TL; DR inzvimbo yemibvunzo / mhinduro nezve data Sayenzi uye maitiro ekupinda hunyanzvi uye kusimudzira mariri. Muchinyorwa ini ndichaongorora misimboti yekutanga uye FAQ uye ndakagadzirira kupindura yako chaiyo mibvunzo - nyora mune zvakataurwa (kana mune yakavanzika meseji), ini ndichaedza kupindura zvese mukati memazuva mashoma.
Nekuuya kwe "Satanist Date" mutsara wezvinyorwa, mameseji mazhinji nemhinduro zvakauya nemibvunzo nezvekuti ungatanga sei uye kupi kuchera, uye nhasi tichaongorora hunyanzvi hunyanzvi uye mibvunzo yakamuka mushure mezvinyorwa.
Zvese zvakataurwa pano hazvireve kuti ichokwadi chekupedzisira uye ndiwo maonero emunyori. Tichatarisa pazvinhu zvikuru zvinoita sezvinonyanya kukosha mukuita.
Neiko ikoku kuchidikanwa chaizvoizvo?
Kuti chinangwa chigone kuitika zvirinani, kuitira kuti chitaridzike zvakati tsvikiti - iwe unoda kuve DS kana Research Scientist paFacebook/Apple/Amazon/Netflix/Google - tarisa zvinodiwa, mitauro uye hunyanzvi hunodiwa. kunyanya nokuda kwechinzvimbo chipi. Ndeipi nzira yekubhadhara? Zuva remazuva ose rinofamba sei mubasa rakadaro? Ko avhareji yeprofile yemunhu anoshanda ipapo inoita sei?
Kazhinji mufananidzo wakazara ndewekuti munhu haanyatsonzwisisa zvaanoda chaizvo uye hazvina kunyatsojeka kuti ungagadzirira sei mufananidzo uyu usina kujeka - saka zvakakosha kuve nechero chirongwa chakaomarara chezvaunoda chaizvo.
Gadzirisa chinangwa chazvino chekutarisa
Kunyangwe ikachinja munzira, uye zvakajairika kushandura zvirongwa panguva yekutamba, zvakakosha kuve nechinangwa uye kuisa pfungwa pazviri, nguva nenguva uchiongorora nekufunga patsva.
Zvichava here kana kuti zvichiri kukosha?
Nenguva yaunokura kuita chinzvimbo.
Fungidzira kuti pamberi pechinzvimbo chako iwe unofanirwa kuwana PhD, shanda kwemakore 2-3 muindasitiri uye kazhinji kugera bvudzi rako uchifungisisa mune imwe monastery - hazvizoiti here mamiriro ezvinhu neData Science akafanana neaimbova economist uye magweta? Zvese zvichachinja kupfuura kuzivikanwa munzvimbo yaunoda kutevera?
Hapana here mukana wakanaka wekuti munhu wese amhanyire ikoko izvozvi uye isu tichaona pikicha paine huwandu hwakakura hwevanhu vari kuyedza kupinda hunyanzvi - uye pachave nenzvimbo shoma yekutanga.
Zvingave zvakakosha kuti utarise maitiro azvino kana uchisarudza nzira, kwete chete mamiriro azvino emusika wevashandi, asiwo zano rako rekuchinja kwairi uye kwairi.
Semuenzaniso, munyori haana kuronga kuve muSatanist, asi panguva yePhD yake akashanda pamapurojekiti ebato rechitatu aive nehunyanzvi hwakasimba hwakafanana neDS, uye pakupera kwekupedza chikoro akachinjira kune zvakatipoteredza, achiona zvakanaka. chinzvimbo.
Kana panguva yemutambo zvikaitika kuti zvichave zvakakodzera kutamira kune imwe nzvimbo - nokuti pane ikozvino kufamba kwakanyanya uye zvose zvinonakidza chiito chiri kuitika, ipapo tichaenda ikoko zvakasikwa.
Skill Breakdown
Aya ndiwo mapoka eunyanzvi anoratidzika kwandiri sekiyi yebasa rakazara uye rinoshanda muDS. Ini ndichasimbisa Chirungu zvakasiyana - dzidza chero chaunoita muCS. Zvinotevera ndiwo mapoka makuru.
Programming/Scripting
Ndeipi mitauro yaune chokwadi chekujairana nayo? Python? Java? Shell kunyora? Lua? Sql? C++?
Chii chaizvo chaunoda kuti ukwanise kuita uye nei maererano nehurongwa - huwandu hwezvinzvimbo pano hunosiyana zvakanyanya.
Semuyenzaniso, ini kazhinji ndinofanira kuita yakaoma logic, mibvunzo, modhi, analytics, uye kazhinji kugadzira akadudzirwa masisitimu, asi pane zvisingambofi zvakadikanwa zvekumhanya kwekodhi, kunze kweiyo yakawanda uye inonzwisisika.
Naizvozvo, hunyanzvi hwangu seti hwakasiyana kwazvo neavo vanonyora Tensorflow raibhurari uye funga nezve optimize kodhi yekushandisa zvakanaka l1 cache nezvimwe zvakafanana, saka tarisa izvo chaizvo zvaunoda uye ongorora nzira chaiyo yekudzidza.
Semuenzaniso, kune python, vanhu vanotogadzira kudzidza mutauro.
Chokwadi, pane zvatove nemazano ane ruzivo uye masosi akanaka ezvaunoda - iwe unofanirwa kusarudza pane rondedzero uye wotanga kushanda pairi.
Kunzwisisa maitiro ebhizinesi
Iwe haugone kuenda chero kupi zvako usina: iwe unofanirwa kunzwisisa kuti sei iwe uchidikanwa mune iyi maitiro, zvauri kuita uye nei. Izvi kazhinji ndizvo zvinogona kukuchengetedza toni yenguva, kuwedzera mabhenefiti ako, uye kudzivirira kutambisa nguva nezviwanikwa pa crap.
Kazhinji, ndinozvibvunza mibvunzo inotevera:
- Chii chaizvo chandinoita mukambani?
- Sei?
- Ndiani achaishandisa uye sei?
- Ndedzipi sarudzo dzandiinadzo?
- Ndeipi miganhu yemaparamita?
Heano zvimwe zvakadzama nezve parameters: iwe unogona kazhinji kushandura zvakanyanya mamiriro ebasa kana iwe uchiziva kuti chimwe chinhu chinogona kubayirwa: semuenzaniso, kududzira kana zvakasiyana, mashoma muzana haazoite basa pano uye isu tine kukurumidza kwazvo. mhinduro, uye mutengi anoida, nekuti anobhadhara iyo nguva iyo pombi iri kushanda muAWS.
Mathematics
Pano iwe unofunga uye unonzwisisa zvese iwe pachako - pasina ruzivo rwemasvomhu ekutanga iwe hausi chinhu kunze kwetsoko dzine grenade (ndine hurombo Random Sango) - saka iwe unofanirwa kunzwisisa zvishoma izvo zvakakosha zvinhu. Dai ndaizogadzira rondedzero shoma, yaizosanganisira:
- Linear algebra - nhamba huru yezviwanikwa zviri nyore kuGoogle, tsvaga zvinokunakira iwe;
- Kuongorora kwemasvomhu - (zvichida mumasemesita maviri ekutanga);
- Probability theory iri kwese kwese mukudzidza kwemichina;
- Combinatorics - zvinonyatsoenderana nedzidziso;
- Girafu dzidziso - zvishoma BASIC;
- Algorithms - ingangoita semesita maviri ekutanga (ona kurudziro yaCormen mubhuku rake);
- Mathlogic - zvirinani zvakakosha.
Kushanda data kuongororwa uye kuona
Chimwe chezvinhu zvinonyanya kukosha kugona kusatya kusvibisa maoko ako nedata uye kuita ongororo yakazara yedataset, purojekiti, uye kugadzira kukurumidza kuona data.
Ongororo yedata yekuongorora inofanirwa kungove chinhu chakasikwa, senge mamwe ese ekuchinja data uye kugona kugadzira pombi iri nyore kubva kune unix node (ona zvinyorwa zvakapfuura) kana kunyora bhuku rinoverengwa uye rinonzwisisika.
Ndinoda kutaura kuona: zviri nani kuona kamwe pane kunzwa kazana.
Kuratidza girafu kune maneja kuri nyore uye kwakajeka zvakapetwa kazana pane seti yenhamba, saka matplotlib, seaborn uye ggplot2 ishamwari dzako.
Unyanzvi hwakapfava
Zvinokosha zvakaenzana kuti ukwanise kutaura pfungwa dzako, pamwe nemhedzisiro uye zvinokunetsa (nezvimwe.) kune vamwe - ita shuwa kuti unokwanisa kutaura zvakajeka basa racho mune zvese zvehunyanzvi uye zvebhizinesi mazwi.
Iwe unogona kutsanangurira vaunoshanda navo, maneja, vakuru, vatengi uye chero ani zvake anoida izvo zviri kuitika, ndeapi data rauri kushandisa uye kuti ndeapi mhedzisiro yawakawana.
Machati ako uye zvinyorwa zvinofanirwa kuverengwa pasina iwe. Ndiko kuti, haufanire kuenda kwauri kuti unzwisise zvakanyorwa ipapo.
Iwe unogona kuita mharidzo yakajeka kuti uwane poindi uye/kana kunyora purojekiti/basa rako.
Iwe unogona kutaura chinzvimbo chako nenzira ine mufungo uye isina tsitsi, taura "hongu / kwete" kana mubvunzo / tsigira sarudzo.
Kudzidzisa zvidzidzo
Kune nzvimbo dzakawanda dzakasiyana kwaunogona kudzidza zvese izvi. Ini ndichapa runyoro rupfupi - ndakaedza zvese kubva pazviri uye, kutaura chokwadi, chinhu chimwe nechimwe chine zvachakanakira nezvacho. Edza kunze uye sarudza izvo zvinokukodzera, asi ini ndinokurudzira zvikuru kuedza akati wandei sarudzo uye kusanamira pane imwe.
- Online makosi: coursera, udacity, Edx, nezvimwe;
- Zvikoro zvitsva: online uye kunze kwenyika - SkillFactory, ShaD, MADE;
- Zvikoro zveClassical: zvirongwa zvevatenzi veyunivhesiti uye makosi epamusoro ekudzidzira;
- Mapurojekiti - iwe unogona kungosarudza mabasa anokufarira uye woacheka, uchiaisa kune github;
- Internship - zvakaoma kupa chero chinhu pano; iwe unofanirwa kutsvaga izvo zviripo uye nekuwana sarudzo dzakakodzera.
Zvinofanira here?
Mukupedzisa, ini ndichawedzera misimboti mitatu yandinoedza kutevera pachangu.
- Zvinofanira kunakidza;
- Hunza kunakidzwa kwemukati (= zvishoma kwete kukonzera kutambura);
- "Kuva wako."
Nei vakadaro? Zvakaoma kufungidzira kuita chimwe chinhu zuva nezuva usinganakidzwi nacho kana kusafarira. Fungidzira kuti iwe uri chiremba uye unovenga kutaurirana nevanhu - izvi, zvechokwadi, zvinogona kushanda neimwe nzira, asi iwe uchange uchigara uchinetseka nekuyerera kwevarwere vanoda kukubvunza chimwe chinhu. Izvi hazvishande mukufamba kwenguva.
Sei ndakanyatsotaura mafaro emukati? Zvinoratidzika kwandiri kuti izvi zvakakosha kune imwe budiriro uye, mumusimboti, maitiro ekudzidza. Ini ndinonakidzwa nazvo pandinokwanisa kupedzisa imwe yakaoma chimiro uye kuvaka modhi kana kuverenga yakakosha parameter. Ndinonakidzwa nazvo kana kodhi yangu ichiyevedza uye yakanyorwa zvakanaka. Naizvozvo, kudzidza chimwe chinhu chitsva kunonakidza uye hakudi zvakananga chero chikonzero chakakosha.
"Kuva wako" manzwiro mamwe chete ekuti izvi ndizvo zvawaida kuita. Ndine kanyaya kadiki. Kubva ndichiri mudiki, ndanga ndichifarira mumhanzi werock (uye simbi - SALMON!) Uye, sevamwe vazhinji, ndaida kudzidza kutamba uye ndizvo chete. Zvakazoitika kuti ndakanga ndisinganzwe uye ndisina inzwi - izvi hazvina kundinetsa zvachose (uye ndinofanira kutaura kuti izvi hazvinetse vatambi vazhinji padanho), uye ndichiri kuchikoro ndakawana gitare ... uye zvakava pachena kuti handidi chaizvo kugara kwemaawa ndichitamba pairi. Zvakanga zvichienda zvakaoma, zvaigara zvichiratidzika kwandiri kuti imwe mhando yebullshit yaibuda - ini handina kuwana mufaro kubva mairi zvachose uye ndaingonzwa kusurukirwa, kupusa uye kusakwanisa zvachose. Ndakazvimanikidza kuti ndigare pasi kuti ndiite zvidzidzo uye kazhinji kacho kwaisava chikafu chakanaka chebhiza.
Panguva imwe cheteyo, ndaigona kugara ndakadzikama kwemaawa ndichigadzira matoyi, ndichishandisa chinyorwa kuratidza chimwe chinhu paflash (kana chimwewo chinhu) uye ndaikurudzirwa kupedzisa zvinhu mumutambo kana kubata nemakanika ekufamba uye/ kana. kubatanidza maraibhurari ebato rechitatu, plugins nezvimwe zvese.
Uye pane imwe nguva ndakaona kuti kuridza gitare hakusi kwangu uye kuti ndinoda chaizvo kuteerera, kwete kutamba. Uye maziso angu akapenya pandakanyora mitambo nekodhi (kuteerera kune marudzi ose esimbi panguva iyoyo) uye ndizvo zvandaifarira ipapo, uye ndizvo zvandaifanira kunge ndichiita.
Une mimwe mibvunzo here?
Ehe, isu hatina kukwanisa kuenda nemisoro yese nemibvunzo, saka nyora mhinduro uye PM me - ndinogara ndichifara kuva nemibvunzo.
