Query: COSTI: a New Classifier for Sequences of Temporal Intervals   Classification of sequences of temporal intervals is a part of time series
analysis which concerns series of events. We propose a new method of
transforming the problem to a task of multivariate series classification. We
use one of the state-of-the-art algorithms from the latter domain on the new
representation to obtain significantly better accuracy than the
state-of-the-art methods from the former field. We discuss limitations of this
workflow and address them by developing a novel method for classification
termed COSTI (short for Classification of Sequences of Temporal Intervals)
operating directly on sequences of temporal intervals. The proposed method
remains at a high level of accuracy and obtains better performance while
avoiding shortcomings connected to operating on transformed data. We propose a
generalized version of the problem of classification of temporal intervals,
where each event is supplemented with information about its intensity. We also
provide two new data sets where this information is of substantial value.
