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.

Malaysia PM10 Air Quality Time Series Clustering Based on Dynamic Time Warping

open access: yesAtmosphere, 2022
Air quality monitoring is important in the management of the environment and pollution. In this study, time series of PM10 from air quality monitoring stations in Malaysia were clustered based on similarity in terms of time series patterns.

Feature trajectory dynamic time warping for clustering of speech segments [PDF]

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2019
Dynamic time warping (DTW) can be used to compute the similarity between two sequences of generally differing length. We propose a modification to DTW that performs individual and independent pairwise alignment of feature trajectories.

Weakly Supervised Temporal Anomaly Segmentation with Dynamic Time Warping [PDF]

open access: greenIEEE International Conference on Computer Vision, 2021
Most recent studies on detecting and localizing temporal anomalies have mainly employed deep neural networks to learn the normal patterns of temporal data in an unsupervised manner. Unlike them, the goal of our work is to fully utilize instance-level (or

Computing and Visualizing Dynamic Time Warping Alignments in R: The dtw Package [PDF]

open access: yesJournal of Statistical Software, 2009
Dynamic time warping is a popular technique for comparing time series, providing both a distance measure that is insensitive to local compression and stretches and the warping which optimally deforms one of the two input series onto the other.

Head Gesture Recognition Combining Activity Detection and Dynamic Time Warping [PDF]

open access: yesJournal of Imaging
The recognition of head movements plays an important role in human–computer interface domains. The data collected with image sensors or inertial measurement unit (IMU) sensors are often used for identifying these types of actions.
