Exploring Worm Behaviors using DTW
Proceedings of the 7th International Conference on Security of Information and Networks, 2014Worms 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

New parallel implementations for DTW algorithms
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990The parallel realization of a popular dynamic time warping (DTW) algorithm is discussed. Two alternative techniques are proposed, one based on a circular array and the other using a linear array of processing elements (PEs). The architecture of each PE is defined in both cases and computational phases are outlined.

Abstract In general, the inter-word dissimilarity measure supplied by Dynamic Time Warping algorithms can not be assumed to be a metric because it does not fully satisfy all the required properties (the triangle inequality in particular). In this paper, however, empirical evidence of loose satisfaction of these properties with real speech will be ...

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

Optimization of VLSI architectures for DTW
2012 7th International Conference on Electrical and Computer Engineering, 2012In 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.

A combined filtering search for DTW
2017 2nd International Conference on Image, Vision and Computing (ICIVC), 2017Due to its high matching precision, DTW is an important similarity measure for time series. However, the high computational complexity restricts its application on mass data sets. To solve the problem, a combined filtering search is proposed, which combines lower-bounding technique and early-abandon strategy, to reduce the redundant computation.

Proceedings of the 19th ACM SIGKDD international conference on Knowledge discovery and data mining, 2013
Classification of time series data is an important problem with applications in virtually every scientific endeavor. The large research community working on time series classification has typically used the UCR Archive to test their algorithms. In this work we argue that the availability of this resource has isolated much of the research community from

Enhanced DTW based on-line signature verification
2009 16th IEEE International Conference on Image Processing (ICIP), 2009This work describes an enhanced technique for on-line signature verification. The distance between two signatures is computed by dynamic time warping (DTW) method. The reference signatures are used to assign special parameters for each signer, which makes the system cover the intra signer variation. Several features are extracted.

Hand Gestures Classification with Multi-Core DTW.
ISC Int. J. Inf. Secur., 2019Classifications of several gesture types are very helpful in several applications. This paper tries to address fast classifications of hand gestures using DTW over multi-core simple processors. We presented a methodology to distribute templates over multi-cores and then allow parallel execution of the classification.
