TL;DR yog ib qho kev tshaj tawm rau cov lus nug / lus teb txog Cov Ntaub Ntawv Kev Tshawb Fawb thiab yuav nkag mus rau txoj haujlwm li cas thiab txhim kho hauv nws. Hauv tsab xov xwm kuv yuav txheeb xyuas cov ntsiab lus tseem ceeb thiab FAQ thiab npaj los teb koj cov lus nug tshwj xeeb - sau rau hauv cov lus (lossis hauv cov lus ntiag tug), Kuv yuav sim teb txhua yam hauv ob peb hnub.
Nrog rau qhov tshwm sim ntawm "Dab Ntxwg Nyoog Hnub" series ntawm cov ntawv sau, ntau cov lus thiab cov lus tuaj nrog cov lus nug txog yuav pib li cas thiab khawb qhov twg, thiab hnub no peb yuav txheeb xyuas cov txuj ci tseem ceeb thiab cov lus nug uas tshwm sim tom qab luam tawm.
Txhua yam hais ntawm no tsis lees tias qhov tseeb qhov kawg thiab yog qhov kev xav ntawm tus sau. Peb yuav saib cov khoom tseem ceeb uas zoo li tseem ceeb tshaj plaws hauv cov txheej txheem.
Vim li cas thiaj xav tau qhov no?
Txhawm rau kom lub hom phiaj ua tiav tau zoo dua, kom nws zoo li tsawg kawg yog qee yam tshwj xeeb - koj xav dhau los ua DS lossis Kev Tshawb Fawb Txog Kev Tshawb Fawb ntawm Facebook / Apple / Amazon / Netflix / Google - saib cov cai, hom lus thiab cov txuj ci tsim nyog tshwj xeeb rau txoj haujlwm twg. Txoj kev ntiav neeg ua haujlwm yog dab tsi? Yuav ua li cas ib hnub ib txwm mus dhau ntawm lub luag haujlwm zoo li no? Qhov nruab nrab profile ntawm tus neeg ua haujlwm nyob ntawd zoo li cas?
Feem ntau daim duab tag nrho yog tias tus neeg tsis tshua nkag siab qhov nws xav tau tiag tiag thiab nws tsis meej meej tias yuav npaj li cas rau cov duab tsis meej no - yog li nws tsim nyog muaj tsawg kawg yog ib txoj kev npaj ntxhib ntawm qhov koj xav tau.
Concretize lub hom phiaj saib tam sim no
Txawm hais tias nws hloov pauv ntawm txoj kev, thiab feem ntau nws yog ib txwm hloov cov phiaj xwm thaum lub sijhawm ua si, nws tsim nyog muaj lub hom phiaj thiab tsom mus rau nws, ntsuas lub sijhawm thiab rov xav dua.
Puas yog nws tseem muaj feem cuam tshuam?
Thaum lub sij hawm koj loj hlob mus rau hauv ib txoj hauj lwm.
Xav txog tias ua ntej koj txoj haujlwm koj yuav tsum tau txais PhD, ua haujlwm rau 2-3 xyoo hauv kev lag luam thiab feem ntau txiav koj cov plaub hau thaum xav txog hauv lub tsev teev ntuj - yuav tsis qhov xwm txheej nrog Data Science yuav zoo ib yam li nws ib zaug nrog cov kws lag luam thiab cov kws lij choj? Puas yog txhua yam hloov pauv dhau qhov kev lees paub hauv cheeb tsam koj xav mus nrhiav?
Tsis muaj lub caij nyoog zoo uas txhua leej txhua tus yuav maj nrawm tam sim no thiab peb yuav pom daim duab uas muaj ntau txheej txheej ntawm cov neeg uas tab tom sim nkag mus rau txoj haujlwm - thiab yuav muaj qhov yooj yim pib txoj haujlwm.
Tej zaum nws yuav tsim nyog xav txog cov kev hloov pauv tam sim no thaum xaiv txoj hauv kev, tsis yog lub xeev tam sim no ntawm kev ua lag luam ua haujlwm, tab sis kuj yog koj lub tswv yim ntawm qhov nws hloov pauv thiab qhov twg.
Piv txwv li, tus kws sau ntawv tsis tau npaj los ua Dab Ntxwg Nyoog, tab sis thaum nws PhD nws ua haujlwm ntawm cov neeg sab nrauv uas muaj kev txawj ntse zoo sib xws nrog DS, thiab thaum kawg ntawm kev kawm tiav nws ib txwm hloov mus rau ib puag ncig, pom qhov zoo. txoj hauj lwm.
Yog hais tias thaum lub sij hawm ntawm qhov kev ua si nws hloov tawm hais tias nws yuav tsum tau tsiv mus nyob rau lwm qhov chaw - vim hais tias tam sim no muaj lub feem ntau txav thiab tag nrho cov nthuav tshaj plaws kev txiav txim yog tshwm sim, ces peb yuav tsiv mus nyob ntawd lawm.
Kev txawj ntse
Cov no yog qee yam kev txawj ntse uas zoo li kuv yog qhov tseem ceeb rau kev ua haujlwm puv ntoob thiab ua haujlwm tau zoo hauv DS. Kuv mam li hais lus Askiv nyias - kawm txhua yam koj ua hauv CS. Tom ntej no yog cov pawg tseem ceeb.
Programming/Scripting
Koj paub hom lus dab tsi? Python? Java? Plhaub scripting? Lua? sql? C++?
Dab tsi raws nraim koj yuav tsum muaj peev xwm ua tau thiab yog vim li cas nyob rau hauv cov nqe lus ntawm programming - qhov ntau ntawm txoj hauj lwm ntawm no txawv heev.
Piv txwv li, kuv feem ntau yuav tsum tau siv cov logic nyuaj, cov lus nug, cov qauv, kev tshuaj ntsuam xyuas, thiab feem ntau tsim cov txheej txheem txhais lus, tab sis yuav luag tsis muaj qhov yuav tsum tau ua rau kev ceev ntawm code, tsuas yog cov feem ntau thiab tsim nyog.
Yog li ntawd, kuv cov txheej txheem kev txawj ntse txawv heev los ntawm cov neeg uas sau lub tsev qiv ntawv Tensorflow thiab xav txog kev txhim kho cov cai rau kev siv tau zoo ntawm l1 cache thiab cov khoom zoo sib xws, yog li saib seb koj xav tau dab tsi thiab ntsuas txoj hauv kev rau kev kawm.
Piv txwv li, rau python, tib neeg twb tsim kev kawm lus.
Muaj tseeb tiag, muaj cov lus qhia dhau los thiab qhov chaw zoo rau koj cov kev xav tau - koj yuav tsum tau txiav txim siab ntawm cov npe thiab pib ua haujlwm rau nws.
Nkag siab txog cov txheej txheem ua lag luam
Koj tsis tuaj yeem mus qhov twg yam tsis muaj nws: koj yuav tsum nkag siab tias vim li cas koj thiaj li xav tau hauv txoj haujlwm no, koj ua dab tsi thiab vim li cas. Feem ntau qhov no yog dab tsi tuaj yeem txuag koj ntau lub sijhawm, ua kom koj cov txiaj ntsig zoo tshaj plaws thiab tsis nkim sijhawm thiab cov peev txheej ntawm bullshit.
Feem ntau, kuv nug kuv tus kheej cov lus nug hauv qab no:
- Kuv ua dab tsi hauv lub tuam txhab?
- Vim li cas?
- Leej twg yuav siv nws thiab ua li cas?
- Kuv muaj kev xaiv dab tsi?
- Cov kev txwv ntawm cov kev txwv yog dab tsi?
Nov yog qhov nthuav dav me ntsis txog qhov tsis: koj tuaj yeem hloov pauv qhov xwm txheej ua haujlwm tau zoo heev yog tias koj paub tias qee yam tuaj yeem txi: piv txwv li, kev txhais lus lossis qhov sib txawv, ob peb feem pua ββββyuav tsis ua lub luag haujlwm ntawm no thiab peb muaj kev nrawm heev. kev daws teeb meem, thiab cov neeg siv khoom xav tau nws, vim nws them rau lub sijhawm cov raj xa dej tau khiav hauv AWS.
Kev ua lej
Ntawm no koj xav thiab nkag siab txhua yam ntawm koj tus kheej - tsis muaj kev paub txog lej yooj yim koj tsis muaj dab tsi ntau tshaj li cov liab nrog lub grenade (thov txim Random Forest) - yog li koj yuav tsum nkag siab yam tsawg kawg nkaus. Yog tias kuv tau sau ib daim ntawv teev npe tsawg heev, nws yuav suav nrog:
- Linear algebra - ib tug loj tus naj npawb ntawm cov kev pab cuam yog ib qho yooj yim rau Google, nrhiav dab tsi suits koj zoo tshaj plaws;
- Kev txheeb xyuas lej - (tsawg kawg hauv thawj ob lub semesters);
- Qhov kev xav tau muaj nyob txhua qhov chaw hauv kev kawm tshuab;
- Combinatorics - nws yog qhov ua tau ntxiv rau txoj kev xav;
- Graph txoj kev xav - yam tsawg kawg yog BASIC;
- Algorithms - tsawg kawg rau thawj ob lub semesters (saib Cormen cov lus pom zoo hauv nws phau ntawv);
- Mathlogic - yam tsawg kawg nkaus.
Kev tsom xam cov ntaub ntawv siv tau thiab ua kom pom tseeb
Ib qho tseem ceeb tshaj plaws yog kom tsis txhob ntshai ua kom koj txhais tes qias neeg nrog cov ntaub ntawv thiab ua qhov kev ntsuam xyuas dav dav ntawm dataset, qhov project, thiab tsim kom pom cov ntaub ntawv ceev.
Kev tshawb xyuas cov ntaub ntawv yuav tsum tsuas yog ua tej yam ntuj tso, zoo li tag nrho lwm cov ntaub ntawv hloov pauv thiab muaj peev xwm los tsim cov kav dej yooj yim los ntawm unix nodes (saib cov ntawv dhau los) lossis sau ntawv nyeem tau thiab nkag siab.
Kuv xav hais txog kev pom: nws zoo dua los pom ib zaug dua li hnov ββββib puas zaus.
Qhia daim duab rau tus thawj tswj hwm yog ib puas npaug yooj yim thiab meej dua li cov lej, yog li matplotlib, seaborn thiab ggplot2 yog koj cov phooj ywg.
Kev txawj ntse
Nws yog ib qho tseem ceeb sib npaug kom muaj peev xwm sib txuas lus koj cov tswv yim, nrog rau cov txiaj ntsig thiab kev txhawj xeeb (thiab lwm yam) rau lwm tus - xyuas kom meej tias koj tuaj yeem hais meej txog txoj hauj lwm hauv ob qho tib si technical thiab kev lag luam.
Koj tuaj yeem piav qhia rau cov npoj yaig, cov thawj coj, cov thawj coj, cov neeg siv khoom thiab lwm tus neeg uas xav tau qhov tshwm sim, cov ntaub ntawv twg koj siv thiab cov txiaj ntsig koj tau txais.
Koj cov kab kos thiab cov ntaub ntawv yuav tsum tau nyeem yam tsis muaj koj. Ntawd yog, koj tsis tas yuav mus rau koj kom nkag siab qhov uas tau sau rau ntawd.
Koj tuaj yeem ua qhov kev nthuav qhia meej kom tau txais cov ntsiab lus hla thiab / lossis sau cov phiaj xwm / koj txoj haujlwm.
Koj tuaj yeem qhia koj txoj haujlwm hauv qhov laj thawj thiab tsis txaus siab, hais "yog / tsis" lossis nug / txhawb kev txiav txim siab.
Kev cob qhia kev cob qhia
Muaj ntau qhov chaw sib txawv uas koj tuaj yeem kawm tag nrho cov no. Kuv yuav muab cov npe luv luv - Kuv sim txhua yam los ntawm nws thiab, kom ncaj ncees, txhua yam khoom muaj nws qhov zoo thiab qhov tsis zoo. Sim nws tawm thiab txiav txim siab seb qhov twg haum rau koj, tab sis kuv xav kom sim ntau txoj kev xaiv thiab tsis txhob daig ntawm ib qho.
- Cov chav kawm online: coursera, udacity, Edx, thiab lwm yam;
- Cov tsev kawm ntawv tshiab: online thiab offline - SkillFactory, ShAD, MADE;
- Classical tsev kawm ntawv: university master's programs thiab kev cob qhia qib siab;
- Cov Haujlwm - koj tuaj yeem xaiv cov haujlwm uas koj nyiam thiab txiav lawv, xa lawv mus rau github;
- Kev xyaum ua haujlwm - nws nyuaj rau kev qhia txhua yam ntawm no; koj yuav tsum nrhiav yam muaj thiab nrhiav cov kev xaiv tsim nyog.
Puas tsim nyog?
Hauv kev xaus, Kuv yuav zaum ntxiv peb tus kheej lub hauv paus ntsiab lus uas kuv sim ua raws li kuv tus kheej.
- Yuav tsum nthuav;
- Nqa kev zoo siab (= yam tsawg kawg tsis ua rau kev txom nyem);
- "Yuav ua koj li."
Vim li cas lawv? Nws yog ib qho nyuaj rau xav txog ua ib yam dab tsi txhua hnub thiab tsis txaus siab rau nws los yog tsis nyiam. Xav txog tias koj yog tus kws kho mob thiab koj ntxub kev sib txuas lus nrog tib neeg - qhov no, ntawm chav kawm, tuaj yeem ua haujlwm li cas, tab sis koj yuav tsis xis nyob tas li nrog cov neeg mob uas xav nug koj ib yam dab tsi. Qhov no tsis ua haujlwm ntev.
Vim li cas kuv thiaj hais txog kev txaus siab sab hauv? Nws zoo nkaus li kuv tias qhov no yog qhov tsim nyog rau kev txhim kho ntxiv thiab, ntawm txoj cai, txoj kev kawm. Kuv yeej txaus siab rau nws thaum kuv tswj kom ua tiav qee qhov kev ua haujlwm nyuaj thiab tsim ib tus qauv lossis xam qhov tseem ceeb. Kuv txaus siab rau nws thaum kuv tus lej zoo nkauj zoo nkauj thiab sau tau zoo. Yog li ntawd, kev kawm ib yam dab tsi tshiab yog qhov nthuav thiab tsis ncaj qha yuav tsum muaj kev txhawb nqa tseem ceeb.
"Ua koj li" yog qhov kev xav zoo ib yam tias qhov no yog qhov koj xav ua. Kuv muaj ib zaj dab neeg me me. Txij li thaum yau, kuv tau nyiam suab paj nruag pob zeb (thiab hlau - SALMON!) thiab, zoo li ntau lwm tus, kuv xav kawm ua si thiab qhov ntawd yog txhua yam. Nws hloov tawm tias kuv tsis hnov ββββlus thiab tsis muaj lub suab - qhov no tsis thab kuv kiag li (thiab kuv yuav tsum hais tias qhov no tsis thab ntau tus neeg ua yeeb yam nyob rau theem), thiab thaum kuv tseem nyob hauv tsev kawm ntawv kuv tau txais guitar ... thiab Nws tau pom tseeb tias kuv tsis nyiam zaum ntau teev thiab ua si rau nws. Nws tau mus nyuaj, nws ib txwm zoo li rau kuv tias qee yam kev thab plaub tawm tuaj - Kuv tsis tau txais kev txaus siab los ntawm nws thiab tsuas yog xav tias tsis zoo, ruam thiab tsis muaj peev xwm. Kuv hais yuam kom kuv tus kheej zaum rau cov chav kawm thiab feem ntau nws tsis yog zaub mov zoo rau tus nees.
Nyob rau tib lub sijhawm, kuv tuaj yeem ua siab ntev zaum rau cov sij hawm tsim qee yam khoom ua si, siv cov ntawv los ua ib yam dab tsi ntawm flash (lossis lwm yam) thiab kuv tau mob siab rau kom ua tiav cov ntsiab lus hauv qhov kev ua si lossis cuam tshuam nrog cov cuab yeej ntawm kev txav thiab / lossis txuas cov tsev qiv ntawv thib peb, plugins thiab lwm yam.
Thiab qee lub sijhawm kuv pom tau hais tias kev ua si guitar tsis yog kuv li thiab kuv nyiam mloog, tsis ua si. Thiab kuv ob lub qhov muag ci ntsa iab thaum kuv sau cov kev ua si thiab cov lej (nrhiav txhua hom hlau thaum lub sijhawm ntawd) thiab qhov ntawd yog qhov kuv nyiam thaum ntawd, thiab qhov ntawd yog qhov kuv yuav tsum tau ua.
Koj puas muaj lwm yam lus nug?
Tau kawg, peb tsis tuaj yeem hla tag nrho cov ncauj lus thiab cov lus nug, yog li sau cov lus thiab PM kuv - Kuv ib txwm zoo siab muaj lus nug.
