One of the most prominent problems in the area of time series data mining is called supervised time series clasication. The goal of this problem is to build a model that predicts the classes of new unclassied series as accurately as possible, departing from a database of time series for which the class is known. As an extension of this problem, on some occasions, the data is collected over time, and, in order to avoid costs that incur in collecting new data or negative consequences that may arise when making late predictions, the goal is to make the class predictions as early as possible. In this context, the problem denominated early classication of time series arises, whose objective is to build a classier that is as accurate as possible,...
