The state saving mechanism constitutes an essential part of any system in which erroneous or undesired executions can be undone by rolling back the system state. One such application is optimistically synchronized parallel discrete event simulation (PDES) systems based on the Time Warp Synchronization mechanism. In this type of systems the state saving and restoration mechanism is essential to ...

This paper presents a novel algorithm that has been specifically designed for the recognition of multivariate temporal musical gestures. The algorithm is based on Dynamic Time Warping and has been extended to classify any N dimensional signal, automatically compute a classification threshold to reject any data that is not a valid gesture and be quickly trained with a low number of training exam...

This paper presents the use of Dynamic Time Warping (DTW) for measuring prosodic differences between variable-sized sentences. This methodological study may apply to various prosodic functions, accented or expressive speech. Both the structuring and attitudinal functions of prosody are investigated here. We evaluated the relevance of three prosodic (dis)similarity measures to account for percei...

In this project we use supervised learning to develop a classifier for stellar lightcurves to detect whether they demonstrate the existence of exosolar planets. We use various features selection methods; in particular we will be using dynamic time warping to measure the similarity between two temporal sequences.

The primary system we submitted was composed of 11 subsystems as the required run. 3 subsystems are based on Acoustic Keyword Spotting (AKWS) and 8 on Dynamic Time Warping (DTW). The AKWS systems were based only on phoneme posteriors while the DTW subsystems were based on both phoneme posteriors and Bottle-Neck features (BN) as input. The underlying phoneme posterior estimators / bottle-neck fe...

Music alignment is the association of events in a score with points in the time axis of an audio signal. The signal is thus segmented according to the events in the score. We propose a new methodology for automatic alignment based on dynamic time warping, where the spectral peak structure is used to compute the local distance, enhanced by a model of attacks and of silence. The methodology can c...

Advancing the automatic synthesis of linguistically accurate and natural-looking American Sign Language (ASL) animations from an easy-to-update script would increase information accessibility for many people who are deaf by facilitating more ASL content to websites and media. We are investigating the production of ASL grammatical facial expressions and head movements coordinated with the manual...
