New lower bounds for the Shannon capacity of odd cycles
Webbn. In information theory, a mathematical measure of the degree of randomness in a set of data, with greater randomness implying higher entropy and greater predictability implying lower entropy. Also called Shannon entropy. American Heritage® Dictionary of the English Language, Fifth Edition. WebbA special case of the lower bound for Euclidean norm is given by P D D SLB = h (θ) − sup h (W ) = h (θ) − h N 0, IP = h (θ) − log 2πe , P 2 P EkW k2 ≤D 2 where we used the fact that Gaussian maximizes differential entropy when the second moment is bounded. Theorem 13.1 (Shannon’s Lower Bound). Let k · k be an arbitrary norm on Rp and r > 0. orchid.org login

Webb17 dec. 2010 · The expression of the optimal causal data compression is derived. Further a tight lower bound on the rate distortion bound is derived. These are variants of the classical non-causal rate distortion function, and associate Shannon lower bound. Generalization of the results to controlled sources is also discussed. WebbShannon gave a lower bound in 1959 on the binary rate of spherical codes of given minimum Euclidean distance $\rho$. Using nonconstructive codes over a finite alphabet, we give a lower bound that is weaker but very close for small values of $\rho$. WebbAsymptotic Tightness of the Shannon Lower Bound Tobias Koch Universidad Carlos III de Madrid, Spain & Gregorio Marañón Health Research Institute Email: [email protected] Abstract The Shannon lower bound is one of the few lower bounds on the rate-distortion function that holds for a large class of sources.
