GraphGAN: Graph Representation Learning with Generative Adversarial Nets

22 Nov 2017hwwang55/GraphGAN

The goal of graph representation learning is to embed each vertex in a graph into a low-dimensional vector space. Existing graph representation learning methods can be classified into two categories: generative models that learn the underlying connectivity distribution in the graph, and discriminative models that predict the probability of edge existence between a pair of vertices.

Multi-Task Graph Autoencoders

7 Nov 2018vuptran/graph-representation-learning

We examine two fundamental tasks associated with graph representation learning: link prediction and node classification. We present a new autoencoder architecture capable of learning a joint representation of local graph structure and available node features for the simultaneous multi-task learning of unsupervised link prediction and semi-supervised node classification.

Learning to Make Predictions on Graphs with Autoencoders

23 Feb 2018vuptran/graph-representation-learning

We examine two fundamental tasks associated with graph representation learning: link prediction and semi-supervised node classification. We present a novel autoencoder architecture capable of learning a joint representation of both local graph structure and available node features for the multi-task learning of link prediction and node classification.

dyngraph2vec: Capturing Network Dynamics using Dynamic Graph Representation Learning

7 Sep 2018palash1992/DynamicGEM

Capturing such evolution is key to predicting the properties of unseen networks. We then demonstrate the efficacy of dyngraph2vec over existing state-of-the-art methods on two real world data sets.

Hierarchical Graph Representation Learning with Differentiable Pooling

NeurIPS 2018 RexYing/diffpool

Recently, graph neural networks (GNNs) have revolutionized the field of graph representation learning through effectively learned node embeddings, and achieved state-of-the-art results in tasks such as node classification and link prediction. However, current GNN methods are inherently flat and do not learn hierarchical representations of graphs---a limitation that is especially problematic for the task of graph classification, where the goal is to predict the label associated with an entire graph.

Open Domain Question Answering Using Early Fusion of Knowledge Bases and Text

EMNLP 2018 OceanskySun/GraftNet

In this paper we look at a more practical setting, namely QA over the combination of a KB and entity-linked text, which is appropriate when an incomplete KB is available with a large text corpus. We show that GRAFT-Net is competitive with the state-of-the-art when tested using either KBs or text alone, and vastly outperforms existing methods in the combined setting.

CommunityGAN: Community Detection with Generative Adversarial Nets

20 Jan 2019SamJia/CommunityGAN

In this paper, we propose CommunityGAN, a novel community detection framework that jointly solves overlapping community detection and graph representation learning. First, unlike the embedding of conventional graph representation learning algorithms where the vector entry values have no specific meanings, the embedding of CommunityGAN indicates the membership strength of vertices to communities.

Temporal Graph Offset Reconstruction: Towards Temporally Robust Graph Representation Learning

20 Nov 2018sbonner0/temporal-offset-reconstruction

Graphs are a commonly used construct for representing relationships between elements in complex high dimensional datasets. Many real-world phenomenon are dynamic in nature, meaning that any graph used to represent them is inherently temporal.
