To address the above limitations, we propose an Unsupervised Domain Adaptive Graph Convolutional Networks (UDA-GCN) for cross-domain node classification by modeling the local and global consistency relationship of each graph, and combining source infor-mation, domain information and target information into a unified deep model.

gorithm without pair-wise labelled data (i.e., unsupervised learning) is a great challenge in recent person RE-ID re-search. There have been a series of unsupervised image based methods to address this problem, which can be roughly divided into three categories: 1) image-to-image trans-lation, 2) domain adaptation, 3) unsupervised clustering.

Unsupervised graph classification/representation learning via distances. This demo demonstrated training a graph classification model without supervision. This model could be used to compute embedding vectors or representations for graphs. The algorithm uses a ground-truth distance between graphs as a metric to train against, by embedding pairs of graphs simultaneously and combining the resulting embedding vectors to match the distance.
