Improving N-Glycosylation and Biopharmaceutical Production Predictions Using AutoML-Built Residual Hybrid Models

Pedro Seber, Richard Braatz

Abstract: N-glycosylation has many essential biological roles, and is important for biotherapeutics as it can affect drug efficacy, duration of effect, and toxicity. The prediction of N-glycosylation and other important biopharmaceutical production values have mostly been limited to mechanistic modeling. We present a residual hybrid modeling approach that integrates mechanistic modeling with machine learning to produce significantly more accurate predictions for N-glycosylation and bioproduction. For the largest dataset, the residual hybrid models have an average 736-fold reduction in testing prediction error. Furthermore, the residual hybrid models have lower prediction errors than the mechanistic models for all of the predicted variables in the datasets. We provide the automatic machine learning software used in this work, allowing reproduction and use of our software for other tasks.
