Query: Memorizing Comprehensively to Learn Adaptively: Unsupervised
  Cross-Domain Person Re-ID with Multi-level Memory   Unsupervised cross-domain person re-identification (Re-ID) aims to adapt the
information from the labelled source domain to an unlabelled target domain. Due
to the lack of supervision in the target domain, it is crucial to identify the
underlying similarity-and-dissimilarity relationships among the unlabelled
samples in the target domain. In order to use the whole data relationships
efficiently in mini-batch training, we apply a series of memory modules to
maintain an up-to-date representation of the entire dataset. Unlike the simple
exemplar memory in previous works, we propose a novel multi-level memory
network (MMN) to discover multi-level complementary information in the target
domain, relying on three memory modules, i.e., part-level memory,
instance-level memory, and domain-level memory. The proposed memory modules
store multi-level representations of the target domain, which capture both the
fine-grained differences between images and the global structure for the
holistic target domain. The three memory modules complement each other and
systematically integrate multi-level supervision from bottom to up. Experiments
on three datasets demonstrate that the multi-level memory modules cooperatively
boost the unsupervised cross-domain Re-ID task, and the proposed MMN achieves
competitive results.
