Dziwani za Art of Exploratory Data Analysis
M'dziko limene deta yakhala mafuta atsopano, kudziwa momwe mungasankhire ndi luso lofunikira. Maphunziro a "Perform Exploratory Data Analysis" operekedwa ndi OpenClassrooms ndi njira yabwino kwa aliyense amene akufuna kudziwa lusoli. Ndi nthawi ya maola 15, maphunziro apakati awa adzakuthandizani kumvetsetsa momwe deta yanu ikuchitikira chifukwa cha njira zamphamvu monga Principal Component Analysis (PCA) ndi k-njira masango.
Pamaphunzirowa, muphunzira momwe mungapangire kusanthula kwamitundu yambiri, chida chofunikira kwa aliyense wabwino wa Data Analyst. Mudzatsogoleredwa pakugwiritsa ntchito njira zodziwika kuti mufufuze mwamsanga chitsanzo chanu, kuchepetsa kuchuluka kwa chiwerengero cha anthu kapena zosiyana. Njira zodziwika bwino monga PCA zimakulolani kuti muzindikire mwamsanga zochitika zazikulu mu chitsanzo chanu, mwa kuchepetsa chiwerengero cha zosinthika zofunikira kuti muyimire deta yanu, ndikutaya chidziwitso chochepa momwe mungathere.
Zofunikira pamaphunzirowa ndi luso la masamu pa Terminale ES kapena S level, kudziwa bwino ziwerengero zofotokozera za mbali imodzi ndi ziwiri, komanso luso la Python kapena R chinenero cha Data Science. Lamulo labwino la malaibulale a pandas, NumPy ndi Matplotlib lidzakhala lofunikira ngati mutasankha Python ngati chilankhulo chanu.
Lowani mu Maphunziro Olemera ndi Okhazikika
Kuyamba kusanthula deta kumafuna maphunziro okonzedwa bwino. OpenClassrooms imakupatsirani njira yophunzirira yomwe ilingaliridwa bwino yomwe imakuwongolerani pamagawo osiyanasiyana ophunzirira. Mudzayamba ndi mawu oyambira pakuwunika kwamitundu yambiri, komwe mupeza chidwi cha njirayi ndikukumana ndi akatswiri pantchitoyi, monga Emeric Nicolas, wasayansi wodziwika bwino wa data.
Pamene mukupita patsogolo mu maphunzirowa, mudzadziwitsidwa ku malingaliro apamwamba kwambiri. Gawo lachiwiri la maphunzirowa lidzakumitsirani kudziko la Principal Component Analysis (PCA), njira yomwe ingakuthandizeni kumvetsetsa zovuta ndi njira zochepetsera miyeso. Muphunziranso momwe mungatanthauzire bwalo lamalumikizidwe ndikusankha kuchuluka kwa zigawo zomwe mungagwiritse ntchito pakuwunika kwanu.
Koma si zokhazo, gawo lachitatu la maphunzirowa lidzakudziwitsani za njira zogawanitsa deta. Muphunzira za algorithm ya k-njira, njira yodziwika bwino yogawa deta yanu m'magulu amodzi, komanso njira zophatikizira zotsogola. Maluso awa ndi ofunikira kwa wosanthula deta aliyense yemwe akufuna kuchotsa zidziwitso zamtengo wapatali kuchokera kuzinthu zambiri.
Maphunzirowa ndi athunthu ndipo amakupatsani zida zomwe mukufunikira kuti mukhale katswiri pakusanthula deta. Mudzatha kusanthula deta yowunikira paokha komanso moyenera, luso lofunidwa kwambiri masiku ano akatswiri.
Wonjezerani Professional Horizons ndi Pragmatic Training
M'munda wosinthika wa sayansi ya data, kupeza maluso othandiza ndikofunikira. Maphunzirowa amakukonzekeretsani kulimbana ndi mavuto enieni amene mudzakumane nawo m’ntchito yanu yamtsogolo. Mukadzipereka nokha muzophunzira zenizeni ndi mapulojekiti othandiza, mudzakhala ndi mwayi wogwiritsa ntchito chidziwitso chomwe mwapeza.
Chimodzi mwazabwino zazikulu zamaphunzirowa ndikupeza gulu la ophunzira omwe ali ndi malingaliro ofanana ndi akatswiri. Mudzatha kusinthanitsa malingaliro, kukambirana mfundo komanso kugwirizanitsa ntchito, ndikupanga maukonde ofunika pantchito yanu yamtsogolo. Kuphatikiza apo, nsanja ya OpenClassrooms imakupatsirani kuyang'anira kwanu, kukulolani kuti mupite patsogolo pa liwiro lanu pomwe mukupindula ndi thandizo la akatswiri pantchitoyo.
Kuphatikiza apo, maphunzirowa amakupatsirani kusinthasintha kosayerekezeka, kukulolani kuti muzitsatira maphunzirowo pamayendedwe anuanu, kuchokera pakutonthoza kwanu. Njira yophunzirira yokhayokhayi si yothandiza chabe, komanso imalimbikitsa chitukuko cha kudziletsa ndi luso loyendetsa nthawi, zinthu zamtengo wapatali m'dziko lamakono lamakono.
Mwachidule, maphunzirowa ndi njira yopezera ntchito yopambana pazasayansi ya data. Sikuti amakupatsirani luso lolimba laukadaulo, komanso chidziwitso chothandiza chomwe chidzakusiyanitsani pamsika wantchito.
