Spectrum-Aware Bounds on Invertibility for Privacy-Enhancing Instance Encoding
A family of new bounds that are tighter, applicable even to fully deterministic encoders, and applicable even to fully deterministic encoders can extend beyond MSE to other norm-based similarity metrics, by properly accounting for the encoder's spectral structure.
