EFFECTS OF PARAMETER SELECTION ON FORECAST ACCURACY AND EXECUTION TIME IN NONPARAMETRIC REGRESSION

In this paper, the authors discuss how nonparametric regression can be used to accurately forecast short term traffic flow. They first describe how nonparametric regression is a forecasting technique based on nearest neighbor searching in which forecasts are derived from previous observations that are similar to current conditions. They then discuss how the execution time of the nearest neighbor nonparametric regression can be achieved through advance data structures. They also offer that further reductions may be achieved by using approximate nearest neighbors, although this leads to a reduction forecast accuracy.
