The 11 full papers presented were carefully reviewed and selected from 22 submissions. The first part focuses on learning new representations and embeddings for time series classification, clustering or for dimensionality reduction. The second part presents approaches on classification and clustering with challenging applications on medicine or earth observation data. These works show different ways to consider temporal dependency in clustering or classification processes. The last part of the book is dedicated to metric learning and time series comparison, it addresses the problem of speeding-up the dynamic time warping or dealing with multi-modal and multi-scale metric learning for time series classification and clustering Notes Includes author index Bibliography Includes bibliographical references and index Notes Online resource; title from PDF title page (SpringerLink, viewed August 12, 2016) Subject Time-series analysis -- Data processing -- Congresses Machine learning -- Congresses Temporal databases -- Congresses Databases.
