****************************************************** 13th INTERNATIONAL SCHOOL ON DEEP LEARNING DeepLearn 2026 Orléans, France July 20-24, 2026 https://deeplearn.irdta.eu/2026/ ****************************************************** Co-organized by: University of Orléans Centre Val de Loire Doctoral College Institute for Research Development, Training and Advice – IRDTA Luxembourg/London ****************************************************** Early registration: April 25, 2026 ****************************************************** SCOPE: DeepLearn 2026 will be a research training event with a global scope aiming at updating participants on the most recent advances in the critical and fast developing area of deep learning. Previous events were held in Bilbao, Genova, Warsaw, Las Palmas de Gran Canaria, Guimarães, Luleå, Bournemouth, Bari, and Porto. Deep learning is a branch of artificial intelligence covering a spectrum of current frontier research and industrial innovation that provides more efficient algorithms to deal with large-scale data in a huge variety of environments: computer vision, neurosciences, speech recognition, language processing, human-computer interaction, drug discovery, biomedicine and healthcare, medical image analysis, recommender systems, advertising, fraud detection, robotics, games, business and finance, biotechnology, physics and astrophysics, biometrics, communications, climate sciences, geographic information systems, signal processing, genomics, materials design, video technology, social systems, earth and sustainability, mathematical proofs, etc. etc. The field is also raising a number of relevant questions about efficiency and robustness of the algorithms, explainability, transparency, interpretability, risks and safety, as well as important ethical concerns at the frontier of current knowledge that deserve careful multidisciplinary discussion. Most deep learning subareas will be displayed and main challenges identified through 16 four-hour and a half courses, 2 keynote lectures, 1 round table, and a hackathon competition among participants. Renowned academics and industry pioneers will lecture and share their views with the audience. The organizers are convinced that outstanding speakers will attract the brightest and most motivated students. Face to face interaction and networking will be main ingredients of the event. It will be also possible to fully participate in vivo remotely. ADDRESSED TO: Graduates, postgraduates and industry practitioners will be typical profiles of participants. However, there are no formal pre-requisites for attendance in terms of academic degrees, hence people less or more advanced in their career will be welcome as well. Since there will be a variety of levels, specific knowledge background may be assumed for some of the courses. Overall, DeepLearn 2026 is addressed to students, researchers and practitioners who want to keep themselves updated about recent developments and future trends. All will surely find it fruitful to listen to and discuss with major researchers, industry leaders and innovators.

Graph Drawing and Network Visualization are motivated by applications for which it is crucial to visually analyze and interact with relational datasets. Application areas include data science, social sciences, web computing, information systems, life sciences, geography, business intelligence, information security, and software engineering. The International Symposium on Graph Drawing and Network Visualization has been the main annual conference in this area for more than 30 years. Its focus is on combinatorial and algorithmic aspects of graph drawing, their experimental evaluation, as well as the design of network visualization systems and interfaces. Researchers and practitioners working on any aspects of graph drawing and network visualization are invited to contribute papers and posters and to participate in the symposium as well as the graph drawing contest. GD 2026 will be held at Brock University in St. Catharines, Canada, from August 17-21, 2026. A PhD school will take place August 17-18, 2026, followed by a reception on the evening of August 18. GD 2026 is designed to be held on-site. It is expected that regular papers are presented on site by one of the authors. To address global challenges and as an offer for authors who are unable to attend, we allow for a limited number of remote presentations, as further explained below. * * *Important dates*  Abstract Deadline: Wed May 6, 2026 (AoE) Paper (long and short) Deadline: Wed May 13, 2026 (AoE) Paper (long and short) Notification: Wed June 24, 2026 (AoE) Poster Deadline: Wed July 8, 2026 (AoE) Poster Notification: Wed July 22, 2026 (AoE) Camera-ready Version (papers and posters): Wed July 29, 2026 (AoE) Contest Deadline: Wed August 5, 2026 (AoE) PhD School: Mon August 17 – Tue August 18, 2026 Symposium: Wed August 19 – Fri August 21, 2026 *Conferences Nearby in Time and Location* The 38th Canadian Conference on Computational Geometry (_CCCG 2026 <https://sites.google.com/view/cccg-2026/home>_) will be held at Lakehead University’s Orillia Campus in Orillia, Ontario, from August 12 to 14, 2026. * Tracks* We invite authors to submit work describing original research of theoretical or practical significance to graph drawing and network visualization. To promote a balanced coverage of the field, GD has two distinct tracks, and contributions submitted to one track will not compete with contributions submitted to the other track. *Track 1: Combinatorial and algorithmic aspects* This track is mainly devoted to *fundamental theoretical graph drawing advances*, such as combinatorial and algorithmic aspects. We aim at covering a diverse set of topics, which for this track includes (but is not limited to): * Design and analysis of graph drawing algorithms * Geometric and topological graph theory * Computational topology of graphs on surfaces * Graph representations * Geometric advances and computing in graph drawing * Combinatorics and optimization in graph drawing *Track 2: Experimental, applied, and network visualization aspects* This track is mainly devoted to *conceptual and applied aspects of network visualization in the scope of* * graph drawing*, such as experimental evaluations of graph drawing and network visualization related algorithms, the development and/or evaluation of related libraries and tools, or systems and interfaces in different application areas. We aim at covering a diverse set of topics, which for this track includes (but is not limited to): * Engineering of graph drawing algorithms and network visualization approaches * Interfaces, methods, and high-quality tools for interacting with graphs and networks * Benchmarks and experimental studies in the context of graph drawing and network visualization * Cognitive studies on network visualization aesthetics and user interaction * Visualization of networks in real-world applications * Machine learning methods in graph drawing and network visualization * Graph drawing & network visualization for AI explainability and trustworthiness * * *Contribution Types* Perpendicular to the tracks, GD supports three contribution types, as well as a contest. *Long Papers* The standard contribution type is a /long paper/ that describes relevant and original research in full detail. Accepted papers in this category will be assigned a standard time slot for presentation during the conference. *Short Papers* In addition to long papers, there will be a separate category for /short papers/. Here, we welcome smaller and less extensive contributions on relevant topics. Accepted papers in this category will be assigned a shorter time for presentation during the conference. Short papers undergo the same competitive selection process as long papers. *Posters* Finally, we also solicit /poster/ submissions. Accepted posters will be presented in the poster session, and will provide a forum for the communication of late-breaking research results (which may also appear elsewhere) to the GD community. *Contest* The traditional Graph Drawing Contest is held before and during the conference. Details are provided at the _website <https://mozart.diei.unipg.it/gdcontest/2025/>_. Winning submissions will be invited by the contest committee to submit a /contest contribution/, which will appear in the proceedings. * * *Submission Format* The proceedings will be published in the open-access _LIPIcs <https://www.dagstuhl.de/en/publishing/series/details/lipics>_series. To facilitate the process, submissions have to be prepared in accordance with the _LIPIcs author instructions <https://submission.dagstuhl.de/series/details/LIPIcs#author>_. The page provides links to the LIPIcs class file along with an example and detailed author instructions.

These will be formatted as part of the front matter, and not count towards your line limit. Submissions must not exceed the following limits: * 500 lines for long papers, * 250 lines for short papers, * 80 lines for poster abstracts, * 100 lines for contest contributions (by invitation only). The above limits do not include front matter (title, authors, affiliations, classification, etc.), acknowledgements, references, or appendices. The class files provide line counting which should be accurate in most cases. Authors should avoid substantial amounts of text in unnumbered lines. Accepted papers will have additional space to facilitate incorporating reviewer comments. The claims of long and short papers should be fully substantiated. If this information does not fit within the line limit, the authors should include it in a clearly marked appendix, whose length is not constrained and which the reviewers may read at their own discretion. For poster submissions, no appendix is expected. We also encourage authors to avoid "et al." in citations in favor of an equal mention of the surnames of all authors. For references with few authors, it is recommended to name all of them; if the number of authors is large, consider writing "(It is shown that) X [#]" or "The authors in [#] show that X" instead of "A et al. [#] show that X". *Submission Process* Papers should be submitted electronically via _Easychair <https://easychair.org/conferences/?conf=gd2026>_. Authors of posters should prepare an abstract that must be submitted together with the poster itself. Each submission will thus consist of two pdf files (the abstract and the poster). Selected papers from Track 1 and Track 2 will be invited for submission to a special issue of the *Journal of Graph Algorithms and Applications (JGAA)*. The authors of two selected papers in Track 2 will be invited to submit a substantially extended and enhanced version of their work to *IEEE Transactions on Visualization and Computer Graphics (TVCG)*. A special TVCG papers session at the Graph Drawing conference will also feature regular TVCG papers. Further details can be found at _https://www.computer.org/digital-library/journals/tvcg/tvcg-partners-with-… <https://www.computer.org/digital-library/journals/tvcg/tvcg-partners-with-c…>_ * * *Policies* GD implements a number of policies. */AI policy/* Authors are not prohibited from using generative AI (GAI), but are required to be transparent about its use and are responsible for complying with all relevant policies. PC members are prohibited from using GAI during the review process, because submitted manuscripts are confidential and may not be shared with AI platforms. The full AI policy can be found at _http://graphdrawing.org/ai.html <http://graphdrawing.org/safetoc.html>_ */User Study Ethics policy/* If a paper makes use of data from human subjects, the collection and use of such data should have been conducted carefully and should adhere to ethical standards for responsible research practice, as well as data protection regulations. The full ethics policy can be found at _http://graphdrawing.org/userstudies.html <http://graphdrawing.org/safetoc.html>_ */Code of conduct/* GD is dedicated to providing an environment that is free from harassment, bullying, discrimination, and retaliation for all participants, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or technology choices./ / The full code of conduct can be found at _http://graphdrawing.org/safetoc.html <http://graphdrawing.org/safetoc.html>_ * * *MISC TOPICS* *Lightweight Double-Blind Review Process* The review process of long and short papers will be handled in a *lightweight double-blind mode*. This means that authors are not allowed to reveal their identity in the submitted paper, but are free to disseminate draft versions of the paper prior to the conference and to give talks on the topic as they normally would. In particular, the submitted paper should not contain the authors’ names, affiliations, and email addresses. References to their own related work are allowed, as long as the supporting text maintains anonymity (e.g., using sentences in the third person). Members of the Program Committee will not have the identity of the authors of any paper revealed to them during the entire review process. To handle conflicts of interest effectively, authors will be required to declare conflicts of interest with PC members when they submit their paper. Poster submissions will be evaluated by the Program Committee in a *single-blind mode*. In particular, the submitted abstract should contain the authors’ names, affiliations, and email addresses. *Awards* For each of the two tracks, the Program Committee of GD 2026 will bestow a *Best Paper Award*. In addition, to recognize the effort of participants to present their work and to prepare their posters in a clear and elegant way, there will be a *Best Presentation Award *and a *Best Poster Award *voted on by the GD 2026 attendees. Finally, there will be awards for the best submissions in the *Graph Drawing Contest*, decided independently by the Contest Committee. *Remote Presentation* GD 2026 is an in-person meeting. Authors of accepted papers are expected to present their results at the conference. For people who for legitimate reasons cannot participate in person we offer the possibility for remote presentation. To this end, authors may indicate their preference for a remote presentation at the time of submitting their article. Such papers are evaluated and selected by the program committee by applying the same high standards as for the other papers. There is a limit of at most four remote presentations. In case of more requests, decisions may depend on the validity of the reasons mentioned. In all cases, an author of each remote presentation has to register for the conference. *Rules for Submission* Results that have been previously published (or are scheduled for publication) in another conference proceedings or journal, as well as simultaneous submissions of results to other conferences with published proceedings or journals are not permitted, except for poster submissions. With the exception of remote presentations, each paper or poster must be presented at the conference by an author, otherwise the paper can be excluded from publication in the proceedings.
