FAST SPOKEN QUERY DETECTION USING LOWER-BOUND DYNAMIC TIME WARPING ON GRAPHICAL PROCESSING UNITS
spoken term detection GPU dynamic time warping CUDA
2014/11/27
In this paper we present a fast unsupervised spoken term detection system based on lower-bound Dynamic Time Warping (DTW) search on Graphical Processing Units (GPUs). The lower-bound estimate and the ...
AN INNER-PRODUCT LOWER-BOUND ESTIMATE FOR DYNAMIC TIME WARPING
dynamic time warping posteriorgram
2014/11/27
In this paper, we present a lower-bound estimate for dynamic time warping (DTW) on time series consisting of multi-dimensional posterior probability vectors known as posteriorgrams. We develop a lower...
