FFCBS: a simple similarity measurement for time series

Abstract

This paper introduces a new idea FFCBS, on time series distance measurement, which cares the cost that transforms one series to another one. The operation cost of amplitude scaling, y-axis shifting, are introduced into our FFCBS, to give a simple distance definition. Furthermore, c fast simple time warping method is proposed to deal with the dyerent time series of different lengths, to make FFCBS more applicable. With these set-up models. a time series extrapolation solution is given, followed by discussion of several issues. Experimental result shows that our approach is rather fast and more reasonable.
