Automatic K-Means H2O

Source: R/auto-kmeans-predict.R
hai_kmeans_automl_predict.Rd

This is a wrapper around the h2o::h2o.predict() function that will return a list object with a lot of useful and easy to use tidy style information.

Usage

hai_kmeans_automl_predict(.input)

Arguments

.input

This is the output of the hai_kmeans_automl() function.

Value

A list object

Details

This function will internally take in the output assigned from the hai_kmeans_automl() function only and return a list of useful information. The items that are returned are as follows:

  1. prediction - The h2o dataframe of predictions

  2. prediction_tbl - The h2o predictions in tibble format

  3. valid_tbl - The validation data in tibble format

  4. pred_full_tbl - The entire validation set with the predictions attached using base::cbind(). The predictions are in a column called predicted_cluster and are in the formate of a factor using forcats::as_factor()
