here is your answer hope it helps ☺️
Step-by-step explanation:
Asymmetric numeral systems (ANS)[1] is a family of entropy encoding methods introduced by Jarosław (Jarek) Duda[2] from Jagiellonian University, used in data compression since 2014[3] due to improved performance compared to previously used methods, being up to 30 times faster.[4] ANS combines the compression ratio of arithmetic coding (which uses a nearly accurate probability distribution), with a processing cost similar to that of Huffman coding. In the tabled ANS (tANS) variant, this is achieved by constructing a finite-state machine to operate on a large alphabet without using multiplication.
Among others, ANS is used in the Facebook Zstandard compressor[5][6] (also used e.g. in Linux kernel,[7] Android[8] operating system, was published as RFC 8478 for MIME[9] and HTTP[10]), in the Apple LZFSE compressor,[11] Google Draco 3D compressor[12](used e.g. in Pixar Universal Scene Description format[13]) and PIK image compressor,[14] in CRAM DNA compressor[15] from SAMtools utilities, Dropbox DivANS compressor,[16] and in JPEG XL[17] next generation image compression standard.
The basic idea is to encode information into a single natural number {\displaystyle x}x. In the standard binary number system, we can add a bit {\displaystyle s\in \{0,1\}}{\displaystyle s\in \{0,1\}} of information to {\displaystyle x}x by appending {\displaystyle s}s at the end of {\displaystyle x}x which gives us {\displaystyle x'=2x+s}{\displaystyle x'=2x+s}. For an entropy coder, this is optimal if {\displaystyle \Pr(0)=\Pr(1)=1/2}{\displaystyle \Pr(0)=\Pr(1)=1/2}. ANS generalizes this process for arbitrary sets of symbols {\displaystyle s\in S}s\in S with an accompanying probability distribution {\displaystyle (p_{s})_{s\in S}}{\displaystyle (p_{s})_{s\in S}}. In ANS, if {\displaystyle x'}x' is the result of appending the information from {\displaystyle s}s to {\displaystyle x}x, then {\displaystyle x'\approx x\cdot p_{s}^{-1}}{\displaystyle x'\approx x\cdot p_{s}^{-1}}. Equivalently, {\displaystyle \log _{2}(x')\approx \log _{2}(x)+\log _{2}(1/p_{s})}{\displaystyle \log _{2}(x')\approx \log _{2}(x)+\log _{2}(1/p_{s})}, where {\displaystyle \log _{2}(x)}\log _{2}(x) is the number of bits of information stored in the number {\displaystyle x}x and {\displaystyle \log _{2}(1/p_{s})}{\displaystyle \log _{2}(1/p_{s})} is the number of bits contained in the symbol {\displaystyle s}s.
For the encoding rule, the set of natural numbers is split into disjoint subsets corresponding to different symbols – like into even and odd numbers, but with densities corresponding to the probability distribution of the symbols to encode. Then to add information from symbol {\displaystyle s}s into the information already stored in the current number {\displaystyle x}x, we go to number {\displaystyle x'=C(x,s)\approx x/p}{\displaystyle x'=C(x,s)\approx x/p} being the position of the {\displaystyle x}x-th appearance from the {\displaystyle s}s-th subset.
There are alternative ways to apply it in practice – direct mathematical formulas for encoding and decoding steps (uABS and rANS variants), or one can put the entire behavior into a table (tANS variant). Renormalization is used to prevent {\displaystyle x}x going to infinity – transferring accumulated bits to or from the bitstream
Answer:
mark as brainlist and follow me
Step-by-step explanation:
lack or absence of symmetry: as. a : lack of proportion between the parts of a thing especially : want of bilateral symmetry asymmetry in the development of the two sides of the brain. b : lack of coordination of two parts acting in connection with one another asymmetry of convergence of the eyes.
