Machine Learning Optimization of Lignin Properties in Green Biorefineries

نویسندگان

چکیده

Novel biorefineries could transform lignin, an abundant biopolymer, from side-stream waste to high-value-added byproducts at their site of production and with minimal experiments. Here, we report the optimization AquaSolv omni biorefinery for lignin using Bayesian optimization, a machine learning framework sample-efficient guided data collection. This tool allows us relate conditions like hydrothermal pretreatment reaction severity temperature multiple experimental outputs, such as structural features characterized 2D nuclear magnetic resonance spectroscopy. By applying Pareto front analysis our models, can find processing that simultaneously optimize yield amount β-O-4 linkages depolymerization into platform chemicals. Our study demonstrates potential accelerate development sustainable chemical techniques targeted applications products.

Geometric Optimization in Machine Learning

Machine learning models often rely on sparsity, low-rank, orthogonality, correlation, or graphical structure. The structure of interest in this chapter is geometric, specifically the manifold of positive definite (PD) matrices. Though these matrices recur throughout the applied sciences, our focus is on more recent developments in machine learning and optimization. In particular, we study (i) m...

Tractable Optimization in Machine Learning

Machine Learning (ML) broadly encompasses a variety of adaptive, autonomous, and intelligent tasks where one must “learn” to predict from observations and feedback. Throughout its evolution, ML has drawn heavily and successfully on optimization algorithms. This relation to optimization is not surprising as “learning” and “adapting” usually lead to problems where some quality function must be op...
