Supervised or unsupervised
Use this for “An analyst runs k-means with 12 clusters, then names each cluster. Is that supervised or unsupervised classification?”
Sort
Is this step supervised or unsupervised?
Tap a card, then tap its group.
Ask whether known labels guide the computer, or the computer finds groups the analyst names later.
Assumptions
•
Supervised: the analyst labels training areas or points first, and the computer learns each class from them.
•
Unsupervised: the computer groups pixels by their values first (clustering), and the analyst names the groups afterward.
•
The test is when the labels arrive: before the computer sorts the pixels, or after.
