evalml.tuners.GridSearchTuner

class evalml.tuners.GridSearchTuner(pipeline_hyperparameter_ranges, n_points=10, random_state=None, random_seed=0)

Grid Search Optimizer.

Example

>>> tuner = GridSearchTuner({'My Component': {'param a': [0.0, 10.0], 'param b': ['a', 'b', 'c']}}, n_points=5)
>>> proposal = tuner.propose()
>>> assert proposal.keys() == {'My Component'}
>>> assert proposal['My Component'] == {'param a': 0.0, 'param b': 'a'}

Methods

add	Not applicable to grid search tuner as generated parameters are not dependent on scores of previous parameters.
is_search_space_exhausted	Checks if it is possible to generate a set of valid parameters.
