Ranking and significance of variable-length similarity-based time series motifs

no code implementations6 Mar 2015 Joan Serrà, Isabel Serra, Álvaro Corral, Josep Lluis Arcos

Specifically, we find that length-normalized motif dissimilarities still have intrinsic dependencies on the motif length, and that lowest dissimilarities are particularly affected by this dependency.
