With high precision, DTW is one of the most prevalent similarity measures for time series [1], [4], [7], [17]. However, the computational complexity of DTW is O(n2), which greatly limits its application to the high dimensional time series and the dynamic data stream. Many methods have...
Finally, the third challenge addresses the similarity measures that are used to make the clusters. To do so, similar time-series should be found which needs time-series similarity matching that is the process of calculating the similarity among the whole time-series using a similarity measure. ...

1.An efficient lower bounding technique is proposed based on Dynamic Time Warping(DTW) for time series similarity search,which measures the distance between original sequence reduced dimensionality by Piecewise Aggregate Approximation(PAA) approximation method and query sequence reduced dimensionality by Grid...
The processing phase described in the paper can be divided into two operations: (1) time-series clustering and (2) time-series prediction/forecasting. Clustering aims at creating groups of time-series based on some similarity measures. As the different time-series correspond to vertical displacement...
We present a new way to find clusters in large vectors of time series by using a measure of similarity between two time series, the generalized cross correlation. This measure compares the determinant of the correlation matrix until some lagkof the bivariate vector with those of the two univaria...
