Pfupiso

Inopa masimba A / B kuyedza, kurudziro, uye kusarudzwa kwepamhepo ad.

Kudzika Kwakadzika

Iro zita rinobva kune anobhejera akatarisana akati wandei slot machines (one-armed bandits), imwe neimwe ine isingazivikanwe kuhwina mwero, uyo anoda kuwedzera mubairo pane akawanda anodhonza. Iko kunetsa kwepakati ndiko kuongorora-kushandisa tradeoff: ramba uchidhonza ruoko rwunotaridzika zvakanyanya, kana kuenzanisa maoko asina chokwadi kuti udzidze zvakawanda. Kuita kunoyerwa nekuzvidemba, mukaha unowedzera pakati pemibairo yako uye kugara uchitora ruoko rwechokwadi rwechokwadi; yakanaka algorithms inowana kuzvidemba iyo inokura chete logarithmically muhuwandu hwekutenderera. Mazano echinyakare anosanganisira epsilon-anokara (shandisa, asi ongorora chero nekamwe kadiki), Upper Confidence Bound (tora ruoko rune fungidziro yepamusoro), uye Thompson sampling (sample kubva kune imwe neimwe yeruwoko kutenda kwemashure uye tamba mukundi). Contextual mabhanditi anowedzera izvi nekushandisa maficha emamiriro acho kusarudza.

Kuitwa muNyika yeChokwadi

Saiti yenhau inoshandisa makororo kusarudza kuti ndeupi musiyano wemusoro wekuratidza, nekukasira kushandura traffic kune iyo vhezheni inowana mabhatani mazhinji.

Yepamhepo ad chikuva inogovera zvinoonekwa kune vese vanogadzira neThompson sampling kuti uwedzere kubaya-kuburikidza uchiri kuyedza kushambadza kutsva.

Chiyedzo chekiriniki chinogadzirisa chinopa varwere vazhinji kurapwa kunoratidza mhedzisiro iri nani, kuderedza kuratidzwa kune yakaderera maoko.

Yekutepfenyura sevhisi tunes ekurudziro zvigunwe pamushandisi wega wega ane mamiriro mabhanditi anoverenga ekuona-nhoroondo maficha.

Ramangwana Remakororo Akawanda

Makororo ari kupararira mukudzidza kwekusimbisa, kwavanoumba yakapusa bhuroka yekuvaka, uye muhukuru-hukuru hwemunhu ane mamiriro uye neural bandits anoverenga akapfuma maficha. Tsvagiridzo inoshingaira inonangana nemibairo isiri-yakamira iyo inofamba nekufamba kwenguva, makororo ane kuchengeteka kana zvipingamupinyi zvakanaka, uye kubatanidza makororo nekudzidza kwakadzama kwekumiririra. Tarisira ivo vakanyudzwa mumakiriniki ekuyedzwa, mitengo ine simba, uye LLM masisitimu anosarudza kukurudzira kana maturusi pamhepo uchidzora kuzvidemba.

Kuzvishandisa

Nei zvichikosha

  • Mutengo uye bhajeti. Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore.
  • Sarudzo dzakajeka. Dzidzo yehunyanzvi inobatsira zvikwata kusarudza murwi wakakodzera, kwete iwo mutsva chete.
  • Kudzora kwemhando yepamusoro. Sarudzo dzeinjiniya dziri nani dzinoderedza zviitiko zvekuvimbika mukugadzira.

Chenjera

  • Kugadzirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba.
  • Infrastructure uye mari yekugadzirisa inowanzotarisirwa pasi.
  • Chengetedzo uye kucherechedzwa mapundu anogona kukura sezvo masisitimu anowedzera kuoma.
