But here's an example:
I see a stove eye is black when cold, then when I see it turn red, I touch it. Ow, it hurts. That's supervised learning. Don't touch things that are glowing red when they don't normally glow red. Now, I see an iron pole glowing red. It's not a spiral like the stove eye, but it's not normally glowing red and now it is. I'd better not touch it. I can deduce that these two objects are made out of a similar material since they're normally black or gray and now glow red. I can also deduce that something glowing red means it's hot. That's unsupervised learning.
To me, unsupervised learning is looking at a fluffy object with four legs, eyes, a nose, tail, it moves, etc. and knowing that it's some kind of animal. Creating groups of things like k-means. Supervised learning is your mom telling you that this one example is a tiger. Unsupervised learning is understanding the delta between your one labeled example and the rest of the examples in your animal group is largest when the animal is NOT a tiger.
