',
            class: 'positive',
        },
    ],
    test: [
        {
            text: 'it was a good movie',
            class: 'positive',
        },
        {
            text: 'it was bad',
            class: 'negative',
        },
    ],
};

module.exports = data;

train.js

var trainer = require('synaptic-simple-trainer');
var data = require('./data');

trainer.trainData = data.train;
trainer.testData = data.test;

trainer.prepareData();
trainer.run(function() {
    process.exit();
});

test.js

var trainer = require('synaptic-simple-trainer');
var data = require('./data');

trainer.trainData = data.train;
trainer.testData = data.test;

trainer.test();
trainer.completed();

process.exit();

Once everything is ready, just run node example/train.js. After it's run at least once, you'll be able to test it with node example/test.js, because the brain (network) was saved, and will be reused.

For a more detailed example, please view the /example folder.

Note: If you add new words / classes to your trainData (trainingSet), you will need to re-train the network again! In case you have a larger training set, you may not need to re-train (but only, if all the existing words / classes already exist)!
