What does RDP order mean?

Gretel uses a variation of differential privacy referred to as Rényi differential privacy (RDP). RDP makes use of the Rényi divergence to measure the distance between distributions. Rényi divergence is a generalization of Kullback-Leibler divergence that works in the notion of a parameter referred to as it’s “order”. In RDP, the idea is to search for the order that optimizes epsilon (e.g. your privacy guarantee). When running Gretel-synthetics, the “optimal RDP order” will be printed along with epsilon and delta once training completes.
