4. Ikhwalithi yokuhlanza idatha
Ikhwalithi yokuhlanza idatha iyinkinga eyinkinga ku-bigdata. Ukuphendula umbuzo wokuthi yiliphi izinga lokuhlanzwa kwedatha elidingekayo ukuze uqedele umsebenzi kubalulekile kuwo wonke umhlaziyi wedatha. Ezinkingeni eziningi zamanje, umhlaziyi ngamunye unquma lokhu ngokwakhe futhi akunakwenzeka ukuthi noma ubani ovela ngaphandle akwazi ukuhlola lesi sici esixazululweni sakhe. Kodwa ngomsebenzi owenziwa kuleli cala, lolu daba lwalubaluleke kakhulu, ngoba ukwethembeka kwedatha yezomthetho kufanele kuthambekele kokukodwa.
Kucatshangelwa ubuchwepheshe bokuhlola isoftware ukuze kutholwe ukwethembeka kokusebenza. Namuhla kukhona okungaphezu kwalezi zinhlobo . Iningi lamamodeli lisebenzisa imodeli yesevisi yesimangalo:
U-fig. 6
Ukucabanga ngale ndlela: "Uma iphutha elitholakele liwumcimbi ofana nesehlo sokungaphumeleli kule modeli, ungayithola kanjani i-analogue yepharamitha t?" Futhi ngahlanganisa imodeli elandelayo: Ake sicabange ukuthi isikhathi esithatha umhloli ukuhlola irekhodi elilodwa iminithi elingu-1 (kusizindalwazi okukhulunywa ngaso), bese sithola wonke amaphutha azowadinga imizuzu engu-365, okungaba iminyaka emi-494 kanye ne-3. izinyanga zesikhathi sokusebenza. Njengoba siqonda, leli inani elikhulu kakhulu lomsebenzi futhi izindleko zokuhlola isizindalwazi zizokwenqabela kumdidiyeli wale database. Kulo mbono, umqondo wezomnotho wezindleko uyavela futhi ngemva kokuhlaziya ngifinyelele esiphethweni sokuthi leli ithuluzi elisebenza kahle. Ngokusekelwe emthethweni wezomnotho: “Ivolumu yokukhiqiza (ngamayunithi) lapho kufinyelelwa khona inzuzo enkulu yenkampani itholakala endaweni lapho izindleko ezinqenqemeni zokukhiqiza iyunithi entsha yomkhiqizo ziqhathaniswa nenani le nkampani engayithola. kuyunithi entsha. " Ngokusekelwe esimisweni sokuthi ukuthola iphutha ngalinye elilandelayo kudinga ukuhlolwa okwengeziwe kwamarekhodi, lokhu kuyisici sezindleko. Okusho ukuthi, i-postulate eyamukelwe kumamodeli wokuhlola ithatha incazelo engokoqobo kuphethini elandelayo: uma ukuthola iphutha le-i-th kwakudingeka ukuhlola amarekhodi n, khona-ke ukuthola iphutha elilandelayo (i+3) kuzodingeka. ukuhlola amarekhodi m futhi ngesikhathi esifanayo n
- Lapho inani lamarekhodi ahloliwe ngaphambi kokuba kutholakale iphutha elisha lizinza;
- Lapho inani lamarekhodi ahloliwe ngaphambi kokuthola iphutha elilandelayo lizokhula.
Ukuze nginqume inani elibucayi, ngaphendukela emcabangweni wokuba nokwenzeka kwezomnotho, okuthi kulokhu, kusetshenziswa umqondo wezindleko zokuxhumana nabantu, kungenziwa kanje: “Izindleko zokulungisa iphutha kufanele zithwalwe yi-ejenti yezomnotho engakwazi ukuyenza. ngenani eliphansi kakhulu.” Sinomenzeli oyedwa - umhloli ochitha iminithi elingu-1 ehlola irekhodi elilodwa. Ngokwezimali, uma uhola ama-ruble angu-6000/ngosuku, lokhu kuzoba ama-ruble angu-12,2. (cishe namuhla). Kusele ukunquma uhlangothi lwesibili lokulingana emthethweni wezomnotho. Ngacabanga kanje. Iphutha elikhona lizodinga ukuthi umuntu othintekayo enze umzamo wokulilungisa, okungukuthi, umnikazi wendawo. Ake sithi lokhu kudinga usuku olungu-1 lwesenzo (hambisa isicelo, thola idokhumenti elungisiwe). Khona-ke, ngokombono womphakathi, izindleko zakhe zizolingana nomholo ojwayelekile ngosuku. Iholo elimaphakathi elinqwabelene e-Khanty-Mansi Autonomous Okrug 73285 rub. noma ama-ruble angama-3053,542/ngosuku. Ngokuvumelana nalokho, sithola inani elibalulekile elilingana ne:
3053,542: 12,2 = 250,4 amayunithi amarekhodi.
Lokhu kusho ukuthi, ngokombono womphakathi, uma umhloli ehlole amarekhodi angama-251 futhi wathola iphutha elilodwa, kulingana nomsebenzisi olungisa leli phutha ngokwakhe. Ngakho-ke, uma umhloli echithe isikhathi esilingana nokuhlola amarekhodi angama-252 ukuze athole iphutha elilandelayo, khona-ke kulokhu kungcono ukushintsha izindleko zokulungisa kumsebenzisi.
Indlela elula inikezwa lapha, kusukela ekubukeni komphakathi kuyadingeka ukucabangela lonke inani elengeziwe elikhiqizwa uchwepheshe ngamunye, okungukuthi, izindleko ezihlanganisa izintela kanye nezinkokhelo zomphakathi, kodwa imodeli icacile. Umphumela walobu budlelwano yilokhu okudingekayo okulandelayo kochwepheshe: uchwepheshe ovela embonini ye-IT kufanele abe nomholo omkhulu kunesilinganiso sikazwelonke. Uma umholo wakhe ungaphansi kwesilinganiso somholo wabasebenzisi abangaba be-database, yena ngokwakhe kufanele ahlole yonke imininingwane yedatha ngesandla.
Lapho usebenzisa umbandela ochaziwe, imfuneko yokuqala yekhwalithi yedatha yakhiwe:
I(tr). Isabelo samaphutha abucayi akufanele sidlule i-1/250,4 = 0,39938%. Kancane kancane kunalokho igolide embonini. Futhi ngokwezinto ezibonakalayo awekho amarekhodi angaphezu kuka-1459 anamaphutha.
Ukuhlehla kwezomnotho.
Eqinisweni, ngokwenza inani elinjalo lamaphutha kumarekhodi, umphakathi uvumelana nokulahlekelwa kwezomnotho ngenani:
1459 * 3053,542 = 4 ruble.
Lesi samba sinqunywa ukuthi umphakathi awunawo amathuluzi okunciphisa lezi zindleko. Lokhu kulandela ukuthi uma othile enobuchwepheshe obumvumela ukuthi anciphise inani lamarekhodi anamaphutha, ngokwesibonelo, 259, khona-ke lokhu kuzovumela umphakathi ukuthi ulondoloze:
1200 * 3053,542 = 3 ruble.
Kodwa ngesikhathi esifanayo, angacela ithalente lakhe nomsebenzi, ake sithi - ruble ayizigidi ezingu-1.
Okungukuthi, izindleko zomphakathi zehliswa ngokuthi:
3 - 664 = 250 ruble.
Empeleni, lo mphumela uyinani elingeziwe elivela ekusetshenzisweni kobuchwepheshe be-BigDat.
Kodwa lapha kufanele kucatshangelwe ukuthi lokhu kuwumphumela wezenhlalakahle, futhi umnikazi we-database yiziphathimandla zikamasipala, imali engenayo evela ekusetshenzisweni kwempahla erekhodiwe kule database, ngesilinganiso se-0,3%, yi: 2,778 billion ruble / unyaka. Futhi lezi zindleko (ama-ruble angu-4) azimkhathazi kangako, ngoba zidluliselwa kubanikazi bezakhiwo. Futhi, kulesi sici, umthuthukisi wobuchwepheshe bokucwenga okwengeziwe ku-Bigdata kuzodingeka abonise ikhono lokukholisa umnikazi wale database, futhi izinto ezinjalo zidinga ithalente elikhulu.
Kulesi sibonelo, i-algorithm yokuhlola iphutha ikhethwe ngokusekelwe kumodeli ye-Schumann [2] yokuqinisekiswa kwesofthiwe phakathi nokuhlolwa kokwethembeka. Ngenxa yokusabalala kwayo ku-inthanethi kanye nekhono lokuthola izinkomba zezibalo ezidingekayo. Indlela yokusebenza ithathwe eMonakhov Yu.M. "Ukuzinza okusebenzayo kwezinhlelo zolwazi", bheka ngaphansi kwe-spoiler ku-Fig. 7-9.
Ilayisi. 7 – 9 Indlela yokwenza yemodeli ye-Schumann
Ingxenye yesibili yalesi sihloko inikeza isibonelo sokuhlanza idatha, lapho kutholakala khona imiphumela yokusebenzisa imodeli ye-Schumann.
Ake ngethule imiphumela etholiwe:
Inani elilinganiselwe lamaphutha N = 3167 n.
Ipharamitha C, i-lambda nomsebenzi wokuthembeka:
Fig.17
Empeleni, i-lambda iyinkomba yangempela yokuqina okutholwa ngakho amaphutha esigabeni ngasinye. Uma ubheka ingxenye yesibili, isilinganiso sale nkomba kwaba amaphutha 42,4 ngehora, okuyinto ngempela kuqhathaniswa Schumann inkomba. Ngenhla, kunqunywe ukuthi izinga umthuthukisi athola ngalo amaphutha akufanele libe ngaphansi kwephutha elingu-1 kumarekhodi angu-250,4, lapho ehlola irekhodi elingu-1 ngomzuzu. Ngakho-ke inani elibalulekile le-lambda lemodeli ye-Schumann:
60/250,4 = 0,239617.
Okusho ukuthi, isidingo sokwenza izinqubo zokutholwa kwephutha kufanele senziwe kuze kube yilapho i-lambda, kusukela ku-38,964 ekhona, yehla yaba ngu-0,239617.
Noma kuze kube yilapho inkomba engu-N (inani lamaphutha okungenzeka) isusa n (inani elilungisiwe lamaphutha) yehla ngaphansi komkhawulo wethu owamukelwe - ama-pcs angu-1459.
