Personalization at Scale Using Recommendation Systems
Delivering hyper-personalized music discovery through behavioral ML models
The Challenge
Our Approach
We built a hybrid recommendation engine combining collaborative filtering with content-based and deep learning models. Core components included:
- Matrix factorization using implicit feedback (Spark ALS)
- NLP-powered song tagging using BERT for lyrics and genre embeddings
- Session-based RNN models to capture short-term listening patterns
- Online learning strategies for real-time personalization
The model output was A/B tested via a reinforcement learning loop to optimize for engagement metrics.
Stats
The Outcome
- 42% boost in daily active users
- 55% increase in personalized playlist consumption
- 2.1x better retention for new users within 14 days
- Real-time recommendations updated with <1 second latency
