Center node: "time series kernel similarities for predicting paroxysmal atrial fibrillation from ecgs"
  Abstract: We tackle the problem of classifying Electrocardiography (ECG) signals with the aim of predicting the onset of Paroxysmal Atrial Fibrillation (PAF). Atrial fibrillation is the most common type of arrhythmia, but in many cases PAF episodes are asymptomatic. Therefore, in order to help diagnosing PAF, it is important to be design a suitable procedure for detecting and, more importantly, predicting PAF episodes. We propose a method for predicting PAF events whose first step consists of a feature extraction procedure that represents each ECG as a multi-variate time series. Successively, we design a classification framework based on kernel similarities for multi-variate time series, capable of handling missing data. We consider different approaches to perform classification in the original space of the multi-variate time series and in an embedding space, defined by the kernel similarity measure. Our classification results show state-of-the-art performance in terms of accuracy. Furthermore, we demonstrate the ability to predict, with high accuracy, the PAF onset up to 15 minutes in advance.
