Several methods have been proposed for time series alignment and classification.In particular our previously published method I-SEA (Improved Shape Exchange Algorithm) has been proposed as a rival method to the SEA (Shape Exchange Algorithm) method for time series alignment.The aim of this work is to improve the accuracy of the SEA method for time series classification by proposing a 1NN-ISEA (1 Nearest Neighbor-Improved Shape Exchange Algorithm) classifier.Results of the proposed method show to be better as compared to those of the 1NN-SEA and the 1NN-ED classifiers (Euclidian Distance).All results have been obtained using the UCR (University of California at Riverside) time series Dataset, universally admitted as the first Benchmark in time series classification and clustering.
