- Abstract: Forecasting is challenging since uncertainty resulted from exogenous factors
exists. This work investigates the rank position forecasting problem in car
racing, which predicts the rank positions at the future laps for cars. Among
the many factors that bring changes to the rank positions, pit stops are
critical but irregular and rare. We found existing methods, including
statistical models, machine learning regression models, and state-of-the-art
deep forecasting model based on encoder-decoder architecture, all have
limitations in the forecasting. By elaborative analysis of pit stops events, we
propose a deep model, RankNet, with the cause effects decomposition that
modeling the rank position sequence and pit stop events separately. It also
incorporates probabilistic forecasting to model the uncertainty inside each
sub-model. Through extensive experiments, RankNet demonstrates a strong
performance improvement over the baselines, e.g., MAE improves more than 10%
consistently, and is also more stable when adapting to unseen new data. Details
of model optimization, performance profiling are presented. It is promising to
provide useful forecasting tools for the car racing analysis and shine a light
on solutions to similar challenging issues in general forecasting problems.
