Iyini i- Bayes theorem
Context:Ku-theory of probability and statistics, i- Bayes' theorem (noma umthetho ka- Bayes noma umthetho ka- Bayes), oqanjwe ngoThomas Bayes, uchaza amathuba okwenzeka kwesenzakalo, ngokusekelwe olwazini lwangaphambilini lwezimo ezingase zihlobene nesenzakalo. Isibonelo, uma ingozi yokuthuthukisa izinkinga zempilo yaziwa ukuthi iyanda ngokuguga, i- Bayes' theorem ivumela ingozi kumuntu oneminyaka ethile eyaziwayo ukuba ihlolwe ngokunembile ngokuyifaka ngokuhambisana nobudala bayo, kunokumane kucatshangwe ukuthi umuntu uyisibonelo sabantu bebonke.  Esinye sezicelo eziningi ze- Bayes' theorem yi- Bayesian inference, indlela ethile yokwenza izibalo. Lapho zisetshenziswa, amathuba ahlanganiswe kule theorem angase abe nokuchazwa okungenzeka okuhlukile. Ngokuhumusha okungenzeka kwe-Bayesian, i-theorem iveza ukuthi izinga lokukholelwa, elivezwe njengokungenzeka, kufanele lishintshe kanjani ngokunengqondo ukuze kucatshangelwe ukutholakala kobufakazi obuhlobene. I-Bayesian inference iyisisekelo sezibalo ze-Bayesian, icatshangwa yisiphathimandla esisodwa ngokuthi; "kwethiyori yamathuba ukuthi i-Pythagoras's theorem iyini i-geometry".
I - Bayes theorem isekelwe ekutheni kungenzeka yini ukuthi kwenzeke isenzakalo esithile.
