Tsvaga iyo Art yeExploratory Data Analysis
Munyika umo data rave mafuta matsva, kuziva nzira yekuiongorora hunyanzvi hwakakosha. Iyo "Perform Exploratory Data Analysis" kudzidziswa kunopihwa neOpenClassrooms ndeye godsend kune chero munhu ari kutsvaga kugona iyi art. Nenguva yemaawa gumi nemashanu, iyi yepakati nhanho kosi ichakubvumidza iwe kuti unzwisise mafambiro edataset yako nekuda kwenzira dzine simba dzakadai sePrincipal Component Analysis (PCA) uye k-zvinoreva kubatanidza.
Munguva yekudzidziswa uku, iwe uchadzidza maitiro ekuita multidimensional yekuongorora ongororo, chishandiso chakakosha kune chero yakanaka Data Analyst. Iwe unozotungamirwa mukushandiswa kwemaitiro akakurumbira kukurumidza kuongorora sampu yako, kuderedza chiyero chenhamba yevanhu kana zvakasiyana. Iconic nzira dzakadai sePCA dzinokubvumira kukurumidza kuziva maitiro makuru mumuenzaniso wako, nekuderedza nhamba yezvinyorwa zvakakosha kuti umiririre data yako, uchirasikirwa neruzivo ruduku sezvinobvira.
Izvo zvinodikanwa zvekosi iyi kugona kwemasvomhu paTerminale ES kana S level, ruzivo rwakanaka rwemwe-dimensional uye maviri-dimensional anotsanangura manhamba, pamwe nekugona kwePython kana R mutauro mumamiriro eData Sayenzi. Murairo wakanaka wepapandas, NumPy uye Matplotlib maraibhurari ichave yakakosha kana ukasarudza Python semutauro wako wechirongwa.
Dzvanya mune Yakapfuma uye Yakarongwa Dzidzo
Kutanga mukuongorora data data kunoda kudzidziswa kwakarongeka uye kwakarongeka. OpenClassrooms inokupa iwe yakanyatsofungwa-yedzidzo nzira inokutungamira mumatanho akasiyana ekudzidza. Iwe unozotanga nechisumo chekuongorora kwakasiyana-siyana kuongororwa, kwaunowana kufarira kweiyi nzira uye kusangana nenyanzvi mumunda, dzakadai saEmeric Nicolas, ane mukurumbira data sainzi.
Sezvo iwe uchifambira mberi kuburikidza nekudzidziswa, iwe unozoziviswa kune mamwe epamusoro pfungwa. Chikamu chechipiri chekosi chinokunyudza iwe munyika yePrincipal Component Analysis (PCA), hunyanzvi hunokubvumidza kuti unzwisise nyaya uye nzira dzekudzikisa chiyero. Iwe unozodzidzawo kududzira denderedzwa rekubatanidza uye sarudza huwandu hwezvikamu zvekushandisa mukuongorora kwako.
Asi handizvo zvese, chikamu chechitatu chekosi chinokuzivisa iwe kumatekiniki ekugovera data. Iwe unozodzidza nezve k-zvinoreva algorithm, yakakurumbira nzira yekuisa data rako mumapoka ane homogeneous, pamwe ne hierarchical clustering matekiniki. Unyanzvi uhwu hwakakosha kune chero muongorori wedata anotarisa kuti atore nzwisiso yakakosha kubva kune yakakura mavhoriyamu data.
Iyi dzidziso yakazara uye inokupa iwe maturusi aunoda kuti uve nyanzvi yekuongorora data. Iwe unozogona kuita yekuongorora data yekuongorora wakazvimirira uye nemazvo, hunyanzvi hunotsvakwa zvakanyanya munyika yanhasi yehunyanzvi.
Wedzera yako Professional Horizons nePragmatic Training
Mundima ine simba yesainzi yedata, kuwanikwa kwehunyanzvi hunoshanda kwakakosha. Kudzidziswa uku kunokugadzirira kuti usangane nematambudziko chaiwo auchasangana nawo mubasa rako remangwana. Nekunyura iwe pachako muzvidzidzo zvezviitiko uye mapurojekiti anoshanda, iwe uchave nemukana wekushandisa ruzivo rwetioretical rwakawanikwa.
Imwe yemabhenefiti makuru ekudzidziswa uku kuwana nharaunda yevadzidzi vane pfungwa dzakafanana uye nyanzvi. Iwe unozogona kuchinjana mazano, kukurukura pfungwa uye kunyange kubatana pamapurojekiti, kugadzira network yakakosha yebasa rako remangwana. Uye zvakare, iyo OpenClassrooms chikuva inokupa iwe yakasarudzika yekutarisa, ichikubvumidza kuti ufambire mberi nekumhanya kwako uchibatsirwa nerubatsiro rwenyanzvi mumunda.
Uye zvakare, iyi dzidziso inokupa iwe isingaenzaniswi kuchinjika, ichikutendera iwe kuti uteedzere makosi nekumhanya kwako, kubva mukunyaradza kweimba yako. Iyi nzira yekudzidza yega yega haisi kungoshanda chete, asiwo inokurudzira kukura kwekuzvibata uye unyanzvi hwekugadzirisa nguva, zvinhu zvinokosha munyika yanhasi yeunyanzvi.
Muchidimbu, kudzidziswa uku igedhi rebasa rakabudirira mumunda wesainzi yedata. Izvo hazvingokushongedza iwe nehunyanzvi hwakasimba hwetioretical, asiwo ruzivo runoshanda runokumisa iwe pamusika webasa.
