“…Thus MARS has been widely used in various fields such as sales prediction [52], credit evaluation [53][54][55], stock price forecasting [56][57][58], software reliability analysis [59][60][61] and predicting species distribution [62,63]. However, MARS has been rarely used in port throughput forecasting in the existing literature; therefore, this paper employs MARS to determine the final input vectors for RSVR and analyze significance degrees between different factors for further port throughput generation mechanism research.…”

“…Additionally, since the radial basis function (RBF) is the most widely used kernel function [36], this study uses it for our experimental study. The RBF can be defined as follows: ϕ(xi,xj)=exp(||xixj||22σ2), where σ denotes the width of the RBF.…”

“…In this study, we use the mean absolute percentage error (MAPE), root mean square error (RMSE), and mean absolute difference (MAD) to measure the prediction capability of the models. These prediction measurements are defined as follows [26]:…”

“…The explanatory variables for the models included installed capacity, gross electricity generation, population, and the total number of customers. However, ANN has been criticized for its long training process when designing the optimal structure [25,26].In recent years, hybrid forecasting models with feature selection techniques (FSTs) have been studied for electricity sales forecasting. A hybrid model with fast ensemble empirical mode decomposition, variational mode decomposition, and ANN was investigated in forecasting electricity prices [27].…”
