ML RandomForest - creating Mdl.predict(Vector) from One_hot dataset

2020-04-23 Thread kencottrell
Hello all, I've searched through examples and so far have seen examples on how to do to use one-hot-encoder only for model fitting or for evaluator, but can't figure out how to do this for the predict call. For example, we see use of one-hot as inputs to : 1. RF_MODEL = trainer.fit(

ML Model persist and reuse

2020-01-17 Thread kencottrell
Hello all Apache Ignite ML developers: I understand currently Ignite can't save a model after training, in such a way that the model can be re-imported by another Ignite cluster. Correct me if you can save and reload a model but I don't think you can. Anyway, I'd like to know if you have recomme
