Predictive Rosenblatt Spline offers closed-form inverse for normalizing flows
Algomancer · x · 2026-08-16
Introduces a new bijection for normalizing flows called Predictive Rosenblatt Spline with a closed-form inverse.
- Mechanism: Derives spline knots from posterior prediction over a Gaussian codebook, with all steps being analytic.
- Benefits: Provides exact log-determinant at any K, and zero initialization corresponds to the exact Rosenblatt map.
