Comparison of Affine and Rational Quadratic Spline Coupling and Autoregressive Flows through Robust Statistical Testsstat.ML

This study compares different types of normalizing flows for generating complex distributions.

problem Comparing different types of normalizing flows for generating complex distributions.

method Real-valued non-Volume preserving (RealNVP), masked autoregressive flow (MAF), coupling rational quadratic spline (C-RQS), and autoregressive rational quadratic spline (A-RQS) were compared using statistical tests.

result A-RQS algorithm outperforms others in terms of accuracy and training speed.
