Tailoring content, offers, or experiences to individuals using their preferences, behavior, and context.
DESCRIPTION
Personalization leverages data and models to deliver relevant experiences for each user. Techniques include collaborative filtering, content-based methods, contextual bandits, and reinforcement learning. Success depends on high-quality features, experimentation, and ethical use of personal data. Personalization impacts engagement, conversion, and retention. Governance and privacy controls are crucial to avoid bias, over-targeting, or regulatory issues.
