Amamodeli Womhlaba kanye Nabalingisi Abafundile
Imodeli yomhlaba inethiwekhi ye-neural efunda ukubikezela ukuthi indawo ishintsha kanjani ngokuhamba kwesikhathi, ivumele i-AI 'icabange' imiphumela yesikhathi esizayo ngaphambi kokuthatha isinyathelo.
Uhlolojikelele
Learned simulators take this further, generating interactive, playable environments from data instead of being hand-coded by engineers.
I-Deep Dive
Kunokuba ubambe ngekhanda lokho okumele ukwenze, imodeli yomhlaba ithwebula ukuguquguquka kwendawo: uma kubhekwa isimo samanje nesenzo esihlongozwayo, ibikezela ukubonwa okulandelayo. Iphepha langonyaka lika-2018 elithi 'Amamodeli Womhlaba' ka-Ha no-Schmidhuber bacindezele amafreyimu egeyimu nge-autoencoder, amodela amandla awo ngenethiwekhi ephindelelayo, futhi aqeqeshe isilawuli cishe ngokuphelele ngaphakathi kwaleli 'phupho' elifundiwe. Ulayini we-DeepMind's Dreamer ufunda amandla aguquguqukayo nezinhlelo ngokukhipha ama-trajectories acatshangelwayo, futhi i-DreamerV3 inekhono lemisebenzi eyahlukene - ngisho nokuqoqa amadayimane ku-Minecraft kusukela ekuqaleni. Kamuva nje, i-Genie ka-Google ikhiqiza imihlaba ye-2D elawulekayo ngezithombe namavidiyo angenamalebula, futhi i-GameNGen ikhiqize kabusha igeyimu ye-DOOM ngesikhathi sangempela isebenzisa kuphela imodeli yokusabalalisa. Isikhalazo: ama-ejenti angafunda noma ahlolwe ngomcabango oshibhile, osheshayo esikhundleni seqiniso eliyingozi, elihamba kancane.
I-Technical Insight
Amamodeli omhlaba ngokuvamile ahlanganisa ukubonwa kwe-high-dimensional kusimo esifihlekile esihlangene, bese ufunda umsebenzi woshintsho obikezela isimo esilandelayo esicashile kanye nomvuzo esenzweni. Ukuhlela kusebenzisa 'ukukhishwa': ukucabangela ukulandelana kwezenzo okuningi phambili nokukhetha okungcono kakhulu, noma ukuqeqesha inqubomgomo kudatha ecatshangelwayo. Izinguqulo zesimanje zisebenzisa ama-transformer noma ukusakazwa kwevidiyo ukuze zibikezele ozimele ngokuqondile, ezibekwe esenzweni somsebenzisi, zifinyelela ukukhiqizwa kohlaka ngohlaka olusebenzisanayo.
I-Strategic Impact

Kukusiza ukuthi uhlukanise izimangalo ezicacile zobuchwepheshe kusukela olimini lokumaketha.
Izindleko kanye nesabelomali
Ungabuza imibuzo yokusebenzisa kangcono ngaphambi kokusebenzisa imali noma isikhathi.
Ithimba kanye nokusebenza komsebenzi
Amaqembu anokuqonda okwabiwe enza izinqumo ezingcono zomkhiqizo, inqubomgomo, nokufunda.
Ikusasa Lamamodeli Omhlaba kanye Nabalingisi Abafundile
Amamodeli omhlaba aba ingqikithi yamarobhothi nokukhiqizwa kwegeyimu: athembisa ukufunda okusebenzisa idatha ngendlela efanele lapho ukusebenzisana kwangempela kubiza khona, kanye nezindawo ezidlalekayo ezikhiqizwa lapho undiza. Lindela ukuthembeka okuphezulu, umkhathizwe omude, amamodeli evidiyo anesimo sokwenza okuthile, ukuhlanganiswa okuqinile nama-ejenti ahlelayo, futhi usebenzise 'njengezilingisi ze-neural' zokuqeqesha izinqubomgomo zokuzishayela nokuzikhohlisa. Izinselele ezivulekile zihlanganisa ukungaguquguquki kwesikhathi eside, ukugwema i-physics ekhohliwe, kanye nokukhulisa inkumbulo.
Ukuqaliswa Komhlaba Wangempela
U-Ha kanye no-Schmidhuber baqeqesha umenzeli womjaho wezimoto cishe ngaphakathi kwephupho lakhe elifundiwe lemvelo
I-DeepMind's DreamerV3 iqoqa amadayimane eMinecraft kusukela ekuqaleni ngokuhlela emcabangweni
I-Genie ka-Google ikhiqiza umhlaba weplathifomu ye-2D edlalekayo ngesithombe esisodwa sokwaziswa
I-GameNGen isebenzisa inguqulo edlalekayo ye-DOOM ngesikhathi sangempela, namafreyimu akhiqizwa imodeli yokusabalalisa
Izingozi & Guardrails
Amaqembu ahlukene angasebenzisa igama elifanayo ngokuhlukile, ngakho chaza ububanzi kusenesikhathi.
Amabhentshimakhi angabukeka eqinile kuyilapho ukusebenza komhlaba wangempela kungalingani.
Ukuziba ikhwalithi yedatha nezinhlelo zokuhlaziya kuvame ukudala imiphumela entekenteke.
Ukuqalisa Umhlahlandlela
Qala ngencazelo yolimi olulula yomphumela oyidingayo.
Khetha imethrikhi eyodwa yempumelelo nesimo esisodwa sokuhluleka ngaphambi kokuhlolwa.
Qalisa umshayeli omncane onedatha emele, hhayi isethi yedemo ephucuziwe.
Bhala lapho amamodeli Womhlaba kanye nezifanisi ezifundiwe kusiza khona nalapho izindlela ezilula zingcono khona.

Imibuzo evame ukubuzwa
What is World Models and Learned Simulators?
Imodeli yomhlaba inethiwekhi ye-neural efunda ukubikezela ukuthi indawo ishintsha kanjani ngokuhamba kwesikhathi, ivumele i-AI 'icabange' imiphumela yesikhathi esizayo ngaphambi kokuthatha isinyathelo. Izilingisi ezifundiwe ziqhubekisela phambili lokhu, zenze izindawo ezisebenzisanayo, ezidlalekayo kusuka kudatha esikhundleni sokwenziwa amakhodi ngesandla ngonjiniyela.
Uyini umsebenzi oyinhloko wemodeli yomhlaba?
Imodeli yomhlaba ifunda ukuguquguquka kwemvelo: ukusuka esimweni samanje nasesenzweni ibikezela ukubonwa okulandelayo (futhi ngokuvamile iklomelise), ivumela ukukhishwa okucatshangelwayo.
Ephepheni lika-2018 'Amamodeli Womhlaba' ka-Ha no-Schmidhuber, isilawuli sasiqeqeshwe kuphi kakhulu?
I-ejenti yafunda ukwenza cishe ngokuphelele ngaphakathi kokuguquguquka okufihliwe okufundiwe ('iphupho'), yase idluliselwa endaweni yangempela.
Yikuphi okuphawulekayo okuzuzwe yi-DeepMind's DreamerV3?
I-DremerV3 ifunde amandla acashile futhi yasebenzisa ukukhishwa okucatshangelwayo ukuze ibe yingcweti emisebenzini eminingi, okuhlanganisa nokuthola amadayimane ku-Minecraft ngaphandle kwedatha yomuntu noma ikharikhulamu.
Yenzani i-Genie ye-Google?
I-Genie iyindawo esebenzisanayo efunda kuvidiyo engenamalebula ukukhiqiza imihlaba ye-2D elawulekayo.
Amamodeli amaningi omhlaba ayigcina kanjani inkinga yokuqagela ibambeka kokufakwayo kobukhulu obuphezulu njengezithombe?
Ukubuka kubhalwa ngekhodi kusimo esifihlekile sohlangothi oluphansi, futhi umsebenzi woshintsho ubikezela isimo esicashile esilandelayo, okwenza ukukhishwa kusebenze kahle.
