Graph meta-learning
Weband language, e.g., [39, 51, 27]. However, meta learning on graphs has received considerably less research attention and has remained a problem beyond the reach of prevailing GNN models. Meta learning on graphs generally refers to a scenario in which a model learns at two levels. In the first level, rapid learning occurs within a task. WebHeterogeneous Graph Contrastive Learning with Meta-path Contexts and Weighted Negative Samples Jianxiang Yu∗ Xiang Li ∗† Abstract Heterogeneous graph contrastive learning has received wide attention recently. Some existing methods use meta-paths, which are sequences of object types that capture semantic re-
