Shannon rate distortion theory
WebbRate–distortion theory; Shannon's source coding theorem; Channel capacity; ... and is also referred to as Shannon entropy. Shannon's theory defines a data communication system composed of three elements: a source of data, a communication channel, and a receiver. 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 $${\displaystyle {\hat {x}}}$$. Typical distortion functions … Visa mer Suppose we want to transmit information about a source to the user with a distortion not exceeding D.
