Witryna7 sty 2024 · It seems that these three methods can improve the forecasting quality for coking coal freight transportation. To forecast export and domestic transportation of coking coal, we built optimal ensembles of ElacticNet, LightGBM, and Facebook Prophet as the final models. 3.3 Forecasting Quality Measurement Witryna2 sty 2024 · LightGBM is a Machine Learning library that uses Gradient Boosting on Decision Trees. Let me explain. Gradient Boosting is an ensemble method. It assembles several Machine Learning algorithms to obtain a prediction on a dataset. Since we use multiple algorithms, the result is more reliable than if we used only one.
