CS-DTW

Proceedings of the 5th Symposium on Spatial User Interaction, 2017
We present an open-source implementation of multivariate subsequence Dynamic Time Warping (DTW) on GPU compute shaders (CS-DTW). Our implementation allows for real-time matching of a multivariate spatial input against thousands of pre-recorded templates. We show that, for template matching, CS-DTW is orders of magnitude faster than the state-of-the-art

Exploring Worm Behaviors using DTW

Proceedings of the 7th International Conference on Security of Information and Networks, 2014
Worms are becoming a potential threat to Internet users across the globe. The financial damages due to computer worms increased significantly in past few years. Analyzing these hazardous worm attacks has become a crucial issue to be addressed. Given the fact that worm analysts would prefer to analyze classes of worms rather than individual files, their

Systolic multiple-valued DTW processor

1991 International Conference on Circuits and Systems, 2002
A new concept called 'recursive systolic flow' is proposed in this paper. It is adaptable to the formal algebraic design for complex systolic algorithm. A new systolic multiple-valued DTW (MV-DTW) processor is also presented which can achieve real-time isolated word recognition for large dictionaries.

Unsupervised study of plethysmography signals through DTW clustering

2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022
The study of plethysmography time series is crucial to better understand the breathing behavior of mice, in particular the influence of neurotoxins on the respiratory system. Current approaches rely on a few respiratory descriptors computed on individual breathing cycles that fail to account for the variety of breathing habits and their evolution with ...

Optimization of VLSI architectures for DTW

2012 7th International Conference on Electrical and Computer Engineering, 2012
In data mining and time series recognition applications Dynamic Time Warping (DTW) is a very popular method. It can produce accurate results provided its originality is preserved. But its lethargic nature has been inspiring development of its hardware based acceleration methods.

Speech recognition using MFCC and DTW

2014 International Conference on Advances in Electrical Engineering (ICAEE), 2014
Speech recognition has wide range of applications in security systems, healthcare, telephony military, and equipment designed for handicapped. Speech is continuous varying signal. So, proper digital processing algorithm has to be selected for automatic speech recognition system. To obtain required information from the speech sample, features have to be

Human Activity Recognition using DTW Algorithm

2019 IEEE Region 10 Symposium (TENSYMP), 2019
Human activity recognition is now a well-known field of Human Computer Interaction (HCI) because of its capability to provide personalized support using different applications. For the purpose of recognizing human activities, we selected three activities (running, walking, and steady state, e.g., sitting and lying).
