Segmental Dtw: A Parallelizable Alternative to Dynamic Time Warping

ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
In this work we explore parallelizable alternatives to DTW for globally aligning two feature sequences. One of the main practical limitations of DTW is its quadratic computation and memory cost. Previous works have sought to reduce the computational cost

Improvement of Dynamic Time Warping (DTW) Algorithm

2015 14th International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES), 2015
Dynamic time warping algorithm is widely used in similar search of time series. However, large scales of route search in existing algorithms resulting in low operational efficiency. In order to improve the efficiency of dynamic time warping algorithm, this paper put forward an improved algorithm, which plans out a three rectangular area in the search ...

Quantized Dynamic Time Warping (DTW) algorithm

2010 8th International Conference on Communications, 2010
DTW algorithm compares the parameters of an unknown spoken word with the parameters of one or more reference templates. The more reference templates are used for the same word, the higher is the recognition rate. But increasing the number of reference templates for the same word to recognize, leads to an increase in memory resources and computing time.

Fault detection using dynamic time warping (DTW) algorithm and discriminant analysis for swine wastewater treatment.

Journal of Hazardous Materials, 2011
This paper proposes a diagnosis system using dynamic time warping (DTW) and discriminant analysis with oxidation-reduction potential (ORP) and dissolved oxygen (DO) values for swine wastewater treatment. A full-scale sequencing batch reactor (SBR), which has an effective volume of 20 m(3), was auto-controlled, and the reaction phase was performed by a ...
