Hey,

We were using this classifier in our system and since BrainJS is no longer maintained, we ended up writing up the exact same thing using the synaptic package.

If you want to check it out, here it is.

How would this work with huge amount of data (e.g. thousands/millions of pairs), without freezing?

Nice project, btw!

var BrainJSClassifier = require('natural-brain');
var classifier = new BrainJSClassifier();

classifier.addDocument('my unit-tests failed.', 'software');
classifier.addDocument('tried the program, but it was buggy.', 'software');
classifier.addDocument('tomorrow we will do standup.', 'meeting');
classifier.addDocument('the drive has a 2TB capacity.', 'hardware');
classifier.addDocument('i need a new power supply.', 'hardware');
classifier.addDocument('can you play some new music?', 'music');

classifier.train();

////////SERVER METHOD

'sendToServer':function(message){
var classification = classifier.classify(message);
console.log(classification); //=> print classificaiton
return classification; //=> return undefined
}

both natural and brain allow for serialization (in the case of brain), or actual saving of a trained classifer (natural).

Is there a similar functionality here?

Hi,
I clone the repo and did npm install, but then I do npm start I got this:

Hey Man

I am bit confused with the brainjs implementation. If I had to use brain.recurrent.RNN, how can that call be passed whilst adding documents?

If my understanding is correct, this classifier is using node natural only for stemming, stop-words removal right? This is not using the Naive Bayes classifier from the natural library.

Version 3.2.0 of debug was just published.

Hi there,
I'm in love with your natural brain lib.
I think I found a little but critical bug in your code.

I try restore my trained output,
