Query: Joint Optimization in Edge-Cloud Continuum for Federated Unsupervised
  Person Re-identification   Person re-identification (ReID) aims to re-identify a person from
non-overlapping camera views. Since person ReID data contains sensitive
personal information, researchers have adopted federated learning, an emerging
distributed training method, to mitigate the privacy leakage risks. However,
existing studies rely on data labels that are laborious and time-consuming to
obtain. We present FedUReID, a federated unsupervised person ReID system to
learn person ReID models without any labels while preserving privacy. FedUReID
enables in-situ model training on edges with unlabeled data. A cloud server
aggregates models from edges instead of centralizing raw data to preserve data
privacy. Moreover, to tackle the problem that edges vary in data volumes and
distributions, we personalize training in edges with joint optimization of
cloud and edge. Specifically, we propose personalized epoch to reassign
computation throughout training, personalized clustering to iteratively predict
suitable labels for unlabeled data, and personalized update to adapt the server
aggregated model to each edge. Extensive experiments on eight person ReID
datasets demonstrate that FedUReID not only achieves higher accuracy but also
reduces computation cost by 29%. Our FedUReID system with the joint
optimization will shed light on implementing federated learning to more
multimedia tasks without data labels.
