- Abstract: Face recognition has been extensively studied in computer vision and
artificial intelligence communities in recent years. An important issue of face
recognition is data privacy, which receives more and more public concerns. As a
common privacy-preserving technique, Federated Learning is proposed to train a
model cooperatively without sharing data between parties. However, as far as we
know, it has not been successfully applied in face recognition. This paper
proposes a framework named FedFace to innovate federated learning for face
recognition. Specifically, FedFace relies on two major innovative algorithms,
Partially Federated Momentum (PFM) and Federated Validation (FV). PFM locally
applies an estimated equivalent global momentum to approximating the
centralized momentum-SGD efficiently. FV repeatedly searches for better
federated aggregating weightings via testing the aggregated models on some
private validation datasets, which can improve the model's generalization
ability. The ablation study and extensive experiments validate the
effectiveness of the FedFace method and show that it is comparable to or even
better than the centralized baseline in performance.

Hallucination [68.78903256687697]
In Heterogeneous Face Recognition (HFR), the objective is to match faces across two different domains such as visible and thermal.
Recent methods attempting to fill the gap via synthesis have achieved promising results, but their performance is still limited by the scarcity of paired training data.
In this paper, we propose a new face hallucination paradigm for HFR, which not only enables data-efficient synthesis but also allows to scale up model training without breaking any privacy policy.

This work proposes PrivacyFace, a framework to improve federated learning face recognition.
It consists of two components: First, a practical Differentially Private Local Clustering mechanism is proposed to distill sanitized clusters from local class centers.
Second, a consensus-aware recognition loss subsequently encourages global consensuses among clients, which ergo results in more discriminative features.
