Easy to mix up on the Microsoft AI-901 exam
Exam questions often use two ideas that sound alike. Learn the difference once and several questions become easy.
| Pair | The key difference | How to choose |
|---|---|---|
| Classification or Regression | Classification predicts a category or label, while regression predicts a continuous numeric value. | Use classification to decide whether a transaction is fraudulent; use regression to forecast next month's sales figure. |
| Image classification or Object detection | Image classification assigns a label to the whole image, while object detection finds and locates individual objects, usually with bounding boxes. | Choose classification to tag a photo as 'beach'; choose object detection to count and locate the cars in a car park photo. |
| Prompt engineering or Fine-tuning | Prompt engineering shapes the input given to a model at run time, while fine-tuning further trains the model so its weights change. | Start with better prompts for quick, cheap improvements; consider fine-tuning when you need consistent specialised behaviour that prompts cannot achieve. |
| Transparency or Accountability | Transparency is about people understanding how an AI system works and reaches outputs, while accountability is about people being responsible for the system's impact. | Document how a model decides to support transparency; assign owners and review processes to support accountability. |
