    • Framework for online superimposed event detection by sequential Monte Carlo methods 

      Urfalıoğlu, Onay; Kuruoğlu, E. E.; Çetin, A. Enis (IEEE, 2008-03-04)
      In this paper, we consider online seperation and detection of superimposed events by applying particle filtering. We concentrate on a model where a background process, represented by a 1D-signal, is superimposed by an ...
    • Levy walk evolution for global optimization 

      Urfalıoğlu, Onay; Çetin, A. Enis; Kuruoğlu, E. E. (ACM, 2008-07)
      A novel evolutionary global optimization approach based on adaptive covariance estimation is proposed. The proposed method samples from a multivariate Levy Skew Alpha-Stable distribution with the estimated covariance matrix ...
    • Superimposed event detection by sequential Monte Carlo methods 

      Urfalıoğlu, O.; Kuruoğlu, E. E.; Çetin, A. Enis (IEEE, 2007)
      In this paper, we consider the detection of rare events by applying particle filtering. We model the rare event as an AR signal superposed on a background signal. The activation and deactivation times of the AR-signal are ...
