Efficient search of the best warping window for Dynamic Time Warping [PDF]

open access: bronze, 2018
Time series classification maps time series to labels. The nearest neighbor algorithm (NN) using the Dynamic Time Warping (DTW) similarity measure is a leading algorithm for this task and a component of the current best ensemble classifiers for time series.

Similarity join over multiple time series under Dynamic Time Warping

open access: yesCTU Journal of Innovation and Sustainable Development, 2023
Similarity join over multiple time series is an interesting task of data mining. This task aims at identifying couples of similar subsequences from multiple time series and the two subsequences might have any length and be at any position in the time ...

Efficient Time Series Clustering by Minimizing Dynamic Time Warping Utilization

open access: yesIEEE Access, 2021
Dynamic Time Warping (DTW) is a widely used distance measurement in time series clustering. DTW distance is invariant to time series phase perturbations but has a quadratic complexity.

Improved LDTW Algorithm Based on the Alternating Matrix and the Evolutionary Chain Tree

open access: yesSensors, 2022
Dynamic time warping under limited warping path length (LDTW) is a state-of-the-art time series similarity evaluation method. However, it suffers from high space-time complexity, which makes some large-scale series evaluations impossible.

Seeded Classification of Satellite Image Time Series with Lower-Bounded Dynamic Time Warping

open access: yesRemote Sensing, 2022
Satellite Image Time Series (SITS) record the continuous temporal behavior of land cover types and thus provide a new perspective for finer-grained land cover classification compared with the usual spectral and spatial information contained in a static ...

Voice Transformation Using Two-Level Dynamic Warping and Neural Networks

open access: yesSignals, 2021
Voice transformation, for example, from a male speaker to a female speaker, is achieved here using a two-level dynamic warping algorithm in conjunction with an artificial neural network.

Learning Discriminative Prototypes with Dynamic Time Warping [PDF]

open access: yes2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
Dynamic Time Warping (DTW) is widely used for temporal data processing. However, existing methods can neither learn the discriminative prototypes of different classes nor exploit such prototypes for further analysis. We propose Discriminative Prototype DTW (DP-DTW), a novel method to learn class-specific discriminative prototypes for temporal ...

Pairwise dynamic time warping for event data [PDF]

open access: yesComputational Statistics & Data Analysis, 2014
We introduce a new version of dynamic time warping for samples of observed event times that are modeled as time-warped intensity processes. Our approach is devel- oped within a framework where for each experimental unit or subject in a sample, one observes a random number of event times or random locations.
