Netflix uses both Supervised and Unsupervised Learning (along with some Reinforcement Learning) for different aspects of its platform.

Netflix uses both:
✅ Supervised Learning → Personalized recommendations based on user history.
✅ Unsupervised Learning → Clustering users & content into groups for better suggestions.
✅ Reinforcement Learning → Optimizing UI & thumbnails based on user interactions.

Netflix’s AI system is a hybrid, making recommendations smarter over time.
