Regression Test: oldrpf

2025-03-21 16:58:26 UTC

This article serves as a regression test to check the behavior of the current (C++) implementation against the previous “old” implementation, referred to as oldrpf.

Regression

Only supports loss = "L2" and parameters epsilon and delta are not applicable.
