Time series overfitting
WebApr 12, 2024 · Since problems like underfitting, overfitting, and misspecification can result in a system with low accuracy or even deteriorate the linear forecast of the time series, the selection, specification, and training of one ML model to forecast the residuals are tasks that are both challenging and expensive to complete. WebFeb 20, 2024 · The causes of overfitting are the non-parametric and non-linear methods because these types of machine learning algorithms have more freedom in building the model based on the dataset and therefore …
