Uxilongo luhlalutya ubudlelwane phakathi kweenguqu
Ukunyanzeliswa yindlela yokuchithwa kwedatha esetyenzisiweyo ukuchaza ubungakanani bexabiso leenombolo (elibizwa ngokuba lixabiso eliqhubekayo ), linikezelwe i datasethi ethile. Ngokomzekelo, ukuguqulwa kungasetyenziselwa ukuqikelela iindleko zemveliso okanye inkonzo, enikwe ezinye iinguqulelo.
Ukunyanzeliswa kusetyenziswa kuwo onke amashishini amaninzi ekucwangciseni ishishini kunye nokuthengisa, ukubikezela ngemali, ukulungiswa kwemvelo kunye nokuhlaziywa kwemikhwa.
Uxinzelelo lweVs. Ukwahlula
Ukunyanzeliswa nokuhlengahlengiswa kukusetyenziswa kweendlela zokumbiwa kwedatha ezisetyenziselwa ukusombulula iingxaki ezifanayo, kodwa zihlala zididekile. Zomibini zisetyenziselwa ukuhlaziywa kwangaphambili, kodwa ukuguqulwa kusetyenziselwa ukuqikelela inani eliqhubekayo okanye eliqhubekayo ngelixa udidi lukwabela idatha kwiindidi ezichaziweyo.
Ngokomzekelo, ukuguqulwa kuya kusetyenziswa ukuqikelela ixabiso lekhaya elisekelwe kwindawo yalo, iinyawo zendawo, ixabiso xa kuthengiswa okokugqibela, intengo yamakhaya afanayo kunye nezinye izinto. Ukwahlula kwakuya kuba ufuna ukuba kunoko uhlele izindlu zibe ngamacandelo, njengokubheka, ubungakanani bexabiso okanye ulwaphulo-mthetho.
Iintlobo zeTranscription Techniques
Ifom elula kunye neyadala yokuguqulwa komzimba kusetshenziselwa ukuqikelela ubudlelwane phakathi kweenguqu ezimbini. Le ndlela isebenzisa umgaqo wemathematika wendlela eqondekileyo (y = mx + b). Ngokucacileyo, oku kuthetha ukuba, unike igrafu ene-Y kunye ne-X-axis, ubudlelwane phakathi kwe-X no-Y ngumgca ochanekileyo kunye neembalwa ezimbalwa. Ngokomzekelo, sinokucinga ukuba, xa kunike ukwanda kwabemi, ukuveliswa kokutya kuza kwanda ngezinga elifanayo - oku kufuna ukuba ubudlelwane obuqinileyo, obuqinileyo phakathi kwamanani amabini. Ukujonga ngolu hlobo, cinga igrafu apho u-Y-axis ulandelela ukwanda kwebemi, kunye ne-X-axis ilandelela ukuveliswa kokutya. Njengoko ixabiso leY liyanda, ixabiso leX liza kunyuka ngezinga elifanayo, okwenza ubudlelwane phakathi kwabo baqonde ngqo.
Amasu aphakamileyo, afana nokuguqulwa kwamanani amaninzi, uqikelele ubudlelwane phakathi kwezinto eziguquguqukayo ezininzi - umzekelo, ngaba kukho ukulungiswa phakathi kwemali engenayo, imfundo kwaye apho umntu ekhetha ukuhlala? Ukongezwa kweenguqu ezininzi kukhulisa kakhulu ubunzima bokuchazwa. Kukho iintlobo ezininzi zeendlela zokuguqulwa ezininzi ezibandakanya umgangatho oqhelekileyo, ulungelelaniso, ulungelelaniso kwaye uhambelane, ngasinye nesicelo sakho.
Kule nto, kubalulekile ukuqonda oko sikuzama ukukulinganisa (ukuxhomekeka okanye okuchaziweyo ) kunye nedatha esisisebenzisayo ukwenza ukubikezelwa (izixhobo ezizimeleyo okanye izilungelelaniso ). Ngokomzekelo wethu, sifuna ukuqikelela indawo apho umntu ekhetha ukuhlala (intsingiselo echazwe ngaphambili ) enikezwa ngeniso nemfundo (zombini ukuguquguquka kwezinto).
- Ukuguqulwa kwamanani amaninzi kukujonga zonke iinguqu zokuguquguquka ngexesha elifanayo. Umzekelo 1) luphi ulwalamano phakathi kwemali engenayo kunye nemfundo (i-predictors) kunye nokukhethwa komakhelwane (kuqikelelwe); kunye no-2
- Ukuhamba ngokuphindaphindiweyo ukuphendula ngokuphindaphindiweyo ukuphendula umbuzo ohluke ngokupheleleyo. I-algorithm yokulawula i-stepwise iya kuhlalutya ukuba zeziphi iingqiqo ezisetyenziselwa ukuxela ukukhethwa kwendawo yokuhlala-oko kuthetha ukuba imodeli ehamba ngokukhawuleza ihlola umyalelo wokubaluleka kweenguqu zokuzikhethela kwaye ukhetha i-subset echaphazelekayo. Olu hlobo lweengxaki zokulawula ukusetyenziswa lusebenzisa "amanyathelo" ekuphuhliseni i-equation equation. Njengoko lolu hlobo lokuguqulwa, zonke izibhengezo zingabonakali nakwi-equation regression equation.
- Ukulawulwa kwamathambo , njengendlela ehambelanayo, yinkqubo elandelelanayo, kodwa iinguqu zengqungquthela zingena kumzekelo kwindlela echazwe ngaphambili ekhankanywe kwangaphambili, oko kukuthi i-algorithm ayinayo i-equation set of equations yokumisela umyalelo apho ukungena kwiingqungquthela. Oku kusetyenziswa rhoqo xa umntu edala i-equation equation ine-expert expert field.
- Ukuguqulwa kweendlela eziqhelekileyo kufana nokufana nesinyathelo kodwa uhlalutya iiseti zezinto eziguquguqukileyo kunokuba ziguquke.
