Igama lam ndinguSasha kwaye ndiyakuthanda ukufunda ngoomatshini kunye nokufundisa abantu. Ngoku ndilawula iinkqubo zemfundo kwiZiko leNzululwazi yeKhompyutha kwaye ndiqondise inkqubo ye-bachelor kuhlalutyo lwedatha kwiYunivesithi yaseSt. Ngaphambi koko, wasebenza njengomhlalutyi eYandex, kwaye nangaphambili njengososayensi: wayesebenza kwimodeli yezibalo kwiZiko leSayensi yeKhompyutha yeSB RAS.
Kule post ndifuna ukukuxelela into eza ngombono wokuqaliswa koqeqesho lokufunda koomatshini kubafundi, abaphumelele kwiYunivesithi yaseNovosibirsk State kunye naye wonke umntu.
Kudala ndifuna ukuququzelela ikhosi ekhethekileyo yokulungiselela ukhuphiswano lokuhlalutya idatha kwiKaggle kunye namanye amaqonga. Oku kwakubonakala ngathi licebo elihle:
- Abafundi kunye nabani na onomdla baya kusebenzisa ulwazi lwethiyori ekusebenzeni kwaye bafumane amava ekusombululeni iingxaki kukhuphiswano loluntu.
- Abafundi abagqwesileyo kukhuphiswano olunjalo banefuthe elihle kumtsalane we-NSU kubafaki-zicelo, abafundi kunye nabaphumeleleyo. Kwenzeka into efanayo ngoqeqesho lwenkqubo yezemidlalo.
- Le khosi ikhethekileyo izalisekisa ngokugqibeleleyo kwaye yandisa ulwazi olusisiseko: abathathi-nxaxheba baphumeza ngokuzimeleyo imodeli yokufunda koomatshini kwaye bahlala bejoyina amaqela akhuphisanayo kwinqanaba lehlabathi.
- Ezinye iiyunivesithi zazisele ziluqhube olo qeqesho, ngoko ndandinethemba lokuphumelela kwesi sifundo sikhethekileyo saseNSU.
Qalisa
I-Akademgorodok yaseNovosibirsk inomhlaba ochume kakhulu kwimigudu enjalo: abafundi, abaphumeleleyo kunye nootitshala beZiko leSayensi yeKhompyutha kunye nezakhono ezinamandla zobugcisa, umzekelo, i-FIT, i-MMF, i-FF, inkxaso eqinile yolawulo lwe-NSU, uluntu olusebenzayo lwe-ODS, iinjineli ezinamava. kunye nabahlalutyi abavela kwiinkampani ezahlukeneyo ze-IT. Kwangelo xesha linye, safunda ngenkqubo yesibonelelo - ingxowa-mali ixhasa amaqela abonisa iziphumo ezilungileyo kukhuphiswano lwezemidlalo lweML.
Sifumene abaphulaphuli kwi-NSU kwiintlanganiso zeveki, senze incoko kwiTelegram, kwaye yasungulwa ngo-Okthobha woku-1 kunye nabafundi kunye nabaphumelele kwiziko le-CS. Abantu abali-19 beza kwisifundo sokuqala. Abathandathu kubo baba nenxaxheba rhoqo kuqeqesho. Bebonke, abantu abangama-31 beza entlanganisweni ubuncinane kube kanye ngexesha lonyaka wokufunda.
Iziphumo zokuqala
Abafana kunye nam sadibana, satshintshiselana ngamava, saxoxa ngokhuphiswano kunye nesicwangciso esibi sekamva. Ngokukhawuleza safumanisa ukuba ukulwela iindawo kukhuphiswano lokuhlalutya idatha ngumsebenzi oqhelekileyo, onzima, ofana nomsebenzi osisigxina ongahlawulwayo, kodwa unomdla kakhulu kwaye unika umdla π Omnye wabathathi-nxaxheba, uKaggle-master Maxim, usicebise ukuba siqhubele phambili kukhuphiswano ngamnye , kwaye emva kweeveki ezimbalwa emva koko bahlangane babe ngamaqela, kuthathelwa ingqalelo amanqaku kawonkewonke. Yiloo nto esayenzayo! Ngexesha loqeqesho lobuso ngobuso, siye saxoxa ngemizekelo, amanqaku enzululwazi, kunye nobugocigoci bamathala eencwadi ePython, saza sacombulula iingxaki kunye.
Iziphumo zesiqingatha sonyaka zaziziimbasa ezintathu zesilivere kukhuphiswano olubini eKaggle: ΠΈ . Kwaye indawo yesithathu kukhuphiswano lweCFT yokulungisa iitypos kunye nemali yokuqala ephumeleleyo (ngemali, njengoko i-keglers enamava ithi).
Esinye isiphumo esibaluleke kakhulu esingathanga ngqo sekhosi ekhethekileyo yayikukusungulwa kunye nokucwangciswa kweqela le-NSU VKI. Amandla ayo ekhompyutheni aphucule kakhulu ubomi bethu obukhuphisanayo: 40 CPUs, 755Gb RAM, 8 NVIDIA Tesla V100 GPUs.
Ngaphambi koko, siphile kangangoko sinako: sibale kwiilaptops zobuqu kunye needesktops, kuGoogle Colab nakwiKaggle-kernels. Elinye iqela lide libe nescript esizibhalayo esigcine ngokuzenzekelayo imodeli kwaye saphinda saqalisa ukubala obekuyekile ngenxa yomda wexesha.
Kwisemester yasentwasahlobo, saqhubeka siqokelelana, sitshintshiselana ngeziphumo eziyimpumelelo kwaye sithethe ngezisombululo zethu kukhuphiswano. Abathathi-nxaxheba abatsha abanomdla baqalisa ukuza kuthi. Ngexesha lesemester yasentwasahlobo, sikwazile ukuthatha igolide enye, isilivere ezintathu kunye nobhedu olusithoba kukhuphiswano olusibhozo eKaggle: , , , , , abanye ke belubhedu , indawo yesithathu kwi-Changellenge>>Indebe kunye nendawo yokuqala (kwakhona kwimali) kukhuphiswano lokufunda ngomatshini e. ukusuka kwiYandex.
Bathini abathathi-nxaxheba boqeqesho
"Ndiyavuya kakhulu ukuba imisebenzi enjalo yenziwa apha eSiberia, kuba ndikholelwa ukuba ukuthatha inxaxheba kukhuphiswano yeyona ndlela ikhawulezayo yokuqonda iML. Kukhuphiswano olunjalo, i-hardware ibiza kakhulu ukuzithenga, kodwa apha ungazama izimvo simahla.
βNgaphambi kokufika koqeqesho lwe-ML, andizange ndithathe inxaxheba ngokukodwa kukhuphiswano ngaphandle koqeqesho nokhuphiswano lwamaHindu: Andizange ndibone ngongoma kule nto, kuba ndandinomsebenzi kwicandelo leML, kwaye ndandiqhelene nalo. Isiqingatha sonyaka wokuqala ndaya esikolweni. Kwaye ukuqala kwi-semester yesibini, nje ukuba izixhobo zekhompyuter zifumaneke, ndacinga ukuba kutheni ungathabathi nxaxheba. Kwaye yandidibanisa. Umsebenzi, idatha kunye neemetrics zaqanjwa kwaye zalungiselelwa wena, qhubeka kwaye usebenzise amandla apheleleyo e-MO, khangela iimodeli ze-state-of-art kunye nobuchule. Ukuba bekungeloqeqesho kwaye, ngokubaluleke kakhulu, izixhobo zekhompyuter, ngendingazange ndiqalise ukuthatha inxaxheba kwakamsinyane. "
"Uqeqesho lwe-ML lwangaphakathi lwandinceda ukuba ndifumane abantu abanengqondo efanayo, endiye ndakwazi ukuqinisa ulwazi lwam kwinkalo yokufunda koomatshini kunye nohlalutyo lwedatha. Olu lolona khetho lubalaseleyo kwabo bangenaxesha lasimahla lokuzihlalutya ngokuzimeleyo kwaye bazijulele kwisihloko sokhuphiswano, kodwa basafuna ukuba sesihloko. β
dibana nathi
Ukhuphiswano kwiKaggle kunye namanye amaqonga aphucula izakhono ezisebenzayo kwaye aguqule ngokukhawuleza abe ngumsebenzi onomdla kwicandelo lesayensi yedatha. Abantu abaye bathatha inxaxheba kukhuphiswano olunzima kunye bavame ukuba ngabalingane kwaye baqhubeke nokusombulula ngempumelelo iingxaki ezinxulumene nomsebenzi. Oku kwenzeka nakuthi: uMikhail Karchevsky, kunye nomhlobo weqela, baya kusebenza kwinkampani efanayo kwinkqubo yokucebisa.
Ngokuhamba kwexesha, siceba ukwandisa lo msebenzi kunye neempapasho zesayensi kunye nokuthatha inxaxheba kwiinkomfa zokufunda ngomatshini. Sijoyine njengabathathi-nxaxheba okanye iingcali eNovosibirsk - bhala okanye . Lungiselela uqeqesho olufanayo kwizixeko zakho nakwiiyunivesithi.
Nali icwecwe elincinci lokukunceda uthathe amanyathelo akho okuqala:
- Cinga indawo efanelekileyo kunye nexesha leeklasi eziqhelekileyo. Ngokufanelekileyo - 1-2 amaxesha ngeveki.
- Bhalela abathathi-nxaxheba abanokuba nomdla malunga nentlanganiso yokuqala. Okokuqala, aba ngabafundi beeyunivesithi zobugcisa, abathathi-nxaxheba be-ODS.
- Qala incoko ukuze uxoxe ngemicimbi yangoku: ITelegram, iVK, iWhatsApp okanye nasiphi na esinye isithunywa esilungele uninzi.
- Gcina isicwangciso sesifundo esifikelelekayo esidlangalaleni, uluhlu lokhuphiswano kunye nabathathi-nxaxheba, kwaye ubeke iliso kwiziphumo.
- Fumana amandla ekhompyuter simahla okanye izibonelelo zayo kwiiyunivesithi ezikufutshane, amaziko ophando okanye iinkampani.
- INZUZO!
