Setha theory: nobukhulu bayo

Imfundiso yokuziphendukela amasethi usongene uvezwa kwesigaba wezibalo isicelo, okuyinto izinikele izindlela sokuhlaziya yalezi ukungaqiniseki, echaza nokungaqiniseki nezenzakalo zangempela futhi izinqubo usebenzisa imiqondo amasethi kungekho imingcele ecacile.

Classical isethi theory ichaza ubulungu yesici esithile isethi esinikeziwe. Kulokhu, ngaphansi ubulungu wamukela umqondo ngokuya kanambambili, okusho kukhona isimo esicacile noma sakhi umbuzo fanele noma ingeyona.

Setha Umbono ophathelene no-ukuntuleka ukucaciseleka inikeza ukuqonda letihlungiwe uyabanikeza malware ngesici esithile ukuze isethi, kanye nezinga izesekeli zawo ukuba achazwe usebenzisa umsebenzi elifanele. Ngamanye amazwi, ushintsho kusuka okuqondene isede enikelweko izakhi ezithile ezakho akwenzeki ngokuphazima kweso, kodwa kancane kancane, usebenzisa indlela probabilistic.

nelemuko elaneleko loku abacwaningi angaphandle kanye ezifuywayo kusikisela kungathembeki futhi ukungeneli indlela probabilistic, ithuluzi ukuxazulula izinkinga ohlobo wavuma olwakhiwe. Ukusetshenziswa izindlela kwezibalo ukuxazulula izinkinga zalolu hlobo kuholela ukuhlanekezela enkulu ekwakhiweni yokuqala inkinga. It nemibi kanye nemikhawulo ezihlobene nokusetshenziswa izindlela zasendulo izimo zokuxazulula izinkinga azenzeki ifomu semistructured, zibangelwa "isimiso ukungavumelani", okuyinto washayelwa imfundiso yokuziphendukela amasethi usongene, akhiwa LA Emshabam.

Ngakho-ke, abanye abacwaningi abathi ngokwezinga angaphandle kanye ezifuywayo baye basungula izindlela ngoba kucatshangwa ingozi utshalomali amaphrojekthi kanye nekusebenta usebenzisa amathuluzi usongene isethi theory. Ziyakwazi ukufaka esikhundleni indlela okungenzeka ukusatshalaliswa, kuba izabelo kungenzeka, elichazwa umsebenzi ubulungu yohlobo usongene.

Basics of isethi Inkolelo-mbono esekelwe amathuluzi ahambisana izindlela izinqumo endaweni lingaqinisekile. Ukusebenzisa kwabo kube semthethweni Kusolwa imingcele kokuqala ukusebenza target ukuma njengoba vector of isikhawu usongene (amagugu isikhawu). Imininingwane ngamunye isikhawu kungakhawulwa elinesimo degree yokungaqiniseki.

Ukusebenzisa izibalo lapho esebenza enjalo ngezikhathi usongene, kungenzeka ochwepheshe etholwe isikhawu usongene ukuze target ethile. Ngokusekelwe kokuqala ulwazi, isipiliyoni kanye umuzwa, izazi anganika izici qualitative ambalwa of imingcele (ngezikhawu) yamanani kungenzeka zasendle kanye nemingcele yamanani yabo kungenzeka.

Setha theory kungenziwa ngenkuthalo lisetshenziswe umkhuba futhi inkolelo-mbono yokuziphendukela ukulawula izinhlelo ku ezezimali kanye umnotho ukuhlangabezana nezinselele ukungaqiniseki, inqobo izinkomba eziyisisekelo. Ngokwesibonelo, inqubo efana amakhamera ezinye imishini yokuwasha, ifakwe abalawuli usongene.

Esifundweni sezibalo, elibekwe theory ehlongozwayo ngu LA Emshabam, ivumela ukuchaza ulwazi usongene kanye imiqondo, zokuzisebenzisa futhi wenze iziphetho ezingacacile. Siyabonga mbono, esekelwe izindlela wokwakha izinhlelo usongene ngosizo lobuchwepheshe be-computer kakhulu sithuthukiswe isicelo lwamakhompyutha. Muva nje, ukuphathwa amasethi usongene ingenye izindawo eziphumelela kakhulu ucwaningo. Iwusizo usongene ukulawula eyinkimbinkimbi kubonakala izinqubo ezithile ngokuhlaziya isikhundla usebenzisa amasu ambalwa. Futhi amasethi usongene elisetshenziswa ekuphathweni eliphezulu incazelo yaleli imithombo ehlukahlukene yokwaziswa.
