ML problems in crowdsoursing platform Yandex.Toloka.
Vladimir Kukushkin, Yandex
Crowdsourcing platform is a two-sided market where customers and workers look up each other. Customers place their tasks (usually related to machine learning purposes, such as collecting ground-truth labels for their datasets), workers do these tasks gaining money. As a platform, we should regulate their relationships effectively, increasing satisfaction of the both sides. Generally, there are many examples of two-sided markets: Uber, booking.com, AirBnB, etc. But crowdsourcing market has its own specific features: online job, low payments, low entry barrier for users and high entry barrier for customers and many others. The speech is devoted to machine learning problems we face with every day.
