What is recorded here?
Combined continuous-time invertible dynamics with Hutchinson trace estimation and adjoint-based training to scale log-density evaluation without triangular neural Jacobian restrictions.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Inherits continuous normalizing flows, neural ODEs, adjoints and Hutchinson estimation. Unbiasedness concerns the stochastic log-density integral under stated regularity and exact integration; exponentiation is not thereby an unbiased density estimate and practical ODE solvers introduce numerical error. One-pass sampling is an ODE solve with potentially many function evaluations, not a single network evaluation.
