Abstract : A new statistical approach using Gaussian processes is proposed to to classify irregularly sampled signals without temporal rescaling. Moreover, the model offers a theoretical framework to impute missing values. First experiments on simulated data show promising results both in terms of classification and imputation accuracy. Good robustness properties with respect to the modelling assumptions are also observed.
