Calling H2O Algorithms ---------------------- 1. Create the parameters object that holds references to input data and the parameters for the specific algorithm: .. code:: scala val train: RDD = ... val valid: H2OFrame = ... val gbmParams = new GBMParameters() gbmParams._train = train gbmParams._valid = valid gbmParams._response_column = "bikes" gbmParams._ntrees = 500 gbmParams._max_depth = 6 2. Create a model builder: .. code:: scala val gbm = new GBM(gbmParams) 3. Invoke the model build job and block until the end of computation (``trainModel`` is an asynchronous call by default): .. code:: scala val gbmModel = gbm.trainModel.get
