Error Propagation in Adaptation Algorithms with Poorly Exciting Signals

Abstract [en]

The propagation of single numerical errors is studied for several different adaptation algorithms for linear regression problems. The case where the regressors are poorly exciting (the information matrix is singular or close to singular) is of particular interest. It is shown how appropriate regularization algorithms may secure exponential stability of the error propagation (and of the propagation of initial conditions in general). Gradient and Gauss-Newton algorithms with forgetting factors as well as directional forgetting are studied.
