Intermediate

Using reinforcement learning for recommendation systems is a fairly novel field of academic studies. Sergey Ermolin and Vineet Khare provide a step-by-step overview on how to implement, train, and deploy a reinforcement learning (RL)-based recommender system with real-time multivariate optimization. They show you how leverage RL to implement a recommender system that optimizes an advertisement message that promotes adoption of merchant’s services.

Outline:

  • Introduction to reinforcement learning and recommender system concepts
  • AWS account setup and SageMaker RL environment configuration
  • Recommender system use case (based on this KDD-2017 paper): problem statement, algorithm outline, implementation outline, simulation environment outline, and results and references
  • Detailed walk-through of the prepared Python Jupyter notebook with algorithm implementation
  • Step-by-step Jupyter notebook execution
  • Results of simulation experiments
  • Analysis of the results and suggestions for further experiments
  • Discussion, conclusions, closing remarks, and Q&A

Prerequisite knowledge

  • Familiarity with Python and Jupyter notebooks
  • A basic understanding of reinforcement learning concepts (useful but not required)

What you'll learn

  • Learn to apply reinforcement learning to RecSys use cases and use an end-to-end reinforcement learning platform to rapidly prototype and implement a typical use case
