🛎️ What Is a Mapping?
- A mapping shows how one value links to another value. We say X is mapped to Y using an arrow.
- For example, time is mapped to speed, so each time value has a corresponding speed.
🛎️ How to Visualise Mapping?
- You can use a table and a graph to visualise the mapping.
- A table shows exactly which X value matches each Y value.
- A graph shows visually how Y changes when X changes.
🛎️ Using Mappings in Real Life
- Categories, such as types of balls, can be mapped to weights.
- Each input and its corresponding output can be shown in a table or graph.
- When the input is discrete categories, you should not join the points with a line.
