Iwe unogona kunge wakambonzwa nezvevanoongorora, kudzidza muchina uye nyanzvi dzehungwaru hwekunyepedzera, asi wakambonzwa nezveavo vanobhadharwa zvisina kunaka? Meet data charlatan! Aya ma hacks, anokwezvwa nemabasa ane mari, anopa chaiyo data masayendisiti zita rakaipa. Muzvinyorwa tinonzwisisa nzira yekuunza vanhu vakadai kumvura yakachena.
Data charlatans vari kwese kwese
Data charlatans akanaka kwazvo pakuvanda pachena zvekuti unogona iva mumwe wavondisingatombozvizivi. Mikana iripo, sangano rako ranga rakachengeta vakomana vanonyengerera kwemakore, asi nhau dzakanaka ndedzekuti vari nyore kuziva kana iwe uchiziva zvekutarisa.
Chiratidzo chekutanga chekunyevera kusanzwisisa izvozvo analytics uye manhamba maitiro akasiyana kwazvo. Ndichatsanangura izvi zvakare.
Zvirango zvakasiyana
Statisticians vakadzidziswa kutora mhedziso pamusoro pezvinoenda kupfuura data ravo, vaongorori vanodzidziswa kuongorora zviri mukati me data set. Mune mamwe mazwi, vaongorori vanotora mhedziso pamusoro pezviri mudhata ravo, uye vanoongorora vanotora mhedziso nezve izvo zvisiri mu data. Vaongorori vanokubatsira kubvunza mibvunzo yakanaka (ita fungidziro), uye vezvenhamba vanokubatsira kuwana mhinduro dzakanaka (yedza zvaunofungidzira).
Kunewo mabasa akasanganiswa asinganzwisisiki apo munhu anoedza kugara pazvigaro zviviri ... Sei? Nheyo yekutanga yesainzi yedata: kana uri kubata nekusagadzikana, haugone kushandisa zvimwe chete data point ye hypotheses uye kuyedza. Kana data iri shoma, kusava nechokwadi kunomanikidza sarudzo pakati pehuwandu kana analytics. Tsananguro .
Pasina manhamba, unenge wakamira uye usingakwanise kunzwisisa kana mutongo wauchangobva kugadzira wakamira, uye pasina ongororo, uri kufamba neupofu, uine mukana mudiki wekudzora zvisingazivikanwe. Iyi isarudzo yakaoma.
Nzira yaCharlatan yekubuda munyonganyonga iyi ndeyekuifuratira obva anyepedzera kushamisika nezvinongoerekana zvamuka. Iyo pfungwa yekuseri kwekuyedza manhamba ekufungidzira inouya pasi kumubvunzo wekuti iyo data inotishamisa zvakakwana kuti tichinje pfungwa dzedu. Tinogona sei kushamiswa nedata kana isu takatozviona?
Pese kana ma charlatan awana pateni, vanofemerwa, vobva vatarisa data yakafanana nokuti muenzaniso wakafanana, kuburitsa mhedzisiro ine p-value yepamutemo kana maviri, padivi pedzidziso yavo. Nokudaro, vari kukunyepera (uye, zvichida, ivo pachavo). Iyi p-value haina basa kana iwe ukasanamatira kune yako hypothesis up to wakaona sei data rako. Charlatans vanotevedzera zviito zvevaongorori nenhamba vasinganzwisisi zvikonzero. Nekuda kweizvozvo, iyo yese ndima ye data sainzi inowana mukurumbira wakashata.
Vechokwadi vezviverengero vanogara vachitora mhedziso dzavo
Kutenda kune ingangoita isinganzwisisike mukurumbira wevaverengera nekuda kwekufunga kwavo kwakasimba, huwandu hweruzivo rwemanyepo muData Sayenzi huri pakakwirira-nguva. Zviri nyore kunyengedza uye kusabatwa, kunyanya kana munhu asingafungire achifunga kuti ndezve equation uye data. Dataset idataset, handiti? Aihwa. Zvine basa kuti unoishandisa sei.

Kusiyana nemacharlatans, vaongorori vakanaka vane pfungwa dzakavhurika uye vanonzwisisa kuti mazano anokurudzira anogona kuve netsananguro dzakawanda dzakasiyana. Panguva imwecheteyo, nyanzvi dzenhamba dzakanaka dzinonyatsotsanangura mhedzisiro yavo vasati vazviita.
Vaongorori havana mhosva ... chero bedzi vachigara mukati mechikamu che data yavo. Kana vakaedzwa kuti vataure chimwe chinhu chavasina kuona, ndiro rimwe basa rose. Vanofanira kubvisa shangu dzeanalyst vopfeka shangu dze statistician. Mushure mezvose, zvisinei kuti zita rebasa ripi, hapana mutemo unoti haugone kudzidza ese maprofessionals kana uchida. Usangovavhiringa.
Kungoti uri shasha pazviverengero hazvireve kuti uri shasha pakuongorora, uye zvakasiyana. Kana mumwe munhu akaedza kukuudza zvakasiyana, unofanira kungwarira. Kana munhu uyu akakuudza kuti zvinotenderwa kutora mhedzisiro yenhamba kubva kune iyo data yawakatodzidza, ichi ndicho chikonzero chekungwarira kaviri.
Tsananguro dzinoshamisa
Paunenge uchitarisa data charlatans musango, uchaona kuti vanoda kugadzira nyaya dzinonakidza kuti "vatsanangure" data ravanoona. Kuwanda kwedzidzo, kuri nani. Hazvina mhosva kuti nyaya idzi dzinogadziridzwa mukuona kwemashure.
Kana matsotsi achiita izvi - regai ndibude pachena - vanonyepa. Hapana huwandu hweequation kana fungidziro dzemhando yepamusoro dzinogona kugadzirira chokwadi chekuti vakapa zero humbowo hwedzidziso dzavo. Usashamiswe kuti tsananguro dzavo hadzina kujairika.
Izvi zvakafanana nekuratidza kugona kwako kwe "psychic" nekutanga kutarisa makadhi ari mumaoko ako uye wozofanotaura zvaunenge wakabata ... zvaunenge wakabata. Uku kurerekera kumashure, uye iyo data sainzi basa yakazadzwa kusvika kumuromo nayo.
Vanoongorora vanoti: "Wangoenda naQueen of Diamonds." Venhamba vanoti, βNdakanyora pfungwa dzangu pabepa iri tisati tatanga. Ngatitambe tichitarisa mamwe data tione kuti ndiri right here." Charlatans anoti: "Ndaiziva kuti uchave Mambokadzi weMadhaimondi nekuti ..."
Kugovana data ndiko kugadzirisa nekukurumidza kunodiwa nemunhu wese.
Kana pasina data yakawanda, iwe unofanirwa kusarudza pakati pezviverengero uye analytics, asi kana pane yakawanda data yakakwana, pane mukana mukuru wekushandisa analytics pasina kunyengera. ΠΈ statistics. Iwe une dziviriro yakakwana kubva kune charlatans - kupatsanurwa kwedata uye, mumaonero angu, iyi ndiyo pfungwa ine simba kwazvo muData Science.
Kuti uzvidzivirire kubva kumakororo, chaunofanirwa kuita kuve nechokwadi chekuti unochengeta data rekuyedza kunze kwekuona kwemaziso avo, uye wobva wabata mamwe ese seanalytics. Paunosangana nedzidziso yekuti uri panjodzi yekubvuma, ishandise kuongorora mamiriro, uye wobva waburitsa yako yakavanzika bvunzo data kuti uone kuti dzidziso yacho haisi nyaya. Zviri nyore!
Ita shuwa kuti hapana anotenderwa kuona bvunzo data panguva yekuongorora. Kuti uite izvi, namatira kune data rekutsvaga. Dhiyabhorosi data haifaniri kushandiswa pakuongorora.
Iri idanho rakakura kubva kune izvo vanhu vajaira munguva ye "diki data", paunofanira kutsanangura kuti unoziva sei zvaunoziva kuitira kuti pakupedzisira utende vanhu kuti iwe unonyatsoziva chimwe chinhu.
Shandisa mitemo yakafanana kune ML / AI
Mamwe macharlatans anozviita seML / AI nyanzvi zvakare ari nyore kuona. Iwe unovabata nenzira imwechete yaunobata chero imwe mainjiniya akaipa: iwo "mhinduro" dzavanoedza kuvaka dzinoramba dzichikundikana. Chiratidzo chekutanga chenyevero kushaikwa kweruzivo neindasitiri yakajairwa programming mitauro nemaraibhurari.
Asi zvakadini nevanhu vanogadzira masisitimu anoita seanoshanda? Unoziva sei kana chimwe chinhu chiri kufungira chiri kuitika? Mutemo mumwe chete unoshanda! Iyo Charlatan ihunhu hwakashata hunokuratidza kuti iyo modhi yakashanda sei ... pane imwechete data yavakashandisa kugadzira modhi.
Kana iwe wakavaka inopenga yakaoma yekudzidza muchina, unoziva sei kunaka kwayo? Iwe hauzoziva kusvika wamuratidza kushanda nedata idzva raasati amboona.
Pawakaona iyo data isati yafanotaura - hazvigoneke zvisati zvaitikaachiudza
Paunenge uine data rakakwana rekuparadzanisa, haufanire kutaura kunaka kwemafomula ako kururamisa chirongwa (chinyakare tsika yandinoona kwese kwese, kwete musainzi chete). Unogona kuti: "Ndinoziva kuti inoshanda nokuti ndinogona kutora data seti yandisati ndamboona uye kufanotaura chaizvo zvichaitika ikoko ... uye ndichave ndakarurama. Zvakare uye zvakare".
