Microsoft Azure AI Fundamentals General 4

Question 1

Which Azure service allows developers to add pre-built AI capabilities to applications without needing machine learning expertise?

Accepted Answer

Azure AI Services (Cognitive Services)

Answer

Azure AI Services (formerly Cognitive Services) offers pre-built APIs for vision, language, speech, and decision tasks that developers can integrate without ML expertise.

Question 2

What is 'overfitting' in a machine learning model?

Accepted Answer

The model performs well on training data but poorly on new, unseen data

Answer

Overfitting occurs when a model memorizes training data so well that it fails to generalize to new data, resulting in low training error but high validation error.

Question 3

In Azure AI Vision, which feature identifies the age, gender, and emotion of people in photographs?

Accepted Answer

Face detection and analysis

Answer

Azure AI Vision's face detection and analysis feature can locate faces in images and return attributes such as estimated age, inferred gender, and detected emotion.

Question 4

Which Azure feature enables you to detect anomalies in time-series data such as server metrics or sensor readings?

Accepted Answer

Azure Anomaly Detector

Answer

Azure Anomaly Detector is an AI service that automatically identifies unexpected patterns in time-series data without requiring labeled training data.

Question 5

What does the term 'neural network' refer to in artificial intelligence?

Accepted Answer

A computational model inspired by the structure of the human brain

Answer

A neural network is a computational model made up of interconnected nodes (neurons) organized in layers, loosely inspired by the biological structure of the human brain.
