What this example teaches

Labels and Targets

Output

The experiment prepares features, labels, metrics and validation rows, trains or scores a small model pattern, and prints a metric you can compare.

Line-by-line explanation

  • Line 1 sets up the Labels and Targets example: dataset = [.
  • Line 2 adds one required part of the working pattern: {"feature": 1.2, "label": "low"},.
  • Line 3 adds one required part of the working pattern: {"feature": 3.8, "label": "high"},.
  • Line 4 adds one required part of the working pattern: {"feature": 2.4, "label": "medium"},.
  • Line 5 adds one required part of the working pattern: ].
  • Line 6 adds one required part of the working pattern: features = [row["feature"] for row in dataset].

Why this example is useful

This example is useful because it isolates labels and targets without surrounding noise, so you can see the idea clearly.

Where it is used in real projects

Labels and Targets appears in real Machine Learning work when a feature needs a clear pattern that can be reviewed and changed safely.

Beginner variation

Change one label, value or condition in the Labels and Targets example and run it again.

Advanced variation

Combine Labels and Targets with validation, error handling or reusable structure.
