MIT idachotsa zosonkhanitsira Zithunzi Zing'onozing'ono pambuyo pozindikira mawu atsankho komanso onyoza

Massachusetts Institute of Technology zachotsedwa deta Zithunzi Zing'onozing'ono, zokhala ndi zofotokozera za zithunzi zazing'ono 80 miliyoni za 32x32. Setiyi idasamalidwa ndi gulu lomwe likupanga matekinoloje owonera makompyuta ndipo lakhala likugwiritsidwa ntchito kuyambira 2008 ndi ofufuza osiyanasiyana pophunzitsa ndi kuyesa kuzindikira kwazinthu pamakina ophunzirira makina.

Chifukwa chochotsera chinali kuzindikira kugwiritsa ntchito mawu atsankho komanso ankhanza m'malemba ofotokozera zinthu zomwe zawonetsedwa pazithunzizo, komanso kukhalapo kwa zithunzi zomwe zidawonedwa ngati zokhumudwitsa. Mwachitsanzo, panali zithunzi za ziwalo zoberekera zokhala ndi mawu osalongosoka, zithunzi za akazi ena zimatchedwa “mahule,” ndipo mawu osaloleka m’chitaganya chamakono kwa anthu akuda ndi Asiya anagwiritsidwa ntchito.

Komabe, chikalata chotchulidwa ndi MIT chikuwonetsanso mavuto aakulu kwambiri ndi zosonkhanitsa zoterezi: matekinoloje a masomphenya apakompyuta angagwiritsidwe ntchito popanga machitidwe ozindikira nkhope kuti afufuze oimira magulu a anthu omwe amaletsedwa pazifukwa zina; neural network yopanga zithunzi imatha kupanganso choyambirira kuchokera ku data yosadziwika.

Chifukwa chomwe chimawonekera kwa mawu olakwika chinali kugwiritsa ntchito njira yodzipangira yokha yomwe imagwiritsa ntchito maulalo a semantic kuchokera ku nkhokwe yachingerezi ya lexical database kuti agawane. Mawu, yopangidwa m'ma 1980 ku yunivesite ya Princeton. Popeza sizingatheke kuyang'ana pamanja kukhalapo kwa zilankhulo zonyansa muzithunzi zazing'ono 80 miliyoni, adaganiza zotsekereza mwayi wofikira ku database. MIT idalimbikitsanso ofufuza ena kuti asiye kugwiritsa ntchito zosonkhanitsira ndikuchotsa makope ake. Mavuto ofananawo amawonedwa m'nkhokwe yayikulu kwambiri yazithunzi ImageNet, yomwe imagwiritsanso ntchito anangula kuchokera ku WordNet.
