Uhlolojikelele
I-Group Relative Policy Optimization (GRPO) iyindlela yokuqinisa yokufunda yamamodeli olimi ashuna kahle ahlulela impendulo ngayinye ngokumelene neqembu lezimpendulo eziyizelamani ekwazisweni okufanayo, esusa inethiwekhi yenani ehlukile esetshenziswa i-PPO. Kwaduma njengeqhinga lokuqeqesha eliyisisekelo ngemuva kwamamodeli okucabanga we-DeepSeek.
I-Group Relative Policy Optimization iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
I-GRPO iwuhlobo oluhlukile lokufunda okuqiniswa kwenqubomgomo-gradient okudizayinelwe ukwenza ukulungisa kahle kwe-RL kwamamodeli wezilimi ezinkulu kushibhe futhi kuzinze kakhudlwana. I-PPO evamile idinga 'umgxeki' ofundiwe (imodeli yenani), cishe enkulu njengenqubomgomo ngokwayo, ukuze ilinganisele ukuthi ithokheni ngalinye lihle kangakanani. I-GRPO isusa lowo mgxeki ngokuphelele. Emyalweni ngamunye yenza amasampula eqembu lokuqedela (ithi 8-64), iwathole wonke ngesignali yomklomelo, bese ihlanganisa inzuzo yokuqeda ngakunye ngokumisa umvuzo wayo ngokumelene nesilinganiso nokuchezuka okujwayelekile kweqembu. Izimpendulo ezingaphezu kwesilinganiso ziyaqiniswa futhi ezingaphansi kwe-avareji ziyacindezelwa. Itemu le-KL-divergence ligcina imodeli iseduze nenqubomgomo yereferensi. Yethulwe yi-DeepSeek, inikeze amandla i-DeepSeekMath kanye nemodeli ye-DeepSeek-R1 yokucabanga.
I-Technical Insight
Umbono obalulekile ukufaka isisekelo senani le-PPO esikhundleni sesisekelo seqembu le-Monte Carlo. Eqenjini lemiphumela enemiklomelo engu-r_i, inzuzo ngayinye ithi A_i = (r_i - mean(r)) / std(r). Lowo mphumela ojwayelekile uphindaphinda isilinganiso samathuba asikiwe, ncamashi njengaku-PPO, kanye nenhlawulo ye-KL ngokumelene nemodeli yereferensi efriziwe inqamula ukukhukhuleka. Ngoba akekho umgxeki oqeqeshiwe, inkumbulo nokubala cishe kuhhafu, futhi ukujwayela ngokushesha kunikeza izinzuzo ezilinganiselwe ngokwemvelo, zokuhlukahluka okuphansi.
I-Mastering Group Relative Policy Optimization
I-Group Relative Policy Optimization (GRPO) iyindlela yokuqinisa yokufunda yamamodeli olimi ashuna kahle ahlulela impendulo ngayinye ngokumelene neqembu lezimpendulo eziyizelamani ekwazisweni okufanayo, esusa inethiwekhi yenani ehlukile esetshenziswa i-PPO. Kwaduma njengeqhinga lokuqeqesha eliyisisekelo ngemuva kwamamodeli okucabanga we-DeepSeek. I-Group Relative Policy Optimization iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha Ukuthuthukiswa Kwenqubomgomo Yeqembu njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Group Relative Policy Optimization 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.
