An inner-product lower-bound estimate for dynamic time warping

Abstract

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-bound estimate based on the inner-product distance that has been found to be an effective metric for computing similarities between posteriorgrams. In… (More)
