In the field of data compression, Shannon coding, named after its creator, Claude Shannon, is a lossless data compression technique for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured).
A few years later, David A. Huffman (1952) [13] gave a different algorithm that always produces an optimal tree for any given symbol probabilities. While Fano's Shannon–Fano tree is created by dividing from the root to the leaves, the Huffman algorithm works in the opposite direction, merging from the leaves to the root.
Shannon–Fano–Elias coding produces a binary prefix code, allowing for direct decoding.. Let bcode(x) be the rational number formed by adding a decimal point before a binary code.
Herbert Brown Huffman (1905–1968) was a prominent American choral director during the mid 20th century who founded the Columbus Boychoir School, now the American Boychoir School. [1] For over 75 years, this internationally acclaimed choral group has performed in venues across the United States and in overseas locations.
They notified friends and relatives, wrote a eulogy for their newspaper, and made funeral arrangements. They held the memorial service on what would have been their son’s 26th birthday. At Recovery Works, Patrick’s former treatment facility, his name and photo were added to a memory wall in a common room — another fatal overdose in a ...
A Massachusetts teacher and her 1-year-old baby have died after they were trapped in a New York house fire, according to authorities. Crews responded to the scene on Clinton Hollow Road in Clinton ...

In information theory, an entropy coding (or entropy encoding) is any lossless data compression method that attempts to approach the lower bound declared by Shannon's source coding theorem, which states that any lossless data compression method must have an expected code length greater than or equal to the entropy of the source.
