About
Graph-based data representation allow us to describe both properties and (binary) relationships among different parts of the underlying data, or arrangement of data. Moreover, graphs are not constrained to a fixed size, i.e., the number of nodes and edges is not limited a priori but can be adapted to the size and the complexity of each individual data object. Due to their power and flexibility, graphs have found widespread application in computer science. Prominent examples of data where graphs turn out to be appropriate representation formalisms are, for instance, chemical compounds, text documents, images, source code, protein structures, networks (e.g., it-, social-, or water-networks), and many others.
The overarching goal of the 1st Swiss Symposium on Graph-Based Representation in Computer Science (SympGraph 25) is to bring together PhD students and other interested researchers who are doing some form of research with graphs as the underlying data structure. SympGraph will give participating PhD students a platform to present their current research projects, e.g. in a poster session or in the form of short oral presentations (the form depends strongly on the number of registrations). Each oral presentation is concluded with a moderated question and discussion session. Two talks by renowned experts in the field of graph-based data analysis will frame the general exchange among peers. The symposium will generate new insights for the PhD's own research and - in the best case - the exchange will lead to new collaborations (e.g. exchange of methods, data, or algorithms).

Invited Speakers
Andreas Fischer
Andreas Fischer received the M.S. and Ph.D. degrees in Computer Science from the University of Bern, Switzerland, in 2008 and 2012, respectively. Afterward, he conducted postdoctoral research in Montreal, Canada, at the Centre for Pattern Recognition and Machine Intelligence (CENPARMI) and at Polytechnique Montreal. Currently, he is Full Professor at the University of Applied Sciences and Arts Western Switzerland (HES-SO, HEIA Fribourg) and Lecturer at the University of Fribourg, Switzerland. Andreas Fischer’s research interests include pattern recognition, deep learning, graph-based methods, document analysis, and handwriting recognition. He has published over 100 peer-reviewed articles in international journals and conference proceedings on these topics. Andreas Fischer is a member of the governing board of the International Association of Pattern Recognition (IAPR), where he represents Switzerland, and Chair of the IAPR technical committee on reading systems (TC11).
Benoit Gaüzère
Benoit Gaüzère is an Associate Professor in Machine Learning, conducting research within the LITIS lab and teaching at INSA Rouen Normandie. His work focuses on graph data representation learning and developing machine learning methods for graphs. His recent research explores learning edit costs for graph edit distance, improving pooling layers in Graph Neural Networks (GNNs), and addressing the preimage problem in graph-based models. He actively applies these methods to chemoinformatics. He is involved in multiple research projects, including FAMOUS (fair prediction models, with a focus on graphs), CodeGNN (advancing GNNs by improving convolution, pooling and GNNs on temporal graphs), and AGAC (applying graph-based ML to chemistry). His publications and implementations are available on Google Scholar, HAL, and GitHub.

Registration
To register for the symposium, simply send an email to the organization (kaspar.riesen-at-unibe.ch) until July 15. We ask that you enclose a title for your contribution and a short abstract of your talk (max. 10 sentences) with your written registration.
Participation in SympGraph is free of charge. Students from universities affiliated to the CUSO doctoral program (Universities of Fribourg, Geneva, Lausanne, Neuchâtel and Bern) will have their travel expenses reimbursed (2nd class rail). Furthermore, meals at the venue are free of charge (coffee breaks, sandwich lunch, drinks and a small aperitif at the end of the symposium).
Participation in the SympGraph is also open to PhD students and postdoctoral researchers from non-CUSO universities (however, in this case the travel cost will not be reimbursed).
The number of participants is limited – first come first served (CUSO students have priority in any case).
