INCREASING THE PREDICTION ACCURACY OF PLANT OIL PRODUCTION PROCESSES THROUGH ADJUSTING THE PARAMETERS OF MACHINE LEARNING MODELS
Аннотация
Vegetable oil production is characterized by high variability in output indicators due to nonlinear interactions between raw material parameters, equipment modes, and heat and mass transfer conditions. Existing approaches to applying machine learning in this field, as a rule, do not account for the impact of hyperparameter adjustments on forecasting quality across specific technological stages. The article presents a systematic methodology for adjusting model parameters (Ridge regression, SVR, GBM, LSTM) applied to three key tasks: predicting residual oil content in oil cake, color index during bleaching, and free fatty acid content during deodorization. In a set of 1000 observations, including technological, energy, and laboratory indicators, it is shown that adjusting hyperparameters improves forecast quality compared to basic model configurations; the best results were obtained for Gradient Boosting and LSTM.
