Eexda booska ALiBi
ALiBi (Fiiro gaar ah leh eexashada toosan) waa hab xariif ah oo lagu siiyo transformers dareenka habaynta erayga iyada oo aan meel dhaqameed lagu dhejin.
Dulmar
It lets a model trained on short text handle much longer inputs at inference time.
quusid qoto dheer
Transformers ma laha fikrad ku dhisan habaynta kelmad, marka waxay u baahan yihiin hab lagu codeeyo booska. Habka qadiimiga ah wuxuu ku darayaa meelaynta mawqifka calaamadeeyayaasha. ALiBi, oo ay soo bandhigeen Press, Smith, iyo Lewis sanadka 2021, ayaa gabi ahaanba meesha ka saaray. Taa baddalkeeda, waxay si toos ah u nuugaysaa dhibcaha dareenka: marka calaamada waydiinta ay eegto calaamada muhiimka ah, ALiBi waxay ka jartaa ciqaabta u dhiganta masaafada u dhaxaysa. Calaamadaha aad u kala fog waxay helayaan ciqaab weyn, markaa moodalku wuxuu si dabiici ah u doorbidaa macnaha guud ee u dhow. Madax kasta oo fiiro gaar ah leh wuxuu helayaa jiirada ciqaabta go'an, sidaa darteed madaxyada qaar waxay eegaan gudaha halka kuwa kalena ay wax ka sii arkaan. Sababtoo ah eexdu waa uun shaqo fogaansho, ALiBi waxay si xarrago leh u soo saartaa tixanayaal aad uga dheer kuwa lagu arkay tababarka.
Aragtida Farsamada
Weydiinta booska i iyo furaha booska j, ALiBi waxay ku darsataa m * (j - i) dhibcaha dareenka cayriin ka hor softmax, halkaas oo m ay tahay mid joogto ah oo madax-gaar ah (jiirarka waxay sameeyaan isku xigxiga joomatari sida 1/2, 1/4, 1/8). Maadaama j uu ka yar yahay ama la siman yahay i marka la eego dareenka sababta, ereygani waa eber ama taban, ciqaabaya calaamado fog. Ma jiro halbeegyo la bartay iyo wax ku dhejis ah oo laguma darin, markaa waxa kaliya ee ka sarreeya waa matrix eexda oo la sii xisaabiyay.

Xawaaraha iyo miisaanka
Socodka shaqada luqaddu si dhakhso leh ayay u socon kartaa iyada oo aan la hurayn joogteynta.

Waxay balaadhisaa gelitaanka luqadaha iyo qaababka isgaarsiinta.
Go'aamo cad
Kooxuhu waxay waqti badan ku qaadan karaan xukunka halka otomaatiggu uu qabanayo ku celcelinta.
Mustaqbalka Eexda Mawqifka ALiBi
ALiBi waxay cadaysay in qaraabada, eexda ku salaysan masaafada ay garaacday meelaynta saxda ah ee isku xidhka dhererka guud, iyo fikraddaasi hadda waxay dhex maraysaa naqshad casri ah oo casri ah. Qaar ka mid ah moodooyinka dhawaa waxay door bidaan isku-xidhka rotary-ga (RoPE), laakiin ALiBi ayaa weli caan ku ah halka ay khusayso ka-saarista xad-dhaafka ah waxaana loo adeegsaday moodooyinka sida BLOOM iyo MPT. Filo tijaabinta isku-dhafka ah ee sii socota, isku darka eexda fogaanta iyo cabirida RoPE, iyadoo shaybaaradu ay daaqadaha macnaha guud u riixayaan malaayiin calaamado ah iyada oo aan dib looga taborin xoq.

Su'aalaha soo noqnoqda
What is ALiBi Position Bias?
ALiBi (Fiiro gaar ah leh eexasho toosan) waa hab xariif ah oo lagu siiyo transformers dareenka habaynta erayga iyada oo aan meel dhaqameed lagu dhejin. Waxa ay u ogolaataa qaabka lagu tabobaran qoraalka gaaban in uu qabto wax qabad aad u dheer marka la eego.
Maxay u taagan tahay ALiBi?
ALiBi waxay u soo gaabisay Feejignaan leh eexasho toosan, oo loogu magac daray ciqaabta tooska ah ee ay ku kordhiso dhibcaha dareenka.
Sidee buu ALiBi u ciqaabaa calaamadaha fog?
ALiBi waxay ka jartaa qiimaha u dhigma fogaanta weydiinta-furaha dhibcaha dareenka, sidaas darteed calaamaduhu waxay helayaan miisaan yar.
Waa maxay faa'iidada wax ku oolka ah ee aadka loo dabaaldego ee ALiBi?
Sababtoo ah eexdu waxay ku xiran tahay masaafada oo kaliya, moodooyinka lagu tababaray taxanaha gaaban waxay xamili karaan kuwa aad u dheer wakhtiga fikradda.
Maxaa ka duwan eexda toosan ee madaxa dareenka?
ALiBi waxay u qoondaysaa madax kasta meel gaar ah oo leexsan (tusaale, 1/2, 1/4, 1/8), sidaa darteed madax kala duwan ayaa ka qayb gala noocyo kala duwan.
Marka la barbar dhigo meelaynta soojireenka ah, ALiBi waxay ku darsataa inta cabbir ee la bartay?
ALiBi ma soo bandhigto cabbiro cusub oo la bartay; jiirarka madax kasta waa joogto la sii go'aamiyay.
