ABSTRACT
A method for approximate subsequence matching is introduced,
that significantly improves the efficiency of subsequence match-
ing in large time series data sets under the dynamic time warping
(DTW) distance measure. Our method is called EBSM, shorthand
for Embedding-Based Subsequence Matching. The key idea is to
