Experience levels
When initiating an experiment or prediction, you can define your experience level with data science and machine learning, which defines the settings (hyperparameters) H2O Hydrogen Torch displays for the experiment or prediction you are about to initiate.
Instructions
To define an experience level when starting an experiment or prediction, consider the following instructions:
- On the H2O Hydrogen Torch navigation menu, click Create experiment.
- In the Experience level list, select one of the following experience levels:
- Novice
- Skilled
- Expert
- Master
Grid search enables you to select several values for certain hyperparameters referred to as grid search hyperparameters. To learn more, see Grid search
Grid search
Grid search enables you to select several values for certain hyperparameters referred to as grid search hyperparameters.
Initiating an experiment with grid search results in several experiments where each started experiment through grid search represents one of the combinations of the selected grid search hyperparameter values. After H2O Hydrogen Torch completes all grid search experiments, you can compare and identify ideal hyperparameter values for your experiment (model).
Instructions
To enable grid search when starting an experiment, consider the following instructions:
- On the H2O Hydrogen Torch navigation menu, click Create experiment.
- In the Grid search list, select one of the following grid search modes (options):
- No
- H2O Hydrogen Torch disables grid search.
- Custom grid
- H2O Hydrogen Torch enables grid search, where you can manually select several values for grid search hyperparameters.
- Auto small grid
- H2O Hydrogen Torch enables grid search, where H2O Hydrogen Torch selects several values for certain grid search hyperparameters, where up to 10 experiments are generated when you run (start) the experiment.
- Auto medium grid
- H2O Hydrogen Torch enables grid search, where H2O Hydrogen Torch selects several values for certain grid search hyperparameters, where up to 50 experiments are generated when you run (start) the experiment.
- Auto large grid
- H2O Hydrogen Torch enables grid search, where H2O Hydrogen Torch selects several values for certain grid search hyperparameters, where up to 100 experiments are generated when you run (start) the experiment.
- No
- A grid search hyperparameter assigned several values due to a grid search mode is marked with the following message: H2O Hydrogen Torch has attributed several values to the {grid-search-hyperparameter} due to {grid-search-mode}
- The number of experiments that H2O Hydrogen Torch can generate through grid search might be randomly subsampled based on the computational resources available
- H2O Hydrogen Torch organizes experiments generated from a selected grid search mode into one project
