Bal qiyaas in aad waydiiso robot: "Haye, ka soo qaad koobka cas jikada oo keen halkan." Ma fududa? Laakiin AI tani waxay ku lug leedahay fahamka luqadda, dhex mara meel bannaan, garashada walxaha, iyo bixinta jawaab celin dhammaan waqtiga dhabta ah. Tani waa dhab ahaan waxa aan wax kaga qabtay halkaas oo aan ku dhisnay wakiil wada hadal oo oo fahmi kara tilmaamaha, dhex mari kara deegaankiisa, la falgeli kara walxaha, oo dib ula xidhiidhi kara. Alexa Prize SimBot Challenge qaabaysan Waa kuwan sida aan uga dhignay in ay u shaqeyso annagoo adeegsanayna BERT, xoojinta barashada, iyo barashada mashiinka farsamada. Aynu soo marno dhibaatooyinkii kala duwanaa iyo sidii aynu mid walba uga hortagnay. Fahamka Luqadda ee BERT Luqadda dabiiciga ahi waa qas waxayna noqon kartaa mid aad u adag. Haddaan nahay bini'aadam waxaan leenahay laakiin sidoo kale waxaan dhihi karnaa Robotku waa inuu macne ka soo saaraa weedho kala duwan. Tag talaajadda qaboojiyaha raadi oo fur. Si tan loo sameeyo, waxaanu isticmaalnay BERT (Wakiilada Encoder-ka laba jiho ee Transformers) si aan ugu beddelno tilmaamaha qoraalka amarro habaysan, si ay ugu fududaato inay u fuliso si isku xigta.
