WebAn idSupportVectormachine object implements a support vector machine (SVM) regression model, and is a nonlinear mapping function for estimating nonlinear ARX models. This mapping object, which is also referred to as a nonlinearity, incorporates objects that the mapping function creates using Statistics and Machine Learning Toolbox™ functions. WebThe ARX model name stands for Autoregressive with Extra Input, because, unlike the AR model, the ARX model includes an input term. ARX is also known as Autoregressive with Exogenous Variables, where the exogenous variable is the input term.
