We present a modern review on forecast combinations over the past five decades
Title: Forecast combinations: An over 50-year review Authors: Xiaoqian Wang, Rob J. Hyndman, Feng Li and Yanfei Kang Journal: International Journal of Forecasting Summary: The idea of combining multiple individual forecasts dates back to Francis Galton, who in 1906 visited an ox-weight-judging competition and observed that the average of 787 estimates of an ox’s weight…

Paper “Feature-based intermittent demand forecast combinations: accuracy and inventory implications” appeared in International Journal of Production Research
Authors: Li Li, Yanfei Kang, Fotios Petropoulos and Feng Li Links: [ DOI | Preprint ] Summary: Intermittent demand with several periods of zero demand is ubiquitous in practice. Over half of inventory consists of spare parts, in which demand is typically intermittent (Nikolopoulos Citation2021). Given the high purchase and shortage costs associated with intermittent demand…

New Paper: “Optimal reconciliation with immutable forecasts” appeared in European Journal of Operational Research
Authors: Bohan Zhang, YanfeiKang, AnastasiosPanagiotelis, FengLi Journal: European Journal of Operational Research Links: [ DOI | Preprint | Python code ] Summary: In this paper, we propose a forecast reconciliation approach that can keep the base forecasts of specific levels or multiple nodes from different levels immutable after reconciliation. The proposed method is flexible and…

The febama paper is published in the International Journal of Forecasting
Authors: Li Li, Yanfei Kang, Feng Li Summary: Achieving a robust and accurate forecast is a central focus in finance and econometrics. Forecast combination has been adopted as an essential enhancement tool for improving time series forecasting performance during recent decades (Bergmeir et al., 2016, Garratt et al., 2019, Kolassa, 2011), due to its ability to reduce the…

New paper “Escalator accident mechanism analysis and injury prediction approaches in heavy capacity metro rail transit stations” published in Safety Science
Authors: Zhiru Wang, Yu Pang, Mingxin Gan, Martin Skitmore, Feng Li Link: https://doi.org/10.1016/j.ssci.2022.105850 Summary: The semi-open character with high passenger flow in Metro Rail Transport Stations (MRTS) makes safety management of human-electromechanical interaction escalator systems more complex. Safety management should not consider only single failures, but also the complex interactions in the system. This study…

Paper accepted in IJF: Hierarchical forecasting with a top-down alignment of independent level forecasts
Authors: Matthias Anderer and Feng Li Abstract: Hierarchical forecasting with intermittent time series is a challenge in both research and empirical studies. Extensive research focuses on improving the accuracy of each hierarchy, especially the intermittent time series at bottom levels. Then hierarchical reconciliation could be used to improve the overall performance further. In this paper, we present…
