Query: GCN-LASE: Towards Adequately Incorporating Link Attributes in Graph
  Convolutional Networks   Graph Convolutional Networks (GCNs) have proved to be a most powerful
architecture in aggregating local neighborhood information for individual graph
nodes. Low-rank proximities and node features are successfully leveraged in
existing GCNs, however, attributes that graph links may carry are commonly
ignored, as almost all of these models simplify graph links into binary or
scalar values describing node connectedness. In our paper instead, links are
reverted to hypostatic relationships between entities with descriptional
attributes. We propose GCN-LASE (GCN with Link Attributes and Sampling
Estimation), a novel GCN model taking both node and link attributes as inputs.
To adequately captures the interactions between link and node attributes, their
tensor product is used as neighbor features, based on which we define several
graph kernels and further develop according architectures for LASE. Besides, to
accelerate the training process, the sum of features in entire neighborhoods
are estimated through Monte Carlo method, with novel sampling strategies
designed for LASE to minimize the estimation variance. Our experiments show
that LASE outperforms strong baselines over various graph datasets, and further
experiments corroborate the informativeness of link attributes and our model's
ability of adequately leveraging them.
