    • Awarded to Igor Buzhinsky
      Silver medal in Kaggle competition: Jigsaw Multilingual Toxic Comment Classification Kaggle kesä 2020 Participated in a team of two persons. In this Kaggle competition, the task was to use TPUs to identify toxicity comments across multiple languages. Our solution was mainly based on ensembling across multiple models and data sources. Place 73/1621 in the leaderboard.
