SDM'19 Workshop on
Deep Learning for Graphs
Graphs (a.k.a., networks) are the universal data structures for representing the relationships between interconnected objects. They are ubiquitous in a variety of disciplines and domains ranging from computer science, social science, economics, medicine, to bioinformatics. Representative examples of real-world graphs include social networks, knowledge graph, protein-protein interaction graphs, and molecular structures. Graph analysis techniques can be used for a variety of applications such as recommending friends to users in a social network, predicting the roles of proteins in a protein-protein interaction network, and predicting the properties of molecule structures for discovering new drugs.
One of the most fundamental challenges of analyzing graphs is effectively representing graphs, which largely determines the performance of many follow-up tasks. This workshop aims to discuss the latest progress on graph representation learning and their applications in different fields. We aim to bring researchers from different communities such as machine learning, network science, natural language understanding, recommender systems, drug discovery. We specially invite submissions related to toolkits and frameworks which make it easy to apply deep learning on graphs. The topics of interest include but are not limited to:
- Unsupervised node representation learning

Dr. Srinivasan Parthasarathy - Benchmarking Graph Representation Learning Methods on Two Tasks: Insights and Renewed Bearing
Abstract (from the speaker): In this talk I will discuss an ongoing effort to benchmark popular graph representation learning methods on a range of datasets on both node classification and link prediction. Our survey covers 12 popular algorithms and 14 datasets. For both tasks we also develop a heuristic (without using representational learning) approach that serves as in important baseline (drawn from task-specific advances). Initial results suggest that classical methods (e.g. Laplacian Eigenmaps) and simple baseline heuristics offer competitive performance on certain types of datasets. We also find that if memory is not an issue - methods based on matrix factorization appear to offer an advantage over random-walk based methods. We conclude with a set of open questions and ideas. This is a joint work with S. Gurukar, P. Vijayan, B. Ravindran and others.

Dr Danai Koutra - Pocket-size structural embeddings in large-scale networks
Abstract (from the speaker) : Networks naturally capture a host of real-world interactions, from social interactions and email communication to web browsing to brain activity. Over the past few years, representation learning over networks has been shown to be successful in a variety of downstream tasks, such as classification, link prediction, and visualization. Most existing approaches seek to learn node representations that capture node proximity. In this talk, I will discuss our recent work on a different class of node representations that aim to preserve the structural similarity between the nodes. I will present the lessons learned from designing efficient structural embedding methods for large-scale heterogeneous data, including ways to overcome the computational challenges and massive storage requirements that many existing techniques face. Throughout the talk, I will discuss applications to professional role discovery, entity resolution, entity linking across data sources, and more.

Dr. Stephan Günnemann - Adversarial Robustness of Machine Learning Models for Graphs
Abstract (from the speaker): Graph neural networks and node embedding techniques have recently achieved impressive results in many graph learning tasks. Despite their proliferation, studies of their robustness properties are still very limited -- yet, in domains where graph learning methods are often used, e.g. the web, adversaries are common. In my talk, I will shed light on the aspect of adversarial robustness for state-of-the art graph-based learning techniques. I will highlight the unique challenges and opportunities that come along with the graph setting and introduce different perturbation approaches showcasing the methods vulnerabilities. I will conclude with a short discussion of methods improving robustness.
