A mathematical model was developed to predict lignocellulosic biomass structural components, integrating self-organizing maps (SOMs) and regression models for more accurate results, clustering data into 4 groups. Each group showed distinct characteristics, and the regression model pre-analyzed by SOMs outperformed the model without pre-analysis. The model can be applied to biomass characterization and utilization research.
In order to reduce time and resource consumption, the mathematical model was developed to predict lignocellulosic biomass structural components including cellulose, hemicellulose and lignin from ultimate/proximate dataset. Self-organizing maps (SOMs) were integrated with a regression model to obtain more precise results than the procedure without data clustering. In SOMs, the 149-biomass dataset from literatures, expressed by the ratios of VM/C, VM/H, VM/O, FC/C, FC/H, FC/O and ASH/O, were employed for training and clustered into 4 groups. The result indicated that each group had its own characteristics. The regression model with pre-analyzed by SOMs provided better results compared to the model without pre-analyzed by SOMs. The model obtained in this study can be applied to further researches in many fields; e.g. biomass characterization and utilization. ? 2021 Elsevier Ltd.
