On Forecast Stability

no code implementations26 Oct 2023 Rakshitha Godahewa, Christoph Bergmeir, Zeynep Erkin Baz, Chengjun Zhu, Zhangdi Song, Salvador García, Dario Benavides

To fill this gap, we propose a simple linear-interpolation-based approach that is applicable to stabilise the forecasts provided by any base model vertically and horizontally.

Handling Concept Drift in Global Time Series Forecasting

1 code implementation4 Apr 2023 Ziyi Liu, Rakshitha Godahewa, Kasun Bandara, Christoph Bergmeir

Handling concept drift in forecasting is essential for many ML methods in use nowadays, however, the prior work only proposes methods to handle concept drift in the classification domain.

SETAR-Tree: A Novel and Accurate Tree Algorithm for Global Time Series Forecasting

1 code implementation16 Nov 2022 Rakshitha Godahewa, Geoffrey I. Webb, Daniel Schmidt, Christoph Bergmeir

On the other hand, in the forecasting community, general-purpose tree-based regression algorithms (forests, gradient-boosting) have become popular recently due to their ease of use and accuracy.

Ensembles of Localised Models for Time Series Forecasting

1 code implementation30 Dec 2020 Rakshitha Godahewa, Kasun Bandara, Geoffrey I. Webb, Slawek Smyl, Christoph Bergmeir

With large quantities of data typically available nowadays, forecasting models that are trained across sets of time series, known as Global Forecasting Models (GFM), are regularly outperforming traditional univariate forecasting models that work on isolated series.

Seasonal Averaged One-Dependence Estimators: A Novel Algorithm to Address Seasonal Concept Drift in High-Dimensional Stream Classification

1 code implementation27 Jun 2020 Rakshitha Godahewa, Trevor Yann, Christoph Bergmeir, Francois Petitjean

This paper explores how to best handle seasonal drift in the specific context of news article categorization (or classification/tagging), where seasonal drift is overwhelmingly the main type of drift present in the data, and for which the data are high-dimensional.
