The Lossy Common Information of Correlated Sources

On Common Information and Related Characteristics of Correlated Information Sources

Appendix: On Common Information and Related Characteristics of Correlated Information Sources

This is a literal copy of a manuscript from 1974. References have been updated. It contains a critical discussion of in those days recent concepts of “common information” and suggests also alternative definitions. (Compare pages 402–405 in the book by I. Csiszár, J. Körner “Information Theory: Coding Theorems for Discrete Memoryless Systems”, Akademiai Kiado, Budapest 1981.) One of our definiti...

Blind Separation of Jointly Stationary Correlated Sources

The separation of unobserved sources from mixed observed data is a fundamental signal processing problem. Most of the proposed techniques for solving this problem rely on independence or at least uncorrelation assumption for source signals. This paper introduces a technique for cases that source signals are correlated with each other. The method uses Wold decomposition principle for extracting ...

john steinbeck: friend of the american common man

in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...

Noiseless coding of correlated information sources

A new class of lower bounds to rate-distortion functions ofstationary processes with memory and single-letter vector-valued distor-tion measures is derived. This class is shown to include or imply all otherwell-known lower bounds to rates of such sources and distortion measures.The derivation is based on the definition and properties of the conditionalratedistortion function...
