Enhancing Nearest Neighbor Classification Performance through Dynamic Time Warping with Progressive Constraint

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
Dynamic time warping (DTW) is a widely used metric for comparing time series data, offering elasticity in alignment. While the original DTW allows infinite elasticity without penalty, the wDTW imposes a constant penalty regardless of elastic length.

Subsequence Join in Streaming Time Series under Dynamic Time Warping

open access: yesVietnam Journal of Computer Science
Subsequence join in time series is to search for couples of similar subsequences from multiple time series. The task is useful in data mining on time series; nevertheless, it is extremely difficult because of its enormous computational cost.

Efficient alignment-based average delay time estimation in fluctuating delayed propagation

open access: yesArray, 2022
We propose an alignment-based average delay time estimation algorithm between two time series in the propagation of time-varying delay. Though the number of the minimum cost alignments may be exponential in the length of the time series, the proposed ...

Online coherence identification using dynamic time warping for controlled islanding

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
Controlled islanding is considered to be the last countermeasure to prevent a system-wide blackout in case of cascading failures. It splits the system into self-sustained islands to maintain transient stability at the expense of possible loss of load ...

Co-movement of Commodity Prices - Results from Dynamic Time Warping Classification

open access: yesZeszyty Naukowe Uniwersytetu Ekonomicznego w Krakowie, 2015
Several factors are responsible for difficulties in describing the behaviour of commodity prices. Firstly, there are numerous different categories of commodities. Secondly, some categories overlap with other categories, while others indirectly compete in

Evaluation of Paleocene‐Eocene Thermal Maximum Carbon Isotope Record Completeness—An Illustration of the Potential of Dynamic Time Warping in Aligning Paleo‐Proxy Records

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Variations in sedimentation rate, bioturbation, winnowing, and dissolution modify the deep‐sea sedimentary record, complicating the apparent relationship between stratigraphic depth and time of a geochemical proxy record and confounding the extraction of

On the Distribution of Muscle Signals: A Method for Distance-Based Classification of Human Gestures

open access: yesSensors, 2023
We investigate the distribution of muscle signatures of human hand gestures under Dynamic Time Warping. For this we present a k-Nearest-Neighbors classifier using Dynamic Time Warping for the distance estimate.

Covariance Features for Trajectory Analysis

open access: yesElektronika ir Elektrotechnika, 2018
In this work, it is demonstrated that covariance estimator methods can be used for trajectory classification. It is shown that, features obtained via shrunk covariance estimation are suitable for describing trajectories. Compared to Dynamic Time Warping,
