Finding repeated patterns or motifs in a time series is an important unsupervised task that has still a number of open issues, starting by the definition of motif. In this paper, w…
Ranking and significance of variable-length similarity-based time series motifs
Joan Serrà, Isabel Serra, Álvaro Corral +1
The detection of very similar patterns in a time series, commonly called motifs, has received continuous and increasing attention from diverse scientific communities. In particular…
Particle swarm optimization for time series motif discovery
Joan Serrà, Josep Lluis Arcos
Efficiently finding similar segments or motifs in time series data is a fundamental task that, due to the ubiquity of these data, is present in a wide range of domains and situatio…
An Empirical Evaluation of Similarity Measures for Time Series Classification
Joan Serrà, Josep Lluis Arcos
Time series are ubiquitous, and a measure to assess their similarity is a core part of many computational systems. In particular, the similarity measure is the most essential ingre…
