This tutorial 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 realized via jupyter notebooks.
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 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.
- Learn how to design and implement SBI frameworks for representative 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.
Learning Outcome:
The ability to set up a Bayesian approach within a given framework
