      On Bayesian testimation and its application to wavelet thresholding 

      Abramovich, F.; Grinshtein, V.; Petsa, A.; Sapatinas, Theofanis (2010)
      We consider the problem of estimating the unknown response function in the Gaussian white noise model. We first utilize the recently developed Bayesian maximum a posteriori testimation procedure of Abramovich et al. (2007) ...

      On the estimation of the function and its derivatives in nonparametric regression: A bayesian testimation approach 

      Petsa, A.; Sapatinas, Theofanis (2011)
      We consider the problem of estimating the unknown response function and its deriva- tives in the standard nonparametric regression model. Recently, Abramovich et al. (2010) applied a Bayesian testimation procedure in a ...

      A switching adaptive controller for feedback linearizable systems 

      Kosmatopoulos, E. B.; Ioannou, Petros A. (1999)
      One of the main open problems in the area of adaptive control of linear-in-the-parameters feedback linearizable systems is the computation of the feedback control law when the identification model becomes uncontrollable. ...

      Wavelet thresholding via a Bayesian approach 

      Abramovich, F.; Sapatinas, Theofanis; Silverman, B. W. (1998)
      We discuss a Bayesian formalism which gives rise to a type of wavelet threshold estimation in nonparametric regression. A prior distribution is imposed on the wavelet coefficients of the unknown response function, designed ...
