kritrim tantrika tantra kaa ganit

ack kritrim tantrika tantra (aine) pattern pehchaan aur khel-khel jaise kshetron mein samasyaon koo hull karane key liye unnat aankadon key saath javic siddhanton koo jodata haye. aine vibhinn tarikon seey ack dusare seey judey neuron analogue key buniyaadi model koo apanaate hain.
sanrachana.
neuron.
poorvavarti neurons seey ack input sootra _ 2 praapt karane vaale label sootra _ 1 key saath ack neuron mein nimnalikhit ghatak hotey hainh
aksar output function kewal pehchaan function hotaa haye.
ack "input neuron" kaa koee poorvavarti naheen hotaa haye lekin yeh poore network key liye input interfaces key roop mein kaary kartaa haye. isi tarah ack "output neuron" kaa koee uttaradhikari naheen hotaa haye aur iss prakaar yeh poore network key output interfaces key roop mein kaary kartaa haye.
prasaar kaary.
prasaar kaary" output sootra _ 15 seey neuron sootra _ 1 key liye "input" sootra _ 2 kii ganana kartaa haye aur aamtaur parr iska roop hotaa haye.
pakshapaat.
ack pakshapaat shabd jodaa jaa sakata haye, roop koo nimnalikhit mein badala jaa sakata haih
tantrika network kaary key roop mein.
tantrika tantra model koo ack aise kaary koo paribhaashit karane key roop mein dekhaa jaa sakata haye joe ack input (avalokan) letaa haye aur ack output (nirnay) sootra _ 19 yaa sootra _ 20 yaa donon sootra _ 20 aur sootra _ 22 parr vitaran kaa utpaadan kartaa haye. kabhi-kabhi model ack vishesh seekhane key niyam key saath ghanishth roop seey judey hotey hain. aine model" vakyansh kaa ack samanya upayog vaastav mein aise karyon key "varg" kii paribhasha haye (jahaan varg key sadasyon koo vibhinn maapdandon, connection bhaar, yaa vastukala key vishishtataon jaise neurons kii sankhya, paraton kii sankhya yaa unaki connectivity dwara praapt kiya jaataa haye).
ganitiya roop seey, ack neuron key network function sootra _ 23 koo anya karyon key sootra _ 24 kii sanrachana key roop mein paribhaashit kiya gayaa haye, jise aage anya karyon mein vighatit kiya jaa sakata haye. ise ack network sanrachana key roop mein suvidhajanak roop seey darshaaya jaa sakata haye, jisamen karyon key beach nirbharta koo darshaane vaale teer hain. ack vyaapak roop seey upayog kii jaane vaali sanrachana "araikhik bhaarit yog" haye, jahan sootra _ 25, jahan sootra _ 26 (aamtaur parr sakriyan kaary key roop mein sandarbhit) kuchh purvanirdhaarit kaary haye, jaise kii hyperbolic sparshrekha, sigmoid kaary, softmax kaary, yaa rectifier kaary. sakriyan kaary kii mahatvapurna visheshta yeh haye kii yeh input moolyon key parivartan key roop mein ack sucharu sankraman pradaan kartaa haye.ee. input mein ack chhota saa parivartan output mein ack chhota saa parivartan paida kartaa haye. nimnalikhit ack sadish sootra key roop mein falan sootra _ 27 key sangrah koo sandarbhit kartaa haye.
yeh aakriti sootra _ 29 key aise apghatan koo darshaati haye, jisamen teeron dwara ingit charon key beach nirbharta hoti haye. inki vyakhya dou tarikon seey kii jaa sakati haye.
pahala drishya karyatmak drishya haih input sootra _ 30 koo ack 3-ayami sadish sootra _ 31 mein parivartit curr diyaa jaataa haye, jise phir ack 2-ayami sadish sootra _ 32 mein parivartit curr diyaa jaataa haye, jise anta mein sootra _ 29 mein parivartit curr diyaa jaataa haye. yeh drishya aamtaur parr anukoolan key sandarbh mein dekhaa jaataa haye.
doosara drishya sambhaavit drishtikon haih yaadrichhik charr sootra _ 34 yaadrichhik charr sootra _ 35 parr nirbhar kartaa haye, joe sootra _ 36 parr nirbhar kartaa haye, joe yaadrichhik charr sootra _ 20 parr nirbhar kartaa haye. yeh drishya aamtaur parr graphical model key sandarbh mein dekhaa jaataa haye.
donon vichaar kaafee hudd taka samaan hain. donon hii mamalon mein, iss vishesh vastukala key liye, alag-alag paraton key ghatak ack-dusare seey swatantra hain (ee.jee.sootra _ 32 key ghatak apane input sootra _ 31 koo dekhate hue ack dusare seey swatantra hain. yeh swabhavik roop seey karyanvayan mein ack degree samanantarta koo saksham banaata haye.
pichhale jaise network koo aamtaur parr feedforward kahaa jaataa haye, kyonki unakaa graph ack nirdeshit chakreeya graph haye. chakron vaale network koo aamtaur parr aavarti kahaa jaataa haye. aise network koo aamtaur parr aakriti key sheersh parr dikhaae gaye tareeke seey darshaaya jaataa haye, jahaan sootra _ 29 koo khud parr nirbhar key roop mein dikhaaya jaataa haye. haalaanki, ack nihit laukik nirbharta naheen dikhaai gaee haye.
backpropagation.
backpropagation prashikshan algorithm teen shreniyon mein aatey hainh
algorithm.
sootra _ 41 koo sootra _ 42 connection, sootra _ 43 input aur sootra _ 44 output key saath ack network honey dein.
neeche, sootra _ 45 sootra _ 46 mein vactor koo darshaata haye, sootra _ 48 mein sootra _ 47 vactor, aur sootra _ 50 mein sootra _ 49 vactor. inhen kramshah "input", "output" aur "wait" kahaa jaataa haye.
network ack function sootra _ 51 seey mell khaata haye, joe ack vajan sootra _ 52 diye jaane parr, ack input sootra _ 53 koo ack output sootra _ 54 key liye mapp kartaa haye.
paryavekshit shikshan mein, "prashikshan udaaharan" sootra kaa ack crum _ 55 kuchh praarambhik vajan sootra _ 57 seey shuru hocker vajan sootra _ 56 kaa ack anukram utpann kartaa haye, jise aamtaur parr yaadrichhik roop seey chunaa jaataa haye.
inn bhaaron kii ganana baari-baari seey kii jaati haih pahale sootra _ 60 key liye kewal sootra _ 59 kaa upayog karke sootra _ 58 kii ganana karein. algorithm kaa output phir sootra _ 61 haye, joe ack nayaa kaary sootra _ 62 detaa haye. ganana pratyek charan mein samaan haye, isaliye kewal mamle key sootra _ 63 kaa varnan kiya gayaa haye.
sootra _ 64 kii ganana sootra _ 65 seey ack charr vajan sootra _ 52 parr vichaar karke aur sootra _ 68 seey shuru hocker sthaaniya nyuntam khojane key liye falan sootra _ 67 parr pravanata avrohan lagu karke kii jaati haye.
yeh sootra _ 64 koo dhaal avrohan dwara paaya jaane vaalaa nyuntam vajan banaata haye.
chhadm code seekhana.
uparokt algorithm koo lagu karane key liye, falan sootra _ 70 key pravanata key liye spasht sootra aavashyak hain jahan falan sootra _ 71 haye.
seekhane key algorithm koo dou charanon mein vibhajit kiya jaa sakata haih prasaar aur vajan adyatan.
prachaar.
prachaar mein nimnalikhit charan shamil hainh
vajan adyatan karein.
pratyek vajan key liyeh
seekhane kii darr" vaha anupaat (pratishat) haye joe seekhane kii gati aur gunavatta koo prabhaavit kartaa haye. anupaat jitna adhik hoga, neuron utani hii teji seey train karega, lekin anupaat jitna cumm hoga, prashikshan utanaa hii sateek hoga. vajan key dhaal kaa sanket ingit kartaa haye kii kyaa truti seedhe vajan key saath yaa vipareet roop seey bhinn hoti haye. isaliye, vajan koo vipareet disha mein, "avrohi" dhaal mein adyatan kiya jaanaa chaahiye.
jaba taka network paryaapt pradarshan naheen kartaa, taba taka seekhane koo dohraya jaataa haye (nae baichon parr).
chhadm code.
teen-parat network (ack chhipi hui parat) key prashikshan key liye ack yaadrichhik dhaal avrohan algorithm key liye chhadm kodah
 network bhaar koo aarambh karein (aksar chhote yaadrichhik maan)

 jaba taka truti darr sweekarya roop seey cumm naheen hoe jaati haye
 network koo vaapas karein
backward paas" label vaali rekhaaon koo backpropagation algorithm kaa upayog karke lagu kiya jaa sakata haye, joe network key sanshodhit bhaar key sambandh mein network kii truti key pravanata kii ganana kartaa haye.
