Quantifying Training Membership Information in the Hyperspherical Embedding Geometry of Face Recognition Models

Ünsal Öztürk, Sébastien Marcel

Face recognition models represent each face as an embedding vector on the unit hypersphere by clustering embeddings of the same identity while pushing different identities apart th…

Variational Latent Entropy Estimation Disentanglement: Controlled Attribute Leakage for Face Recognition

Ünsal Öztürk, Vedrana Krivokuća Hahn, Sushil Bhattacharjee +1

Face recognition embeddings encode identity, but they also encode other factors such as gender and ethnicity. Depending on how these factors are used by a downstream system, separa…

Deep Privacy Funnel Model: From a Discriminative to a Generative Approach with an Application to Face Recognition

Behrooz Razeghi, Parsa Rahimi, Sébastien Marcel

In this study, we apply the information-theoretic Privacy Funnel (PF) model to face recognition and develop a method for privacy-preserving representation learning within an end-to…
