I kēia mau lā, ua hoʻokō ʻia ka pale hoʻoilo aʻe o nā haumāna puka ʻekolu o kā mākou papahana ʻenehana - Technopark (Bauman MSTU), Technosphere (Lomonosov Moscow State University) a me Technotrek (MIPT). Ua hōʻike nā hui i nā hoʻokō ʻelua o kā lākou mau manaʻo a me nā hoʻonā i nā pilikia ʻoihana maoli i manaʻo ʻia e nā māhele like ʻole o Mai.ru Group.
Ma waena o nā papahana:

- He lawelawe e hōʻuluʻulu ana i nā hoʻolaha, nā uku a me nā hāʻawi mai ka papa inoa leka.
- Huli maka no nā lole.
- ʻO ka lawelawe no ka hele ʻana i ka puke uila me ka koho hoʻolimalima.
- ʻO ka mīkini ʻai meaʻai akamai.
- alakaʻi leo o kēia wā.
- Papahana "Mail.ru Tasks"
- Ke kelepona paʻalima o ka wā e hiki mai ana.
Makemake mākou e haʻi aku iā ʻoe i nā mea kikoʻī e pili ana i ʻeono mau papahana i hōʻike nui ʻia e nā lālā jure a me nā kumu aʻoaʻo.
Huli maka no nā lole
Ua hōʻike ʻia ka papahana e kahi hui o nā haumāna puka ʻo Technosphere. Wahi a nā mea noiʻi, ʻo ka mākeke fashion ma Rūsia ma 2018 ua kokoke i 2,4 trillion rubles. Ua hana nā kāne i kahi lawelawe i hoʻonohonoho ʻia ma ke ʻano he kōkua akamai no ke kūʻai ʻana i nā ʻano waiwai like ʻole. He hoʻonā B2B kēia e hoʻonui i ka hana o nā hale kūʻai pūnaewele.
I ka wā o ka ho'āʻo ʻana o UX, ua ʻike nā mea kākau o ka papahana ma o ka "ʻaʻahu like" maopopo ka poʻe i ka like ʻole i ke kala a i ʻole ke ʻano, akā i nā ʻano o ka lole. No laila, ua hoʻomohala nā kāne i kahi ʻōnaehana ʻaʻole e hoʻohālikelike wale i nā kiʻi ʻelua, akā hoʻomaopopo i ka pili semantic. Hoʻouka ʻoe i kahi kiʻi o ka lole āu e makemake ai, a koho ka lawelawe i nā huahana e pili ana i kona mau ʻano.
ʻO ka ʻenehana ke hana nei ka ʻōnaehana penei:
Ua aʻo ʻia ka Cascade Mask-RCNN neural network no ka ʻike a me ka hoʻokaʻawale ʻana. No ka hoʻoholo ʻana i nā hiʻohiʻona a me ka like o nā lole, hoʻohana ʻia kahi neural network e pili ana i ResNext-50 me nā poʻo he nui no nā hui o nā ʻano, a me Triplet loss no nā kiʻi o hoʻokahi huahana. Ua hoʻokō ʻia ka papahana holoʻokoʻa ma muli o ka microservice architecture.
I ka wā e hiki mai ana ua hoʻolālā ʻia:
- E hoʻomaka i kahi lawelawe no nā ʻano lole a pau.
- E hoʻomohala i API no nā hale kūʻai pūnaewele.
- E hoʻomaikaʻi i ka hoʻopunipuni ʻano.
- E aʻo e hoʻomaopopo i nā nīnau ma ka ʻōlelo kūlohelohe.

Ke kelepona paʻalima o ka wā e hiki mai ana
Papahana o ka hui Technopark. Ua hana nā haumāna i kahi noi me kahi papa TV no nā kaila hoʻolaha kikohoʻe Lūkini nui, kahi i hoʻohui ʻia i ka hana o ka nānā ʻana i nā kaha me ka hoʻohana ʻana i IPTV (nā kahawai pūnaewele) a i ʻole kahi antenna.
ʻO ka mea paʻakikī loa ka hoʻopili ʻana i ka antenna i ka polokalamu Android: no kēia mea ua hoʻohana lākou i kahi tuner, kahi i kākau ai nā mea kākau i kahi mea hoʻokele. ʻO ka hopena, ua loaʻa iā mākou ka manawa e nānā i ka TV a hoʻohana i ke alakaʻi papahana TV ma Android i hoʻokahi noi.

He lawelawe e hōʻuluʻulu i nā hoʻolaha, nā uku a me nā hāʻawi mai nā papa leka uila
He papahana kēia ma ke kikowaena o nā ʻenehana hoʻolaha a me nā leka uila. Ua piha kā mākou pahu leta i nā spam a me nā leka uila. I kēlā me kēia lā, loaʻa iā mākou nā leka me nā uku pilikino, akā wehe mākou iā lākou me ka liʻiliʻi, me ka ʻike ʻana iā lākou he "hoʻolaha pono ʻole." Ma muli o kēia, lilo nā mea hoʻohana i nā pōmaikaʻi a loaʻa nā mea hoʻolaha i nā poho. Ua hōʻike ʻia kahi haʻawina e Mail.ru Mail e makemake ana nā mea hoʻohana e ʻike i kahi hōʻuluʻulu o nā uku i loaʻa iā lākou.
ʻO ka papahana hōʻiliʻili i ka ʻike e pili ana i nā hoʻemi a me nā hoʻolaha mai kāu nūhou a hōʻike iā lākou ma ke ʻano o kahi lipine o nā kāleka e hiki ai iā ʻoe ke hele i ka pūnaewele hoʻolaha a i ʻole leka uila. Hiki i ka polokalamu ke hana me kekahi mau pahu leta i ka manawa hookahi. Aia kahi papa inoa o nā waihona i koho ʻia.
He hale hana microservice ka papahana a he ʻekolu mau ʻāpana nui:
- ʻAe ʻia ʻo OAuth no ka hoʻopili maʻalahi o nā pahu leta.
- ʻOhi a nānā ʻana i nā leka me nā hoʻolaha.
- Ka mālama ʻana a me ka hōʻike ʻana i nā kāleka hōʻemi.
Hoʻohana ka papahana i ka ʻenehana hana ʻōlelo kūlohelohe me ka hoʻohana ʻana i nā kumuwaiwai GPU: hiki i nā kiʻi accelerators ke hoʻonui i ka wikiwiki o ka hana ʻana ma 50 mau manawa. Hoʻokumu ʻia ka algorithm ma kahi ʻōnaehana nīnau-pane, kahi e hiki ai iā ʻoe ke hoʻohui koke i nā ʻāpana waiwai e like me nā koi ʻoihana hou.

He hoʻolālā nui nā haumāna no ka hoʻomohala hou ʻana i ka papahana, ʻo ia nā mea aʻe:
- Hoʻohui me nā lawelawe leka uila.

Papahana "Mail.ru Tasks"
Ua ʻike ʻia ka papahana e nā jure a me nā kumu aʻoaʻo.
ʻO "Tasks Mail.ru" ka lawelawe kūʻokoʻa mua no ka mālama ʻana i kahi papa inoa hana, i hoʻomohala ʻia e ka hui. I nā mahina e hiki mai ana, e hoʻololi ʻo Tasks i nā papa inoa hana ma Mail.ru Calendar, a ma hope o ka hiki ʻana o ka papahana no nā mea hoʻohana a pau, e hoʻohui ʻia i loko o Mail.ru mobile a me ka pūnaewele Mail.
Ua hoʻokō ʻia ka papahana me ka hoʻohana ʻana i nā ala Offline-first a me Mobile-first. ʻO ia hoʻi, hiki iā ʻoe ke hoʻohana i ka palapala noi pūnaewele i kēlā me kēia manawa, ma nā wahi a me nā mea āpau. ʻAʻole pili ka ʻike pūnaewele: mālama ʻia ka ʻikepili a hoʻonohonoho ʻia.

ʻEkolu mau ʻāpana nui o ka noi: "Profile", "Camera" a me "History".
Ma ka "Profile" hoʻonoho ʻoe i kāu mau makemake: ma ka ʻāpana "Ingredients" hiki iā ʻoe ke haʻalele i kāu ʻai i kekahi o nā mea 60 i hoʻokomo ʻia i loko o ka waihona a heluhelu i ka ʻike e pili ana i nā E-supplements.

ʻElua mau ʻano ma ka ʻāpana "Camera": ka nānā ʻana i nā barcode a me ka ʻike ʻana i nā mea kanu a me nā huaʻai. Ma hope o ka nānā ʻana i ka barcode, e loaʻa iā ʻoe ka ʻike āpau e pili ana i ka huahana. ʻO nā mea i hoʻokaʻawale ʻia e hōʻike ʻia i ka ʻulaʻula.

ʻO ka lawelawe no ke kūʻai ʻana i nā makana me ka ʻoiaʻiʻo hoʻonui
Ua loaʻa i kēlā me kēia kanaka nā makana hōʻailona ma kahi o hoʻokahi manawa i ko lākou ola. ʻO ka manawa pinepine, no nā kānaka, ʻoi aku ka mea nui o ka nānā ʻana ma mua o ka makana i loaʻa iā lākou. ʻAʻole maikaʻi kēlā mau makana, akā ʻo kā lākou hana ʻana a me ka hoʻokuʻu ʻana he hopena maikaʻi ʻole i ke ʻano o kā mākou honua. ʻO kēia ke ʻano o ka manaʻo o nā mea kākau o ka papahana e hana i kahi lawelawe no ke kūʻai aku ʻana i nā makana me ka ʻoiaʻiʻo hoʻonui.
No ka ho'āʻoʻana i ka pili o ka manaʻo, ua hana mākou i kahi haʻawina. ʻO 82% o nā mea pane i kū i ka pilikia o ke koho ʻana i kahi makana. No 57% o ka poʻe pane, ʻo ka paʻakikī nui i ke koho ʻana ʻo ka hopohopo ʻaʻole e hoʻohana ʻia kā lākou mau makana. Ua mākaukau ʻo 78% o nā kānaka e hoʻololi e hoʻoponopono i nā pilikia kaiapuni.
Ua hoʻopuka nā mea kākau i ʻekolu mau manaʻo:
- Noho nā makana i ka honua honua.
- ʻAʻole lākou e lawe i ka lewa.
- Loaʻa kokoke.
No ka hoʻokō ʻana i ka ʻoiaʻiʻo i hoʻonui ʻia ma ka pūnaewele, ua koho nā mea kākau i ka waihona AR.js, aia ʻelua mau ʻāpana nui:
- ʻO ka mea mua ke kuleana no ke kaha kiʻi ʻana ma luna o ke kahawai kamera me ka hoʻohana ʻana iā A-Frame a i ʻole Three.js.
- ʻO ka ʻāpana ʻelua ʻo ARToolKit, nona ke kuleana no ka ʻike ʻana i kahi māka (kahi ʻano kūikawā i hiki ke paʻi ʻia a hōʻike ʻia paha ma ka pale o kekahi mea ʻē aʻe) i ke kahawai puka pahu pahu. Hoʻohana ʻia ka māka e hoʻonoho i nā kiʻi. ʻAʻole ʻae ka hele ʻana o ARToolKit iā ʻoe e hana i ka ʻoiaʻiʻo hoʻonui ʻole me ka hoʻohana ʻana iā AR.js.
Hūnā ʻo AR.js i nā lua he nui. No ka laʻana, hiki i kona hoʻohana pū ʻana me A-Frame ke "haʻihaʻi" i nā ʻano a puni ka pūnaewele. No laila, ua hoʻohana nā mea kākau i kahi "puʻupuʻu" o AR.js + Three.js, i kōkua i ka hoʻoponopono ʻana i kekahi o nā pilikia. A e hoʻokomo iā AR.js e pili ana i Three.js i React, kahi i kākau ʻia ai ka pūnaewele papahana, pono mākou e hana i kahi waihona AR-Test-2 (), ka mea e hoʻokō i kahi ʻāpana React kaʻawale no ka hoʻohana ʻana iā AR.js ma muli o Three.js. Ua hoʻokō ʻia ka nānā ʻana i ke kumu hoʻohālike i ka ʻoiaʻiʻo i hoʻonui ʻia a me 3D (no nā polokalamu me ka ʻole o ke kāmele).
Eia nō naʻe, ua ʻike ʻia ma hope ʻaʻole maopopo i nā mea hoʻohana i ke ʻano o ka marker a pehea e hoʻohana ai. No laila, ua hoʻololi nā mea kākau i ka ʻenehana , i kēia manawa e hoʻomohala ʻia nei e Google. Hoʻohana ʻo ia iā ARKit (iOS) a i ʻole ARCore (Android) e hana i nā hiʻohiʻona ma AR me ka ʻole o kahi māka. Hoʻokumu ʻia ka ʻenehana ma Three.js a loaʻa kahi mea nānā hiʻohiʻona 3D. Ua ʻoi aku ka maikaʻi o ka hoʻohana ʻana o ka papahana, akā naʻe, e ʻike i ka mea i hoʻonui ʻia, pono ʻoe i kahi mea me iOS 12 a i ʻole.
