NNP-NET: Accelerating t-SNE Graph Drawing for Very Large Graphs by Neural Networks

Authors: Ilan Hartskeerl, Tamara Mchedlidze, Simon van Wageningen, Peter Vangorp, and Alexandru Telea

Published in: LIPIcs, Volume 357, 33rd International Symposium on Graph Drawing and Network Visualization (GD 2025)

Abstract
tsNET is a recent graph drawing (GD) method that creates high quality layouts but suffers from a very high runtime. We present a new GD method, NNP-NET, which reduces tsNET’s time complexity to generate layouts for very large graphs in seconds. Additionally, we extend tsNET to support drawing graphs with edge weights. We accomplish this by replacing tsNET’s t-SNE projection with Neural Network Projection (NNP), a fast dimensionality reduction (DR) method that can imitate any given DR method. Our experiments show that NNP-NET gets good quality results when compared to other state-of-the art GD methods while yielding a better computational scalability.

BH-tsNET, FIt-tsNET, L-tsNET: Fast tsNET Algorithms for Large Graph Drawing (Poster Abstract)

Authors: Amyra Meidiana, Seok-Hee Hong, and Kwan-Liu Ma

Published in: LIPIcs, Volume 357, 33rd International Symposium on Graph Drawing and Network Visualization (GD 2025)

Abstract
The tsNET algorithm adapts the popular dimensional reduction method t-SNE for graph drawing to compute high-quality drawings, preserving the neighborhood and clustering structure. However, its O(nm) runtime results in poor scalability for large graphs. In this poster, we present three fast algorithms for reducing the time complexity of tsNET to O(n log n) time and O(n) time, by integrating new fast methods for computation of high-dimensional probabilities and entropy computation with fast t-SNE algorithms for computation of KL divergence gradient. Specifically, we present two O(n log n)-time algorithms BH-tsNET and FIt-tsNET, incorporating partial BFS-based high-dimensional probability computation and a new quadtree-based entropy computation with fast t-SNE algorithms, and O(n)-time algorithm L-tsNET, introducing a new fast interpolation-based entropy computation. Extensive experiments using benchmark data sets confirm that BH-tsNET, FIt-tsNET, and L-tsNET outperform tsNET, achieving 93.5%, 96%, and 98.6% faster runtime, respectively, while computing similar quality drawings in terms of quality metrics (neighborhood preservation, stress, shape-based metrics, and edge crossing) and visual comparison.

Stress in Graph Drawings: Perception, Preference, and Performance

Authors: Gavin J. Mooney, Jacob Miller, Michael Wybrow, Stephen Kobourov, and Helen C. Purchase

Published in: LIPIcs, Volume 357, 33rd International Symposium on Graph Drawing and Network Visualization (GD 2025)

Abstract
Stress in a graph drawing has been a popular layout principle for more than two decades. Low stress drawings exhibit the property that the geometric distances between all pairs of nodes correlate with the shortest paths between them. The assumption has always been that low stress drawings are "nicer" and better support human perception and comprehension than high stress drawings. In this paper, we put these assumptions to the test. We use a normalised scale-independent and rotation-independent metric for stress; this is necessary to ensure strict controls on our experimental stimuli. We report on three experiments, exploring human perception of stress, preference for stress, and the effect of stress on a graph performance task. We conclude that people can see stress in a graph drawing, that they prefer low stress drawings, and that their performance in a shortest path task improves as stress decreases - thus empirically confirming long-standing assumptions.

A View on Vulnerabilites: The Security Challenges of XAI (Academic Track)

Authors: Elisabeth Pachl, Fabian Langer, Thora Markert, and Jeanette Miriam Lorenz

Published in: OASIcs, Volume 126, Symposium on Scaling AI Assessments (SAIA 2024)

Abstract
Modern deep learning methods have long been considered as black-boxes due to their opaque decision-making processes. Explainable Artificial Intelligence (XAI), however, has turned the tables: it provides insight into how these models work, promoting transparency that is crucial for accountability. Yet, recent developments in adversarial machine learning have highlighted vulnerabilities in XAI methods, raising concerns about security, reliability and trustworthiness, particularly in sensitive areas like healthcare and autonomous systems. Awareness of the potential risks associated with XAI is needed as its adoption increases, driven in part by the need to enhance compliance to regulations. This survey provides a holistic perspective on the security and safety landscape surrounding XAI, categorizing research on adversarial attacks against XAI and the misuse of explainability to enhance attacks on AI systems, such as evasion and privacy breaches. Our contribution includes identifying current insecurities in XAI and outlining future research directions in adversarial XAI. This work serves as an accessible foundation and outlook to recognize potential research gaps and define future directions. It identifies data modalities, such as time-series or graph data, and XAI methods that have not been extensively investigated for vulnerabilities in current research.

Reproducibility of Data-Oriented Experiments in e-Science (Dagstuhl Seminar 16041)

Authors: Juliana Freire, Norbert Fuhr, and Andreas Rauber

Published in: Dagstuhl Reports, Volume 6, Issue 1 (2016)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 16041 "Reproducibility of Data-Oriented Experiments in e-Science". In many subfields of computer science, experiments play an important role. Besides theoretic properties of algorithms or methods, their effectiveness and performance often can only be validated via experimentation. In most of these cases, the experimental results depend on the input data, settings for input parameters, and potentially on characteristics of the computational environment where the experiments were designed and run. Unfortunately, most computational experiments are specified only informally in papers, where experimental results are briefly described in figure captions; the code that produced the results is seldom available. This has serious implications. Scientific discoveries do not happen in isolation. Important advances are often the result of sequences of smaller, less significant steps. In the absence of results that are fully documented, reproducible, and generalizable, it becomes hard to re-use and extend these results. Besides hindering the ability of others to leverage our work, and consequently limiting the impact of our field, the absence of reproducibility experiments also puts our reputation at stake, since reliability and validity of empiric results are basic scientific principles. This seminar brought together experts from various sub-fields of computer science to create a joint understanding of the problems of reproducibility of experiments, discussing existing solutions and impediments, and proposing ways to overcome current limitations.

Music Information Technology and Professional Stakeholder Audiences: Mind the Adoption Gap

Authors: Cynthia C.S. Liem, Andreas Rauber, Thomas Lidy, Richard Lewis, Christopher Raphael, Joshua D. Reiss, Tim Crawford, and Alan Hanjalic

Published in: Dagstuhl Follow-Ups, Volume 3, Multimodal Music Processing (2012)

Abstract
The academic discipline focusing on the processing and organization of digital music information, commonly known as Music Information Retrieval (MIR), has multidisciplinary roots and interests. Thus, MIR technologies have the potential to have impact across disciplinary boundaries and to enhance the handling of music information in many different user communities. However, in practice, many MIR research agenda items appear to have a hard time leaving the lab in order to be widely adopted by their intended audiences. On one hand, this is because the MIR field still is relatively young, and technologies therefore need to mature. On the other hand, there may be deeper, more fundamental challenges with regard to the user audience. In this contribution, we discuss MIR technology adoption issues that were experienced with professional music stakeholders in audio mixing, performance, musicology and sales industry. Many of these stakeholders have mindsets and priorities that differ considerably from those of most MIR academics, influencing their reception of new MIR technology. We mention the major observed differences and their backgrounds, and argue that these are essential to be taken into account to allow for truly successful cross-disciplinary collaboration and technology adoption in MIR.

10291 Abstracts Collection – Automation in Digital Preservation

Authors: Jean-Pierre Chanod, Vittore Casarosa, Milena Dobreva, Andreas Rauber, and Seamus Ross

Published in: Dagstuhl Seminar Proceedings, Volume 10291, Automation in Digital Preservation (2010)

Abstract
Digital Preservation has evolved into a specialized, interdisciplinary research discipline of its own, seeing significant increases in terms of research capacity, results, but also challenges. However, with this specialization and subsequent formation of a dedicated subgroup of researchers active in this field, limitations of the challenges addressed can be observed. Digital preservation research may seem to react to problems arising, fixing problems that exist now, rather than proactively researching new solutions that may be applicable only after a few years of maturing. Recognising the benefits of bringing together researchers and practitioners with various professional backgrounds related to digital preservation, a seminar was organized in Schloss Dagstuhl, at the Leibniz Center for Informatics (18-23 July 2010), with the aim of addressing the current digital preservation challenges, with a specific focus on the automation aspects in this field. The main goal of the seminar was to outline some research challenges in digital preservation, providing a number of “research questions” that could be immediately tackled, e.g. in Doctoral Thesis. The seminar intended also to highlight the need for the digital preservation community to reach out to IT research and other research communities outside the immediate digital preservation domain, in order to jointly develop solutions.

A Future Emulation and Automation Research Agenda

Authors: Dirk von Suchodoletz

Published in: Dagstuhl Seminar Proceedings, Volume 10291, Automation in Digital Preservation (2010)

Abstract
After significant research and proven usefulness especially for complex, dynamic and interactive objects emulation is not widely adapted in digital preservation at all. While some significant building blocks of emulation based strategies are present a number of components are still unsatisfactory or missing. This paper proposes a research agenda for the future integration of emulation into preservation workflows. It discusses prerequisites and requirements for fully automated services operating in large scale environments. Those include the replacement of user interaction by using a standard interfacing protocol like Virtual Network Computing, proper system image and software components archiving and the ''preservation aware'' emulator. To achieve this additional channels to control the emulator and monitor its states are required. This paper analyses the state of the art in emulation and motivates the need for introducing additional control channels.

Challenges in preservation (planning)

Authors: Christoph Becker

Published in: Dagstuhl Seminar Proceedings, Volume 10291, Automation in Digital Preservation (2010)

Abstract
This short paper attempts to highlight some challenges to be tackled by DP research in the next years, taking as a starting point the perspective of preservation planning. These challenges are in short: (1) Scalability (up and down) requiring (2) measurement of relevant decision factors, in turn requiring (3) benchmarking and ground truth. (4) Quality-aware emulation. (5) Move from the current closed-systems approach to open structures that accomodate evolving knowledge. (6) Move from post-obsolescence actions to 'longevity engineering'.

Collecting Usage Data for Digital Preservation

Authors: Muriel Foulonneau

Published in: Dagstuhl Seminar Proceedings, Volume 10291, Automation in Digital Preservation (2010)

Abstract
While IT environments are moving towards personalized and context-aware adaptive content and services, digital preservation systems should go beyond the current mechanisms to preserve digital objects. Social and personal experiences need to be investigated as part of the context of digital resources, i.e., the way in which a resource was used and perceived, by retaining usage data for instance. Overall, users have to be further involved in the digital preservation processes, in the creation of context metadata, in the storage and migration of resources, in particular for personal archives.

Data, Information, and Knowledge: "where is the Life we have lost in living?"

Authors: Yunhyong Kim

Published in: Dagstuhl Seminar Proceedings, Volume 10291, Automation in Digital Preservation (2010)

Abstract
This abstract attempts to raise the question of whether current practices in digital preservation properly address the issues of findability of digital objects. It is also intended as a starting point for discussing preservation of digital information in contrast to digital data. The abstract is exploratory and informal.
