vector matrankan

vector quantisation (vee. kyu.) sanket prasanskaran seey ack shaastriya quantisation takneek haye joe prototype vactors key vitaran dwara praayiktaa ghanatva karyon key modeling kii anumati detee haye. iska upayog mool roop seey detta sampeedan key liye kiya jaataa thaa. yeh binduon (vactor) key ack badey samooh koo samoohon mein vibhajit karke kaam kartaa haye, jinamen unake karib lagbhag samaan sankhya mein bindu hotey hain. pratyek samooh koo usake kendra bindu dwara darshaaya jaataa haye, jaisa kii key-mean aur kuchh anya clustering algorithm mein hotaa haye.
vector matrankan kaa ghanatva milan guna shaktishali haye, vishesh roop seey badey aur uchch-ayami detta key ghanatva kii pehchaan karane key liye. choonki detta bindu unake nikatatam kendrak key soochkaank dwara darshaae jaate hain, aamtaur parr honey vaale detta mein cumm truti hoti haye, aur durlabh detta uchch truti hoti haye. yahee kaaran haye kii vee. kyu. haani detta sampeedan key liye upayukt haye. iska upayog haani detta sudhaar aur ghanatva anuman key liye bhee kiya jaa sakata haye.
vector quantisation pratispardhi seekhane key pratimaan parr adharit haye, isaliye yeh swa-vyavasthit maanchitra model aur autoencoder jaise gahan shikshan algorithm mein upayog kiye jaane vaale viral coding model seey nikatata seey sambandhit haye.
prashikshan.
vector matrankan key liye sabse saral prashikshan algorithm haih
ack adhik parishkrit algorithm ghanatva milan anuman mein purvagrah koo cumm kartaa haye, aur yeh sunishchit kartaa haye kii ack atirikt samvedansheelta parameter koo shamil karke sabhi binduon kaa upayog kiya jaataa haih
abhisaran utpann karane key liye ack sheetlan anusuchi kaa upayog karna vaanchhaniya haih nakali aniling dekhein. ack anya (saral) vidhi ell. bee. jee. haye joe key-means parr adharit haye.
algorithm koo detta sett seey yaadrichhik binduon koo chunane key bajaay 'live' detta key saath punaravritti seey update kiya jaa sakata haye, lekin yeh kuchh purvagrah pesh karega yadi detta kaee namoonon parr asthaayi roop seey sahsambaddh haye.
aavedan.
vector quantisation kaa upayog haani detta sampeedan, haani detta sudhaar, pattern pehchaan, ghanatva anuman aur cluster key liye kiya jaataa haye.
haani detta sudhaar, yaa bhavishyavani, kaa upayog kuchh aayamon seey gayab detta koo punarpraapt karane key liye kiya jaataa haye. yeh upalabdh detta aayamon key saath nikatatam samooh koo dhundhkar kiya jaataa haye, phir laapata aayamon key moolyon key aadhar parr parinam kii bhavishyavani karate hue, yeh maanate hue kii unakaa moolya samooh key kendrak key samaan hoga.
ghanatva anuman key liye, kshetra/aayatan joe kissy anya kii tulanaa mein kissy vishesh kendrak key karib haye, ghanatva key vyutkramaanupaati haye (algorithm key ghanatva milan guna key kaaran).
detta sampeedan mein upayog karein.
vector quantisation, jise "block quantisation" yaa "pattern matching quantisation" bhee kahaa jaataa haye, kaa upayog aksar lossy detta sampeedan mein kiya jaataa haye. yeh ack bahuayami sadish sthaan seey moolyon koo nimn ayam key ack asatat upasthaan seey moolyon key ack seemit samooh mein kootbaddh karke kaam kartaa haye. ack nimn-sthaan sadish koo cumm bhandaran sthaan kii aavashyakta hoti haye, isaliye detta koo sampeedit kiya jaataa haye. vector quantisation key ghanatva milan guna key kaaran, sampeedit detta mein trutiyaan hoti hain joe ghanatva key vyutkram anupaat mein hoti hain.
parivartan aamtaur parr prakshepan yaa codebook kaa upayog karke kiya jaataa haye. kuchh mamalon mein, ack codebook kaa upayog usee charan mein asatat moolya koo kootbaddh karane key liye bhee kiya jaa sakata haye, isake output key roop mein ack upsarg kodit charr-lambai kootbaddh moolya utpann karke.
pratyek namoone koo alag seey matratmak banaane key bajaay asatat ayam staron key samooh koo sanyukt roop seey matratmak kiya jaataa haye. ayam staron key "key"-ayami sadish sootra _ 12 parr vichaar karein. ise "n"-ayami sadish sootra _ 13 key ack samooh seey nikatatam milan sadish kaa chayan karke "n" <"k" key saath sampeedit kiya jaataa haye.
aine"-ayami sadish sootra key sabhi sambhaavit sanyojan sadish sthaan banaate hain jisamen sabhi matratmak sadish sambandhit hotey hain.
matratmak moolyon key bajaay codebook mein kewal codeward kaa soochkaank bheja jaataa haye. yeh sthaan kii bachat kartaa haye aur adhik sampeedan praapt kartaa haye.
twin vector quantisation (vee. kyu. aff.) aim. pee. ee. jee.-4 maanak kaa hissa haye joe samay kshetra bhaarit interleaved vector quantisation seey sambandhit haye.
vector matrankan parr adharit video codec.
vector quantisation parr adharit video codec kaa upayog parivartan coding key saath sanyukt gati pratipoorit bhavishyavani key aadhar parr unake paksh mein kaafee cumm hoe gayaa haye.jee. vector quantisation kii cumm decoding jatilata key roop mein jinhen aim. pee. ee. jee. manakon mein paribhaashit kiya gayaa haye, way cumm praasangik hoe gaye hain.
pattern pehchaan mein upayog karein.
vee. kyu. kaa upayog assie key dashak mein bhaashan aur vaktaa kii pehchaan key liye bhee kiya jaataa thaa.
haal hii mein iska upayog kushal nikatatam padosi khoj key liye bhee kiya gayaa haye. 
aur online hastakshar maanyata. 
pattern pehchaan anuprayogon mein, iss upayogkarta key dhwanik vactor kaa upayog karke pratyek varg key liye ack codebook kaa nirmaan kiya jaataa haye (pratyek varg biometric anuprayogon mein ack upayogkarta honey key kaaran). pareekshan charan mein ack pareekshan sanket key matratmak vikriti koo prashikshan charan mein praapt codebook key poore sett key saath kaam kiya jaataa haye. codebook joe sabse chhoti vector matratmak vikriti pradaan karati haye, pehchaane gaye upayogkarta koo ingit karati haye.
pattern pehchaan mein vee. kyu. kaa mukhya laabh iska cumm computational bojh haye jaba anya takneekon jaise kii dynamic time warping (dee. tii. doubleu.) aur hiddon markov model (aich. aim. aim.) kii tulanaa mein. dee. tii. doubleu. aur aich. aim. aim. kii tulanaa mein mukhya kamee yeh haye kii yeh sanketon (bhaashan, hastakshar, aadi) key asthaayi vikas koo dhyaan mein naheen rakhta haye.) kyonki sabhi vactor mishrit hain. iss samasya koo door karane key liye ack bahu-anubhaag codebook drishtikon prastaavit kiya gayaa haye. bahu-anubhaag drishtikon mein kaee anubhagon key saath sanket kaa pratiroopan shamil haye (udaaharan key liye, praarambhik bhaag key liye ack codebook, kendra key liye doosari aur antim bhaag key liye ack antim codebook).
clustering algorithm key roop mein upayog karein.
choonki vq paas key lette hue namoonon key ghanatva binduon key roop mein centroid kii talash curr rhaa haye, isaliye iska upayog seedhe prototype-adharit clustering vidhi key roop mein bhee kiya jaa sakata haih pratyek centroid koo phir ack prototype key saath jodaa jaataa haye. 
apekshit varg parimanikaran truti koo cumm karane key uddeshya seey aur robbin-monro sthitiyon koo puuraa karane vaale ghatate seekhane key laabh koo pesh karke, prototype kii ack thhos lekin nishchit sankhya key saath poore detta sett parr kaee punraavrittiyaan key-mean clustering algorithm key samadhan mein parivartit hoe jaati hain.
utpaadak pratikool network (jee. aeye. aine.).
vq kaa upayog utpaadak pratikool network key bhedbhaav mein ack visheshta pratinidhitva parat kii matra nirdhaarit karane key liye kiya gayaa haye. visheshta matrankan (aff. kyu.) takneek antarnihit visheshta milan karati haye. yeh gunn prashikshan mein sudhaar kartaa haye, aur vibhinn prakaar key lokpriya gunn model parr behtar pradarshan detaa haih chhavi nirmaan key liye biggun, chehare key sanshleshan key liye stylegan, aur binaa nigrani vaali chhavi-seey-chhavi anuvaad key liye yuu-gatt-itt.
yeh bhee dekhein.
"iss lekh kaa ack hissa mool roop seey computing key muft online shabdakosh kii samagri parr adharit thaa aur iska upayog jee. aff. dee. ell. key tahat kiya jaataa haye."
