Understanding with Simple Calculations
Here’s how K-means clustering improves segmentation and accuracy:
| Step | Description | Example |
|---|---|---|
| Select Number of Clusters | Choose K (e.g., 3) groups to split the data into | K = 3 for behaviour segmentation |
| Initialise Centroids | Pick 3 initial random data points | Users A, B, C as cluster centres |
| Assign to Clusters | Calculate distanceDefinition Distance in SEO determines proximity, affecting l... between users and centroids | Grouped by behaviour similarity |
| Recalculate Centroids | Find new average for each group | Updated group behaviours A’, B’, C’ |
| Repeat Until Stable | Reassign until no change in grouping | Finalised clusters for targeting |
These steps generate focused clusters for content or user segmentation.
