\subsection{Demand Forecasting with Machine Learning Methods}
|
||||
\label{ml_methods}
|
||||
|
||||
ML methods have been employed in all kinds of prediction tasks in recent
|
||||
years.
|
||||
In this section, we restrict ourselves to the models that performed well in
|
||||
our study: Random Forest (\gls{rf}) and Support Vector Regression
|
||||
(\gls{svr}).
|
||||
RFs are in general well-suited for datasets without a priori knowledge about
|
||||
the patterns, while SVR is known to perform well on time series data, as
|
||||
shown by \cite{hansen2006} in general and \cite{bao2004} specifically for
|
||||
intermittent demand.
|
||||
Gradient Boosting, another popular ML method, was consistently outperformed by
|
||||
RFs, and artificial neural networks require an amount of data
|
||||
exceeding what our industry partner has by far.
