Dzina langa ndine Sasha ndipo ndimakonda kuphunzira pamakina komanso kuphunzitsa anthu. Tsopano ndimayang'anira mapulogalamu a maphunziro ku Computer Science Center ndikuwongolera pulogalamu ya bachelor mu kusanthula deta ku St. Petersburg State University. Izi zisanachitike, adagwira ntchito ngati katswiri pa Yandex, ndipo ngakhale m'mbuyomu ngati wasayansi: adachita masamu ku Institute of Computer Science ya SB RAS.
Mu positi iyi ndikufuna ndikuuzeni zomwe zidabwera pa lingaliro loyambitsa maphunziro a makina kwa ophunzira, omaliza maphunziro a Novosibirsk State University ndi wina aliyense.
Ndakhala ndikufuna kukonza maphunziro apadera pokonzekera mipikisano yosanthula deta pa Kaggle ndi nsanja zina. Ili likuwoneka ngati lingaliro labwino:
- Ophunzira ndi aliyense amene ali ndi chidwi adzagwiritsa ntchito chidziwitso chaukadaulo pochita ndikupeza luso lothana ndi mavuto pamipikisano yapagulu.
- Ophunzira omwe amakhala pamwamba pamipikisano yotere amakhala ndi zotsatira zabwino pa kukopa kwa NSU kwa ofunsira, ophunzira ndi omaliza maphunziro. Zomwezo zimachitika ndi maphunziro a mapulogalamu a masewera.
- Maphunziro apaderawa amakwaniritsa bwino komanso amakulitsa chidziwitso chofunikira: otenga nawo mbali pawokha amakhazikitsa njira zophunzirira zamakina ndipo nthawi zambiri amapanga magulu omwe amapikisana pamlingo wapadziko lonse lapansi.
- Mayunivesite ena anali atachita kale maphunziro oterowo, chotero ndinali ndi chiyembekezo cha kupambana kwa kosi yapadera ya NSU.
Yambitsani
Akademgorodok wa Novosibirsk ali ndi nthaka yachonde kwambiri pazochita zotere: ophunzira, omaliza maphunziro ndi aphunzitsi a Computer Science Center ndi luso lamphamvu, mwachitsanzo, FIT, MMF, FF, chithandizo champhamvu cha utsogoleri wa NSU, gulu logwira ntchito la ODS, akatswiri odziwa zambiri. ndi akatswiri ochokera kumakampani osiyanasiyana a IT. Pa nthawi yomweyo, tinaphunzira za pulogalamu thandizo kuchokera - thumba limathandizira magulu omwe amawonetsa zotsatira zabwino pamipikisano yamasewera a ML.
Tidapeza omvera ku NSU pamisonkhano yamlungu ndi mlungu, tidapanga macheza pa Telegalamu, ndikuyambitsa pa Okutobala 1 pamodzi ndi ophunzira ndi omaliza maphunziro a CS Center. Anthu 19 anabwera ku phunziro loyamba. Anthu asanu ndi mmodzi a iwo anakhala ochita nawo maphunziro nthaΕ΅i zonse. Onse pamodzi, anthu 31 anabwera kumsonkhano kamodzi kokha mβchaka cha maphunziro.
Zotsatira zoyamba
Anyamatawo ndi ine tinakumana, tinasinthana zochitika, tinakambirana za mpikisano ndi ndondomeko yovuta ya tsogolo. Mwamsanga tinazindikira kuti kumenyera malo pamipikisano yosanthula deta ndi ntchito yanthawi zonse, yotopetsa, yofanana ndi ntchito yosalipidwa yanthawi zonse, koma yosangalatsa komanso yosangalatsa π Mmodzi mwa omwe adatenga nawo gawo, Kaggle-master Maxim, adatilangiza kuti tipite patsogolo pamipikisano payekhapayekha. , ndipo masabata angapo pambuyo pake amalumikizana kukhala magulu, poganizira zomwe anthu apeza. Ndi zomwe tinachita! Pakuphunzitsidwa pamasom'pamaso, tidakambirana zitsanzo, zolemba zasayansi, ndi zovuta za malaibulale a Python, ndikuthetsa mavuto pamodzi.
Zotsatira za semester yakugwa zinali mendulo zasiliva zitatu pamipikisano iwiri pa Kaggle: ΠΈ . Ndipo gawo limodzi mwa magawo atatu mu mpikisano wa CFT wowongolera typos ndi ndalama zoyamba zomwe zidapambana (mu ndalama, monga momwe keglers odziwa bwino amanenera).
Chotsatira china chofunikira kwambiri chosalunjika cha maphunziro apadera chinali kukhazikitsa ndikusintha gulu la NSU VKI. Mphamvu zake zamakompyuta zasintha kwambiri moyo wathu wampikisano: 40 CPUs, 755Gb RAM, 8 NVIDIA Tesla V100 GPUs.
Izi zisanachitike, tidapulumuka momwe tingathere: tidawerengera ma laputopu ndi ma desktops, mu Google Colab ndi mu Kaggle-kernels. Gulu limodzi linali ndi zolemba zodzilemba zokha zomwe zidasunga zokha chitsanzocho ndikuyambiranso kuwerengera komwe kudayima chifukwa chanthawi yayitali.
Mu semester ya masika, tinapitiliza kusonkhana, kusinthanitsa zomwe tapeza bwino ndikukambirana za njira zothetsera mpikisano. Ochita nawo chidwi atsopano anayamba kubwera kwa ife. Mu semester ya masika, tinakwanitsa kutenga golide mmodzi, siliva atatu ndi bronze asanu ndi anayi m'mipikisano isanu ndi itatu pa Kaggle: , , , , , ndi ena, mkuwa mkati , malo achitatu ku Changellenge>>Mpikisano ndi malo oyamba (kachiwiri mu ndalama) mu mpikisano wophunzirira makina pa kuchokera ku Yandex.
Zomwe ophunzira anena
"Ndili wokondwa kwambiri kuti ntchito zoterezi zikuchitika kuno ku Siberia, chifukwa ndikukhulupirira kuti kutenga nawo mbali mu mpikisano ndiyo njira yachangu yophunzirira ML. Pamipikisano yotereyi, zida za Hardware ndizokwera mtengo kudzigula, koma apa mutha kuyesa malingaliro kwaulere. β
"Asanabwere maphunziro a ML, sindinkachita nawo mipikisano makamaka kupatula maphunziro ndi mipikisano yachihindu: Sindinawone tanthauzo la izi, popeza ndinali ndi ntchito ku ML, ndipo ndimalidziwa. Semesita yoyamba yomwe ndinaphunzirapo ndili wophunzira. Ndipo kuyambira semester yachiwiri, zida zamakompyuta zitangopezeka, ndimaganiza, bwanji osatenga nawo gawo. Ndipo zinandikokera. Ntchito, deta ndi ma metrics adapangidwa ndikukukonzerani inu, pitirirani ndikugwiritsa ntchito mphamvu zonse za MO, fufuzani zitsanzo zamakono ndi zamakono. Pakadapanda maphunzirowo ndipo, chofunikira kwambiri, zida zamakompyuta, sindikanayamba kuchita nawo posachedwa. β
"Maphunziro a ML mwa munthu adandithandiza kupeza anthu amalingaliro ofanana, omwe ndidatha kukulitsa chidziwitso changa pakuphunzira makina ndi kusanthula deta. Iyinso ndi njira yabwino kwambiri kwa iwo omwe alibe nthawi yochulukirapo yodzisanthula okha ndikukhazikika pamutu wamipikisano, komabe akufuna kukhala pamutuwu. β
titsatireni
Mipikisano pa Kaggle ndi nsanja zina zimakulitsa luso lothandizira ndikusinthira mwachangu kukhala ntchito yosangalatsa pankhani ya sayansi ya data. Anthu omwe atenga nawo mbali mu mpikisano wovuta pamodzi nthawi zambiri amakhala ogwira nawo ntchito ndikupitirizabe kuthetsa mavuto okhudzana ndi ntchito. Izi zinatichitikiranso: Mikhail Karchevsky, pamodzi ndi bwenzi la gululo, anapita kukagwira ntchito ku kampani yomweyi pa ndondomeko yovomerezeka.
Pakapita nthawi, tikukonzekera kukulitsa ntchitoyi ndi zofalitsa zasayansi komanso kutenga nawo mbali pamisonkhano yophunzirira makina. Lowani nafe monga otenga nawo mbali kapena akatswiri ku Novosibirsk - lembani kapena . Konzani maphunziro ofanana m'mizinda ndi mayunivesite anu.
Nali tsamba lachinyengo lokuthandizani kuchitapo kanthu koyamba:
- Ganizirani za malo abwino ndi nthawi yochitira makalasi okhazikika. Mulingo woyenera - 1-2 pa sabata.
- Lemberani anthu omwe angakhale achidwi za msonkhano woyamba. Choyamba, awa ndi ophunzira a mayunivesite aukadaulo, otenga nawo gawo pa ODS.
- Yambitsani kucheza kuti mukambirane zomwe zikuchitika: Telegalamu, VK, WhatsApp kapena mesenjala wina aliyense wosavuta kwa ambiri.
- Pitirizani kukhala ndi dongosolo la maphunziro lomwe anthu angapeze, mndandanda wa mpikisano ndi omwe atenga nawo mbali, ndikuwunika zotsatira.
- Pezani mphamvu zamakompyuta zaulere kapena zopereka zake m'mayunivesite apafupi, mabungwe ofufuza kapena makampani.
- ZIMENE MUNGACHITE!
