Working with prediction functions in H2O Flow

Now that you finally have a trained model, we can perform predictions on it. Predictions on trained models are straightforward. You just need to load the model and pass in your dataset, which contains the data on which you want to make predictions. H2O will use the loaded model and make predictions for all the values in the dataset. Let’s use the prediction_dataframe.hex dataframe that we created previously to make predictions on.

We will gain an understanding of the prediction operations in the following sub-sections, starting with gaining an understanding of how to make predictions.

Making predictions using H2O Flow

First, let’s start by exploring the Score operation’s drop-down list in the topmost part of the web UI.

You will see a list of scoring operations, as follows:

The preceding drop-down menu shows you a list of all...
