function LivePredictor( model, config ) {

	// "LivePredictor" inherits from abstract predictor "TfjsPredictor".

	TfjsPredictor.call( this, model, config );

	this.predictorType = "LivePredictor";

}
Handle prediction for live model (tfjs model, as only tfjs can train in the browser).
May be there will other training library can run in the browser, so use a new Predictor.
