Что (кто) такое Rice coding - определение

LOSSLESS DATA COMPRESSION METHOD
Rice coding; Rice codes; Golomb code; Rice code; Golomb-Rice code; Golomb Rice code; Golomb-coded set
  •  1 − ''p''(0) ≥ 0.45}}
  • ''M'' {{=}} 3}}.  The 2-bit code 00 is used 20% of the time; the 3-bit codes 010, 011, and 100 are used over 38% of the time; 4 bits or more are needed in a minority of cases.  For this source, entropy = 3.610 bits; for this code with this source, rate = 3.639 bits; therefore redundancy = 0.030 bits, or efficiency = 0.992 bits per bit.

Golomb coding         
Golomb coding is a lossless data compression method using a family of data compression codes invented by Solomon W. Golomb in the 1960s.
Rice (surname)         
FAMILY NAME
Dr. Rice; Representative Rice
Rice is a surname that is frequently of Welsh origin, but also can be Irish, English, or even German. In Wales it is a patronymic surname, an Anglicized transliteration of Rhys, as are Reese and Reece.
Coding region         
  • '''Transcription''': RNA Polymerase (RNAP) uses a template DNA strand and begins coding at the promoter sequence (green) and ends at the terminator sequence (red) in order to encompass the entire coding region into the pre-mRNA (teal). The pre-mRNA is polymerised 5' to 3' and the template DNA read 3' to 5'
  • Karyotype}}
  • An electron-micrograph of DNA strands decorated by hundreds of RNAP molecules too small to be resolved. Each RNAP is transcribing an RNA strand, which can be seen branching off from the DNA. "Begin" indicates the 3' end of the DNA, where RNAP initiates transcription; "End" indicates the 5' end, where the longer RNA molecules are completely transcribed.
  • '''Point mutation types:''' transitions (blue) are elevated compared to transversions (red) in GC-rich coding regions.
PORTION OF A GENE'S DNA OR RNA, COMPOSED OF EXONS, THAT CODES FOR PROTEIN; COMPOSED OF CODONS, WHICH ARE DECODED, TRANSLATED INTO PROTEINS BY THE RIBOSOME; BEGINS WITH THE START CODON AND END WITH A STOP CODON
Coding sequence; Coding regions; Coding DNA sequence; Protein coding region; Protein coding sequence; Gene coding; Coding DNA; Protein-coding
The coding region of a gene, also known as the coding sequence (CDS), is the portion of a gene's DNA or RNA that codes for protein. Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene organization and evolution of prokaryotes and eukaryotes.

Golomb coding

Golomb coding is a lossless data compression method using a family of data compression codes invented by Solomon W. Golomb in the 1960s. Alphabets following a geometric distribution will have a Golomb code as an optimal prefix code, making Golomb coding highly suitable for situations in which the occurrence of small values in the input stream is significantly more likely than large values.
