Welcome back to our Materials Informatics series! In today's episode, we delve into Bayesian Optimization, a critical tool for incrementally improving processes and designs in materials research. Bayesian Optimization leverages Bayes' theorem to make informed decisions with minimal data, making it particularly valuable in material science, where property trade-offs are common.
Here's a brief overview of what we'll cover:
Introduction to Bayesian Optimization: Understanding the basics and why it's essential for material science.
Real-World Application: An example of optimizing 3D printing parameters using Bayesian Optimization.
Surrogate Models and Acquisition Functions: How these components help in efficiently exploring the design space.
Multi-Objective Optimization: Balancing trade-offs like strength vs. cost or performance vs. durability.
Tools and Implementation: An introduction to popular tools like Ax, BoTorch, Dragonfly, and more.
For those interested in a deeper dive, check out our dedicated playlist on Bayesian Optimization: Bayesian Optimization Playlist. This series covers everything from basic concepts to advanced techniques, including handling multi-objective scenarios and incorporating multi-fidelity data.
