A confidence score is the AI system’s estimate of how certain it is about its prediction or output, usually expressed as a percentage or probability.
Why it matters:
- Helps users judge whether to trust an AI’s response.
- Useful in areas like medical imaging (e.g., “90% confidence this is pneumonia”).
- Low confidence doesn’t always mean wrong — just that the system is uncertain.
Pro tip: Don’t treat confidence scores as absolute truth — they’re estimates, not guarantees. Use them as decision-support, not final answers.
