8. Utility functions¶
This is a list of public utility functions. Other functions in this module are meant for internal use.
8.1. use_named_args()
¶
This utility function allows it to use objective functions with named arguments:
>>> # Define the search-space dimensions. They must all have names!
>>> from skopt.space import Real
>>> from skopt.utils import use_named_args
>>> dim1 = Real(name='foo', low=0.0, high=1.0)
>>> dim2 = Real(name='bar', low=0.0, high=1.0)
>>> dim3 = Real(name='baz', low=0.0, high=1.0)
>>>
>>> # Gather the search-space dimensions in a list.
>>> dimensions = [dim1, dim2, dim3]
>>>
>>> # Define the objective function with named arguments
>>> # and use this function-decorator to specify the
>>> # search-space dimensions.
>>> @use_named_args(dimensions=dimensions)
... def my_objective_function(foo, bar, baz):
... return foo ** 2 + bar ** 4 + baz ** 8
8.2. dump()
¶
Store an skopt optimization result into a file.
8.3. load()
¶
Reconstruct a skopt optimization result from a file persisted with dump()
