_bases_cosine(X: gpflow.base.TensorType, W: gpflow.base.TensorType, b: gpflow.base.TensorType) → gpflow.base.TensorType[source]#: Feature map for random Fourier features (RFF) as originally prescribed by Rahimi & Recht, 2007 [RR07]. See also [SS15] for additional details.

_bases_concat(X: gpflow.base.TensorType, W: gpflow.base.TensorType) → gpflow.base.TensorType[source]#: Feature map for random Fourier features (RFF) as originally prescribed by Rahimi & Recht, 2007 [RR07]. See also [SS15] for additional details.
