Query: Mind Your Clever Neighbours: Unsupervised Person Re-identification via
  Adaptive Clustering Relationship Modeling   Unsupervised person re-identification (Re-ID) attracts increasing attention
due to its potential to resolve the scalability problem of supervised Re-ID
models. Most existing unsupervised methods adopt an iterative clustering
mechanism, where the network was trained based on pseudo labels generated by
unsupervised clustering. However, clustering errors are inevitable. To generate
high-quality pseudo-labels and mitigate the impact of clustering errors, we
propose a novel clustering relationship modeling framework for unsupervised
person Re-ID. Specifically, before clustering, the relation between unlabeled
images is explored based on a graph correlation learning (GCL) module and the
refined features are then used for clustering to generate high-quality
pseudo-labels.Thus, GCL adaptively mines the relationship between samples in a
mini-batch to reduce the impact of abnormal clustering when training. To train
the network more effectively, we further propose a selective contrastive
learning (SCL) method with a selective memory bank update policy. Extensive
experiments demonstrate that our method shows much better results than most
state-of-the-art unsupervised methods on Market1501, DukeMTMC-reID and MSMT17
datasets. We will release the code for model reproduction.
