AI-900Domain 2: Describe Fundamental Principles of Machine Learning on AzureMachine Learning PrincipleseasySingle choice

In a dataset used to predict delivery time, which columns would be the label and which would be features?

A.Label = delivery time; features = distance, weather, traffic, package weight

Correct — inputs are features, the target is the label.

B.Label = distance; features = delivery time

Distance is an input — can't be the label for predicting delivery time.

C.Labels and features are interchangeable

They have distinct roles — swapping them inverts the problem.

D.Features = the predicted output; label = the inputs

Reversed definition.

Why this answer

Features (x) are the input variables the model learns from; the label (y) is the value being predicted. 'Past deliveries with known outcomes' provides labeled training data; the model learns f(features) → label.
