class nessai.flows.fastslowflow.FastSlowFlow(n_fast, n_slow, fast_class, slow_class, joint_class, fast_config=None, slow_config=None)

Bases: nessai.flows.base.BaseFlow

forward(self, x, context=None)

Apply the forward transformation and return samples in the latent space and the log-Jacobian determinant.

Returns

torch.Tensor

Tensor of samples in the latent space

torch.Tensor

Tensor of log determinants of the Jacobian of the forward transformation
