Introduction

This repo will release the two proposed benchmarks GFR-R and GFR-V in our paper. I hope the proposed benchmarks will attract researchers on Generalized Face Recognition problem. More details can be referred to our paper Learning Meta Face Recognition in Unseen Domains, accepted to CVPR2020.

GFR Problem

What is GFR (Generalized Face Recognition) problem?

In real-world applications of face recognition, the model trained on source domains D_S is usually deployed in another domain D_T with a different distribution. If the target domain D_T is known and the data is accessible, it is categorized into domain adaptation for face recognition. If the target domain is unseen, it can be regarded as domain generalization for face recognition, and we call it Generalized Face Recognition, which is more common as the trained model is usually deployed in unknown scenarios and faced with unseen data. As shown below, the deployed model should be able to generalize to unseen domains without any updating or fine-tuning.

GFR-R and GFR-V Benchmark

GFR-R is for crossing race evaluation and GFR-V is crossing facial variety, which means a large gap between source domains and target unseen domains. The involved datasets and protocols are shown in two tables below.

Our Method

Our proposed method are inspired by MAML, shown in the figure below.

The meta-optimization procedure:
