The Long and Winding Road: The Story of Complex Exponential Smoothing

About the paper. Disclaimer The idea of using complex variables in modelling and forecasting was originally proposed by my father, Sergey Svetunkov. Based on that, we developed several models, which were then used in some of our research. We worked together in this direction and published several articles in Russian. My father even published a … Read more

A simple combination of univariate models

Fotios Petropoulos and I have participated last year in M4 competition. Our approach performed well, finishing as 6th in the competition. This paper in International Journal of Forecasting explains what we used in our approach and why. Here’s the abstract: This paper describes the approach that we implemented for producing the point forecasts and prediction … Read more

Complex Exponential Smoothing (Working paper)

Some time ago I have published the working paper on Complex Exponential Smoothing on ResearchGate website. This is the paper written by Nikolaos Kourentzes and I in 2015. It explains a new approach in time series modelling and in forecasting, based on a notion of “information potential”. The model, resulting from this idea, allows to … Read more

Presentation on Management Science seminar at Lancaster University

Today I have given a presentation on the topic of Complex Exponential Smoothing on Management Science seminar at Lancaster University. Lecturers and PhD students of the department attended the presentation and seemed to like it. However, only in the morning of the day I realised that I have prepared a wrong presentation (it should have … Read more
