Algorithm kumbuyo kwa nyimbo

Pitani, American Idol.

Nkhani yotsatira yachipambano mumakampani anyimbo sidzapezeka m'mipikisano yamaluso apamwamba. M'malo mwake, izindikirika m'maseti a data ndi ma algorithms ovuta opangidwa kuti awulule kagwiritsidwe ntchito ndi momwe bizinesi ikuyendera.

Pamwamba, njirayi imamveka ngati yowuma komanso yopanda kukhudzidwa kuposa zomwe Simon Cowell amatsutsa, koma ndiyo njira yabwino kwambiri yomwe anthu amasankhira "chinthu chachikulu chotsatira." Nthawi zonse anthu akadina maulalo a YouTube, amaika zithunzi za konsati pa Twitter, kapena kucheza zamagulu pa Facebook, amathandizira pazambiri zomwe zimatchedwa data yayikulu. Mawuwa amatanthauza kusonkhanitsa deta zomwe zimakhala zazikulu komanso zimakhala ndi maubwenzi ovuta. Ganizirani za kapangidwe ka malo ochezera a pa Intaneti. Zili ndi mamiliyoni a mbiri ya ogwiritsa ntchito omwe amalumikizidwa palimodzi ndi maubwenzi, 'zokonda', umembala wamagulu, ndi zina zotero.Zowona, deta yayikulu imawonetsa mawonekedwe a nsanjazi.

M'makampani oimba, deta yayikulu imapangidwa ndi zochitika monga kugulitsa pa intaneti, kutsitsa, ndi kulumikizana komwe kumachitika kudzera m'mapulogalamu kapena malo ochezera. Miyezo yoyezedwa imaphatikizapo "kuchuluka kwa nyimbo zomwe nyimbo zimaseweredwa kapena kudumpha, komanso kuchuluka kwa momwe amakokera pama media ochezera potengera zomwe Facebook amakonda ndi ma tweets." Zida zowunikira zimatsimikizira kutchuka kwamasamba onse ndikulembetsa ndemanga zabwino kapena zoyipa za ojambula. Zonse pamodzi, chidziwitsochi chimazindikiritsa zomwe zikuchitika, kuwunika kuchuluka kwa akatswiri ojambula, ndikupangitsa kuti agulitse kudzera paokha, malonda, matikiti akonsati, ngakhale kulembetsa kumasewera otsatsira nyimbo.

Pankhani yopeza talente yatsopano, deta yayikulu imakhala ndi gawo lofunikira pakupangitsa chidwi pamalebulo akuluakulu. Nthawi zambiri, makampani amawerengera tsamba la ojambula, 'like', ndi otsatira. Kenako, manambala atha kufananizidwa mosavuta ndi ojambula ena amtundu womwewo. Kachitidwe kamodzi katulutsa anthu zikwi zana limodzi ndi otsatira a Facebook kapena Twitter, oyang'anira talente amazindikira ndikuyamba kukopa chidwi pamakampani opanga nyimbo.

Zambiri pakusankha kugunda kwakukulu kotsatira kwa Top 40

Kutha kuzindikira zomwe zikuchitika komanso kulosera megastar yotsatira imabwera ndi mphotho zazikulu zachuma kwa aliyense amene akukhudzidwa. Mwachitsanzo, asayansi a data adaphunzira momwe ma media amtundu wa iTunes amakhudzidwira ndikutsata malonda poyerekeza ma metric amunthu ndi ndalama za mnzake. Iwo adatsimikiza kuti zochitika zapa social media zimagwirizana ndi kuchuluka kwa ma album ndi malonda. Mwachindunji, mawonedwe a YouTube amakhudza kwambiri malonda; kupeza komwe kudapangitsa kuti olemba ambiri akhazikitse makanema anyimbo akulu akulu papulatifomu kuti alimbikitse osakwatiwa. Asanawononge mamiliyoni ambiri popanga makanema, kusanthula kumagwiritsidwa ntchito kuti azindikire nyimbo zomwe zitha kutchuka potengera zomwe anthu akutsata pa intaneti. Kulondola kwa maulosi amenewa kumagwirizana ndi kusanthula kwakukulu kwa deta.

Amalonda omwe ali m'makampani opanga nyimbo tsopano akuyesera njira zatsopano zopangira njira zomwe zimakolola zambiri mwaluso komanso molondola. Chimodzi mwa zitsanzo zodziwika bwino ndi mgwirizano pakati pa EMI Music ndi Data Science London yotchedwa The EMI Million Interview Dataset. Imafotokozedwa kuti ndi "chimodzi mwazolemba zolemera kwambiri komanso zazikulu kwambiri zoyamikirira nyimbo zomwe zidapezekapo - gulu lalikulu, lapadera, lolemera, lapamwamba kwambiri lopangidwa kuchokera ku kafukufuku wapadziko lonse lapansi lomwe lili ndi zokonda, malingaliro, machitidwe, kuzolowera, ndi kuyamikira nyimbo monga momwe zafotokozedwera okonda nyimbo."

David Boyle, Wachiwiri kwa Wachiwiri kwa Purezidenti wa Insight ku EMI Music, akufotokoza kuti, "(Izi) zili ndi zoyankhulana miliyoni miliyoni zomwe zikukambitsirana mitu monga kukhudzika kwa mtundu wina wanyimbo ndi mtundu wang'ono, njira zomwe amakonda zopezera nyimbo, oimba omwe amakonda nyimbo, malingaliro okhudza kubera nyimbo, kusanja kwa nyimbo, mitundu ya nyimbo, komanso kuchuluka kwa anthu okonda nyimbo. ”

Cholinga cha pulojekitiyi ndikutulutsa chidziwitso ichi kwa anthu ndikukweza bwino bizinesi mkati mwa makampani oimba.

"Tachita bwino kwambiri kugwiritsa ntchito deta kutithandiza ife ndi akatswiri athu kumvetsetsa ogula, ndipo ndife okondwa kugawana zambiri zathu kuti tithandizire ena kuchita zomwezo," akutero Boyle.

Mu 2012, EMI Music and Data Science London idatenga pulojekitiyi sitepe imodzi mwakuchita Music Data Science Hackathon. EMC, mtsogoleri wapadziko lonse mu sayansi ya data ndi mayankho akuluakulu a data, adalowa nawo bizinesiyo ndikupereka zomangamanga za IT. Kwa nthawi ya maola 24, asayansi okwana 175 adapanga njira 1,300 ndi ma algorithms kuti ayankhe funso: "Kodi mungadziwiretu ngati omvera angakonde nyimbo yatsopano?" Zotsatira zinawonetsa mphamvu ya luntha lamagulu ndipo otenga nawo mbali adapanga mafomu omwe amafotokozedwa kuti ndi apamwamba padziko lonse lapansi.

"Zidziwitso zomwe zavumbulutsidwa mu hackathon iyi zikuwonetsa mphamvu ndi kuthekera komwe Big Data ili nayo - potulukira mwaluntha komanso chifukwa cha kuchuluka kwabizinesi kwa mabungwe amtundu uliwonse," akutero Chris Roche, Mtsogoleri Wachigawo wa EMC Greenplum.

Koma mumalipira bwanji ojambula?

Makampani atatsimikiza kuti nyimboyo yagunda bwino ndikuyitulutsa ngati imodzi, imawerengera bwanji ndalama zomwe nyimboyo imasewera pamasamba ochezera kapena malo ochezera? Pakalipano, "malebulo amitundu yonse akukumana ndi vuto lomwe likukulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulirakulira?

Chimodzi mwazovuta zapakati pamalingaliro a kasamalidwe ka chidziwitso ndikuti machitidwe ambiri owongolera ma database sanapangidwe kuti azitha kuyang'anira ma data omwe ndi akulu komanso ovuta ngati data yayikulu. Mwachitsanzo, kukula kwa mafayilo a digito opangidwa ndi omwe amagawa nyimbo kumaposa zomwe mapulogalamu monga Excel angachite. Izi zimabweretsa mavuto kuphatikiza kusowa kwa data ndi zilembo zamafayilo zomwe sizigwirizana ndi pulogalamu yowerengera ndalama.

Nthawi zambiri, nkhani zonsezi zimasanjidwa ndi akauntanti, ndikuwonjezera nthawi ndi ntchito ku ntchito yolemetsa kale. Nthawi zambiri, gawo lalikulu lazolembazo limalumikizidwa ndi dipatimenti yowerengera ndalama.

Pofuna kuthana ndi izi, amalonda amapanga nsanja zanzeru zamabizinesi zomwe zimatha kukonza ndikusanthula deta yayikulu. Chimodzi mwa zitsanzo zabwino kwambiri ndi kampani ya ku Austria Rebeat, yomwe imalongosola ntchito zawo ngati "kuwerengera ndalama zachifumu ndikudina katatu." Yakhazikitsidwa mchaka cha 2006, idakula mwachangu kukhala wotsogola wotsogola ku Europe ndipo imapereka mwayi wopeza ntchito za digito 300 padziko lonse lapansi. Kwenikweni, Rebeat imathandizira machitidwe owerengera ndalama ndikuwongolera ntchito zakumbuyo, monga kufananiza magawo a data mu pulogalamu yowerengera ndalama, kotero dipatimenti yowerengera ndalama ndi yaulere kuyang'anira bajeti. Amaperekanso maziko oyendetsera ndalama zachifumu molingana ndi mapangano amgwirizano, mapangano achindunji ndi malo ogulitsa nyimbo zama digito, kupanga ma graph kuti azitsatira malonda, ndipo koposa zonse, kutumiza deta ku mafayilo a CSV.

Inde, utumiki umabwera ndi mtengo. Forbes inanena kuti zolemba zojambulira ziyenera kugwiritsa ntchito Rebeat ngati wogawa kuti athe kupeza zidziwitso zamakampani, zomwe zimawononga 15% yogulitsa katundu ndi chindapusa chokhazikika cha $ 649 chaka chilichonse. Komabe, kuyerekeza kumasonyeza kuti nthawi zambiri zowerengera ndalama za lebulo nthawi zambiri zimawononga ndalama zambiri, zomwe zikutanthauza kuti kusaina ndi Rebeat kumatha kukhala kopulumutsa ndalama.
