      On the effect of misspecifying the density ratio model 

      Fokianos, Konstantinos; Kaimi, I. (2006)
      The density ratio model specifies that the log-likelihood ratio of two unknown densities is of known linear form which depends on some finite dimensional parameters. The model can be broadened to allow for m-samples in a ...

      Position error signal estimation at high sampling rates using data and servo sector measurements 

      Ioannou, Petros A.; Kosmatopoulos, E. B.; Despain, A. M. (2002)
      Track density in hard disk drives (HDD) is related to the performance characteristics of the HDD servo control system. Higher track density can be achieved by improving the performance characteristics of the servo controller ...

      Random spectral measure for non Gaussian moving averages 

      Baxevani, Anastassia; Podgórski, K. (2017)
      We study the distribution of phases and amplitudes for the spectral representation of weighted moving averages of a general noise measure. The simple independent structure, known for the Gaussian case, and involving Rayleigh ...

      Variable target values neural network for dealing with extremely imbalanced datasets 

      Karatsiolis, Savvas; Schizas, Christos N. (Springer Verlag, 2016)
      An original classification algorithm is proposed for dealing with extremely imbalanced datasets that often appear in biomedical problems. Its originality comes from the way a neural network is trained in order to get a ...
