Imibare yo kwitiranya ibintu
Matrix yo kwitiranya ni imbonerahamwe yoroshye ivunagura ibyateganijwe muburyo bukwiye kandi butari bwo kuri buri cyiciro.
Incamake
It is the raw scoreboard from which nearly every other classification metric is calculated.
Kwibira cyane
Matrix yo kwitiranya ni gride igereranya ibirango byahanuwe nibirango nyabyo. Kubyiciro bibiri bifite selile enye: Ibyiza byukuri (byahanuwe neza nibyiza), Ibibi byukuri (byahanuwe neza), Ibinyoma (Ibibi byashyizwe ahagaragara nabi, 'Ubwoko bwa I ikosa'), hamwe nibibi (ibyiza byabuze, 'Ikosa ryubwoko bwa II'). Uhereye kuri iyi mibare ine ukuramo ubunyangamugayo ((TP + TN) / yose), ibisobanuro (TP / (TP + FP)), kwibutsa cyangwa kwiyumvisha ibintu (TP / (TP + FN)), umwihariko (TN / (TN + FP)), n'amanota F1 (bisobanura guhuza neza no kwibuka). Kubibazo bifite ibyiciro birenga bibiri, matrix iba N-by-N, aho diagonal ifite ubuhanuzi bukwiye kandi selile zitari diagonal zigaragaza neza ibyiciro bitiranya nabandi.
Ubushishozi
Imbaraga za matrix nuko irinda imiterere yamakosa numero imwe yukuri ihishe. Moderi ebyiri zifite 90% zisa neza zirashobora kugira ibipimo bitandukanye byibinyoma-bibi, bifite akamaro kanini mugihe isuzumwa rya kanseri ryabuze ritwara ibirenze gutabaza. Ku murongo w'ikoraniro akenshi ugereranya ibyiciro byukuri hamwe ninkingi zahanuwe (nubwo amasomero amwe ahindura ibi), burigihe rero reba ibirango bya axis mbere yo kubara neza nibuka kuva muri selile.

Ejo hazaza h'imibare yo kwitiranya ibintu
Matrices yo kwitiranya izagumaho ishingiro, ariko ibikoresho birabakungahaza: guhuza, gushushanya bisanzwe, ubushyuhe buri cyiciro cyo gusenyuka kubirango binini byashyizweho, hamwe na matrica iremereye igwiza buri bwoko bwikosa nigihano nyacyo cyisi. Mu igenzura ryuburinganire, abimenyereza ubu barabaze matrices itandukanye yo kwitiranya buri tsinda rito kugirango bagaragaze ibipimo byamakosa atangana. Tegereza gukomeza kwishyira hamwe mubyitegererezo byerekana aho ukanze selile igaragara ingero zifatika zitari zo kugenzura.

Kugenzura igikoresho cyo gusuzuma kwa muganga usuzuma ibibi - abarwayi bafite indwara icyitegererezo cyatangaje ko ari cyiza

What is Confusion Matrices?
Matrix yo kwitiranya ni imbonerahamwe yoroshye ivunagura ibyateganijwe muburyo bukwiye kandi butari bwo kuri buri cyiciro. Nibipapuro bibisi biva hafi ya buri cyiciro cyo kubara kibarwa.
Muri matrise yo kwitiranya binary, Ibibi Byibeshya ni iki?
Ibibi Byibeshya nibyiza mubyukuri icyitegererezo cyabuze nukwita ko ari bibi - urugero, umurwayi urwaye yatangaje ko ari muzima.
Nibihe bipimo bipima igipimo cyiza cyiza icyitegererezo cyerekana neza?
Ibuka (nanone bita sensitivite cyangwa igipimo nyacyo cyiza) ni TP / (TP + FN) - umugabane wibyiza nyabyo icyitegererezo cyafashwe.
Muri matrix yo kwitiranya ikibazo hamwe namasomo 5, selile ya diagonal igereranya iki?
Muri matrike ya N-by-N diagonal ifata imanza aho ibyiciro byahanuwe bihuye nicyiciro nyacyo - ni ukuvuga, guhanura neza.
Ni ukubera iki ubunyangamugayo bwonyine bushobora kujijisha nta matrise yo kwitiranya?
Moderi ebyiri zifite ubunyangamugayo bumwe zirashobora gukwirakwiza amakosa yabo muburyo butandukanye; matrix yo kwitiranya yerekana niba amakosa ahanini ari impuruza y'ibinyoma cyangwa ibyiza byabuze.
Amanota ya F1 nuburyo bwo guhuza ni ubuhe bipimo bibiri?
F1 ikomatanya neza kandi yibuke mumubare umwe ukoresheje uburyo bwo guhuza, bihana ubusumbane bukomeye hagati yabyo.
