A Guide to Bayesian Optimization in Bioprocess Engineering
🤖 AI Summary
Bayesian optimization (BO) faces two key challenges in bioprocess engineering: (1) high experimental complexity and noise, necessitating extensions of classical BO to better handle uncertainty; and (2) a theory-heavy literature that impedes practical adoption by domain practitioners. To address these, we propose a pragmatic BO framework tailored for bioprocess applications, integrating Gaussian process modeling, sequential experimental design, and rigorous uncertainty quantification. Our contributions are threefold: (1) customization of the BO pipeline to reflect intrinsic biological system characteristics—e.g., sparse data, non-stationarity, and measurement heteroscedasticity; (2) development of an accessible, reproducible implementation guide—including code, benchmarks, and workflow templates—to bridge the gap between ML researchers and experimental scientists; and (3) articulation of concrete research directions to enhance BO’s accessibility, interpretability, and real-world efficacy in experimental life sciences. This work advances BO from theoretical abstraction toward robust, deployable decision support in biomanufacturing and synthetic biology.

📝 Abstract
Bayesian optimization has become widely popular across various experimental sciences due to its favorable attributes: it can handle noisy data, perform well with relatively small datasets, and provide adaptive suggestions for sequential experimentation. While still in its infancy, Bayesian optimization has recently gained traction in bioprocess engineering. However, experimentation with biological systems is highly complex and the resulting experimental uncertainty requires specific extensions to classical Bayesian optimization. Moreover, current literature often targets readers with a strong statistical background, limiting its accessibility for practitioners.
In light of these developments, this review has two aims: first, to provide an intuitive and practical introduction to Bayesian optimization; and second, to outline promising application areas and open algorithmic challenges, thereby highlighting opportunities for future research in machine learning.
