The upper-right corner of the Driverless AI UI includes an Experiments link.
Click this link to open the Experiments page. From this page, you can rename an experiment, view previous experiments, begin a new experiment, re-run an experiment, and delete an experiment.
An experiment summary is available for each completed experiment. Click the Download Experiment Summary button to download the h2oai_experiment_summary_<experiment>.zip file.
The files within the experiment summary zip provide textual explanations of the graphical representations that are shown on the Driverless AI UI. For example, the preview.txt file provides the same information that was included on the UI before starting the experiment; the summary.txt file provides the same summary that appears in the lower-right portion of the UI for the experiment; the features.txt file provides the relative importance values and descriptions for the top features.
A report file is also included in the experiment summary. This report provides insight into the training data and any detected shifts in distribution, the validation schema selected, model parameter tuning, feature evolution and the final set of features chosen during the experiment. The report is available in PDF format. The report_src.zip file includes the source for this PDF, with the original markdown file and any images that are included in the report.
