generate

Tools to facilitate data sample generation.

generate_data(size, kinematics, intensity, phsp_generator=<class 'tensorwaves.data.tf_phasespace.TFPhaseSpaceGenerator'>, random_generator=<class 'tensorwaves.data.tf_phasespace.TFUniformRealNumberGenerator'>, seed=123456.0, bunch_size=50000)

Facade function for creating data samples based on an intensities.

Parameters

• size (int) – Sample size to generate.

• kinematics (HelicityKinematics) – A kinematics instance. Note that this instance must have a property reaction_kinematics_info of the type ParticleReactionKinematicsInfo, otherwise the phase space generator instance cannot be constructed.

• intensity (Function) – The intensity which will be sampled.

• phsp_generator (Callable[[ParticleReactionKinematicsInfo], PhaseSpaceGenerator]) – Class of a phase space generator.

• random_generator (Callable[[float], UniformRealNumberGenerator]) – Class of a uniform real random number generator.

• seed (float) – Used in the random number generation.

• bunch_size (int) – Adjusts size of a bunch. The requested sample size is generated from many smaller samples, aka bunches.

Return type

ndarray
