Description
This tutorial introduces Simulation-Based Inference (SBI), a framework combining Bayesian modeling, AI techniques, and high-performance computing (HPC) to address key challenges in computational biology, such as performing reliable inference with limited data by using AI-based approximate Bayesian computation. Moreover, it tackles the problem of intractable likelihood functions, thereby allowing to utilize Bayesian inference for biological systems with multiple sources of stochasticity. The tutorial also demonstrates how to leverage HPC environments to drastically reduce inference runtimes, making it highly relevant for large-scale biological problems. This tutorial bridges theoretical foundations with hands-on applications in computational biology. Participants will learn to implement SBI frameworks using diverse biological models, such as molecular dynamics simulations, agent-based tumor growth models, count data modeling, and Lotka-Volterra systems. Practical exercises in Jupyter notebooks guide attendees through SBI workflows, from simple coin-flipping examples to more complex biological simulations, ensuring accessibility for participants with varied backgrounds. The tutorial’s inclusion of cutting-edge methods like Sequential Neural Posterior Estimation and its emphasis on parallelization and HPC scalability align closely with the scientific community's focus on innovation in computational biology. A previous iteration of the tutorial at the Helmholtz AI Conference 2024 received excellent reviews and led to interdisciplinary discussions, highlighting its broad applicability and impact. For this conference, the content has been further refined with additional examples relevant to the community, ensuring it meets the needs of bioinformatics researchers.

Learning Objectives

• Understand the Principles of Simulation-Based Inference (SBI): learn the theoretical foundations of SBI, including its relationship with Bayesian inference and its advantages in handling complex biological systems.
• Explore SBI Methods (SNPE, SNLE, and SNRE): gain an understanding of Sequential Neural Posterior Estimation (SNPE), Sequential Neural Likelihood Estimation (SNLE), and Sequential Neural Ratio Estimation (SNRE) and their applications in computational biology.
• Learn how to design and implement SBI frameworks for representative biological scenarios, such as molecular dynamics, cell growth, count data modeling, and Lotka-Volterra systems.
• Leverage HPC for SBI Workflows: understand how to use high-performance computing (HPC) environments to scale SBI workflows and efficiently distribute computational workloads.

Intended Audience and Level
This tutorial is designed for researchers working in computational biology and bioinformatics, modeling natural processes, and applying AI or Bayesian inference techniques. It is well-suited for:

• Researchers seeking to infer model parameters from sparse or simulated data.

Description
Agentic workflow is a process of interacting with Large Language Models (LLMs) to complete complex tasks - allowing practitioners to build pipelines that integrate data retrieval, reasoning, and execution steps. This tutorial will guide participants through the conceptual and practical foundations of setting up their own agentic workflows. By combining prompt engineering techniques, retrieval-augmented generation tool use and deployment strategies that safeguard data privacy, tutorial participants will learn how to build, deploy and tune their own personal copilots for use in bioinformatics workflows.

The capabilities of agentic workflows—driven by improving LLMs —are rapidly expanding, while cloud offerings are making these advanced computational tools more accessible than ever before. By integrating agentic workflows into bioinformatics pipelines, practitioners can significantly reduce their time-to-analysis. Lowering the barrier to entry for novices and allowing expert practitioners to scale their work with greater efficiency, these workflows democratize cutting-edge computational methods and ensure that the tutorial participants can capitalize and leverage the latest advances in their work and careers in general. This tutorial will integrate state-of-the-art prompting techniques, retrieval augmentation strategies, add context to model selection and explore the fundamentals between choosing amongst the different techniques and current trends.

Learning Objectives

• Develop a theoretical and practical understanding and experience of how to integrate and automate bioinformatics analyses using LLM agents
• Gain hands-on experience building agentic workflows for bioinformatics
• Learn current trends in agentic workflows, fundamentals and differences of LLM models, best practices in writing prompts and deploying local LLM agents
• Understand how to extend and customize existing tools to fit specific research domains or specialized datasets

Intended Audience and Level
The tutorial is aimed at bioinformaticians who are beginners in AI and LLMs. However, it is strongly recommended to have programming experience in Python as well as using command line tools and bioinformatics software.

Attendees should have:

• Working knowledge of Python, package management and the command line (Unix)
• Familiarity with standard bioinformatics data formats and tools (e.g., FASTA, FASTQ)
• PC with a Python environment set up prior to the tutorial (exact requirements to be defined later)
• Comfortable understanding of basic bioinformatics concepts and common analysis pipelines

Participants will be provided with installation instructions in advance to ensure a smoother experience.
