Some results on the information loss in dynamical systems
BC Geiger, G Kubin - Wireless Communication Systems ( …, 2011 - ieeexplore.ieee.org Abstract In this work we investigate the information loss in (nonlinear) dynamical input- output systems and provide some general results. In particular, we present an upper bound on the information loss rate, defined as the (non-negative) difference between the entropy ...

On the Rate of Information Loss in Memoryless Systems
BC Geiger, G Kubin - arXiv preprint arXiv:1304.5075, 2013 - arxiv.org Abstract: In this work we present results about the rate of (relative) information loss induced by passing a real-valued, stationary stochastic process through a memoryless system. We show that for a special class of systems the information loss rate is closely related to the ...
“Cea mai dedicata, draguta si deschisa profa de mate. Miss Georgiana ne indeamna mereu sa fim productivi, sa gandim logic, rapid, dar si corect! Matematica e mult mai simpla dupa ce iti explica miss G.
P.S. Este experta in meme-uri si are mereu bomboane pe masa!
