Supervised Learning: Train once, deploy static model; Contextual Bandits: Deploy once, allow the agent to adapt actions based on content and its corresponding reward. The author created a visual.Supervised learning is a staple in machine learning for well-defined problems, but it struggles to adapt to dynamic environments: enter contextual bandits.
This blog explores the differences between supervised learning and contextual bandits. From personalization engines to real-time pricing, contextual bandits provide an edge by continuously learning from feedback.
We will work hands-on with algorithms like Thompson Sampling and LinUCB to learn when and why contextual bandits outperform traditional static models trained with supervision.
Knowing the appropriate model for a given problem is essential in our data-driven world. Supervised learning has dominated the landscape for years, providing reliable solutions for static problems.
Lately, contextual bandits have emerged as a powerful alternative as applications grow more complex and require systems that adapt in real-time. They offer a sophisticated approach to learning and decision-making, whether recommending products, setting dynamic prices, or optimizing ad placements.
If youβre navigating the challenges of user personalization, dynamic environments, or exploration-exploitation trade-offs, this blog is for you!
