AWhat changed
Parameterized monotonic rational-quadratic spline transforms inside coupling or autoregressive flows, increasing scalar-transform flexibility while retaining tractable derivatives and analytic inversion.
Scientific scope
Parameterized monotonic rational-quadratic spline transforms inside coupling or autoregressive flows, increasing scalar-transform flexibility while retaining tractable derivatives and analytic inversion. Builds on inherited spline interpolation and preceding spline flows, not invention of all splines. Positive bin widths/heights/derivatives and identity-tail boundary construction enforce the stated transform properties. Analytic inversion does not eliminate autoregressive direction-dependent sampling costs.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
