CDPS: Constrained DTW-Preserving Shapelets
, 2023 The analysis of time series for clustering and classificationis becoming ever more popular because of the increasingly ubiquitousnature of IoT, satellite constellations, and handheld and smart-wearabledevices, etc. The presence of phase shift, differences in sample dura-tion, and/or compression and dilation of a signal means that Euclideandistance is ...

Dynamic Time Warping of Pulse Wave Curves
Current Directions in Biomedical Engineering, 2018 Being able to non-obtrusively and continuously monitor arterial blood pressure is of great interest, particularly in the context of wearable sensors. A common limitation is the need for dedicated hardware, which is either obtrusive or expensive.

Pattern matching under DTW distance
, 2022 In this work, we consider the problem of pattern matching under the dynamic time warping (DTW) distance motivated by potential applications in the analysis of biological data produced by the third generation sequencing. To measure the DTW distance between two strings, one must "warp" them, that is, double some letters in the strings to obtain two equal-

Improving the efficiency of traditional DTW accelerators [PDF]
Knowledge and Information Systems, 2013 Dynamic Time Warping (DTW) is the most popular approach for evaluating the similarity of time series, but its computation is costly. Therefore, simple functions lower bounding DTW distances have been designed, accelerating searches by quickly pruning sequences that could not possibly be best matches.

Uncertainty-DTW for Time Series and Sequences
, 2022 Dynamic Time Warping (DTW) is used for matching pairs of sequences and celebrated in applications such as forecasting the evolution of time series, clustering time series or even matching sequence pairs in few-shot action recognition. The transportation plan of DTW contains a set of paths; each path matches frames between two sequences under a varying ...

Character Recognition Based on DTW-Radon [PDF]
2011 International Conference on Document Analysis and Recognition, 2011 The paper presents a method for isolated off-line character recognition using radon features. The key characteristic of the method is to use DTW algorithm to match corresponding pairs of radon histograms at every projecting angle. Thanks to DTW, it avoids compressing feature matrix into a single vector which may miss information.

Time Series Retrieval Using DTW-Preserving Shapelets [PDF]
, 2018 Dynamic Time Warping (DTW) is a very popular similarity measure used for time series classification, retrieval or clustering. DTW is, however, a costly measure, and its application on numerous and/or very long time series is difficult in practice. This paper proposes a new approach for time series retrieval: time series are embedded into another space ...
