💻 Ozon Tech published recordings of 60 E-CODE 2026 talks
On September 12–13 in Moscow, Ozon Tech held its annual E-CODE conference, timed to Programmer's Day. Recordings of all 60 talks are already available on the ecode.ozon.tech website, and the first selection of the best presentations has been published in the official Ozon Tech channel.
🌍 Ozon showed how it is migrating its entire marketplace recommendation pipeline to neural network models — from candidate selection to final ranking — with multi-task optimization for sales, advertising, engagement, and LTV. The Large User Model architecture combines user signals, including negative feedback. A separate case study — measuring product dimensions on a conveyor at speeds up to 1 m/s using a stereo camera, Grounding DINO, SAM2, and 3D reconstruction.
👤 Recordings of 60 talks are available for free: you can learn how recommendation systems and industrial CV work at the scale of one of the largest marketplaces, without attending the conference. It is doubly useful for students: the E-CUP ML competition this season was exclusively for them, and the winners split a 7.2 million ruble prize fund for solving tasks on real Ozon data.
