Rate–distortion theory was created by Claude Shannon in his foundational work on information theory. In rate–distortion theory, the rate is usually understood as the number of bits per data sample to be stored or transmitted. The notion of distortion is a subject of on-going discussion. Visa mer Rate–distortion theory is a major branch of information theory which provides the theoretical foundations for lossy data compression; it addresses the problem of determining the minimal number of bits per symbol, as … Visa mer Distortion functions measure the cost of representing a symbol $${\displaystyle x}$$ by an approximated symbol $${\displaystyle {\hat {x}}}$$.
