Abstract
The estimation of the intensity function of a Poisson-driven shot-nois e process is addressed using a regularization technique, where the dat a is modeled as a signal term plus a signal-dependent noise term. A ne w data-based method for selecting a pair of regularization parameters is presented and compared with the minimum unbiased risk method. The d etail in the intensity function can be recovered by both methods, but the new method does a better job at suppressing spurious oscillations.
