IntegrandProbability¶
-
class IntegrandProbability : public madspace::FunctionGenerator¶
The sampling density of an Integrand at a given phase-space point.
Evaluates the probability with which the integrand’s adaptive samplers and channel selection would have produced a given point. Used to compute importance weights when replaying stored events.
Arguments
the latent coordinates and discrete indices of a stored point; see Integrand.
Returns
probability–float, shape(batch,)– the sampling density.
