Hababka Jilaaga-Naqdinta
Hababka Jilaa-Critic waxay isku daraan laba arday: 'jilaa' oo doorta ficillada iyo 'dhaleec' kaas oo qiimeeya sida ay u fiicnaayeen ficilladaas.

This pairing makes reinforcement learning more stable and sample-efficient than using either approach alone.
quusid qoto dheer
Xoojinta barashada waxay leedahay laba qaab oo balaadhan: habab ku salaysan siyaasad oo si toos ah u baranaya waxa la qabanayo, iyo habab ku salaysan qiimaha oo barta sida dawladuhu u wanaagsan yihiin. Jilaa-Critic ayaa isku dhejinaya iyaga. Jilaagu waa siyaasad soo saarta ixtimaalka ficilka; naqdintu waa hawl qiimi leh oo qiyaaseysa soo laabashada la filayo. Tallaabo kasta ka dib, naqdiyehu waxa uu xisaabiyaa khalad kala duwanaansho ku meel gaar ah oo tilmaamaya in natiijadu ka wanaagsan tahay ama ka xun tahay sidii la filayay. Jilaagu wuxuu u adeegsadaa khaladkan si uu ugu riixo siyaasadiisa ku wajahan ficilada ka soo horjeeda filashada kana fogaato kuwa wax qabadkoodu hooseeyo. Sababtoo ah naqdigu waxa uu bixiyaa sal hoose oo kala duwanaansho ah, qiyaasaha jilitaanka jilaagu aad ayay uga yar yihiin buuqa marka loo eego hababka saafiga ah ee siyaasad-sii-xoojinta sida REINFORCE, iyada oo wali la tacaalayo goobaha waxqabadyada joogtada ah ee hababka qiimaha-kaliya sida Q-Learning ay u arkaan wax dhib badan.
Aragtida Farsamada
Jilaagu waxa uu cusboonaysiiyaa cabiraadiisa siyaasada ee jihada jaan-goynta siyaasada, lagu cabiray faa'iidada A(s,a) = Q(s,a) -V(s), kaas oo naqdigu ku qiyaaso (badanaa iyada oo loo marayo qaladka TD r + gamma*V(s') - V(s)). Faa'idadu waxay cabbirtaa inta uu ficilku uga wanaagsan yahay celceliska gobolka, sidaa awgeed faa'iidooyinka togan waxay xoojiyaan ficillada kuwa xununa way cabbudhiyaan. Dhaliisha si gaar ah ayaa loogu tababaray si loo yareeyo khaladkeeda TD.

Qiimaha iyo miisaaniyada
Go'aamada qaab-dhismeedku waxay horseedaan waxqabadka iyo kharashka hawlgalka sannadaha.
Go'aamo cad
Waxbarashada farsamada waxay ka caawisaa kooxaha inay doortaan xidhmo sax ah, ma aha oo kaliya kan ugu cusub.
Xakamaynta tayada
Doorashooyinka injineernimada ee wanaagsan waxay yareeyaan shilalka la isku halleyn karo ee wax soo saarka.
Mustaqbalka Hababka Jilaaga-Naqdinta
Jilaa-Critic waa laf-dhabarta ugu casrisan ee qoto dheer RL. Algorithms sida A3C, A2C, PPO, SAC, iyo DDPG dhamaantood way ku dhismaan, iyaga oo ku dara khiyaamo ay ka mid yihiin ujeedooyinka la jarjaray ee cusbooneysiinta xasilloon, gunnada sahaminta ee entropy, iyo jilayaasha barbar socda ee wax soo saarka. Ka filo koritaanka sii socota ee robotics-ka, wakiilada ciyaarta baaxadda leh, iyo RL jawaab celinta aadanaha ee habaynta moodooyinka luqadda, halkaas oo xasilloonida iyo waxtarka muunadku ay ugu muhiimsan yihiin.
Dhaqangelinta Adduunka-dhabta ah
Tababarka hubka robotka iyo kontaroolayaasha goobta oo leh wareegyo wadajir ah oo wadajir ah (tusaale, isticmaalaya PPO ama SAC)
Isku toosinta moodooyinka luqadaha waaweyn iyada oo loo marayo RLHF, halkaas oo PPO (habka jilaa- naqdinaya) ay hagaajiso jawaabaha lidka ku ah qaabka abaalmarinta

Su'aalaha soo noqnoqda
What is Actor-Critic Methods?
Hababka Jilaa-Critic waxay isku daraan laba arday: 'jilaa' oo doorta ficillada iyo 'dhaleec' kaas oo qiimeeya sida ay u fiicnaayeen ficilladaas. Lammaanayntani waxay ka dhigaysa xoojinta barashada mid deggan oo muunad-wax-ku-ool ah marka loo eego isticmaalka hab kaligiis.
Habka Jilaaga-Critic, waa maxay doorka 'dhaleeceeyaha'?
Naqdintu waxay barataa shaqada qiimaha waxayna soo saartaa calaamada qiimaynta (sida qaladka TD) kaas oo u sheegaya jilaaga in ficilladiisu ay ka fiicnaayeen ama ka xun yihiin sidii la filayay.
Maxay 'faa'iidada' A(s,a) = Q(s,a) - V(-yada) cabbiraysaa?
Faa'iidada ayaa go'doominaysa inta ficil gaar ah uu ka sarreeyo natiijada caadiga ah ee gobolkaas, taasoo siinaysa calaamad nadiif ah oo ka badan soo celinta cayriin.
Maxay ku darista dhaleecayn u dhimaysaa kala duwanaanshiyaha marka la barbar dhigo hababka saafiga ah ee siyaasad-sii-xoojinta sida REINFORCE?
Kala goynta qiyaasaha qiimaynta dhaleecaynta iyada oo gundhig ahaan hoos u dhigaysa kala duwanaanshaha qiyaasaha gradient iyada oo aan lagu darin eex, barashada xawaaraha.
Awooddee ayay hababka Jilaaga-Critic leeyihiin hababkaas qiimaha leh ee ku salaysan sida Q-Learning?
Sababtoo ah jilaagu wuxuu si toos ah u cabbirayaa siyaasadda, waxay soo saari kartaa ficillo joogto ah (tusaale, torques wadajir ah) iyada oo aan loo baahnayn wax ka badan ficillo badan oo aan dhammaad lahayn.
Calaamadee uu jilaagu caadi ahaan u isticmaalo si uu u cusboonaysiiyo siyaasadiisa?
Jilaagu waxa uu ku hagaajiyaa siyaasadiisa jihada ay soo jeediso faa'iidada/TD-khalad calaamada dhaleeceynta, iyada oo xoojinaysa ficilada la filayo.
