Abstract:Time-series forecasting is an area of machine learning that can be applied to many real-life problems. It is used in areas such as water level forecasting, which aims to help people evacuate on time for floods. This thesis aims to contribute to the research area of time series forecasting, by introducing a simple but novel ensemble model: Force Linear to Exponential (FLEX). A FLEX ensemble first forecasts points that are exponentially further into the forecasting horizon. After this, the gaps between forecasted points are produced from said forecasted points, as well as the entire data history. This simple model is able to outperform all base models considered in this thesis, even when having the same amount of parameters to tune.
