Common Pitfalls: Overfitting, Bias, and Hallucinations

Quick Summary

Overfitting, bias, and hallucination are different failure modes. Each has a different cause, detection method, and control, so they should not be treated as one vague problem called AI risk.

What you will learn
  • Differentiate overfitting, bias, and hallucination
  • Match each failure mode with an appropriate test
  • Design layered controls that include people and process
