Kukho amanqaku amaninzi malunga nezakhono ezifunekayo ukuba ube ngusosayensi wedatha efanelekileyo okanye umhlalutyi wedatha, kodwa amanqaku ambalwa athetha ngezakhono ezifunekayo ukuze uphumelele-ingaba yinto ekhethekileyo yokuphononongwa komsebenzi, indumiso evela kubaphathi, ukunyuswa, okanye zonke ezi ngasentla. Namhlanje sinikezela kuwe ngezinto ezithi umbhali angathanda ukwabelana ngamava akhe njengososayensi wedatha kunye nomhlalutyi wedatha, kunye noko akufundileyo ukuze aphumelele.
Ndinethamsanqa: Ndinikwe isikhundla senzululwazi yedatha xa ndingenamava kwiSayensi yeDatha. Indlela endiwuphethe ngayo lo msebenzi libali elahlukileyo, kwaye ndifuna ukuthi bendinombono ongacacanga wokuba yintoni eyenziwa sisazinzulu sedatha ngaphambi kokuba ndithathe umsebenzi.
Ndaqeshwa ukuba ndisebenze kwimibhobho yedatha ngenxa yomsebenzi wam wangaphambili njengenjineli yedatha, apho ndaphuhlisa i-data mart ye-predictive analytics esetyenziswa liqela leenzululwazi zedatha.
Unyaka wam wokuqala njengososayensi wedatha wawubandakanya ukudala imibhobho yedatha ukuqeqesha iimodeli zokufunda ngomatshini kunye nokuzifaka kwimveliso. Ndagcina iphrofayili ephantsi kwaye andizange ndithathe inxaxheba kwiintlanganiso ezininzi kunye nabachaphazelekayo bezentengiso ababengabasebenzisi bokugqibela beemodeli.
Kunyaka wesibini womsebenzi wam kwinkampani, umphathi wedatha kunye nohlalutyo onoxanduva lokuthengisa ushiye. Ukusukela ngoko ukuya phambili, ndaba ngumdlali ophambili kwaye ndathatha inxaxheba esebenzayo ekuphuhliseni iimodeli kunye nokuxoxa ngexesha elibekiweyo leprojekthi.
Njengoko ndandinxibelelana nabachaphazelekayo, ndiye ndafumanisa ukuba iNzululwazi yeDatha yingcamango engacacanga abantu abayive ngayo kodwa abayiqondi ncam, ngakumbi kumanqanaba aphezulu olawulo.
Ndakhe iimodeli ezingaphezulu kwekhulu, kodwa isithathu sazo sisetyenzisiwe kuba bendingayazi indlela yokubonisa ixabiso labo, nangona iimodeli beziceliwe ngokuyintloko ngokuthengisa.
Omnye wamalungu eqela lam uchithe iinyanga ephuhlisa imodeli abaphathi abaphezulu bacinga ukuba iya kubonisa ixabiso leqela lesayensi yedatha. Ingcamango yayikukusasaza imodeli kulo lonke umbutho emva kokuba iphuhlisiwe kwaye ikhuthaze amaqela okuthengisa ukuba ayamkele.
Kwaba kukungaphumeleli ngokupheleleyo kuba akukho mntu wayeqonda ukuba yintoni imodeli yokufunda umatshini okanye unokuqonda ukubaluleka kokuwusebenzisa. Ngenxa yoko, iinyanga zachithwa kwinto ebingafunwa mntu.
Kwiimeko ezinjalo ndiye ndafunda izifundo ezithile, endiya kunika ngezantsi.
Izifundo Endizifundileyo Ukuze Ndibe YiNzululwazi Yeenkcukacha Eziyimpumelelo
1. Zibekele impumelelo ngokukhetha inkampani efanelekileyo.
Xa udliwano-ndlebe kwinkampani, buza malunga nenkcubeko yedatha kunye nokuba zingaphi iimodeli zokufunda zoomatshini zamkelwe kwaye zisetyenziswe ekwenzeni izigqibo. Cela imizekelo. Fumana ukuba isiseko sakho sedatha simiselwe ukuqalisa ukwenza imodeli. Ukuba uchitha i-90% yexesha lakho uzama ukutsala idatha ekrwada kwaye uyicoce, uya kuba nexesha elincinane lokushiya nayiphi na imizekelo ukubonisa ixabiso lakho njengenzululwazi yedatha. Qaphela ukuba uqeshwe njengenzululwazi yedatha okokuqala. Oku kunokuba yinto enhle okanye embi, kuxhomekeke kwinkcubeko yedatha. Ungadibana nokuchasa ngakumbi ukuphumeza imodeli ukuba abaphathi abaphezulu baqesha iNzululwazi yeDatha kuba inkampani ifuna ukwaziwa njenge. usebenzisa iNzululwazi yeDatha ukwenza izigqibo ezingcono, kodwa andazi ukuba ithetha ukuthini kanye kanye. Ngaphezu koko, ukuba ufumana inkampani eqhutywa yidatha, uya kukhula nayo.
2. Yazi idatha kunye nezalathi zokusebenza eziphambili (KPIs).
Ekuqaleni, ndakhankanya ukuba njengenjineli yedatha, ndenze i-mart data yohlalutyo kwiqela leenzululwazi zedatha. Emva kokuba ndibe ngusosayensi wedatha ngokwam, ndiye ndakwazi ukufumana amathuba amatsha okwandisa ukuchaneka kweemodeli kuba ndisebenze ngokunyanisekileyo ngedatha ekrwada kwindima yam yangaphambili.
Ngokubonisa iziphumo zomnye wemikhankaso yethu, ndakwazi ukubonisa iimodeli ezivelisa amazinga aphezulu okuguqulwa (njengepesenti) kwaye emva koko ndalinganisa enye yephulo le-KPIs. Oku kubonise ixabiso lemodeli yokusebenza kweshishini apho ukuthengisa kunokunxulunyaniswa.
3. Qinisekisa ukwamkelwa komfuziselo ngokubonisa ixabiso lawo kubachaphazelekayo
Awusoze uphumelele njengenzululwazi yedatha ukuba abachaphazelekayo bakho abazange basebenzise iimodeli zakho ukwenza izigqibo zoshishino. Enye indlela yokuqinisekisa ukwamkelwa kwemodeli kukufumana indawo yentlungu yeshishini kwaye ubonise indlela imodeli enokunceda ngayo.
Emva kokuthetha neqela lethu lezentengiso, ndiye ndaqaphela ukuba abameli ababini basebenza ngokusisigxina bedibanisa izigidi zabasebenzisi kugcino lwedatha yenkampani ukuchonga abasebenzisi abanelayisensi enye ekunokwenzeka ukuba baphucule ukuya kwiilayisensi zeqela. Ukhetho lusebenzise isethi yemigaqo, kodwa ukhetho lwathatha ixesha elide kuba abameli bajonge umsebenzisi omnye ngexesha. Ndisebenzisa imodeli endiyiphuhliseyo, ii-reps zikwazile ukujolisa kubasebenzisi abanokuthi bathenge ilayisenisi yeqela kunye nokwandisa amathuba okuguqulwa ngexesha elincinci. Oku kubangele ukusetyenziswa ngokufanelekileyo kwexesha ngokunyusa izinga lokuguqulwa kwezalathisi eziphambili zokusebenza ezinokuhambelana neqela lentengiso.
Kwadlula iminyaka eliqela ndaza ndaphuhlisa iimodeli ezifanayo ngokuphindaphindiweyo kwaye ndaziva ngathi andisafundi kwanto intsha. Ndagqiba ekubeni ndikhangele esinye isikhundla kwaye ndagqiba ekubeni ndifumane isikhundla somhlalutyi wedatha. Umahluko kwiimfanelo zazingenakubaluleka ngakumbi xa kuthelekiswa naxa ndandiyinzululwazi yedatha, nangona ndandibuyela ukuxhasa ukuthengisa.
Eli yayilixesha lokuqala ndihlalutya imifuniselo ye-A/B ndaza ndayifumana zonke iindlela apho umfuniselo unokuhamba kakubi. Njengososayensi wedatha, andizange ndisebenze kuvavanyo lwe-A / B konke konke kuba ibigcinelwe iqela lovavanyo. Ndisebenze kuluhlu olubanzi lohlalutyo olunempembelelo yentengiso-ukusuka ekwandiseni amazinga oguqulo eprimiyamu ukuya kunxibelelwano lwabasebenzisi kunye nothintelo lwe-churn. Ndifunde iindlela ezininzi ezahlukeneyo zokujonga idatha kwaye ndichithe ixesha elininzi ndiqulunqa iziphumo kwaye ndibonise abachaphazelekayo kunye nabaphathi abaphezulu. Njengososayensi wedatha, bendisebenza kakhulu kuhlobo olunye lwemodeli kwaye andifane ndinike iintetho. Ukukhawuleza kwiminyaka embalwa kwizakhono endizifundileyo ukuba ndibe ngumhlalutyi ophumelelayo.
Izakhono Endizifundileyo Zokuba nguMhlalutyi weDatha oPhumelelayo
