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 $${\displaystyle {\hat {x}}}$$.
