is_legal_vector()

Check whether the given value is a legal value for the vector representation of this hyperparameter.

Parameters:

value – the vector value to check

Returns:

True if the given value is a legal vector value, otherwise False

Return type:

bool

pdf()

Computes the probability density function of the parameter in the original parameter space (the one specified by the user). For each hyperparameter type, there is also a method _pdf which operates on the transformed (and possibly normalized) parameter space. Only legal values return a positive probability density, otherwise zero.

Parameters:

vector (np.ndarray) – the (N, ) vector of inputs for which the probability density function is to be computed.

Returns:

Probability density values of the input vector

Return type:

np.ndarray(N, )

rvs()

scipy compatibility wrapper for _sample, allowing the hyperparameter to be used in sklearn API hyperparameter searchers, eg. GridSearchCV.
