As per its tradition, ICHI 2025 will host invited talks from outstanding speakers.
Keynote #1, June 18th – The AI-Driven Hospital of the Future
Speaker: Pierre Baldi, UnivERSITY OF CALIFORNIA AT Irvine, Ca, USA
Speaker’s short bio: Pierre Baldi grew up in Rome and earned MS degrees in Mathematics and Psychology from the University of Paris, and a PhD in Mathematics from the California Institute of Technology. He is currently Distinguished Professor in the Department of Computer Science, Director of the AI in Science Institute, and Associate Director of the Center for Machine Learning and Intelligent Systems at the University of California Irvine.
The long term focus of his research is on understanding intelligence in brains and machines. He has made several contributions to the theory of AI and deep learning, and developed and applied AI and deep learning methods for the natural sciences, to address problems in physics (e.g., exotic particle detection) , chemistry (e.g., reaction prediction), and bio-medicine (e.g., protein structure prediction, biomedical imaging analysis), circadian rhythms. He recently published his fifth book: Deep Learning in Science, Cambridge University Press (2021). His honors include the 1993 Lew Allen Award at JPL, the 2010 E. R. Caianiello Prize for research in machine learning, the 2023 Dennis Gabor Award, and election to Fellow of the AAAS, AAAI, IEEE, ACM, and ISCB. He has co-founded several startup companies.
Abstract: Artificial Intelligence (AI) today can pass the Turing test and is in the process of transforming science, technology, society, humans, and beyond. Surprisingly modern AI is built out of two very simple and old ideas, rebranded as deep learning: neural networks and gradient descent learning. I will describe several applications of AI to problems in biomedicine developed in my laboratory, from the molecular level to the patient level using omic data, imaging data, clinical data,text data, and beyond. I will discuss the opportunities and challenges for developing, integrating, and deploying AI in the first AI-driven hospitals of the future and present two frameworks for addressing some of the most pressing societal issues related to AI research and AI safety.

Prof. Peleg is internationally renowned in the area of clinical decision support, with a focus on clinical-guideline based decision support and using ontologies to integrate patient data with clinical knowledge. She received AMIA’s New Investigator Award in 2005 for her work on the GLIF3 computer-interpretable guideline language.
She led the large-scale European project MobiGuide, providing sensor-monitoring and evidence-based personalized decision-support to patients any time everywhere. Her current research exploits AI and Big Data for a new model of cancer care (https://capable-project.eu/).
Abstract: My research focuses on developing methods that integrate domain knowledge with machine learning to support clinical decision-making. The source of clinical knowledge is evidence based clinical guidelines, and machine learning methods are used to provide personalize the clinical recommendations and their delivery. In my talk, I will focus on two applications.
1. Personalizing Digital Health Behaviour Change Interventions using Machine Learning and Domain Knowledge (with Aneta Lisowska and Szymon Wilk). We are developing a virtual coaching system that helps patients adhere to behavior change interventions (BCI) based on behavioral theory. Our proposed system predicts whether a patient will perform the targeted behavior (recommended by the clinical guideline) and uses counterfactual examples with feature control to guide personalization of BCI. We use simulated patient data with varying levels of receptivity to intervention to arrive at the study design that enables preliminary evaluation of our system.
2. Generating Ontology-Learning Training-Data through Verbalization (with Antonio Zaitoun and Tomer Sagi). Ontologies are very useful tools for health data integration and semantic reasoning. Yet, their maintenance and update is usually manually done. Our overall vision is to use LLMs to support ontology learning based on evidence-based clinical knowledge. Unlike previous work on LLM-based knowledge graph extension, ontologies present unique challenges, and in particular Web Ontology Language (OWL) axiom generation, as such controlled language is different than natural languages. To fine-tune LLMs so they could output OWL axioms, we needed to create a data set of pairs of ontology axioms and their natural language translations. We therefore developed an LLM-assisted verbalizer, specifically for the task of converting OWL statements from existing ontologies into natural text. We evaluated our approach on 322 classes from four different ontologies using two different LLMs, achieving precision and recall as high as 0.99 and 0.96, respectively.

Abstract: The 21st century has witnessed major challenges caused by both COVID19 pandemic and aging society. In this talk, I will discuss the grand challenges and opportunities in AI for healthcare, and show some examples in areas such as AI Foundation Models, AI Implementation Science, and Metaverse. In AI Foundation Models, OpenAI LLMs primarily pretrain web-searched data. They are susceptible to hallucinated information and lack logical reasoning. Thus the healthcare LLMs require more domain expertise, patient specific data, logical reasoning to handle complex inferences, and computation and transparency for broad adoption in clinical settings. Working with Microsoft Accelerating Foundation Models Research, we developed the first retrieval augmented generation (RAG) solutions for clinical setting that augments LLMs with the most recent domain-specific medical knowledge. We then developed EHRAgent that augments external tools and medical knowledge to solve few-shot multi-tabular reasoning derived from EHRs (Electronic Health Records). EHRAgent formulates a clinical problem-solving process as an executable action sequence code plan with a code executor. Using interactive coding between the LLM agent and cod executor, the environment is feedback to improve code generation for tabular reasoning tasks in EHR. Compared to the state-of-the-art agent AutoGen, EHRAgent has 36% improvement, and has been published in Annual Meeting of the Association for Computational Linguistics (ACL2024) and the Empirical Methods in Natural Language Processing (EMNLP2024). Besides foundation model, our effort in AI Implementation Science has been accepted into AMIA 3-Tier AI Showcase, and our effort in real-time Digital Twin and Metaverse for rehabilitation have been accepted into Intelligent Reality conferences.

Abstract: Biological networks of an organism show how different bio-chemical entities, such as enzymes or genes interact with each other to perform vital functions for that organism. Dr. Kahveci’s lab is focusing on developing computational methods that will help in understanding the functions of large-scale biological networks. In this talk, we will focus on how different network models, such as static, probabilistic, dynamic, and multilayer models, address various challenges in computational biology. We will first consider challenges centered on uncertainty in the topology of biological networks. We will discuss our new mathematical model, which represent probabilistic networks as collections of polynomials. We show that this is a powerful model that enables solving seemingly very tough computational problems on probabilistic networks efficiently and precisely. We will then discuss how the dynamic behavior of the network affects how we can approach to some of the fundamental computational problems on biological network analysis such as motif counting and finally talk about how these solutions can enhance our understanding of next generation spatial transcriptomics and spatiotemporal transcriptomics data.
