Momwe Kusungirako Kumagwiritsidwira Ntchito mu App mu Air

Kusunga wosuta mu pulogalamu yam'manja ndi sayansi yonse. Wolemba maphunzirowa adafotokoza zoyambira zake m'nkhani yathu ya VC.ru Kuwononga Kukula: kusanthula kwa pulogalamu yam'manja Maxim Godzi, Mtsogoleri wa Machine Learning pa App in the Air. Maxim amalankhula za zida zomwe zidapangidwa mukampani pogwiritsa ntchito chitsanzo cha ntchito pakusanthula ndi kukhathamiritsa kwa pulogalamu yam'manja. Njira yokhazikika yosinthira zinthu, yopangidwa mu App in the Air, imatchedwa Retentioneering. Mutha kugwiritsa ntchito zida izi pazogulitsa zanu: zina mwazo zili mkati mwayi waulere pa GitHub.

App in the Air ndi pulogalamu yomwe ili ndi ogwiritsa ntchito opitilira 3 miliyoni padziko lonse lapansi, yomwe mutha kuyang'anira maulendo apandege, kudziwa zambiri zakusintha kwanthawi yonyamuka/kutera, kulowa ndi mawonekedwe a eyapoti.

Kuchokera panjira kupita kunjira

Magulu onse achitukuko amapanga fayilo yolowera (njira yomwe cholinga chake ndi kuvomereza kwa ogwiritsa ntchito). Ichi ndi sitepe yoyamba yomwe imakuthandizani kuyang'ana dongosolo lonse kuchokera pamwamba ndikupeza mavuto ogwiritsira ntchito. Koma pamene mankhwala akukula, mudzamva zofooka za njirayi. Pogwiritsa ntchito fanjelo losavuta, simungawone kukula kosadziwika bwino kwa chinthu. Cholinga cha faniyo ndikuwunikanso magawo a ogwiritsa ntchito, kukuwonetsani ma metrics anthawi zonse. Koma faniyoyo imabisala mwanzeru zopatuka kuchokera ku zomwe zimachitika ku zovuta zodziwikiratu kapena, m'malo mwake, ntchito zapadera za ogwiritsa ntchito.

Ku App in the Air, tidapanga faniyo yathu, koma chifukwa cha zomwe zidapangidwa, tidakhala ndi galasi la ola. Kenako tinaganiza zokulitsa njirayo ndikugwiritsa ntchito chidziwitso cholemera chomwe pulogalamuyo imatipatsa.

Mukapanga fayilo, mumataya njira zolowera. Ma trajectories amakhala ndi machitidwe otsatizana ndi wogwiritsa ntchito komanso pulogalamuyo (mwachitsanzo, kutumiza zidziwitso zokankha).

Pogwiritsa ntchito ma timestamp, mutha kupanganso njira ya wogwiritsa ntchito mosavuta ndikupanga graph kwa aliyense wa iwo. Inde, pali ma graph ambiri. Chifukwa chake, muyenera kuphatikiza ogwiritsa ntchito ofanana. Mwachitsanzo, mutha kukonza onse ogwiritsa ntchito ndi mizere ya tebulo ndikulemba momwe amagwiritsira ntchito ntchito inayake.

Kutengera tebulo loterolo, tidapanga matrix ndikuyika ogwiritsa ntchito m'magulu pafupipafupi momwe amagwiritsidwira ntchito, ndiye kuti, ndi node pa graph. Izi nthawi zambiri zimakhala gawo loyamba lothandizira kuzindikira: mwachitsanzo, pakadali pano muwona kuti ogwiritsa ntchito ena sagwiritsa ntchito zina mwazonse. Titafufuza pafupipafupi, tinayamba kuphunzira kuti ndi mfundo ziti zomwe zili mu graph ndi "zazikulu", ndiye kuti, masamba omwe ogwiritsa ntchito amawachezera nthawi zambiri. Magawo omwe ali osiyana kwambiri malinga ndi milingo yomwe ili yofunika kwa inu amawunikidwa nthawi yomweyo. Pano, mwachitsanzo, pali magulu awiri a ogwiritsa ntchito omwe tidawagawa kutengera chisankho cholembetsa (panali magulu 16 onse).

Momwe mungagwiritsire ntchito

Poyang'ana ogwiritsa ntchito motere, mutha kuwona zomwe mumagwiritsa ntchito kuti muwasunge kapena, mwachitsanzo, kuwapangitsa kuti alembetse. Mwachilengedwe, matrix adzawonetsanso zinthu zoonekeratu. Mwachitsanzo, kuti omwe adagula zolembetsa adayendera skrini yolembetsa. Koma pambali pa izi, mutha kupezanso machitidwe omwe simukanadziwa mwanjira ina.

Chifukwa chake tidapeza mwangozi gulu la ogwiritsa ntchito omwe amawonjezera ndege, kuyitsata mwachangu tsiku lonse ndikuzimiririka kwa nthawi yayitali mpaka atawulukiranso kwinakwake. Tikadasanthula machitidwe awo pogwiritsa ntchito zida wamba, titha kuganiza kuti sanakhutire ndi momwe ntchitoyi ikuyendera: tingafotokozere bwanji kuti adagwiritsa ntchito tsiku limodzi koma sanabwerere. Koma mothandizidwa ndi ma graph tidawona kuti ali okangalika, kungoti ntchito yawo yonse imalowa tsiku limodzi.

Tsopano ntchito yathu yaikulu ndikulimbikitsa wogwiritsa ntchito woteroyo kuti agwirizane ndi pulogalamu ya kukhulupirika ya ndege yake pamene akugwiritsa ntchito ziwerengero zathu. Pamenepa, tidzalowetsa ndege zonse zomwe amagula ndikuyesera kumukankhira kuti alembetse akangogula tikiti yatsopano. Kuti tithetse vutoli, tinayambanso kugwirizana ndi Aviasales, Svyaznoy.Travel ndi ntchito zina. Wogwiritsa ntchitoyo akagula tikiti, pulogalamuyo imawalimbikitsa kuti awonjezere ndegeyo ku App in the Air, ndipo timaziwona nthawi yomweyo.

Chifukwa cha graph, tawona kuti 5% ya anthu omwe amapita kuwonetsero amaletsa. Tinayamba kupenda milandu yotereyi, ndipo tinawona kuti pali wosuta yemwe amapita ku tsamba loyamba, amayambitsa kugwirizana kwa akaunti yake ya Google, ndipo nthawi yomweyo amaletsa, amafikanso pa tsamba loyamba, ndi zina zotero. Poyamba tidaganiza kuti, "China chake sichili bwino ndi wogwiritsa ntchitoyu." Ndiyeno tinazindikira kuti, mwina, panali cholakwika mu ntchito. M'malo mwake, izi zitha kutanthauziridwa motere: wogwiritsa ntchito sanakonde zilolezo zomwe pulogalamuyo imapempha, ndipo adachoka.

Gulu lina linali ndi 5% ya ogwiritsa ntchito omwe amatayika pazenera pomwe pulogalamuyo imawalimbikitsa kuti asankhe imodzi kuchokera pamapulogalamu onse a kalendala pa smartphone yawo. Ogwiritsa amasankha makalendala osiyanasiyana mobwerezabwereza kenako ndikungotuluka mu pulogalamuyi. Zinapezeka kuti panali vuto la UX: munthu atasankha kalendala, amayenera kudina Done pakona yakumanja yakumanja. Kungoti si onse ogwiritsa ntchito adaziwona.

Chophimba choyamba cha App in the Air

Mu graph yathu, tawona kuti pafupifupi 30% ya ogwiritsa ntchito samapitilira chinsalu choyamba: izi ndichifukwa choti ndife aukali kukankhira wosuta kuti alembetse. Pazenera loyamba, pulogalamuyi imakupangitsani kuti mulembetse pogwiritsa ntchito Google kapena Triplt, ndipo palibe zambiri zodumpha kulembetsa. Mwa iwo omwe amachoka pazenera loyamba, 16% ya ogwiritsa ntchito dinani "Zambiri" ndikubwereranso. Tapeza kuti akufunafuna njira yolembetsera mkati mwa pulogalamuyo ndipo tidzayitulutsa muzosintha zina. Kuphatikiza apo, 2/3 mwa omwe amachoka nthawi yomweyo samadina kalikonse. Kuti tidziwe zomwe zikuwachitikira, tinapanga mapu a kutentha. Zikutheka kuti makasitomala akudina mndandanda wazinthu zamapulogalamu zomwe sizimadulikana.

Gwirani kamphindi kakang'ono

Nthawi zambiri mumatha kuwona anthu akupondaponda njira pafupi ndi msewu wa phula. Kusunga ndi kuyesa kupeza njira izi ndipo, ngati n'kotheka, kusintha misewu.

Zachidziwikire, ndizoyipa kuti timaphunzira kuchokera kwa ogwiritsa ntchito enieni, koma tidayamba kutsatira njira zomwe zikuwonetsa vuto la ogwiritsa ntchito. Tsopano woyang'anira malonda amalandira zidziwitso za imelo ngati kuchuluka kwa "lupu" kumachitika-pamene wogwiritsa ntchito abwereranso pazenera lomwelo mobwerezabwereza.

Tiyeni tiwone momwe ma trajectories a ogwiritsa ntchito nthawi zambiri amakhala osangalatsa kuyang'ana kuti asanthule zovuta ndi kukula kwa ntchito:

• Lupu ndi zozungulira. Malupu otchulidwa pamwambapa ndi pamene chochitika chimodzi chikubwereza njira ya wogwiritsa ntchito, mwachitsanzo, kalendala-kalendala-kalendala. Lupu yokhala ndi kubwerezabwereza zambiri ndi chizindikiro chodziwika bwino cha vuto la mawonekedwe kapena chizindikiro chosakwanira cha zochitika. Kuzungulira kulinso njira yotsekedwa, koma mosiyana ndi kuzungulira kumaphatikizapo zochitika zoposa chimodzi, mwachitsanzo: kuyang'ana mbiri ya ndege - kuwonjezera maulendo othawa - kuwonera mbiri ya ndege.
• Flowstoppers - pamene wogwiritsa ntchito, chifukwa cha zopinga zina, sangathe kupitiriza kuyenda komwe akufuna kupyolera muzogwiritsira ntchito, mwachitsanzo, chinsalu chokhala ndi mawonekedwe omwe sakuwonekera kwa kasitomala. Zochitika zoterezi zimachepetsa ndikusuntha njira ya ogwiritsa ntchito.
• Mfundo za Bifurcation ndizochitika zofunikira pambuyo pake njira zamakasitomala amitundu yosiyanasiyana zimasiyanitsidwa. Makamaka, awa ndi zowonera zomwe zilibe kusintha kwachindunji kapena kuyitanira kuchitapo kanthu ku zomwe mukufuna kuchita, zomwe zimakankhira ogwiritsa ntchito ena kuti azitsatira. Mwachitsanzo, zenera lina lomwe silikukhudzana mwachindunji ndi kugula zomwe zili mu pulogalamuyo, koma zomwe makasitomala amakonda kugula kapena kusagula zomwe zili, zitha kuchita mosiyana. Malo a Bifurcation amatha kukhala ndi chikoka pa zochita za ogwiritsa ntchito ndi chizindikiro chowonjezera - amatha kukhudza chisankho chogula kapena kudina, kapena chizindikiro chochotsera - amatha kudziwa kuti pakadutsa masitepe angapo wogwiritsa ntchitoyo asiya kugwiritsa ntchito.
• Malo osinthika omwe achotsedwa ndi omwe atha kukhala magawo awiri. Mutha kuwaona ngati zowonera zomwe zingapangitse kuti munthu achitepo kanthu, koma musatero. Izi zitha kukhalanso nthawi yomwe wogwiritsa ntchito ali ndi chosowa, koma sitimakwaniritsa chifukwa sitikudziwa. Kusanthula kwa trajectory kuyenera kulola kuti izi zidziwike.
• Malo osokoneza - zowonetsera / pop-ups zomwe sizimapereka phindu kwa wogwiritsa ntchito, sizimakhudza kutembenuka ndipo zimatha "kusokoneza" njira, kusokoneza wogwiritsa ntchito zomwe akufuna kuchita.
• Malo osawona ndi malo obisika a pulogalamuyo, zowonera ndi mawonekedwe omwe ndi ovuta kwambiri kuti wosuta afikire.
• Madontho - malo omwe magalimoto amadumphira

Nthawi zambiri, masamu amatilola kumvetsetsa kuti kasitomala amagwiritsa ntchito pulogalamuyo mosiyana kwambiri ndi momwe oyang'anira malonda amaganizira poyesa kukonza momwe angagwiritsire ntchito wogwiritsa ntchito. Atakhala muofesi ndikupita kumisonkhano yoziziritsa bwino kwambiri, zimakhala zovuta kulingalira mitundu yonse yazinthu zenizeni zomwe wogwiritsa ntchito amathetsa mavuto ake pogwiritsa ntchito pulogalamuyi.

Izi zimandikumbutsa nthabwala yayikulu. Woyesa amalowa mu bar ndikulamula: galasi la mowa, magalasi awiri a mowa, 2 magalasi a mowa, 0 magalasi a mowa, buluzi mu galasi, -999999999 galasi la mowa, qwertyuip magalasi a mowa. Wogula weniweni woyamba amalowa mu bar ndikufunsa komwe chimbudzi chili. Malowa akuyaka moto ndipo aliyense amafa.

Ofufuza zamalonda, omizidwa kwambiri ndi vutoli, adayamba kuyambitsa lingaliro la micromoment. Wogwiritsa ntchito masiku ano amafunikira yankho lachangu pamavuto awo. Google idayamba kuyankhula za izi zaka zingapo zapitazo: kampaniyo idatcha ogwiritsa ntchito ngati micro-mphindi. Wogwiritsa ntchito amasokonekera, amatseka pulogalamuyo mwangozi, samamvetsetsa zomwe zimafunikira kwa iye, amalowetsanso patatha tsiku limodzi, amaiwalanso, kenako amatsatira ulalo womwe mnzake adamutumizira mthengayo. Ndipo magawo onsewa satha kupitilira masekondi 20.

Kotero ife tinayamba kuyesa kukhazikitsa ntchito yothandizira kuti ogwira ntchito amvetse zomwe vuto linali pafupifupi nthawi yeniyeni. Panthawi yomwe munthu amabwera ku tsamba lothandizira ndikuyamba kulemba funso lake, tikhoza kudziwa chomwe chili vuto, podziwa njira yake - zochitika 100 zotsiriza. M'mbuyomu, tidasinthiratu kugawa kwa zopempha zonse m'magulu pogwiritsa ntchito kusanthula kwa ML kwa zolemba zopempha zothandizira. Ngakhale kupambana kwamagulu, pamene 87% ya zopempha zonse zagawidwa molondola m'magulu 13, ndi ntchito ndi trajectories yomwe ingapeze yankho loyenera kwambiri pazochitika za wogwiritsa ntchito.

Sitingathe kumasula zosintha mwachangu, koma timatha kuzindikira vutoli ndipo, ngati wogwiritsa ntchito atsatira zomwe taziwona kale, mutumize zidziwitso zokankhira.

Tikuwona kuti ntchito yokonza pulogalamuyo imafuna zida zambiri zophunzirira njira za ogwiritsa ntchito. Kupitilira apo, podziwa njira zonse zomwe ogwiritsa ntchito amatenga, mutha kukonza njira zofunika, ndipo mothandizidwa ndi zomwe zili makonda, zidziwitso zokankhira ndi zinthu zosinthira za UI "ndi dzanja" zimatsogolera wogwiritsa ntchito zomwe akuyenera kuchita zomwe zimagwirizana ndi zosowa zake ndikubweretsa ndalama. , data ndi mtengo wina wabizinesi yanu.

Zomwe muyenera kuzizindikira

• Kuwerenga kutembenuka kwa ogwiritsa ntchito pogwiritsa ntchito ma fayilo mwachitsanzo kumatanthauza kutaya zambiri zomwe pulogalamuyo imatipatsa.

• Kusanthula kosungika kwazomwe zimachitika pazithunzi kumakuthandizani kuwona zomwe mumagwiritsa ntchito kusunga ogwiritsa ntchito kapena, mwachitsanzo, kuwalimbikitsa kuti alembetse.
• Zida zosungira zimathandizira zokha, munthawi yeniyeni, kutsatira zomwe zikuwonetsa zovuta za ogwiritsa ntchito, kupeza ndi kutseka nsikidzi pomwe zinali zovuta kuziwona.

• Amathandiza kupeza machitidwe osadziwika bwino a khalidwe la ogwiritsa ntchito.

• Zida zosungirako zimathandizira kupanga zida za ML zodziwikiratu zolosera zochitika zazikulu za ogwiritsa ntchito ndi ma metric: kutayika kwa ogwiritsa ntchito, LTV ndi ma metric ena ambiri omwe amatsimikiziridwa mosavuta pa graph.

Tikumanga gulu mozungulira Retentioneering kuti tisinthane malingaliro aulere. Mutha kuganiza za zida zomwe tikupanga monga chilankhulo chomwe akatswiri ndi zinthu zochokera kumitundu yosiyanasiyana yamafoni ndi intaneti amatha kusinthana malingaliro, njira zabwino kwambiri ndi njira. Mutha kuphunzira momwe mungagwiritsire ntchito zida izi mumaphunzirowa Kuwononga Kukula: kusanthula kwa pulogalamu yam'manja Chigawo cha Binary.
