lale.lib.autogen.rbf_sampler module

class lale.lib.autogen.rbf_sampler.RBFSampler(*, gamma=1.0, n_components=100, random_state=None)

Bases: PlannedIndividualOp

Combined schema for expected data and hyperparameters.

This documentation is auto-generated from JSON schemas.

Parameters
  • gamma (float, not for optimizer, default 1.0) – Parameter of RBF kernel: exp(-gamma * x^2)

  • n_components (integer, >=2 for optimizer, <=256 for optimizer, uniform distribution, default 100) – Number of Monte Carlo samples per original feature

  • random_state (union type, not for optimizer, default None) –

    If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random.

    • integer

    • or numpy.random.RandomState

    • or None

fit(X, y=None, **fit_params)

Train the operator.

Note: The fit method is not available until this operator is trainable.

Once this method is available, it will have the following signature:

Parameters

X (array of items : array of items : float) – Training data, where n_samples in the number of samples and n_features is the number of features.

transform(X, y=None)

Transform the data.

Note: The transform method is not available until this operator is trained.

Once this method is available, it will have the following signature:

Parameters

X (array of items : array of items : float) – New data, where n_samples in the number of samples and n_features is the number of features.

Returns

result – Apply the approximate feature map to X.

Return type

array of items : array of items : float
