Uhlolojikelele
Izinga lokushisa nesampula amadayili alawula ukuthi 'okungahleliwe' noma 'aphephe' kangakanani amagama emodeli yolimi. Banquma ukuthi uthola impendulo efanayo ebikezelwayo ngaso sonke isikhathi noma amabinzana amasha, ahlukahlukene.
Ithempelesha nesampula kuyingxenye yesitaki solimi-AI esisetshenziselwa ukufunda, ukukhiqiza, ukuhlukanisa, nokuguqula umbhalo nenkulumo ngezinga eliphezulu.
I-Deep Dive
Esinyathelweni ngasinye, imodeli yolimi ayikhiphi igama ngokuqondile — ikhiqiza amaphuzu ('ilogit') yawo wonke amathokheni kusilulumagama sayo, i-softmax eshintsha ibe ukusabalalisa okungenzeka. Ukusampula yindlela ithokheni elandelayo ekhethwa ngayo kulokho kusatshalaliswa. Izinga lokushisa lilungisa kabusha ukusatshalaliswa ngaphambi kokukhetha: izinga lokushisa eliphansi lenza ukukhetha okuphezulu kulawule, ngakho okukhiphayo kugxilile futhi kuphindaphindeka; izinga lokushisa eliphezulu liyayenza ibe isicaba, ivumele amathokheni angenakwenzeka ukuba angene ezinhlobonhlobo eziningi (namanye amaphutha). Izihlungi ezimbili ezidumile zinciphisa ichibi kuqala. I-Top-k igcina kuphela amathokheni angu-k okungenzeka kakhulu. I-Top-p, noma i-nucleus sampling, igcina isethi encane yamathokheni amathuba awo afinyelela ku-p (yithi 0.9), ngakho ichibi liyakhula lapho imodeli ingaqiniseki futhi incipha uma iqiniseka. Ngokuhlangene lezi zilungiselelo zihweba ngokwethembeka ngokumelene nokudala.
I-Technical Insight
Izinga lokushisa lisebenza ngokuhlukanisa ilogi ngayinye ngo-T ngaphambi kwe-softmax: amathuba alingana ne-exp(logit / T). T ngaphansi kuka-1 ulola izikhala ukuze ithokheni ephezulu ibuse; T ngenhla 1 incipha izikhala futhi inciphise ukusatshalaliswa. Ku-T eduze no-0 imodeli iba nomhobholo, ihlale ithatha ithokheni eyodwa okungenzeka kakhulu. I-Top-k ihlanganisa isibalo sekhandidethi enombolweni engashintshi, kuyilapho i-top-p isetha ukunqamuka kwamathuba akhulayo, ngakho isibalo sekhandidethi lakhona sivumelana nendlela imodeli eqiniseka ngayo kuleso sinyathelo.
I-Mastering Temperature kanye Nesampula
Izinga lokushisa nesampula amadayili alawula ukuthi 'okungahleliwe' noma 'aphephe' kangakanani amagama emodeli yolimi. Banquma ukuthi uthola impendulo efanayo ebikezelwayo ngaso sonke isikhathi noma amabinzana amasha, ahlukahlukene. Ithempelesha nesampula kuyingxenye yesitaki solimi-AI esisetshenziselwa ukufunda, ukukhiqiza, ukuhlukanisa, nokuguqula umbhalo nenkulumo ngezinga eliphezulu. Ukuze wakhe ukuqonda okujulile, phatha i-Temperature neSampling njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa iziyalezo zedizayini ye-Temperature kanye Nesampula, ukubuyisa, nokubuyekeza ama-loops njengohlelo olulodwa lokuxhumana oludidiyelwe. 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.
Ukugeleza komsebenzi wolimi kungahamba ngokushesha ngaphandle kokudela ukuvumelana. Ngesikhathi esifanayo, amaqiniso Akhohliwe angafaka imibiko buthule, ukugeleza kosekelo, noma imiphumela yocwaningo. 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.
