Title: AI Preparedness for Cancer Registries

Speaker: Dimitris Katsimpokis, PhD, Netherlands Comprehensive Cancer Organisation (Comprehensive Cancer Organisation of the Netherlands - IKNL)

AbstractGiven the forecasted rise of cancer incidence within the next decades worldwide, AI can be a vital tool to accelerate the work of cancer registries and therefore reduce the impact of cancer. The talk will focus on several on-going projects within IKNL related to AI preparedness and cancer registries: federation, synthetic data, Machine Learning (ML) prediction modelling and Large Language Models (LLMs). Specifically, the talk will outline IKNL’s open-source tool for federated analysis (vantage6) delving into its architecture and analyses. Subsequently, we will focus on aspects of synthetic data generation (e.g., predictive power) used for research purposes by looking at survival classification of lung cancer synthetic data. Then, we will turn to two projects on prediction of time-to-event (survival) modelling, first on ovarian cancer progression-free survival prediction (comparing ML with traditional approaches), and second on training LLMs to predict overall survival in breast cancer synthetic data, the latter being a joint project with the Joint Research Center (JRC) of the European Commission. Lastly, the talk will present recent efforts to create and validate a knowledge-based chatbot helper for AI-assisted cancer registration. In the end, we will discuss the challenges of using AI in a cancer registry setting (e.g., issues related to privacy, infrastructure).

Short BiographyDimitris Katsimpokis, PhD, is a Senior Clinical Data Scientist at the R&D Department of the Comprehensive Cancer Organisation of the Netherlands (IKNL). To support IKNL’s overall goal to reduce the impact of cancer, his research focuses on accelerating the work of the National Cancer Registry (NCR) through the use of AI in various domains: ML-based prediction modelling of cancer survival, synthetic data generation and quality control, as well as cancer knowledge representation with the help of Retrieval Augmented Generation (RAG) and Large Language Models (LLMs).

Apart from AI, his work also includes: causal inference on the role of socio-economic status in accessing expensive lung cancer medication in the Netherlands, forecasting cancer survival in the Netherlands until 2045, developing a Python package for missing value imputation implementing a generalization of the popular MissForest algorithm, as well as developing hierarchical Bayesian models in STAN. His work has been published in Journal of Clinical EpidemiologyQuality of Life Research and Psychonomic Bulletin and Review.

Mission

To build an AI Excellence Hub in Greece where the international research community can connect, groundbreaking ideas can thrive, and the next generation of scientists emerges, shaping a brighter future for Greece and the world

 

Welcome to ARCHIMEDES, a vibrant research hub connecting the global AI and Data Science research community fostering groundbreaking research in Greece and beyond. Its dedicated core team, comprising lead researchers, affiliated researchers, Post-Docs, PhDs and interns, is committed to advancing basic and applied research in Artificial Intelligence and its supporting disciplines, including Algorithms, Statistics, Learning Theory, and Game Theory organized around 8 core research areas. By collaborating with Greek and Foreign Universities and Research Institutes, ARCHIMEDES disseminates its research findings fostering knowledge exchange and providing enriching opportunities for students. Leveraging AI to address real-world challenges, ARCHIMEDES promotes innovation within the Greek ecosystem and extends its societal impact. Established in January 2022, as a research unit of the Athena Research Center with support from the Committee Greece 2021, ARCHIMEDES is funded for its first four years by the EU Recovery and Resilience Facility (RRF).

Archimedes and the Biomedical Research Foundation Share Latest Findings in AI and Medicine

Archimedes and the Biomedical Research Foundation of the Academy of Athens successfully hosted a special collaborative session at the Panhellenic Working Group Seminars of the Hellenic Society of Cardiology. This session focused on innovative applications of artificial intelligence in medicine, with a particular emphasis on advancements in cardiology. Held on Friday, February 7, 2025, in Room MC2 of the Megaron Athens International Conference Centre, the event brought together leading experts to explore how artificial intelligence is transforming cardiovascular medicine.

Archimedes Reaches Milestone of 200 Publications

Archimedes Reaches Milestone of 200 Publications

Archimedes is proud to announce that its researchers have published over 200 scientific publications in top-tier conferences (NeurIPS, ICLR, ICML) and journals.Archimedes maintains a vibrant scientific community of over 130 researchers, including more than 60 senior researchers (faculty members from Greece and abroad), 12 postdoctoral fellows, and 55 PhD students, along with over 20 undergraduate interns from various disciplines.

Happy International Greek Language Day!

Happy International Greek Language Day!

Today, we celebrate the historical, cultural, and linguistic significance of the Greek language. While Standard Modern Greek often takes center stage, we at Archimedes - AI and Data Science Research Hub recognize the impressive diversity and great cultural significance of its numerous dialects. These dialects present both exciting opportunities and complex challenges for AI and Large Language Models (LLMs) because each one of them presents unique linguistic features and all of them are low resourced. That’s why we’re using cutting-edge AI to document, digitize, and analyze these invaluable linguistic treasures, ensuring their preservation and accessibility for generations to come.

 
 

The project “ARCHIMEDES Unit: Research in Artificial Intelligence, Data Science and Algorithms” with code OPS 5154714 is implemented by the National Recovery and Resilience Plan “Greece 2.0” and is funded by the European Union – NextGenerationEU.
