Yandex hosts biweekly training sessions on machine learning.
These meetings offer an opportunity for the participants of data analysis contests to meet, talk, and exchange experience. Each of these events is made up of a practical session and a report. The problems are taken from Kaggle and similar platforms.
The reports are given by successful participants of recent contests, who share their strategies and talk about the techniques used by their competitors.
