- Ososayensi bedatha basebenzisa izibalo nezibalo ukuze bathuthukise ukwenza izinqumo zebhizinisi.
- Indima yakhe ihlanganisa ukusebenzisa amathuluzi afana ne-Hadoop ukucubungula imiqulu emikhulu yedatha.
- Basebenza ngokukhethekile emisebenzini ehlukahlukene, kusukela ekuhlaziyweni kwedatha kuya ekuhleleni nasekuboneni ngeso lengqondo.
- Amakhono okuxhumana ayisihluthulelo sokuhumusha okutholwe yizobuchwepheshe kuzithameli ezingezona ezobuchwepheshe.
Usosayensi Wedatha: Izindima Nezibopho
Uyini usosayensi wedatha?
Usosayensi wedatha uchwepheshe onguchwepheshe wokuhlaziya idatha, ukumbiwa kwedatha, nokufunda ngomshini. Basebenzisa ukufunda komshini ukuze benze amamodeli aqagelayo ukuze amabhizinisi abo akhule ngokushesha, ngempumelelo, nangenzuzo enkulu.
Ososayensi bedatha bavame ukuqashwa amabhizinisi noma izinkampani zobuchwepheshe. Indima yososayensi wedatha iyahlukahluka kuye ngemboni; noma kunjalo, ngokuvamile ihilela ukusebenzisa amathuluzi afana ne-Hadoop ukucubungula ngokushesha inani elikhulu lolwazi ( idatha enkulu ).
Njengososayensi wedatha, uzosebenzisa amakhono akho ukuze uhlaziye amasethi edatha amakhulu nayinkimbinkimbi. Uzokhipha ulwazi kudatha futhi wenze izibikezelo ngokusekelwe kulokho okutholile. Umsebenzi wakho ungase futhi uhlanganise ukudala amamodeli nama-algorithms asiza izinkampani zenze izinqumo ezingcono zisebenzisa ulwazi eziluqoqayo.
Iqhaza likasosayensi wedatha lisha futhi alikachazwa kahle.
Kunezinhlobo eziningi ezahlukene zososayensi bedatha, abanamazinga ahlukahlukene omthwalo wemfanelo negunya. Umhlaziyi wezinga elincane angase abe nesibopho sokuqoqa futhi ahlele idatha evela emithonjeni ehlukahlukene, kuyilapho umhlaziyi wezinga lochwepheshe angase abe negunya elibalulekile lokuthatha izinqumo ngaphakathi komnyango we-IT wenhlangano noma iyunithi yebhizinisi.
Ososayensi bedatha bavame ukuqashwa amabhizinisi noma izinkampani zobuchwepheshe.
Uma ungathanda ukuba usosayensi wedatha, kungenzeka ukuthi uyazibuza ukuthi ungawutholaphi umsebenzi. Ososayensi bedatha bavame ukuqashwa amabhizinisi noma izinkampani zobuchwepheshe ezinezinkinga ezinkulu zedatha. Basebenzisana nonjiniyela bedatha ukuze baxazulule lezi zinkinga, ezingahlanganisa noma yini kusukela ekuthuthukiseni ukwaneliseka kwamakhasimende kuya ekubikezeleni ukuthi abantu bafuna ini ngaphambi kokuthi bazi nokuthi bayakufuna.
Kwesinye isikhathi inkampani iqasha usosayensi wedatha ngoba ifuna umuntu oyiqonda kangcono inkinga yakhe kunanoma ngubani oseqenjini layo, futhi ngezinye izikhathi ngoba umxhumanisi ubatshele ukuthi uyayidinga.
Kungakhathaliseki ukuthi yisiphi isizathu sakho sokuqasha isisebenzi esisha (noma ezimbili), kunamathuba amaningi atholakalayo kulabo abawafunayo. Imisebenzi yesayensi yedatha ayigcini nje ngokunikeza inkokhelo enhle kakhulu, kodwa futhi ivumela ukuguquguquka kwendawo namahora, inqobo nje uma kukhona ukufinyelela kwe-inthanethi eduze.
Ukufunda komshini
Basebenzisa ukufunda komshini ukuze benze amamodeli abikezelayo ukuze amabhizinisi abo akhule ngokushesha, ngempumelelo nangenzuzo enkulu.
Ukufunda ngomshini kuyisayensi yokwenza amakhompyutha asebenze ngaphandle kokuhlelwa okucacile. Isetshenziselwa ukudala amamodeli abikezelayo avumela izinkampani ukuthi zikhule ngokushesha, ngokuphumelelayo nangenzuzo enkulu.
Ingasetshenziselwa ukuthola amaphethini kumasethi amakhulu wedatha (isibonelo, ngokubheka ukuziphatha kwamakhasimende esikhathi esidlule) ukuze izinkampani zenze izinqumo ezingcono mayelana nemikhankaso yokumaketha yesikhathi esizayo noma izinqubo zokukhiqiza.
Wenzani usosayensi wedatha?
Kunezinhlobonhlobo eziningi kulokho okwenziwa usosayensi wedatha. Bangasebenza ngokukhethekile emikhakheni ehlukene, ubuchwepheshe kanye nezinhlobo zedatha. Futhi zisebenza ngokukhethekile emisebenzini ehlukene: isibonelo, ezinye zigxila ekudaleni amamodeli, kuyilapho ezinye zigxila ekukhipheni ulwazi kulawo mamodeli. Abanye basebenza ngaphambili futhi abanye basebenza ngemuva, ngakho-ke kunezindlela eziningi zokuba usosayensi wedatha ngaphandle kokuba uchwepheshe kukho konke.
Imisebenzi yososayensi wedatha
Izindima nezibopho zikasosayensi wedatha zimi kanje:
Ukuhlaziywa kwedatha
Usosayensi wedatha kufanele abe namakhono okuhlaziya aqinile ukuze abone amaphethini, amathrendi, nemininingwane efanele evela kumasethi amakhulu edatha.
Ukuhlela kanye Nobunjiniyela Bedatha
Kumele abe namakhono okuhlela nolwazi kubunjiniyela bedatha. Amakhono okuhlela asiza ukwakha nokushuna amamodeli okufunda omshini, kuyilapho amakhono obunjiniyela bedatha esiza ukuphatha nokuhlanza idatha.
Ulwazi lwezibalo
Usosayensi wedatha udinga ulwazi oluqinile ngezibalo ukuze adale futhi ahumushe amamodeli ezibalo. Lokhu kubalulekile, njengoba izibalo zinikeza isisekelo sokuqonda iziguquguquko nokuthola iziphetho kusuka kudatha ehlaziyiwe.
ukubonwa kwedatha
Kufanele ube nekhono lokuxhumana ngokutholwe kwedatha ngokuphumelelayo usebenzisa amathuluzi abonakalayo. Leli khono lisiza ababambiqhaza baqonde ubudlelwano phakathi kokuguquguqukayo, amathrendi, namaphethini kumasethi wedatha.
Ulwazi lwebhizinisi
Udinga ukuba nolwazi lwesizinda sebhizinisi ukuze uqonde inkinga abazama ukuyixazulula ngedatha. Ulwazi lwebhizinisi futhi lusiza usosayensi wedatha ukuthi abeke phambili amaphrojekthi ngokusekelwe kumthelela wabo webhizinisi.
Amakhono wokuxhumana
Njengososayensi wedatha, kufanele ukwazi ukuchaza imiqondo yezobuchwepheshe kubantu okungebona abezobuchwepheshe abazohlomula kokutholakele. Ukuxhumana ngokusobala okutholwe ngobuchwepheshe nababambiqhaza abangebona abezobuchwepheshe kusiza ukwakha ukwethenjwa endleleni eqhutshwa idatha futhi kusebenza njengesisusa soguquko.
Lezi ezinye zezindima ezivame kakhulu nezibopho zikasosayensi wedatha, kodwa izibopho zangempela zingahluka ngokwenhlangano, inkambu, namakhono obuchwepheshe.
Isiphetho
Sengiphetha, indima kasosayensi wedatha idinga isethi ehlukile yamakhono nolwazi. Umuntu okulesi sikhundla kufanele akwazi ukucabanga ngobuciko ngendlela idatha engasetshenziswa ngayo ngezinjongo zebhizinisi futhi enze izibikezelo mayelana nokuzokwenzeka esikhathini esizayo ngokusekelwe ezenzakalweni ezedlule.
