Semantic Compression with Information Lattice Learning
Keywords: semantic communication, information lattice learning, data compression, foundation model, successive refinement, group codes
Abstract: Data-driven artificial intelligence (AI) techniques are becoming prominent for learning in support of data compression, but are focused on standard problems such as text compression. To instead address the emerging problem of semantic compression, we argue that the lattice theory of information is particularly expressive and mathematically precise in capturing notions of abstraction as a form of lossy semantic compression. As such, we demonstrate that a novel AI technique called information lattice learning, originally developed for knowledge discovery and creativity, is powerful for learning to compress in a semantically-meaningful way. The lattice structure further implies the optimality of group codes and the successive refinement property for progressive transmission.
