TY - JOUR ID - 379054 AU - Veselý, Vítězslav PY - 2001 TI - Kernel frame smoothing operators PB - JČMF Praha CY - Prague SN - 8070157925 KW - nctional approximation KW - kernel operators;frame and wavelet expansions KW - pseudoinverse operators N2 - Basics of frame expansions in separable Hilbert spaces are explained in context with the theory of pseudoinverse operators. A new geometric approach is outlined connecting both areas. An iterative frame-based procedure is suggested which finds, to a given function, a finite frame or Riesz basis for its expansion which is suboptimal in a certain sense. In particular a new type of kernel smoothing operator based on dual frame expansions is introduced with which the above procedure allows us to find easily not only suboptimal bandwidths (scales) as with common kernel smoothing, but also suboptimal shifts.
