Amagama ambalwa mayelana nama-Olympics
Injongo. Hlola ulwazi lwabafundi futhi ubethule ezidingweni zabaqashi. Abafundi bathuthuka emkhakheni wabo wesayensi abawukhethile, basebenza ezinkampanini zamazwe ngamazwe. Umqashi naye uyahlomula - akadingi ukuthi aphinde abhalise ochwepheshe abaqeqeshiwe futhi abingelele izisebenzi ezisanda kuqashwa ngegama elithi: “Khohlwa konke owakufundiswa enyuvesi.”
Kungani uhlanganyela? Abawinile ngena emanyuvesi aseRussia ngaphandle kwezivivinyo. Ungathola i-internship e-Yandex, Sberbank, IBS, Mail.ru nezinye izinkampani ezinkulu. Ngonyaka odlule, izipesheli ezivela ezinkampanini zaseRussia abangaphezu kwamakhulu amane ababambiqhaza abahamba phambili. Futhi, abafundi abazibonakalise bazokwazi ukuvakashela .
Ubani obambe iqhaza? Abafundi bazo zonke izici - technical, humanities kanye nesayensi yemvelo. Ngaphezu kwabathweswe iziqu, abafundi abaneziqu, izakhamuzi kanye nabafundi bamanyuvesi angaphandle.
Ifomethi yomcimbi. Ungabhalisa kuze kube nguNovemba 18. Isigaba sokufaneleka esiku-inthanethi sizokwenzeka kusukela ngoNovemba 22 kuya kuDisemba 8, kodwa ungakwazi ukweqa uma uqedele okungenani okubili ngempumelelo. . Abaphumelele umzuliswano wokuhlunga bazodlulela emiqhudelwaneni ye-intramural emanyuvesi amakhulu ezweni lonke, ehlelelwe uJanuwari - Mashi. Imiphumela ye-Olympiad ethi “I am a Professional” izoshicilelwa ngo-April .
Kulo nyaka i-Olympiad ihlanganisa izindawo ezingu-68. Ochwepheshe beNyuvesi ye-ITMO baqondisa abahlanu kubo: “Ama-Photonics”, “Imininingwane kanye Nezokuphepha Ze-Cyber”, “Ubuchwepheshe Bokuhlela Nokwaziswa”, kanye “Nedatha Enkulu” kanye “Ne-Robotics”. Sizokutshela kabanzi mayelana nalezi ezimbili zokugcina.
Idatha Enkulu
Le ndawo ihlanganisa bonke ubuchwepheshe bomjikelezo wempilo Yedatha Enkulu, okuhlanganisa ukuqoqwa kwayo, ukugcinwa, ukucubungula, ukumodela nokutolika. Abaphumelele bazokwazi ukungena ohlelweni lwe-masters eNyuvesi ye-ITMO ngaphandle kwezivivinyo zezinhlelo: “Applied Mathematics and Informatics”, “Digital Health”, “Big Data Financial Technologies” kanye .
Abahlanganyeli bazothola nethuba lokufundela amakhono ososayensi bedatha kanye nonjiniyela wedatha ezinkampanini ezisebenzisana nabo. Lezi yiNational Center for Cognitive Research, Mail.ru, Gazpromneft STC, Rosneft, Sberbank kanye ne-ER-Telecom.
“Eminyakeni yakamuva, umkhakha weBig Data usuthandwa kakhulu. Ubuchwepheshe bokuqoqwa kwedatha eyisisekelo nokugcinwa buyathuthuka, izindlela ezintsha zedijithali ziyavela (emkhakheni we-IoT nezinkundla zokuxhumana) zokurekhoda izinqubo ebezingabonwa ngaphambilini,” kuphawula u-Alexander Valerievich Bukhanovsky, umqondisi. ITMO University. "Ngasikhathi sinye, akunakwa nje kuphela ukuthi ihlelwa kanjani inqubo yokugcina nokusebenzisa idatha, kodwa futhi nokuqinisekisa iziphetho nezinqumo, kanye nokudala amamodeli abikezelayo."
Izoba yini imisebenzi? Iqembu liyabalungiselela ITMO University. Bacabangela iqiniso lokuthi uchwepheshe Wedatha Enkulu kufanele abe nolwazi oluyisisekelo kuthiyori yamathuba nezibalo zezibalo, kanye nokufunda komshini. Yiba nokuqonda okunengqondo kanye nendlela yokusebenza yezinhlelo zesimanje zobuhlakani bokwenziwa futhi ukhulume isi-R, Java, Scala, Python (noma amanye amathuluzi okuxazulula izinkinga ezingokoqobo).
Ngezansi sinikeza isibonelo senkinga evela kwesinye sezigaba ze-Olympiad.
Isibonelo somsebenzi: Kunamaseva angama-50 kuqoqo, anama-cores ayi-12 atholakalayo kuqoqo ngalinye. Izinsiza phakathi kwamamephu nabanciphisi zabiwa kabusha ngokushintshashintsha (akukho kuhlukaniswa okuqinile kwezisetshenziswa). Bhala ukuthi mingaki imizuzu umsebenzi we-MapNcisa odinga amamephu ayi-1000 uzosebenza kuqoqo elinjalo. Kulokhu, isikhathi sokusebenza semephu eyodwa imizuzu engama-20. Uma ushiya isinciphisi esingu-1 kuphela emsebenzini, sizocubungula yonke idatha ngemizuzu eyi-1000. Impendulo yamukelwa inembile endaweni eyodwa yedesimali.

Indlela yokulungiselela. Ungaqala ngezinsiza ezilandelayo:
- . Kungaba usizo emsebenzini ozimele onamakhodi omthombo wokuxazulula izinkinga.
- . Umsebenzi oyisisekelo utshela ukuthi kungani amamodeli angenzeka adinga ukwakhiwa kwezibalo njengokuthi σ-algebra.
- . Incwadi elula newusizo eveza izisekelo zokubala okungenzeka kwezehlakalo ezingahleliwe.
Amabhuku amaningana atholakalayo ngezibalo ezisetshenzisiwe zemikhakha ehlukahlukene yomsebenzi. Ababhali bawo bawuchaza kalula kodwa ngempumelelo umcabango wokuxazulula izinkinga zephuzu kanye nesilinganiso sekhefu:
Izinkomba
Ulwazi lungatholakala nasezifundweni ezinezihloko kuwebhusayithi yama-Olympics.
Amarobhothi
Amarobhothi ahlanganisa imikhakha efana ne-algorithms, i-electronics kanye nemishini. Lesi siqondiso kufanele sikhethelwe labo asebevele befunda noma balungiselela ukungena ezinhlelweni ze-master kanye neziqu zobunjiniyela besoftware, i-application mechanics, i-application mathematics ne-computer science noma ubunjiniyela be-elekthronikhi. Abafundi abafakazelwe bangabhalisa ezinhlelweni mahhala "",""Futhi""enyuvesi yethu.
Izoba yini imisebenzi? Abafundi be-Master's kanye ne-bachelor's baxazulula imisebenzi ehlukene. Kodwa-ke, yonke imisebenzi ihlola ulwazi oluyinkimbinkimbi lwethiyori yokulawula, ukucubungula ulwazi kanye nokumodela kwamarobhothi. Isibonelo, ababambiqhaza bazocelwa ukuthi bahlole ukuzinza noma ukulawuleka kwesistimu, bakhethe isakhiwo, noma babale ama-coefficients wesilawuli.
"Kuzodingeka sixazulule inkinga ye-kinematics eqondile noma ephambene yerobhothi ephathwayo noma ekhohlisayo, sisebenze ne-Jacobian yohlelo futhi sibheke izikhathi zokulinganisa emajoyini ngaphansi komthwalo wangaphandle onikeziwe," kusho uSergey Alekseevich Kolyubin, isekela lomqondisi. e-ITMO. "Kuzoba nemisebenzi yokuhlela - udinga ukubhala uhlelo oluncane lokumodela irobhothi noma ukuhlela ama-trajectories ngePython noma C++."
Ekugcineni, abafundi kufanele bahlele irobhothi ukwenza imisebenzi evela ezinkampanini ezisebenzisana nabo: I-Russian Railways, i-Diakkont, i-KUKA, njll. Amaphrojekthi ahlobene nama-drones omhlaba nomoya, kanye namarobhothi asebenzisanayo asebenza ezimeni zokuthintana ngokomzimba imvelo. Ifomethi yomncintiswano iyafana . Okokuqala, abafundi basebenza kusifanisi, bese kuba ngehardware yangempela.
Okulandelayo, sizocubungula izinketho ezimbalwa zemisebenzi emkhakheni wamarobhothi abafundi abangase bahlangabezane nayo. Nazi izibonelo zabenzi bezicelo ezinhlelweni zenkosi:
Isibonelo somsebenzi #1: Irobhothi le-automotive kinematics lihamba ngesivinini somugqa v=0,3 m/s. Isondo lokuqondisa liphendulwa nge-engeli w=0,2 rad. Uma irediyasi yamasondo erobhothi ilingana no-r=0,02 m, futhi ubude nethrekhi yerobhothi ilingana no-L=0,3 m no-d=0,2 m, ngokulandelana, azoba yini ama-angular esondo ngalinye langemuva i-w1 kanye ne-w2, evezwe nge-rad/s?
Faka impendulo yakho ngefomethi yezinombolo ezimbili ezihlukaniswe yisikhala, ezinembile endaweni yesibili yedesimali, ucabangela uphawu.Isibonelo somsebenzi #2: Kungaba yini isibonakaliso se-astatism ohlelweni oluvaliwe oluhlobene nomthelela wereferensi, uma ukuhlaziywa kwenziwa ngokuvumelana nomdwebo wesakhiwo sesistimu?
ukuba khona kwezixhumanisi ze-aperiodic endaweni evulekile;
ukuba khona kwezixhumanisi ezinhle zokuhlanganisa ku-loop evulekile;
ukuba khona kwezixhumanisi ze-oscillatory kanye ne-conservative endaweni evulekile.
Nazi izinkinga zalabo abangena esikoleni esiphakeme noma indawo yokuhlala:
Isibonelo somsebenzi #1: Isibalo sibonisa i-robotic manipulator enama-kinematics angasebenzi anamalunga angu-7 ajikelezayo. Isibalo sibonisa isistimu ye-robot ye-coordinate {s} ene-y-axis vector perpendicular to the plane yekhasi, isistimu yokuxhumanisa {b} exhunywe ku-flange kanye ne-collinear ngokuthi {s}. Irobhothi liboniswa ekucushweni lapho izixhumanisi ze-angular zazo zonke izixhumanisi zilingana no-0. Izimbazo ze-helical zamapheya e-kinematic ayisikhombisa aboniswa esithombeni (inkomba eqondile ephikisana newashi). Izimbazo zamajoyinti 2, 4 no-6 ziqondiswe ngokubambisana, izimbazo zamajoyinti 1, 3 5 no-7 zifana nezimbazo zesistimu yokuxhumanisa yokuqala yesisekelo. Osayizi bezixhumanisi L1 = 0,34 m, L2 = 0,4 m, L3 = 0,4 m, futhi L4 = 0,15 m.
Isibonelo somsebenzi #2: Ukuze uthole ukusebenza okuzinzile kwe-algorithm ngesikhathi esisodwa sokwenza indawo kanye nokumepha (i-SLAM) yamarobhothi eselula asuselwa kuzihlungi zezinhlayiyana, onjiniyela banqume ukusebenzisa i-algorithm yokusampling yesondo kabusha. Esikhathini esithile ekusebenzeni kwe-algorithm, isampula "yezinhlayiya" ezingu-5 ezinesisindo w(1) = 0,5, w(2) = 1,2, w(3) = 1,5, w(4) = 1,0 yahlala enkumbulweni. 5 kanye ne-w(0,8) = XNUMX. Ingakanani i-threshold value encane yosayizi wesampula osebenzayo ekuphindaphindeni okuthile lapho kuzoqaliswa indlela yokusampula kabusha. Bhala impendulo yakho ngefomethi yedesimali enembile endaweni eyodwa yedesimali.
Indlela yokulungiselela. Ungakwazi ukuhlola ulwazi lwakho namathemba ngokusebenzisa uhlu lokuhlola. Ababambiqhaza kumaRobhothi amakhulu kumele:
- Yazi izimiso zokumodela irobhothi, izici zezinzwa zesimanje nezindlela zokuthola ulwazi lwezinzwa.
