Hallucinations and Reliability

Lesson goals

• Probabilistic generation
• Missing grounded sources
• Verification, retrieval, and review

Core idea

Why models can produce convincing but false information.

1. Probabilistic generation: understand it in context, identify inputs and outputs, and define how the result will be verified.

2. Missing grounded sources: understand it in context, identify inputs and outputs, and define how the result will be verified.

3. Verification, retrieval, and review: understand it in context, identify inputs and outputs, and define how the result will be verified.

Practical example

Consider a real application of “Hallucinations and Reliability.” Start small, identify available data, and compare the system with a clear baseline before expanding it.

Check your understanding

1. Explain “Hallucinations and Reliability” in your own words.
2. Give one appropriate and one misleading application.
3. What risk or limitation should be monitored?
