Shabakadda Siamese iyo Khasaaraha Saddex-geesoodka ah
Shabakadaha Siamese waxay adeegsadaan laba ama in ka badan oo isku mid ah, laamo wadaaga miisaanka si ay u bartaan sida ay isku midka yihiin labada qalab, halkii ay kala saari lahaayeen mid kasta.

Triplet loss trains them by pulling matching items together and pushing mismatches apart, which is the backbone of face recognition, signature verification, and one-shot learning.
quusid qoto dheer
Shabakadda Siamese ayaa ku socodsiisa gelinta kasta iyada oo soo marinaysa codeer isku mid ah oo leh miisaan la wadaago, iyada oo soo saarta vector mid kasta. Halkii laga saadaalin lahaa calaamada fasalka, waxay is barbardhigtaa ku-xidhka iyadoo la isticmaalayo fogaan sida Euclidean ama cosine. Tani waxay u ogolaanaysaa nidaamku in uu aqoonsado qaybo cusub oo aanu waligiis tababbar ku qaadan - waa muhiim marka aad haysato hal ama dhawr tusaale oo aqoonsi ah (barashada hal xabbad ah). Noocyadii hore waxay isticmaaleen khasaare isbar-bardhig ah oo lammaane ah (la mid ah iyo mid aan la mid ahayn). Luminta saddex-geesoodka ah ayaa tan ku wanaajisay tababbarka seddexda wax-soo-saarka hal mar: barroosin, mid togan (isku mid ah barroosinka), iyo taban (fasalka kala duwan). Ujeedadu waxay ku qasbeysaa masaafada barroosinka-togan in ay ka yaraato masaafada barroosinka-negative marka loo eego margin, marka moodeelku waxa uu bartaa meel dhexda ah halkaas oo walxaha isku haybta ay si adag isugu urursan yihiin aqoonsiyo kala duwanina ay aad u kala fog yihiin.
Aragtida Farsamada
Khasaaraha saddex-geesoodka ah waa max (0, d (a,p) - d (a,n) + margin), halka d ay tahay masaafada, a/p/n waa barroosin/positive/negative, iyo margin waa farqiga go'an. Haddii xumaantu ay horeba u fogaatay, khasaaruhu waa eber oo waxba lama baran - markaa tayada tababbarku waxay ku xiran tahay macdanta adag ee taban: xulashada seddexleey halka taban ay si khiyaano leh ugu dhowdahay barroosinka. Miisaanka wadaagga laamaha oo dhan waxay dammaanad qaadayaan labadaba khariidadaha wax-soo-gelinta ee isku-xidhka meel bannaan, taas oo ah tan ka dhigaysa isbarbardhigga masaafada mid macno leh.

Mustaqbalka Shabakadda Siamese iyo Khasaaraha Saddex-geesoodka ah
Fikradda udub-dhexaadka ah - baro meel la isku dhejiyo halkaas oo masaafada ay la mid tahay isku ekaanshaha - hadda waxay wadaa barasho isbarbardhig ballaaran. Hababka sida SimCLR iyo moodooyinka sida CLIP waxay guudmariyaan mabda'a isku mid ah malaayiin sawirro iyo lammaane qoraal ah oo aan lahayn saddex-geesood oo cad. Filo barashada mitirka inay udub dhexaad u ahaato soo celinta, kala-saarista, talo bixinta, iyo raadinta xogta-vector-ka, halka khasaaraha cusub (InfoNCE, u ekaansho badan) iyo dufcaddo waaweyni ay si isa soo taraysa u beddelaan macdan-qodobeedka saddex-geesoodka ah ee waxtarka iyo miisaanka.

Luminta Saddex-geesoodka ah iyo Barashada Metric
Su'aalaha soo noqnoqda
What is Siamese Networks and Triplet Loss?
Shabakadaha Siamese waxay adeegsadaan laba ama in ka badan oo isku mid ah, laamo wadaaga miisaanka si ay u bartaan sida ay isku midka yihiin labada qalab, halkii ay kala saari lahaayeen mid kasta. Khasaare saddex-geesoodka ah ayaa ku tababara iyaga oo isku jiidaya walxaha isku midka ah oo kala riixaya is-maandhaafka, taas oo ah laf-dhabarta aqoonsiga wejiga, xaqiijinta saxeexa, iyo barashada hal-dar ah.
Waa maxay sifada qaab dhismeedka qeexan ee shabakada Siamese?
Laamaha isku midka ah ee miisaanka la wadaaga waxay hubisaa in dhammaan agabka la soo geliyay lagu habeeyey meel isku mid ah oo la isku dhejiyo si masaafada loo barbardhigo.
Khasaaraha saddex-geesoodka ah, waa maxay saddexda qalab?
Luminta saddex-geesoodka ah waxay isticmaashaa barroosin, togan (isku fasal) iyo taban (class kala duwan) si ay u qaabeeyaan booska dhexda.
Waa maxay ujeeddada luminta saddex-geesoodka ah ayaa dhaqangelisa?
Khasaaruhu waxa uu dhanka togan uga soo dhawaadaa kan taban ugu yaraan margin, isaga oo isku ururinaya walxo isku fasal ah.
Waa maxay sababta 'macdanta xun-xun' ay muhiim ugu tahay tababarka luminta saddex-geesoodka ah?
Haddii xumaantu hore u fog tahay, khasaaruhu waa eber; doorashada xumaanta u dhow si khiyaano leh waxay siinaysaa tusaalaha wax macno leh oo la barto.
Awood noocee ah ayaa ka dhigaysa shabakadaha Siamese qiimo 'waxbarasho hal-dhar ah'?
Sababtoo ah waxay bartaan isku ekaanshaha halkii ay ka baran lahaayeen calaamado go'an, waxay aqoonsan karaan aqoonsi-cusub hal tusaale oo diiwaangashan.
