WS 2a (1/2) - Building Agentic ML Tools for Science: What Works and What Doesn’t

Session Chair: Till Korten, Helmholtz Zentrum Dresden Rossendorf (HZDR)
Session Chair: Haider Khan, Helmholtz Zentrum Munich
Brief Description and Outline:\nLarge language models and agentic AI systems are increasingly being adopted as tools in scientific workflows —from literature review and data analysis to experimental design and code generation.\nYet building effective agentic tools for research remains as much craft as science: architectural choices around retrieval strategies, tool-use protocols, embedding models, and human-in-the-loop interfaces can make or break a system’s practical utility. At the same time, the rapid pace of development means that hard-won lessons about what works (and what fails) are rarely shared systematically across projects.\n\nThis workshop brings together developers and users of agentic ML tools for science to openly exchange practical knowledge and experience. Rather than focusing on algorithmic novelty, we emphasize engineering reality: Which design patterns lead to reliable agentic behavior? Where do current LLM-based tools fall short in scientific contexts? How do we evaluate whether an agentic tool genuinely accelerates research or merely creates an illusion of productivity?\n\nAs a basis for discussion, we present concrete example projects that tackle different facets of agentic scientific tooling —from semantic literature exploration with retrieval-augmented generation and clustering MCP tools to machine learning project planning systems. By dissecting these systems in detail, including their failures and limitations, we aim to distill transferable principles for the Community.\n\nThe workshop combines presentation-driven discussion in the morning with hands-on collabora- tive work in the afternoon. Morning sessions feature short project presentations interleaved with structured discussion. The afternoon hackathon lets participants turn ideas into code or concrete plans in small groups. Participants are encouraged to bring their own experiences, tools, and “war stories” to contribute throughout.\n-\nPresentations — Architecture walk-through, live demo, design trade-offs, and lessons learned & Discussion (2 h)\n-\nTime Session\n~30 min Introduction to Agentic AI for Science\n~30 min Project Presentation: Abstracts Explorer\n~30 min Project Presentation: Voucher Canvas Agent\n~15 min Break\n~15 min General Discussion —Cross-cutting themes: What design patterns were transferred? Where did things break? What would we do differently?\n-\nHackathon (2 h)\nParticipants form small groups to build or plan agentic ML tools hands-on. Groups self-organize around topics proposed in the morning discussion. Possible tracks include:\n• Feature sprints —Implement a concrete feature in one of the presented projects (e.g., a new MCP tool, a conference downloader plugin, an improved clustering pipeline). Bring a laptop and be ready to write code.\n• Project planning —Sketch the architecture and roadmap for a new agentic tool addressing a participant’s own research domain. Output: a brief design document or project proposal.\n• Integration experiments —Wire up existing tools via MCP or other protocols and stress-test them with real scientific queries. Time Session ~15 min Group Formation —Pitch topics, form groups (3–5 people). ~90 min Hands-on Work —Small-group hacking / planning with roaming support from organizers. ~15 min Lightning Reports —Each group presents what they built, learned, or planned (~2 min each).\n-\nExample Projects\n\n\nAbstracts Explorer — An open-source Python toolkit combining LLM-based semantic search, unsupervised clustering, and RAG to explore conference proceedings (NeurIPS, ICLR, ICML) at scale. Features native MCP integration for LLM-driven topic and trend analysis, a Flask web interface, and Docker-based deployment. (github.com/thawn/abstracts-explorer)\n\n\nVoucher Canvas Agent — an AI-powered exploration agent designed to help users plan machine learning projects. It uses a multi-container architecture with a LangGraph agent and a custom exploration server\n\n\n-\nGoals:\n• Architecture & Integration: How should agentic tools expose capabilities to LLMs (e.g., via the Model Context Protocol)? What are effective patterns for combining retrieval, structured analysis, and generation?\n• Evaluation & Trust: How do we measure whether an agentic science tool is actually helpful?\nWhen should we trust LLM-generated analyses of scientific literature?\n• Practical Pitfalls: What are common failure modes —hallucinated references, embedding model drift, brittle tool-use chains —and how can they be mitigated?\n• Human-in-the-Loop: What level of autonomy is appropriate? Where must human oversight remain, and how do we design interfaces that support it?\n-\nPresenters Experience:\nTill Korten is a Helmholtz AI Consultant and developer of Abstracts Explorer.\nHaider Khan is a Helmholtz AI Consultant and developer of Voucher Canvas Agent.\n-\nTarget Audience:\nResearchers, research software engineers, and data scientists who are building, evaluating, or considering agentic ML tools in their scientific workflows. No prior experience with agent frameworks is required — practical curiosity and a willingness to share experiences are the main prerequisites. For the afternoon hackathon, a laptop with Python 3.11+ and Git installed is recommended.\n-\nKeywords:\nAgentic AI; scientific workflows; human–AI interaction; evaluation and benchmarking; research infrastructure; AI governance

Brief Description and Outline:\nSimulation-Based Inference (SBI) is rapidly emerging as a powerful paradigm for scientific discovery, enabling parameter estimation, uncertainty quantification, and model selection in complex systems. However, significant challenges remain in translating SBI’s potential into widespread practical application. \nThis workshop, “Open Challenges in Simulation-Based Inference,” will bring together domain scientists actively employing SBI and developers of core SBI methodologies to identify and address these critical bottlenecks. \nWe aim to foster a collaborative environment for knowledge exchange, promoting mutual understanding of needs, benefits, and limitations across diverse scientific fields. While SBI methods have advanced rapidly, their application often faces hurdles related to computational cost, robustness to noise, scalability to high-dimensional parameter spaces, and effective integration into existing scientific workflows. Many domain scientists encounter specific challenges unique to their fields that are not adequately addressed by current methodological developments. \nThis workshop directly addresses the need for a dedicated space to bridge this gap, facilitating a dialogue between end-users and method developers. Addressing these challenges is crucial for unlocking the full potential of SBI and accelerating scientific progress across disciplines. \nRegistered participants (on ConfTool) can also submit an abstract for our poster session (deadline April 29th EOD):\nhttps://events.hifis.net/event/3955/abstracts/\nThis workshop aligns with the HAICON’s focus on scientific interdisciplinary research using machine learning.\nThis workshop will employ a highly interactive format designed to maximize engagement and knowledge sharing:\n\n\n[60 min] Keynote Address: A leading expert will present a comprehensive overview of the current state of SBI methods, outlining recent advancements and highlighting open research questions. (We are actively pursuing [Keynote Speaker Name/Area of Expertise] as a potential speaker.)\n\n\n[30 min] Lightning Talks: Selected poster presenters will deliver concise (3-5 minute) lightning talks to introduce their challenges and research to the broader audience.\n\n\n[120 min] Poster Session & Challenge Forum: The core of the workshop, dedicated to in-depth discussion and exploration of submitted posters. We will utilize structured community interviews during the poster session to systematically identify common challenges and potential solutions.\n\n\n[30 min] Wrap-up & Summary: A facilitated discussion will synthesize key findings from the poster session and lightning talks, leading to a concise summary of identified challenges and potential research directions.\n\n\n-\nGoals:\nSimulation-based inference (SBI) has become an essential tool across a wide and rapidly growing range of scientific domains — from biology and astronomy to geology and physics. Yet despite this breadth, practitioners across these fields frequently encounter the same fundamental challenges: questions about scalability, model misspecification, validation, and the gap between methodological advances and practical applicability. These challenges are rarely addressed in a cross-domain setting, leaving communities to rediscover solutions in isolation. This workshop aims to change that. By bringing together SBI method developers, domain scientists, and practitioners under one roof, we seek to create a dedicated space for structured exchange that is rarely possible within the boundaries of a single-domain conference. Our concrete objectives are to foster the adoption and continued development of SBI by connecting those who build these methods with those who apply them; to sharpen the community\'s collective understanding of the limitations of SBI and the mitigations available; and to provide an accessible, representative overview of the field that serves both newcomers and experienced practitioners.\n-\nPresenters Experience:\nThe workshop is organized by:\n\n\nDr Alina Bazarova, Helmholtz AI consultant at Forschungszentrum Jülich and a subgroup leader\n\n\nPeter Steinbach, head of AI consultants in Helmholtz Zentrum Dresden Rossendorf\n\n\n\nGiuseppe Viterbo, IMPRS PhD Candidate, University of Heidelberg\n\nWe hope to attract a seasoned sbi scientist to deliver an in-depth keynote to kick-off our workshop.\n- \nTarget Audience:\nSBI users from any scientific domain and SBI method developers\n- \nKeywords:\nInverse Problems, Generative AI, Simulation-Based Inference, Community, Machine Learning

Location: CON 1+2
Session Chair: Anis Ismail, KU Leuven
Session Chair: Saptarshi Chakrabarti, KU Leuven
Brief Description and Outline:\nThis workshop will focus on standardized benchmarking and reproducible evaluation of multiomics integration methods in bioinformatics, using Multiverse as a unifying framework rather than as the sole focus. The session will begin with a 15-minute conceptual overview of multimodal integration challenges, model diversity, and current limitations in benchmarking practices.\nWe will then dedicate 15-minutes to a structured review of representative integration approaches, emphasizing their assumptions, strengths, and limitations in biological contexts.\nThe core of the workshop will consist of two hands-on blocks. The first 30-minute session will guide participants through running a standardized benchmarking workflow: selecting curated datasets, configuring preprocessing pipelines, training multiple integration models, performing hyperparameter optimization, and evaluating results using multiple integration metrics. The second 60-minute session will focus on extensibility and community benchmarking: integrating a custom model within a containerized setup and performing comparative analysis across methods.\nWe will explicitly demonstrate how containerization resolves dependency conflicts and ensures\nreproducibility across heterogeneous tools. Overall, the tutorial balances theoretical context, coverage of representative methodological families, and practical reproducible workflows, ensuring relevance beyond a single framework while providing concrete skills for multi-omics integration\nresearch.\n\nGoals:\nThe primary goal of this tutorial is to equip participants with a rigorous and practical understanding of how to benchmark multi-omics integration methods in a standardized and reproducible manner. Participants will learn how to design fair comparisons across heterogeneous models, select appropriate evaluation metrics aligned with biological objectives, and interpret performance trade-offs between modality alignment, clustering quality, and biological signal preservation.\nA second goal is to provide hands-on experience with reproducible computational workflows. Participants will gain practical skills in running containerized pipelines, managing model dependencies, performing systematic hyperparameter optimization, and executing end-to-end benchmarking experiments across multiple datasets and methods.\nA third goal is to foster extensibility and community-driven benchmarking. Attendees will learn how to integrate new datasets, add custom models, and implement additional evaluation metrics within a unified framework, enabling them to adapt benchmarking workflows to their own research questions. By the end of the tutorial, participants will be able to critically assess integration methods and build reproducible, extensible benchmarking pipelines for multi-omics data analysis.\n\nPresenters Experience:\nAnis Ismail is a second-year PhD researcher at the Laboratory of Multi-Omic Integrative Bioinformatics working on explainable multi-omic representation learning models. He is currently President of the ISCB Regional Student Group Belgium and has co-organized the Interuniversity Belgian Biohackathon (September 2025). He also leads the Data for Good Challenge at Emergent, designing and organizing Leuven’s biggest Data Science Challenge. He also has substantial teaching and outreach experience, including workshops on AI and data science at Beirut AI, Zaka, SE Factory, and Lebanese American University. He will be leading the workshop, and will focus on multi-omics representation learning concepts, benchmarking methodology and demonstrating containerized workflows.\nSaptarshi Chakrabarti is a data engineer at the Leuven Institute of Single Cell Omics where he develops scalable machine learning infrastructure for computational biology. He contributed to the MLOps and workflow automation components of the Multiverse framework, with expertise in reproducible research software engineering, pipeline deployment, and maintainable ML systems in academic environments. He has mentored undergraduate programming courses at KU Leuven and presented a technical demo at RSE Day 2025 at KU Leuven. His role in the workshop will be focusing on the practical implementation aspects of benchmarking multi-omics models and technical support of attendees.\n\nTarget Audience:\nThe target audience includes master’s students, PhD students, and researchers working in single-cell and multi-modal bioinformatics. Participants are expected to have a basic understanding of machine learning concepts and familiarity with biological data analysis. Practical experience with Python and computational workflows is recommended, as the tutorial will involve hands-on benchmarking, model training, and evaluation of multi-omics integration methods. Prior knowledge of deep learning is helpful but not strictly required, as core methodological ideas will be introduced during the session.\n\nKeywords:\nMulti-omics integration, Benchmarking, Deep learning, Containerization, Reproducibility, Model evaluation, Bioinformatics tools

Brief Description and Outline:\nJoint introduction (~12 min)\nElla Bahry and Deborah Schmidt will give a short overview of PixelPatrol, and Hans Werners and Philipp Heuser will introduce the Helmholtz Model Zoo. The two tools address opposite ends of the AI pipeline in scientific imaging: PixelPatrol helps you understand and curate your data before training, while the Helmholtz Model Zoo lets you share and run inference with the resulting trained models.\nTrack A: PixelPatrol\nPixelPatrol is an open-source quality control and data exploration tool for scientific image datasets. It systematically profiles imaging data and generates interactive dashboard reports with statistics and visualizations, making it a useful first step before any computationally intensive analysis or AI model training.\nParticipants will work with their own datasets or a provided example (aqQua foundation model training data). The session covers generating comprehensive quality reports; interpreting visualizations including file stats, metadata consistency, and image statistics; interactive filtering and grouping; identifying outliers, artifacts, and acquisition inconsistencies; and an introduction to developing custom PixelPatrol packages and plugins.\nTrack B: Helmholtz Model Zoo\nThe Helmholtz Model Zoo (HMZ) is a cloud-based platform for sharing and running inference on deep learning models across the Helmholtz Association. It is integrated with Helmholtz infrastructure, including Helmholtz ID, dCache, and DESY\'s HPC cluster with NVIDIA L40S GPUs. Users can run inference via both a web interface and a REST API, with support for datasets from gigabytes to terabytes. NVIDIA Triton Inference Server and Slurm manage GPU resources, and virtual organizations enable fine-grained access control across scientific domains.\nParticipants will go through the steps required to prepare and deploy a model on the HMZ, including an overview of available deployment templates. Participants are encouraged to bring their own model or an open-source model they would like to deploy (for example, from Hugging Face); an example model will also be provided. Those who want to prepare in advance are welcome to reach out at support@helmholtz-imaging.de.\n\nGoals:\nPixel Patrol: This hands-on workshop introduces participants to systematic data curation practices for scientific image datasets using PixelPatrol, an open-source tool for dataset exploration and quality control.\nParticipants will learn to identify data quality issues before computationally expensive analysis, explore dataset characteristics interactively, and implement quality control workflows that prevent common pitfalls in imaging pipelines and AI model training.\nWith PixelPatrol it will be possible to generate fingerprints of the training data, which can be used in the context of the HMZ to support users to identify trained models where the fingerprint of the training data suggests successful inference to the users data\nWe will also provide an outlook on how both Pixel Patrol and the Model Zool will be integrated in the near future.\n\nPresenters Experience:\nElla Bahry and Deborah Schmidt (Helmholtz Imaging, MDC Berlin) co-lead PixelPatrol development and both teach at HIDA.\nHans Werners (Helmholtz Imaging, DESY Hamburg) is the primary developer of the Helmholtz Model Zoo.\nPhilipp Heuser leads the Helmholtz Imaging Support and Engineering team at DESY and is deeply involved in HMZ development.\n \nTarget Audience:\nImaging researchers working with large or heterogeneous datasets, scientists preparing data for AI/deep learning workflows, data curators, research software engineers, and ML practitioners wanting to make their models accessible to the Helmholtz community. Participants should bring a laptop and, optionally, a dataset or model they would like to work with.\n \nKeywords:\ndata curation, image quality control, dataset exploration, deep learning workflows, data integrity, metadata validation, FAIR research, model deployment, Helmholtz Model Zoo, inference

Session Chair: Julian Beimes, idalab GmbH
Brief Description and Outline:\nDesigning GDPR-compliant projects is challenging for many researchers, resulting in long approval cycles, repeated changes to the project design and suboptimal technical setups. This hands-on workshop introduces a six-step process for translating research concepts into lean, GDPR-compliant project designs. Participants will then practice by applying the process on three cases involving healthcare data. The workshop is suitable for all participants working with personal data in the EU. No GDPR expertise is required, basic data protection concepts (e.g. pseudonymization vs anonymization) should be familiar.\nAgenda:\n(1) Introduction, Objectives, Agenda, Expectations (10 min): We introduce the structure of the session and gather input from participants on common GDPR-related challenges in their projects.\n(2) GDPR-compliant design in six steps (20 min): Participants are introduced to a six-step process which takes them from a research concept to a GDPR-compliant project design. The six steps cover GDPR scope assessment, data classification, processing options, roles and responsibilities, international data transfers, and safeguards. In preparation for the group exercises, the three cases and supporting material for the case practice are presented. The cases are based on real-world projects and involve common challenges encountered in research projects, e.g. combining personal data from several countries.\n(3) Group Case Exercises (40 min): In small groups of two to six, participants apply the six-step process to one of the three cases. They analyze requirements, explore data processing options, and develop GDPR-compliant project designs.\n(4) Group Presentations & Discussion (40 min): Each group presents its solution, key decisions, and underlying reasoning. Common patterns, trade-offs of different approaches and open questions are discussed.\n(5) Wrap-Up & Takeaways (10 min): The workshop concludes with a summary of key insights, pitfalls, and practical guidance. Participants will get a one-pager hand-out, which describes the six steps and provides practical examples how to apply them.\n\nGoals:\nBy the end of the workshop, participants will be able to:\n(1) Apply a six-step process to design GDPR-compliant research projects,\n(2) Evaluate GDPR-related options early in the project,\n(3) Discuss GDPR-related issues confidently with data protection officers or IT specialists. Designing projects in a GDPR-compliant way from the outset helps avoid delays, unnecessary iterations, and compliance risks, thereby speeding up research projects.\n\nPresenters Experience:\nJulian Beimes is Associate Principal at idalab GmbH, where he supports medtech and biopharma companies in conceptualizing and implementing AI solutions.\n\nTarget Audience:\nThe workshop is aimed at scientists and research professionals who design, lead, or contribute to data-driven projects involving personal data. No GDPR expertise is required, basic data protection concepts (e.g. pseudonymization vs anonymization) should be familiar.\n\nKeywords:\nGDPR, Project Design, Data Processing

Location: CON 3
Session Chair: Christopher Koska, University Augsburg
Session Chair: Markus Schatzl, senswork GmbH
Brief Description and Outline:\nThis workshop addresses how ethical, fairness-related, and sustainability considerations can be systematically embedded into industrial AI projects. While industrial AI systems increasingly rely on predictive models and uncertainty-aware decision support, ethical aspects are often addressed late, implicitly, or inconsistently. The workshop focuses on practical, method-oriented approaches that help integrate responsibility into AI projects without slowing down innovation. \nRather than presenting specific software or algorithms, the session emphasizes transferable concepts such as uncertainty-aware decision-making, data governance, and Corporate Digital Responsibility (CDR). Participants will work with representative industrial AI scenarios involving tabular and time-series data, such as predictive models in production contexts. The workshop treats Responsible AI as a set of practices and methods that shape how predictive models are designed, deployed, and embedded in organizational contexts.\nOutline (2 hours):\n\n\nIntroduction & framing (20 min) - Responsible AI challenges in industrial decision-making\n\n\nImpulse: Ethics, uncertainty, and governance (20 min) - Key concepts and methodological perspectives\n\n\nGroup work: Case-based analysis (40 min) - Identification of ethical risks, uncertainties, and responsibility gaps\n\n\nPlenary discussion (20 min) - Comparing approaches and trade-offs\n\n\nSynthesis & takeaways (20 min) - Translating ethical reflection into project practice\n\n\n-\nGoals:\nThe goal of this workshop is to provide participants with practical orientation on how to integrate ethics, fairness, and sustainability into industrial AI projects. The session aims to demonstrate that ethical reflection can function as a structuring element for clarity, robustness, and trust in data-driven decision-making. The workshop contributes to HAICON26 by bridging conceptual frameworks with real-world AI practice and fostering dialogue between researchers and industry practitioners. Responsible AI is conceptualized not as a checklist, but as a structured approach to shaping practices and methods in industrial AI projects.\n-\nPresenters Experience:\nDr. Christopher Koska, Senior Researcher and coordinator of the work package “Ethics” within the transfer project VoMoPro at the Centre for Future Production, University of Augsburg.\nHis work focuses on Responsible AI as an application-oriented framework for shaping ethical and organizational practices in socio-technical contexts and supporting knowledge transfer between research and practice. He holds a PhD in philosophy with a monograph on the ethics of algorithms and has over 15 years of experience in designing and facilitating workshops and training formats on Corporate Digital Responsibility, with a focus on data and algorithmic ethics, in both academic and industry settings.\nMarkus Schatzl, Director of the Innovation Lab at senswork, responsible for innovation processes and the professional development of employees. \nHis work focuses on translating AI-based technologies into organizational practice, with particular attention to innovation processes, responsibility, and human-centered design. In addition to internal training formats, he regularly designs and conducts workshops and educational programs for external audiences, including students and pupils, addressing digital technologies, innovation, and responsible technology use.\nTarget Audience:\nThe workshop targets researchers and practitioners working on industrial AI systems, including machine learning researchers, data scientists, engineers, and project managers. A basic understanding of AI concepts and data-driven decision-making is expected; no prior expertise in AI ethics is required.\n \nKeywords:\nResponsible AI; Ethically Aligned Design; Embedded Ethics; Corporate Digital Responsibility; Industrial AI; Uncertainty Quantification; Data Governance; Decision Support.

Brief Description and Outline:\nThis workshop aims to actively discuss the role of concepts of causality in complex dynamic systems and how the application of these concepts can be challenging to address in medicine and biology.\nUnderstanding cause–and–effect relationships rather than pure correlations is the aim of causal modeling, including causal inference and causal AI. Causal inference and reinforcement learning developed as separate disciplines with distinct terminologies yet address mathematically related problems. Recent work has begun to reveal these fundamental connections: online reinforcement learning inherently captures causal relationships, whereas traditional methods show that advantage functions and mean-cantered blip functions are mathematically equivalent objects under uniform policies, and the inverse probability of treatment weighting represents the same probability weighting principle as importance sampling in contextual bandits.\n\nHowever, causal inference in complex systems must account for limited completeness and contextual causality, particularly in biological and physiological domains where feedback loops and multiscaling create temporal dependencies that static causal diagrams cannot capture. On the other hand, statistical methods, such as synergistic, unique and redundant components (SURD), attempt to solve inherent  problems of causality in complex dynamical systems by determining the specific nature of causal relationships, such as whether two variables are synergistic, i.e., whether one variable only influences another if it is paired with a second variable.\n\nThis workshop explores how recent advances in causal discovery using reinforcement learning, estimation of heterogeneous treatment effects, and adaptive experimental design provide opportunities for practitioners to use methods from both modeling methods, namely, reinforcement learning and causal AI. Additionally, we will thematize how to address, for example, complex biological systems that exhibit persistent dependencies and emergent properties that violate standard assumptions in both causal inference and reinforcement learning.\n-\nBuilding on these observations, the workshop addresses three fundamental questions at the interface of causal inference and reinforcement learning in biomedical systems:\n• First, when do control objectives permit bias that inference objectives cannot tolerate, for instance, when optimizing treatment sequences from observational data?\n• Second, how do we handle systems where traditional Markovian assumptions fail?\n• Third, what new methodological opportunities emerge from the explicit recognition of these translational synergies?\n-\nThis discussion emphasizes practical implications for researchers working across causal inference and machine learning divides, particularly in domains requiring sequential decision-making under uncertainty with observational data constraints.

Brief Description and Outline:\nThis workshop aims to actively discuss the role of concepts of causality in complex dynamic systems and how the application of these concepts can be challenging to address in medicine and biology.\nUnderstanding cause–and–effect relationships rather than pure correlations is the aim of causal modeling, including causal inference and causal AI. Causal inference and reinforcement learning developed as separate disciplines with distinct terminologies yet address mathematically related problems. Recent work has begun to reveal these fundamental connections: online reinforcement learning inherently captures causal relationships, whereas traditional methods show that advantage functions and mean-cantered blip functions are mathematically equivalent objects under uniform policies, and the inverse probability of treatment weighting represents the same probability weighting principle as importance sampling in contextual bandits.\n\nHowever, causal inference in complex systems must account for limited completeness and contextual causality, particularly in biological and physiological domains where feedback loops and multiscaling create temporal dependencies that static causal diagrams cannot capture. On the other hand, statistical methods, such as synergistic, unique and redundant components (SURD), attempt to solve inherent  problems of causality in complex dynamical systems by determining the specific nature of causal relationships, such as whether two variables are synergistic, i.e., whether one variable only influences another if it is paired with a second variable.\n\nThis workshop explores how recent advances in causal discovery using reinforcement learning, estimation of heterogeneous treatment effects, and adaptive experimental design provide opportunities for practitioners to use methods from both modeling methods, namely, reinforcement learning and causal AI. Additionally, we will thematize how to address, for example, complex biological systems that exhibit persistent dependencies and emergent properties that violate standard assumptions in both causal inference and reinforcement learning.\n\nBuilding on these observations, the workshop addresses three fundamental questions at the interface of causal inference and reinforcement learning in biomedical systems:\n• First, when do control objectives permit bias that inference objectives cannot tolerate, for instance, when optimizing treatment sequences from observational data?\n• Second, how do we handle systems where traditional Markovian assumptions fail?\n• Third, what new methodological opportunities emerge from the explicit recognition of these translational synergies?\n\nThis discussion emphasizes practical implications for researchers working across causal inference and machine learning divides, particularly in domains requiring sequential decision-making under uncertainty with observational data constraints. Applications span clinical decision support systems where treatment sequences must be optimized from observational data, adaptive trial designs that balance exploration and exploitation while maintaining statistical validity, digital twins (DTs) where therapies or the toxic effects of substances are tested on in silico models of real organisms, and policy evaluation in public health where experimental manipulation is impossible.\n\nOutline of the Workshop\n• 20 min Introduction session including presenters and participants\n• 1-hour in-depth presentations of presenters\n• 20 min Introduction group work = Setting scene/clinical vignette/t thematic context: particularly in domains requiring sequential decision-making under uncertainty with observational data constraints.\n• 50 Minutes an active parallel workshop on one of the three fundamental open questions from the perspective of causality and reinforcement learning:\n1.

WS 9b - Curiosity, Exploration, and Meta-Reinforcement Learning: Learning What to Learn
11:15am - 1:15pm
HPC 002
Jonathan Shock
Location: HPC 002
Session Chair: Jonathan Shock, University of Cape Town
Brief Description and Outline:\nAgentic AI is becoming ubiquitous, but how an agent learns to navigate an environment efficiently remains an open problem. This session traces the exploration problem from its classical formulation in reinforcement learning (where the tension between exploiting known rewards and discovering better ones is unavoidable) through to contemporary approaches rooted in intrinsic motivation, meta-learning, and the free energy principle. The arc moves from hand-designed exploration heuristics toward increasingly principled accounts of curiosity, culminating in active inference as a unifying framework that grounds exploration in Bayesian brain theory and statistical mechanics. Relevance: Efficient exploration is a bottleneck in deploying RL to many real-world problems where rewards are sparse, environments are complex, and data is expensive, making it central to both theoretical and applied AI research. Beyond engineering, the topic sits at the intersection of machine learning, dynamical systems, and computational neuroscience, offering a lens through which mathematical structure can illuminate biological as well as artificial intelligence. Researchers across these fields may find direct connections to open problems in their own work, whether in algorithm design, cognitive modelling, or the foundations of learning theory.\n\nOutline:\n1) Reinforcement Learning and the Exploration Problem (20 min)\n2) Curiosity and Intrinsic Motivation in RL (30-40 min)\n3) Meta-Reinforcement Learning and Learning-to-Explore (20 min)\n4) Active Inference Frameworks (20 min)\n5) Discussion and Open Questions (20-30 min)\n\nGoals:\nTo provide a conceptual map of modern exploration and curiosity-driven methods in reinforcement learning. To clarify the relationship between intrinsic motivation, meta-learning, and adaptive behaviour and to highlight connections between reinforcement learning, Bayesian inference, and active inference frameworks. Also, to equip participants with principled ways to reason about exploration strategies beyond ε-greedy or ad-hoc heuristics.\n\nPresenters Experience:\nJonathan Shock is an Associate Professor in the Department of Maths and Applied Maths at the University of Cape Town, where he directs the UCT AI Initiative. He is also an Adjunct Professor at INRS Montréal. His work spans theoretical physics, reinforcement learning, and computational neuroscience, with a focus on understanding intelligence as a dynamical and physical process. He is particularly interested in reinforcement learning, multi-agent systems, and theory-driven AI for science. Much of his research explores how mathematical structure — from statistical mechanics to dynamical systems — can inform the design and analysis of learning systems. He completed his PhD at the University of Southampton in 2005 on applications of string theory to quantum chromodynamics, followed by postdoctoral appointments in Beijing, Santiago de Compostela, and Munich before joining UCT in 2013.\n\nTarget Audience:\na) PhD students, postdoctoral researchers, and early-to mid-career researchers\nb) Participants with a basic familiarity with machine learning or reinforcement learning\nc) Researchers from computer science, applied mathematics, neuroscience or robotics.\nThis tutorial is designed as a 2-hour session focusing at a semi-technical level introducing a range of topics but not expecting mastery. No coding or specialised software is required, but some mathematics background is expected.
TT 9c - Uncertainty Quantification for Neural Networks: Make your model predictions trustworthy

Session Chair: Christoph Schweden, German Aerospace Center
Brief Description and Outline:\nIn machine learning, the ability to make reliable predictions is paramount. Yet, standard ML models and pipelines provide only point predictions without accounting for model confidence (or the lack thereof). Uncertainty in model outputs, especially when faced with out-of-distribution (OOD) data, is essential when deploying models in production. This tutorial serves as an introduction to the concepts and techniques for quantifying uncertainty in machine learning models. We will explore the different sources of uncertainty and cover various methods for estimating these uncertainties effectively.\n\nGoals:\nProvide participants with basic knowledge and go-to tools and methods for applying UQ in their Work.\n\nPresenters Experience:\nSteve Schmerler, AI consultant @HZDR, has hosted an UQ workshop and world cafe table at previous HAICONs. Further, he has been teaching neural net intro courses such as https://github.com/elcorto/2024-thrill-school-machine-learning and has developed educational material for Gaussian processes (https://elcorto.github.io/gp_playground).\nJakob Gawlikowski is a PhD Student at German Aerospace Center (DLR) and Technical University of Munich.\nChristoph Schweden is a postdoctoral fellow at German Aerospace Center (DLR).\n\nTarget Audience:\nFamiliarity with neural nets, basic probability (ML textbook level), Bayesian stats would be ideal but not required.\n\nKeywords:\nUncertainty, approximate Bayesian, calibration
