摘要
En 中文
The most diffusion algorithms based on the mean square error (MSE) criterion generally have good per-formance in the presence of Gaussian noise, however suffer from performance deterioration under non -Gaussian noises. To combat non-Gaussian noises, a diffusion minimum kernel risk sensitive mean p -power loss (DMKRSP) algorithm is first designed using a generalized robust kernel risk sensitive mean p-power loss (KRSP) criterion combined with stochastic gradient descent (SGD). Then, due to more er-ror information than SGD, the adaptive gradient (Adagrad) is used in DMKRSP to generate a diffusion Adagrad minimum kernel risk sensitive mean p-power loss (DAMKRSP) algorithm. Finally, the theoreti-cal analysis of DMKRSP and DAMKRSP is presented for steady-state performance analysis. Simulations on system identification show that both DMKRSP and DAMKRSP are superior to other classical algorithms in term of robustness and filtering accuracy.(c) 2022 Elsevier B.V.
