Pitani patsogolo mu sayansi ya deta mwa kuphunzira imodzi ya zilankhulo zopindulitsa
Izi ndizomwe asayansi amachitira: kupeza zinthu, kudziyanjanitsa, kupanga ma data, ndi makampani othandiza ogwira ntchito bwino.
Ndipo kumvetsetsa bwino zilankhulo zoyenerera ndizofunikira pakumasulira ziwerengero ndikugwira ntchito ndi zidziwitso.
Malingana ndi KDnuggets, 91% asayansi a deta amagwiritsa ntchito zinenero zinayi zotsatirazi.
Chilankhulo 1: R
R ndi chiwerengero chodziwika bwino pakati pa olemba deta. Ndiwotseguka, wogwiritsa ntchito moyenera, S, ndipo sichivuta kwambiri kuphunzira.
Ngati mukufuna kudziwa momwe mungakhalire mapulogalamu, R ndi chinenero chabwino kuti mudziwe. Ikuthandizani kuti muzigwiritsa ntchito komanso kusonyeza deta.
Monga mbali ya pulogalamu yawo ya Science Science Specialization, Coursera amapereka kalasi pa R zomwe sizikuphunzitsani momwe mungayankhire m'chinenerocho komanso zimapitilira momwe mungagwiritsire ntchito pa nkhani ya sayansi / kusanthula deta.
Chilankhulo 2: SAS
Mofanana ndi R, SAS imagwiritsidwa ntchito makamaka pakuwerengetsa ziwerengero. Ndi chida champhamvu chosinthira deta kuchokera m'mabuku ndi masamba pamasewero omwe angawoneke (monga HTML ndi malemba a PDF) komanso matebulo owonetserako komanso ma grafu.
Poyambirira ndi akatswiri ofufuza maphunziro, wakhala akugwiritsidwa ntchito kwambiri padziko lonse kwa makampani ndi mabungwe a mitundu yonse. Zambiri mwa mapulogalamu akuluakulu a makampani ndipo sagwiritsidwa ntchito ndi makampani ang'onoang'ono kapena anthu omwe akugwira ntchito pawokha.
Zida zothandizira SAS zili mu ndondomekoyi .
Chilankhulo sichingachoke, kotero mwinamwake simungathe kudziphunzitsa nokha kwaulere.
Chilankhulo 3: Python
Ngakhale kuti R ndi SAS amakonda kuganiza kuti ndi "zazikulu" mu dziko la analytics, Python yakhala yotsutsana kwambiri posakhalitsa. Chimodzi mwa zida zake zazikulu ndi ma library osiyanasiyana (mwachitsanzo, Pandas, NumPy, SciPi, etc.) ndi zowerengetsera ntchito.
Popeza Python (monga R) ndi chinenero choyera, zosinthidwa zikuwonjezeredwa mwamsanga. (Ndi mapulogalamu ogula ngati SAS, muyenera kuyembekezera kumasulidwa kotulutsidwa.)
Chinthu china choyenera kulingalira ndi chakuti Python ndi yophweka kwambiri kuphunzira, chifukwa cha kuphweka kwake komanso kupezeka kwa maphunziro ndi zinthu zomwe zilipo. Webusaitiyi ndi malo abwino kuyamba.
Mukhozanso kupeza mndandanda wa zida zophunzirira Python pano.
Chilankhulo 4: SQL
Mpaka pano takhala tikuyang'ana pa zilankhulo zomwe zili m'banja limodzi ndipo (zambiri kapena zochepa) ziri ndi ntchito zomwezo. SQL, yomwe imayimira "Language Query Query," ndi pamene kusintha. Chilankhulochi sichinafanane ndi ziwerengero; limakhudza momwe mungagwiritsire ntchito chidziwitso m'mabuku ochezera.
Ndilo mawu ogwiritsidwa ntchito kwambiri kuposa onse omwe amapezeka m'mabuku a deta ndipo ali otseguka, kotero kuti akatswiri a deta asakayikire kuti sayenera kulumphira.
Kuphunzira SQL kukuyenera kukukonzerani kuti mupange SQL zolinga, kuyendetsa deta mkati mwawo, ndikugwiritsa ntchito ntchito yoyenera. Udemy imaphunzitsa maphunziro omwe akuphatikiza zofunikira zonse ndipo akhoza kutsirizidwa mofulumira komanso mopweteka.
Kutsiliza
Pang'ono ndi pang'ono, muyenera kuphunzira SQL ndi kusankha chimodzi mwa ziwerengero za ziwerengero. Koma ngati muli ndi nthawi (komanso pa nkhani ya SAS, ndalama) ndipo mukufuna kuti mukhale ogulitsa, palibe chomwe munganene kuti simungathe kuphunzira zonse zinayi!
Musathamangire, muzichita zambiri, yesani luso lanu-ndipo muzisangalala ndi ntchito.
