Kuphunzira koyamba pamanja. Yandex.Workshop - Katswiri wa Data

Ndimagawana zomwe ndakumana nazo pakuphunzitsidwa mu Yandex.Practicum kwa iwo omwe angafune kupeza luso linalake kapena kuchoka kuzinthu zina. Ndikatcha gawo loyamba pantchitoyo, m'malingaliro anga omvera. Zimakhala zovuta kudziwa zomwe ziyenera kuphunziridwa, chifukwa aliyense ali ndi chidziwitso chochuluka, ndipo maphunzirowa adzakuphunzitsani zambiri, ndipo aliyense adzimvetsetsa yekha zomwe angafunikire kuti adziwe zambiri. - pafupifupi nthawi zonse, maphunziro owonjezera aulere adzakhala okwanira.

Kodi ndinafika bwanji ku "lingaliro" la analytics?

Kwa zaka zingapo iye anali nawo pa chilengedwe cha masitolo Intaneti ndi kukonza (malonda, malonda, Yandex.Direct, etc.). Ndinkafuna kuchepetsa kuchuluka kwa ntchito yanga ndikuchita zinthu zokhazo kuchokera pagulu lalikululi lomwe ndimakonda kwambiri. Komanso, sindimadziwa dzina la ntchito yanga yamtsogolo, panali zofunikira zokhazokha za ntchitoyo. Mapulogalamu ophunzirira ndi zida ndekha sizinakhalepo chopinga kwa ine, kotero ndinaganiza zoyang'ana komwe ndingagwiritse ntchito zomwe ndakumana nazo ndikuphunzira zinthu zatsopano.

Poyamba ndinaganiza zopeza maphunziro apamwamba achiwiri kapena kuphunzitsidwanso mwaukadaulo, popeza maphunzirowo ankawoneka ngati chinthu chopanda pake. Ndikuyang'ana njira zosiyanasiyana, mwangozi ndinapeza Yandex.Practice. Panali ntchito zochepa, pakati pawo panali katswiri wa deta, kufotokozera kunali kosangalatsa.

Ndinayamba kuphunzira zomwe zilipo mu analytics chidziwitso ponena za kupeza maphunziro apamwamba achiwiri, koma zinapezeka kuti nthawi yophunzitsira ndi yaitali kwambiri kudera limene zonse zikusintha mofulumira kwambiri; mabungwe apamwamba sangakhale ndi nthawi yoti ayankhe. ku izi. Ndinaganiza zowona zomwe msika umapereka kuwonjezera pa Workshop. Ambiri mwa omwe adatenga nawo gawo adaperekanso zaka zazitali za 1-2, koma ndikufuna chitukuko chofananira: kulowa ntchito m'malo otsika komanso maphunziro opitilira.

Zomwe ndimafuna pantchitoyo (sindiganizira ntchito)

• Ndinkafuna kuti maphunziro akhale okhazikika pantchito yanga,
• Ndimachita bwino ndi maopaleshoni anthawi zonse ndikawona cholinga chosangalatsa, koma ndinkafuna kuchita zinthu zambiri kuti ntchitoyo isakhale ndi zochita zingapo zamakina,
• kotero kuti ndizofunikira kwambiri ndi bizinesi osati kokha (msika wokha umatsimikizira izi mu rubles kapena madola),
• panali chinthu chodziyimira pawokha, udindo, "kuzungulira kwathunthu",
• panali malo oti akule (panthawiyi ndikuwona ngati kuphunzira kwamakina ndi ntchito zasayansi).

Chifukwa chake, kusankha kudagwera pa Yandex.Practicum chifukwa cha:

• nthawi yophunzira (miyezi isanu ndi umodzi yokha),
• otsika polowera - adalonjeza kuti ngakhale ndi maphunziro a sekondale mutha kudziwa bwino ntchito,
• mtengo,
• adzabweza ndalamazo ngati mumvetsetsa kuti ntchitoyi si yoyenera kwa inu (pali malamulo ena omwe ali abwino),
• yesetsani ndikuchitanso - mapulojekiti othandiza omwe adzaphatikizidwe pagawoli (ndinawona kuti izi ndizofunikira kwambiri),
• mawonekedwe a intaneti, chithandizo,
• maphunziro oyambira aulere pa Python, komanso pakadali pano mukumvetsetsa ngati mukuzifuna,
• Komanso, muyenera kuganizira mtundu wanji wa kukumbukira muli. Kuthamanga ndi kupambana kwa maphunziro kudzadalira izi. Ndikofunikira kwambiri kwa ine kuti zida zophunzitsira zili m'malemba, popeza ine ndekha ndili ndi kukumbukira kowoneka bwino kwambiri. Mwachitsanzo, Geekbrains ili ndi zida zonse zophunzitsira mumavidiyo (malinga ndi chidziwitso cha maphunzirowa). Kwa iwo omwe amazindikira chidziwitso ndi khutu, mawonekedwe awa angakhale abwino kwambiri.

Zowawa:

• adalowa mumtsinje woyamba ndikumvetsetsa kuti, monga china chilichonse chatsopano, padzakhala zolakwika zaukadaulo,
• Ndinazindikira kuti panalibe funso la ntchito iliyonse yokakamiza.

Kodi maphunziro akuyenda bwanji?

Kuti muyambe, muyenera kutenga maphunziro oyambira aulere pa Python ndikumaliza ntchito zonse, chifukwa ngati simumaliza yapitayo, yotsatirayo sidzawoneka. Ntchito zonse zotsatila mu maphunzirowa zimakonzedwa motere. Ikufotokozanso kuti ntchitoyo ndi chiyani komanso ngati kuli koyenera kuchita maphunzirowo.

Thandizo litha kulandiridwa pa Facebook, VKontakte, Telegraph ndi kulumikizana koyambira mu Slack.
Kuchuluka kwakulankhulana mu Slack kumachitika ndi mphunzitsi pamene akumaliza simulator komanso pomaliza ntchitoyo.

Mwachidule za zigawo zikuluzikulu

Timayamba maphunziro athu pofufuza za Python ndikuyamba kugwiritsa ntchito Jupyter Notebook kukonzekera ntchito. Kale pa gawo loyamba tikuchita ntchito yoyamba. Palinso mawu oyamba a ntchitoyo ndi zofunika zake.

Pa gawo lachiwiri, timaphunzira za kukonza deta, m'mbali zake zonse, ndikuyamba kuphunzira ndi kusanthula deta. Apa mapulojekiti ena awiri akuwonjezedwa ku mbiri.

Ndiye pali maphunziro a statistical data analysis + project.

Chachitatu choyamba chatsirizidwa, tikuchita ntchito yaikulu yokonzedweratu.

Maphunziro owonjezera pakugwira ntchito ndi nkhokwe ndikugwira ntchito muchilankhulo cha SQl. Ntchito ina.
Tsopano tiyeni tifufuze mozama mu kusanthula ndi kusanthula malonda ndipo, ndithudi, polojekiti.
Chotsatira - zoyesera, zongoyerekeza, kuyesa kwa A / B. Ntchito.
Tsopano chiwonetsero chazithunzi za data, chiwonetsero, Library ya Seaborn. Ntchito.

Chachitatu chachitatu chatsirizidwa - ntchito yaikulu yophatikizidwa.

Automation of data analysis process. Stream analytics mayankho. Dashboards. Kuyang'anira. Ntchito.
Ma analytics oneneratu. Njira zophunzirira makina. Linear regression. Ntchito.

NTCHITO YOPHUNZITSA ZOPHUNZITSA. Malingana ndi zotsatira, timalandira chiphaso cha maphunziro owonjezera.

Ntchito zonse zomwe zikuchitika ndizomwe zimagwiritsidwa ntchito m'mabizinesi osiyanasiyana: mabanki, malo ogulitsa, malo ogulitsira pa intaneti, zinthu zazidziwitso, ndi zina zambiri.

Ntchito zonse zimafufuzidwa ndi alangizi a Yandex.Practice - akatswiri ogwira ntchito. Kulankhulana nawo kunakhalanso kofunika kwambiri, amandilimbikitsa, koma kwa ine chinthu chofunika kwambiri ndikuchita zolakwika.

Gawo lofunikira ndi misonkhano yamakanema ndi alangizi ndi maphunziro apakanema ndi akatswiri oitanidwa.

Palinso maholide)) - sabata imodzi pakati pa magawo awiri pa atatu aliwonse. Ngati ndondomekoyi ikupita motsatira ndondomeko, mumapumula, ndipo ngati sichoncho, ndiye kuti mumamaliza michira. Palinso tchuthi chophunzirira kwa iwo omwe, pazifukwa zina, amayenera kuyimitsa maphunziro awo.

Pang'ono za simulator

Maphunzirowa ndi atsopano, koma mwachiwonekere kutengera maphunziro ena, akatswiri a Yandex amadziwa momwe zimakhalira zovuta nthawi zina pamene pali zambiri ndipo chidziwitso "sichimalowa." Chifukwa chake, tasankha kusangalatsa ophunzira momwe tingathere ndi zojambula zoseketsa ndi ndemanga, ndipo ndiyenera kunena, izi zidathandizira kwambiri panthawi yotaya mtima pamene "mukuvutikira" ntchito.

Ndipo nthawi zina kukhumudwa kumakhalapo:

• Inu, mudamaliza maphunziro awo ku yunivesite nthawi yayitali ndipo simukuwoneka kuti mukukumbukira kalikonse, ndiyeno mukuwona mutu wa mutu wakuti "Normal approximation of the binomial distribution" ndikusiya, ndikuganiza kuti simudzatero. mvetsetsani izi, koma pambuyo pake malingaliro onse ndi ziwerengero zonse zimakhala zomveka komanso zosangalatsa kwa inu,
• kapena mupeza izi:

  

Malangizo kwa ophunzira amtsogolo: 90% ya zolakwika zimayamba chifukwa cha kutopa kapena kulemedwa ndi chidziwitso chatsopano. Pumulani kwa theka la ola kapena ola ndikuyesanso, monga lamulo, panthawiyi ubongo wanu udzakonza ndikusankha zonse)). Ndipo 10% ngati simukumvetsa mutuwo - werenganinso kachiwiri ndipo zonse zikhala bwino!

Pa maphunzirowa, pulogalamu yapadera idawoneka yothandiza pantchito: kujambulanso zoyambira, makalata oyambira, kujambula mbiri, kukonzekera zoyankhulana, ndi zina zotero, ndi akatswiri ochokera ku dipatimenti ya HR. Izi zinakhala zofunikira kwambiri kwa ine, chifukwa ndinazindikira kuti sindinapiteko ku zokambirana kwa zaka zambiri.

Pokhala pafupi kumapeto kwa maphunziro anga, nditha kulangiza zomwe ndiyenera kukhala nazo:

• chodabwitsa, chidwi chowunikira, kuthekera kopanga maubwenzi omveka, kuganiza kwamtunduwu kuyenera kukhala kopambana,
• luso ndi chikhumbo cha kuphunzira siziyenera kutayika (muyenera kuphunzira zambiri nokha), izi ndizowonjezera, za gulu la anthu oposa 35,
• monga banal, koma ndibwino kuti musayambe ngati chilimbikitso chanu chili chochepa "Ndikufuna kupeza zambiri / zambiri."

Zoipa komanso zoyembekeza zosayenera, kodi tikanakhala kuti popanda izo?

• Amalonjeza kuti ndi maphunziro a sekondale aliyense akhoza kumvetsetsa.

  Osati zoona, ngakhale maphunziro a sekondale akadali osiyana. Ndikukhulupirira, monga munthu yemwe amakhala m'nthawi zakale)), pomwe panalibe kugwiritsa ntchito intaneti mofala, kuti payenera kukhala zida zokwanira zolingalira. Ngakhale, chilimbikitso chachikulu chidzagonjetsa chirichonse.

• Kulimba mtima kudakhala kokwezeka kwambiri.

  Zidzakhala zovuta kwa iwo omwe akugwira ntchito (makamaka kumunda kutali ndi izi), mwinamwake zingakhale bwino kugawanso nthawi osati mofanana pakati pa maphunziro, koma ndi gawo loyamba lachitatu, ndi zina zotero mu dongosolo lotsika.

• Monga momwe amayembekezera, panali zovuta zaukadaulo.

  Monga munthu wochita nawo ntchito zozungulira, ndikumvetsetsa kuti, poyamba, sizingatheke popanda mavuto aukadaulo. Anyamatawo adayesetsa kwambiri kukonza zonse mwachangu momwe angathere.

• Mphunzitsi nthawi zonse samayankha pa nthawi yake ku Slack.

  "Pa nthawi" ndi mfundo ziwiri, mu nkhani iyi, pa nthawi, nthawi muyenera, popeza ntchito ophunzira kugawa nthawi yophunzira ndi liwiro kuyankha mafunso n'kofunika kwambiri kwa iwo. Tikufuna aphunzitsi ambiri.

• Magwero akunja (nkhani, maphunziro owonjezera) amafunikira.

  Nkhani zina zimalimbikitsidwa ndi Yandex.Practicum, koma izi sizokwanira. Ndikhoza kulangiza, mofanana, kuonjezera maphunziro a Stepik - Big Data kwa oyang'anira (zachitukuko chachikulu), Programming mu Python, Basics of Statistics, magawo onse awiri ndi Anatoly Karpov, Mau oyamba ku Databases, Theory Theory (ma module 2 oyambirira).

Pomaliza

Pazonse, maphunzirowa achita bwino kwambiri ndipo akufuna kukhala ophunzitsa komanso olimbikitsa. Ndikufunikabe kudziŵa zinthu zambiri, koma tsopano sizindiwopsyeza, ndili ndi ndondomeko yogwira ntchito. Mtengo wake ndi wotsika mtengo kwambiri - malipiro amodzi kwa katswiri pa malo otsika kwambiri. Zochita zambiri. Thandizani pa chilichonse kuyambira zoyambira mpaka zogulira khofi.
