Adaptive Learning Module Abstract

High-level Purpose and Responsibility

The adaptive learning module implements intelligent task selection and difficulty adaptation using multi-armed bandit algorithms and reinforcement learning principles. It dynamically adjusts learning experiences based on real-time performance feedback to optimize learning efficiency and maintain appropriate challenge levels for individual learners.

Key Data Structures and Relationships

  • AdaptiveLearner: Core adaptive learning system with bandit algorithm integration
