R package for Time-Weighted Dynamical Time Warping (TWDTW)

We have produced dtwSat , an R package that implements the time-weigthed dynamic time warping algorithm. The method improves on the well-known dynamical time warping (DTW) method for time series data mining. We introduce a temporal constraint that accounts for the agricultural calendar. The resulting algorithm achives better results than previous research that has used DTW for remote sensing image classification. The package is fully described in a paper on the Journal of Statistical software .
