English abstract:
Abstract-In this contribution we provide a thorough stability analysis
of gradient type algorithms with non-symmetric matrix step-sizes. We
hereby extend existing analyses for symmetric matrix step-sizes and
present several methods to derive step-size bounds. Although we can
guarantee the l2−stability for such algorithms only under very restrictive
conditions, we are able to proof convergence in the mean square sense
under much more general conditions. Some of the derived step-size
bounds turn out to very tight and allow for accurate algorithmic design.
