Volterra models can be used to represent a nonlinear systems with vanishing memory. The main drawback of these models is their huge number of parameters to be estimated. To reduce this parametric complexity, we can consider Volterra kernels of order (p > 2) as symmetric tensors and we use a parallel factor (PARAFAC) decomposition of the kernels to derive Volterra-PARAFAC models. In this paper, we present partial update LMS algorithms for identifying nonlinear third-order Volterra-PARAFAC models… CONTINUE READING
