- Abstract: Recent years have witnessed significant progress in person re-identification
(ReID). However, current ReID approaches suffer from considerable performance
degradation when the test target domains exhibit different characteristics from
the training ones, known as the domain shift problem. To make ReID more
practical and generalizable, we formulate person re-identification as a Domain
Generalization (DG) problem and propose a novel training framework, named
Multiple Domain Experts Collaborative Learning (MD-ExCo). Specifically, the
MD-ExCo consists of a universal expert and several domain experts. Each domain
expert focuses on learning from a specific domain, and periodically
communicates with other domain experts to regulate its learning strategy in the
meta-learning manner to avoid overfitting. Besides, the universal expert
gathers knowledge from the domain experts, and also provides supervision to
them as feedback. Extensive experiments on DG-ReID benchmarks show that our
MD-ExCo outperforms the state-of-the-art methods by a large margin, showing its
ability to improve the generalization capability of the ReID models.

Domain generalization (DG) has attracted much attention in person re-identification (ReID) recently.
Existing methods usually need the source domains to be labeled, which could be a significant burden for practical ReID tasks.
