What this example teaches
Decision Trees
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 Decision Trees 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 decision trees without surrounding noise, so you can see the idea clearly.
Where it is used in real projects
Decision Trees 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 Decision Trees example and run it again.
Advanced variation
Combine Decision Trees with validation, error handling or reusable structure.
