Iyini ngempela i-algorithm ye-AI? 🧠
I -algorithm ye-AI inqubo esetshenziswa yikhompyutha ukuze:
-
Funda kudatha (noma impendulo)
-
Yazi amaphethini
-
Yenza izibikezelo noma izinqumo
-
Thuthukisa ukusebenza ngolwazi [1]
Ama-algorithm ajwayelekile anjengokuthi: “Hlunga lezi zinombolo ngokulandelana okukhuphukayo.” Sula izinyathelo, umphumela ofanayo njalo.
Ama-algorithm e-AI afana kakhulu nalawa: “Nazi izibonelo eziyisigidi. Sicela uthole ukuthi liyini ‘ikati’.” Bese lakha iphethini yangaphakathi evame ukusebenza . Ngokuvamile. Ngezinye izikhathi libona umcamelo othambile bese limemeza lithi “Ikati!” ngokuzethemba okuphelele. 🐈⬛
I-Algorithm ye-AI vs Imodeli ye-AI: umehluko abantu abawubonayo 😬
Lokhu kususa ukudideka okuningi
-
I-algorithm ye-AI = indlela yokufunda / indlela yokuqeqesha
("Lena yindlela esizibuyekeza ngayo kusukela kudatha.") -
Imodeli ye-AI = into eqeqeshiwe oyisebenzisayo kokufakwayo okusha
(“Lena yinto ebikezela manje.”) [1]
Ngakho-ke, i-algorithm ifana nenqubo yokupheka, futhi imodeli ukudla okuqediwe 🍝. Mhlawumbe isingathekiso esintengantengayo kancane, kodwa siyasebenza.
Futhi, i-algorithm efanayo ingakhiqiza amamodeli ahlukene kakhulu kuye ngokuthi:
-
idatha oyiphakelayo
-
izilungiselelo ozikhethayo
-
uqeqesha isikhathi esingakanani
-
ukuthi isethi yakho yedatha ayihlelekile kangakanani (i-spoiler: cishe ayihlelekile njalo)
Kungani i-algorithm ye-AI ibalulekile (noma ngabe awuyena "uchwepheshe") 📌
Ngisho noma ungalokothi ubhale umugqa wekhodi, ama-algorithm e-AI asakuthinta. Kuningi.
Cabanga: izihlungi zogaxekile, ukuhlolwa kokukhwabanisa, izincomo, ukuhumusha, ukwesekwa kwezithombe zezokwelapha, ukwenza ngcono umzila, kanye nokuthola amaphuzu engozi. (Hhayi ngoba i-AI "iyaphila," kodwa ngoba ukuqashelwa kwephethini ngezinga kuyigugu ezindaweni eziyisigidi ezibalulekile ngokuthula.)
Futhi uma wakha ibhizinisi, uphatha ithimba, noma uzama ukungaphazanyiswa yi-jargon, ukuqonda ukuthi iyini i -algorithm ye-AI kukusiza ukuthi ubuze imibuzo engcono:
-
Khomba ukuthi yiluphi ulwazi uhlelo olufunde kulo.
-
Hlola ukuthi ukucwasa kulinganiswa futhi kuncishiswa kanjani.
-
Chaza ukuthi kwenzekani uma uhlelo lungalungile.
Ngoba kuzoba yiphutha ngezinye izikhathi. Lokho akukhona ukuphelelwa yithemba. Yilokho okuyiqiniso.
Indlela i-algorithm ye-AI "efunda ngayo" (ukuqeqeshwa vs ukuphetha) 🎓➡️🔮
Izinhlelo eziningi zokufunda komshini zinezigaba ezimbili ezinkulu:
1) Ukuqeqeshwa (isikhathi sokufunda)
Ngesikhathi sokuqeqeshwa, i-algorithm:
-
ubona izibonelo (idatha)
-
yenza izibikezelo
-
kulinganisa ukuthi akulungile kangakanani
-
ilungisa amapharamitha angaphakathi ukuze inciphise iphutha [1]
2) Ukuphetha (ukusebenzisa isikhathi)
Isiphetho yilapho imodeli eqeqeshiwe isetshenziswa kokufakwayo okusha:
-
hlela i-imeyili entsha njengogaxekile noma cha
-
bikezela isidingo ngesonto elizayo
-
ilebula isithombe
-
dala impendulo [1]
Ukuqeqeshwa “ukufunda.” Ukuphetha “ukuhlolwa.” Ngaphandle kokuthi ukuhlolwa akupheli futhi abantu baqhubeka nokushintsha imithetho phakathi nohlelo. 😵
