Computer Graphics in the Age of AI and Big Data
Richard (Hao) Zhang,
Simon Fraser University –
Computer graphics is traditionally defined as a field which covers all aspects of computer-assisted image synthesis. An introductory class to graphics mainly teaches how to turn an explicit model description including geometric and photometric attributes into one or more images. Under this classical and arguably narrow definition, computer graphics corresponds to a “forward” (synthesis) problem, which is in contrast to computer vision, which traditionally battles with the inverse (analysis) problem.
In this talk, I would offer my view of what the NEW computer graphics is, especially in the current age of machine learning and data-driven computing. I will first remind ourselves several well-known data challenges that are unique to graphics problems. Then, by altering the above classical definition of computer graphics, perhaps only slightly, I show that to do the synthesis right, one has to first “understand’’ the task and solve various inverse problems. In this sense, graphics and vision are converging, with data and learning playing key roles in both fields.
A recurring challenge, however, is a general lack of “Big 3D Data”, which graphics research is expected to address. I will show you a quick sampler of our recent works on data-driven and learning-based syntheses of 3D shapes and virtual scenes. Finally, I want to explore a new perspective for the synthesis problem to mimic a higher-level human capability than pattern recognition and understanding.
Hao (Richard) Zhang is a professor in the School of Computing Science at Simon Fraser University (SFU), Canada, where he directs the computer graphics (GrUVi) lab and the Professional Masters Program in Visual Computing. He obtained his Ph.D. from the University of Toronto and MMath and BMath degrees from the University of Waterloo. Richard’s research is in computer graphics with special interests in geometric modeling, shape analysis, 3D content creation, as well as computational design and fabrication. He was a past editor-in-chief of Computer Graphics Forum, a SIGGRAPH Asia 2014 course chair, and paper chairs for SGP 2013, Graphics Interface 2015, CGI 2018, among others. He received a National Science and Engineering Research Council of Canada Discovery Accelerator Award in 2014, best paper awards from SGP 2008 and CAD/Graphics 2017, a Faculty Research Excellence Award at SFU in 2014, and a National Science Foundation of China (NSFC) Outstanding Overseas Scholar Award in 2015. He has been a visiting professor at Stanford University, Shandong University, and Shenzhen University.

Research data repositories and tools for human genomics data sharing
Inform the human research community of the status and availability of BioData.pt Local EGA and discuss its need and usability challenges.
The European Genome-phenome Archive (EGA) is a repository for all sequence and genotype experiment types, including case-control, population, and family studies. The EGA will serve as a permanent archive that will archive several levels of data, including the raw data (which could, for example, be re-analysed in the future by other algorithms) as well as the genotype calls provided by the submitters.
Responding to national regulations over human data sharing and other constraints, BioData.pt deploys and operates a Local EGA instance and tools that allow data discovery of genomic and phenoclinic data, following the GA4GH standard and international best practices.
This workshop aims at informing the human research community of the status and availability of BioData.pt Local EGA and discuss from several perspectives its need and usability challenges.

The 13th Lisbon Machine Learning School | LxMLS 2023
The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)
The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
