| Abstract(in English) | In this paper we discuss the semiparametric statistical model for blind deconvolution. First the blind deconvolution problem is formulated in the framework of a semiparametric model, and a family of estimating functions is derived for blind deconvolution. To improve learning efficiency of online algorithm, an explicit form of the standardized estimating function is given. Superefficiency of off-line learning and online learning is proven in this framework. The theory of semiparametric models for blind deconvolution shows that both the batch learning and the natural gradient learning converge to the true solution if certain nonsingular conditions are satisfied, needless to estimate the nuisance parameters, the probalility density functions of source signals. |
