qiskit.aqua.algorithms.QGAN.set_generator

QGAN.set_generator(generator_circuit=None, generator_init_params=None, generator_optimizer=None, generator_gradient=None)

Initialize generator.

Parameters

• generator_circuit (Union[UnivariateVariationalDistribution, MultivariateVariationalDistribution, QuantumCircuit, None]) – parameterized quantum circuit which sets the structure of the quantum generator

• generator_init_params (Optional[ndarray]) – initial parameters for the generator circuit

• generator_optimizer (Optional[Optimizer]) – optimizer to be used for the training of the generator

• generator_gradient (Union[Callable, Gradient, None]) – A Gradient object, or a function returning partial derivatives of the loss function w.r.t. the generator variational params.

Raises

AquaError – invalid input
