> Apply Similarity measures with clear evidence.

## Understand Similarity measures

For **Similarity measures**, begin with the problem it solves. Identify the inputs, constraints, and observable outcome before choosing an implementation.

## Practise deliberately

Create one small example for **Similarity measures** and verify its result before expanding it.

## A useful comparison

**Similarity measures** is like a route plan: it keeps each step connected to a destination.

Check your reasoning.

**Quiz:** What is the best first step for Similarity measures?

- [x] Define the goal and constraints.
- [ ] Copy an unverified example.
- [ ] Skip measurement.

*Answer:* Define the goal and constraints.. A clear goal and constraints make decisions reviewable.
