Huffman coding
- 解説
- An entropy encoding method for lossless data compression. It uses a variable length code table for encoding a source symbol (such as a character in a file) where the variable-length code table has been derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol.

Huffman coding
語源
Named after its inventor David A. Huffman (1925–1999).
名詞
Huffman coding (countable かつ uncountable, 複数形 Huffman codings)
- (computing theory) An entropy-encoding algorithm used for lossless data compression, involving a variable-length code table derived from the estimated probability of occurrence of each symbol (so that more frequent symbols take less space to store).
- 2018, Keshab K. Parhi; Takao Nishitami, editors, Digital Signal Processing for Multimedia Systems[1], CRC Press, →ISBN:
- In Huffman coding, shorter code-words are assigned to more frequent symbols so that the average code-length is reduced.

In computer science and information theory, Huffman coding is an entropy encoding algorithm used for lossless data compression. The term refers to the use of a variable-length code table for encoding a source symbol (such as a character in a file) where the variable-length code table has been derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol. It was developed by David A. Huffman while he was a Ph.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
