Query: Node Classification on Graphs with Few-Shot Novel Labels via Meta
  Transformed Network Embedding   We study the problem of node classification on graphs with few-shot novel
labels, which has two distinctive properties: (1) There are novel labels to
emerge in the graph; (2) The novel labels have only a few representative nodes
for training a classifier. The study of this problem is instructive and
corresponds to many applications such as recommendations for newly formed
groups with only a few users in online social networks. To cope with this
problem, we propose a novel Meta Transformed Network Embedding framework
(MetaTNE), which consists of three modules: (1) A \emph{structural module}
provides each node a latent representation according to the graph structure.
(2) A \emph{meta-learning module} captures the relationships between the graph
structure and the node labels as prior knowledge in a meta-learning manner.
Additionally, we introduce an \emph{embedding transformation function} that
remedies the deficiency of the straightforward use of meta-learning.
Inherently, the meta-learned prior knowledge can be used to facilitate the
learning of few-shot novel labels. (3) An \emph{optimization module} employs a
simple yet effective scheduling strategy to train the above two modules with a
balance between graph structure learning and meta-learning. Experiments on four
real-world datasets show that MetaTNE brings a huge improvement over the
state-of-the-art methods.
