He demonstrated indeed that the information generated by a source depends only on its statistics and not on the meaning of the source output. In this talk we consider the systems where codewords do have meaning, i.e. where codewords are semantic and close to the original source sequences. In this talk we define the notions of semantic compaction, transmission and compression. We state some fundamental limits, and sketch proof strategies. As a corollary, we state a fundamental limit on correlated watermarking. This is joint work with Frans Willems.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shannon wrote in 1948: &#8220;The semantic aspects of communication are irrelevant to the engineering problem&#8221;.
