%0 Journal Article %T A new structure exploiting derivation of recursive direct weight optimization %A Liang Dai %A Thomas B. Sch£¿n %J Computer Science %D 2014 %I arXiv %X The recursive direct weight optimization method is used to solve challenging nonlinear system identification problems. This note provides a new derivation and a new interpretation of the method. The key underlying the note is to acknowledge and exploit a certain structure inherent in the problem. %U http://arxiv.org/abs/1411.4018v1
