Ukuhlukunyezwa Kuhlaziya Ubudlelwano Phakathi Kwezinguquko
Ukuhlukumeza kuyindlela yokwebiwa kwedatha esetshenziselwa ukubikezela ububanzi bezinombolo zamanani (okubizwa nangokuthi amagugu aqhubekayo ), unikezwa i-dataset ethile. Isibonelo, ukuguqulwa kungase kusetshenziswe ukubikezela izindleko zomkhiqizo noma isevisi, kunikezwe ezinye iziguquko.
Ukuhlukunyezwa kusetshenziselwa izimboni eziningi zokuhlela ibhizinisi nokukhangisa, ukubikezela kwezezimali, ukulinganisa imvelo nokuhlaziywa kwemikhuba.
Ukuhlukumeza Vs. Ukuhlukaniswa
Ukuhlukumeza nokuhlelwa kwezinhlelo kuyizindlela zokumbiwa kwedatha ezisetshenziselwa ukuxazulula izinkinga ezifanayo, kodwa zivame ukudideka. Zombili zisetshenziselwa ukuhlaziywa kokubikezela, kodwa ukuguqulwa kusetshenziselwa ukubikezela inani lenani eliqhubekayo noma eliqhubekayo ngenkathi ukuhlukanisa ukwabela idatha ngezigaba ezingafani.
Isibonelo, ukuguqulwa kuzosetshenziselwa ukubikezela inani lekhaya ngokususelwa endaweni yalo, izinyawo zesikwele, intengo lapho kuthengiswa ukugcina, intengo yemakhaya afanayo, nezinye izinto. Ukuhlukaniswa kuzoba kuhle uma ngabe ufuna ukuhlela izindlu zibe yizigaba, ezifana nokungahambi kahle, ubungako bezinhlamvu noma izinga lobugebengu.
Izinhlobo ZokuThuthukiswa Kwezindlela
Ifomu elilula futhi elidala kunazo zonke lokuhlukumeza ukuguqulwa okulinganiselwe okusetshenziselwa ukulinganisa ubuhlobo phakathi kokuguquguquka okubili. Le nqubo isebenzisa umthamo wezibalo womugqa oqondile (y = mx + b). Ngokucacile, lokhu kusho ukuthi, uma unikezwa igrafu nge-Y ne-X-axis, ubuhlobo phakathi kwe-X no-Y buyindlela eqondile nezingaphandle ezimbalwa. Isibonelo, singase sicabange ukuthi, uma kunikezwe ukwanda kwabantu, ukukhiqizwa kokudla kuzokwanda ngesilinganiso esifanayo - lokhu kudinga ubudlelwane obuqinile, obuhambisana phakathi kwezibalo ezimbili. Ukubona ngeso lengqondo lokhu, cabanga igrafu lapho i-Y-axis ilandelela khona inani labantu, futhi i-X-axis ilandelela ukukhiqizwa kokudla. Njengoba inani le-Y landa, inani le-X liyokwanda ngesilinganiso esifanayo, okwenza ubuhlobo phakathi kwabo luqonde.
Amasu okuthuthuka, njengokunciphisa okuningi, ukubikezela ubuhlobo phakathi kwezinguquko eziningi - isibonelo, ingabe kukhona ukulungiswa phakathi kweholo, imfundo nokuthi ubani okhetha ukuhlala? Ukwengezwa kwezinguquko eziningi kakhulu kwandisa ubuyinkimbinkimbi bokubikezela. Kunezinhlobo eziningana zamasu okuguqulwa amaningi okubandakanya okujwayelekile, okungaqondakali, okwehlulekayo nokwesigaba, ngasinye nesicelo salo.
Kuleli qophelo, kubalulekile ukuqonda ukuthi yini esizama ukuyibikezela (ukuhluka okuxhomekile noma okubikezelwe ) kanye nedatha esiyisebenzisayo ukwenza ukubikezela (okuguquguqukayo okuzimele noma okuphambili ). Esikhathini sethu, sifuna ukubikezela indawo lapho umuntu ekhetha ukuhlala khona (inguquko echazwe ngaphambilini ) enikezwa ngemali engenayo kanye nemfundo (kokubili ukuguquguquka kokuhlelwa ).
- Ukuguqulwa okujwayelekile okujwayelekile kubheka konke okuguquguqukayo kokuhlelwa ngesikhathi esifanayo. Isibonelo 1) yikuphi ukuhlobana phakathi kwemali engenayo kanye nemfundo (ukubikezela) kanye nokukhetha komakhelwane (okubikezelwe); futhi 2) ukuthi yiliphi izinga ukuthi umuntu ngamunye ozihlolisayo ahlanganyele kulobo buhlobo?
- Ukuziphendulela okuningi ukuphendula umbuzo ohluke ngokuphelele. I-algorithm yokulungisa ngokuzenzekelayo izohlaziya ukuthi yiziphi izibikezelo ezisetshenziselwa ukubikezela ukukhetha komakhelwane - okusho ukuthi imodeli yesinyathelo esilandelayo ihlola umyalelo wokubaluleka kokuguquguquka kokuhlelela bese ukhetha i-subset efanele. Lolu hlobo lwenkinga yokuvuselela lisebenzisa "izinyathelo" zokuthuthukisa ukulingana kokulinganisa. Njengoba unikezwe lolu hlobo lokunciphisa, zonke izibikezelo zingase zingabonakali ngisho nokulingana kokugcina kokulawula.
- Ukulawulwa kwemigomo yokuzimela , njengendlela engafaniyo, kuyindlela yokulandelana, kodwa izinguquko zokuhlela zifakwe emodeli ku-oda echazwe ngaphambilini ngaphambili, okusho ukuthi i-algorithm ayinalo isethi esakhelwe ukulinganisa ekunqumeni umyalelo faka izibikezelo. Lokhu kusetshenziswe kaningi uma umuntu edala ukulinganisa ukulingana unolwazi lobuchwepheshe kwensimu.
- Ukuhlukumeza okuhlukumezayo nakho kufana ne-stepwise kodwa kuhlaziywa amasethi wezinguquko kunezinguquko ezihlukile.
