Feem coob ntawm cov neeg pov npav hauv tseeb KDnuggets Poll cia siab tias tus kws tshaj lij qib Data Science yuav tsum automated hauv 10 xyoo lossis tsawg dua. Los ntawm Gregory Piatetsky, KDnuggets. Data Scientist tau raug hu ua txoj haujlwm sexiest ntawm lub xyoo pua 21st. Tab sis tej zaum lub xyoo pua yuav kav tsuas yog 25 xyoo.
Yog li ntawd, cov ntaub ntawv cov kws tshawb fawb puas yuav dhau los lawm?
Cov ntaub ntawv kws tshawb fawb yuav dhau los lawm nyob rau hauv lub neej yav tom ntej nrog lub nce nyob rau hauv Data Science ? Thaum lub luag hauj lwm ntawm lub cov kws tshawb fawb cov ntaub ntawv tau pov npav los ua ib txoj haujlwm zoo tshaj plaws hauv 2016, nws tau kwv yees tias hauv Asmeskas ib leeg, muaj yuav ua ib tug mob tsis txaus cov kws tshawb fawb cov ntaub ntawv mus txog 1,40,000 rau 1,90,000 los ntawm 2018.
Kuj Paub, yog Data Science nyob ntawm no? Data Science yog nyob ntawm no ntev, ntev. Yog li, yog, nws yog 'kev nyab xeeb' txoj haujlwm los mus nrhiav.

Txhua yam ntawm lub vev xaib, huab, txawb, SaaS (software ua kev pabcuam), thiab loj cov ntaub ntawv.
Hais txog qhov no, cov ntaub ntawv science yog yav tom ntej?
Vim li cas Data Science yog Txoj Haujlwm ntawm Lub Yav tom ntej . Lub luag haujlwm ntawm tus kws tshawb fawb cov ntaub ntawv tam sim no yog ib txoj hauj lwm buzzworthy. Nws muaj lub zog nyob hauv kev ua lag luam thiab muab sijhawm rau cov neeg kawm cov ntaub ntawv science ua kom muaj txiaj ntsig zoo rau lawv cov tuam txhab thiab cov koom haum loj.
Puas yog tus kws tshawb fawb cov ntaub ntawv ua haujlwm zoo?
A Data Scientist , raws li Harvard Kev Tshawb Fawb Kev Lag Luam, yog tus kws tshaj lij qib siab nrog kev cob qhia thiab kev xav paub los ua kom pom nyob hauv lub ntiaj teb ntawm Loj. Cov ntaub ntawv ”. Yog li ntawd nws los li tsis muaj surprise tias Cov kws tshawb fawb Data yog coveted cov kws tshaj lij nyob rau hauv Loj Cov ntaub ntawv Analytics thiab IT kev lag luam.
