class sklearn.gaussian_process.kernels.Hyperparameter
[source] -
A kernel hyperparameter?s specification in form of a namedtuple.
New in version 0.18.
Attributes: name : string
The name of the hyperparameter. Note that a kernel using a hyperparameter with name ?x? must have the attributes self.x and self.x_bounds
value_type : string
The type of the hyperparameter. Currently, only ?numeric? hyperparameters are supported.
bounds : pair of floats >= 0 or ?fixed?
The lower and upper bound on the parameter. If n_elements>1, a pair of 1d array with n_elements each may be given alternatively. If the string ?fixed? is passed as bounds, the hyperparameter?s value cannot be changed.
n_elements : int, default=1
The number of elements of the hyperparameter value. Defaults to 1, which corresponds to a scalar hyperparameter. n_elements > 1 corresponds to a hyperparameter which is vector-valued, such as, e.g., anisotropic length-scales.
fixed : bool, default: None
Whether the value of this hyperparameter is fixed, i.e., cannot be changed during hyperparameter tuning. If None is passed, the ?fixed? is derived based on the given bounds.
