Advanced Multi-Document Summarization and User Engagement Enhancement

  • Engineered a SOTA multi-document summarization model for news aggregation, achieving an 87% human acceptance rate with less than 1% critical errors.
  • Designed automated news timelines for evolving events, resulting in a 2.8% increase in content depth and a 1.4% boost in user time spent.
  • Optimized ranking algorithms with a CTR prediction model, increasing daily active users by 4.3% and user engagement by 2.1%.
  • Created a novel similarity scoring formula, improving F1-score from 0.91 to 0.95 for news clustering.
Andrey worked on this case as the ML engineer at Yandex Zen.
