Uhlolojikelele
I-Test-time augmentation (TTA) isebenzisa imodeli eqeqeshiwe ezinguqulweni ezimbalwa eziguquliwe zokokufaka okufanayo kanye nezilinganiso zokuqagela. Iqhinga elilula, elingenalo ukuqeqeshwa elivame ukuminyanisa amaphuzu ambalwa engeziwe okunemba futhi lenze izibikezelo zibe namandla kakhulu.
I-Test-Time Augmentation iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Ukwengeza isikhathi sokuhlola kuthatha okokufaka okukodwa, kudala amakhophi aguquliwe amaningi (okuphendukayo, izitshalo, ukuzungezisa, ukushintsha kombala, noma izinguqulo ezinezikali), kuqhuba ngakunye ngemodeli egxilile efanayo, bese kuhlanganisa okuphumayo - ngokuvamile ngamathuba amaphakathi noma amalogi. Umbono: i-augmentation ngayinye iveza imodeli ekubukeni okuhlukile, futhi amaphutha ekubukeni ngakunye avame ukukhansela lapho kuhlanganiswe, njengeqoqo elincane elakhiwe kusuka kunethiwekhi eyodwa. Okubaluleke kakhulu, i-TTA ayidingi ukuqeqeshwa kabusha futhi awekho amalebula engeziwe; kubiza kuphela ukubala okwengeziwe ekucabangeni ngoba imodeli isebenzisa izikhathi ezingu-N ngesampula ngayinye. Idume kakhulu embonweni wekhompyutha (ikakhulukazi imiqhudelwano ye-Kaggle kanye nesithombe sezokwelapha) kodwa futhi ivela kumsindo nombhalo. Ukwengeza kufanele kugcine ilebula — ukuphenyisisa i-X-ray yesifuba kulungile, kodwa ukuphenyisisa idijithi ethi '6' ibe '9' akunjalo.
I-Technical Insight
Uma amaphutha okubikezela kwemodeli kukho konke ukubuka okuthuthukisiwe engahlotshaniswa ngokwengxenye, isilinganiso sinciphisa ukuhluka okufana neqoqo - kodwa kusetshenziswa isethi eyodwa yesisindo. Ukuze uhlukanise ngokuvamile ulinganisela amathuba e-softmax (noma amalogi) phezu kokubukwa; ekuhlukaniseni kufanele uguqule uguquko ngalunye lwejiyomethri ngaphambi kokuhlanganisa ukuze amamephu we-pixel ahleleke kabusha. Ukukhetha izandiso zokulondoloza ilebula kubalulekile: uguquko olushintsha isigaba sangempela lufaka ukuchema kunokukhansela umsindo.
I-Mastering Test-Time Augmentation
I-Test-time augmentation (TTA) isebenzisa imodeli eqeqeshiwe ezinguqulweni ezimbalwa eziguquliwe zokokufaka okufanayo kanye nezilinganiso zokuqagela. Iqhinga elilula, elingenalo ukuqeqeshwa elivame ukuminyanisa amaphuzu ambalwa engeziwe okunemba futhi lenze izibikezelo zibe namandla kakhulu. I-Test-Time Augmentation iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-Test-Time Augmentation njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela oyifunayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Test-Time Augmentation athuthukisa izakhiwo, idatha, nokukhetha kwengqalasizinda ngokumelene nokuthembeka nezindleko. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka. Ngesikhathi esifanayo, Ukuthuthukisa ibhentshimakhi eyodwa kungafihla ubuthakathaka obubanzi besistimu. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
