Deep Learning for Graphs

ECML-PKDD 2018 Tutorial - 14th September 2018

Organized by:

Davide Bacciu - Università di Pisa (bacciu@di.unipi.it) - Contact person

Alessio Micheli - Università di Pisa (micheli@di.unipi.it)

About

The tutorial will provide an in-depth introduction to the emerging field of deep learning for graphs and to its applications to network data analysis, to bioinformatics, chemistry, physics and vision. Dealing with graph data requires learning models capable of adapting to structured samples of varying size and topology, capturing the relevant structural patterns to perform predictive and explorative tasks while maintaining the efficiency and scalability necessary to process large scale networks.

This tutorial will offer a totally novel perspective on this emerging topic, integrating the latest cutting edge research with foundational works dating back to over 20 years ago and whose knowledge and understanding is currently not widely diffused in the community.

The tutorial is targeted to both early career researchers seeking ideas for their doctoral studies as well as to more advanced stage researchers looking to enter into a lively field of deep learning and seeking both foundational knowledge as well as a perspective on current research.

Outline

The course is organized into two modules. The first module will be devoted to introducing the basic concepts of learning with structured data, followed by a review of the foundational learning models and frameworks for graphs and structured data processing. The second module will build on such foundational concepts to discuss the most recent advances in deep learning for graphs together with their most impacting applications, finally highlighting key open research questions.
