[581, 582], Hansen and O’Leary, and many other researchers[581, ... (2.97) and ∆H and ∆x refer to perturbations of the matrix H and sensor vector x, respectively.By changing the parameter γ in the range [0, 1], we obtain the special cases: the standardLS, TLS and ... computation of the parameterss for the system model. Adaptive algorithms that employ the TLS formulation and theirextensions have been developed and analyzed by Amari and Kawanabe, Mathews, Cichocki,Unbehauen,...
