Fundamentals of AI and ML

Learning Paradigms

Learning paradigms describe how a model receives training signals. The exam often tests whether labels, rewards, unlabeled data, or self-created objectives are used.

Concepts

  • Supervised learning trains from labeled examples with known outputs.
  • Unsupervised learning finds structure in unlabeled data.
  • Reinforcement learning learns actions from rewards and penalties in an environment.
  • Self-supervised learning creates training signals from the data itself and is common in foundation model pretraining.

Exam tips

  • Supervised learning uses labeled examples with known answers.
  • Unsupervised learning finds structure without labels.
  • Reinforcement learning learns from rewards and penalties.

Mode

Exam fidelity: AWS lists multiple choice and multiple response for this exam. Ordering, matching, and case-study items are supplemental learning exercises; their results stay in overall study accuracy but do not count toward exam-style accuracy. Difficulty labels describe this site's scenario complexity, not an AWS-published question rating.
