Unsupervised learning has several sub-types. In this post, I will describe clustering.

1.Put Bunch of Data without Labeling into a Machine

When you are eating foods, you don't need to categorize your foods, such as this is carbohydrate, protein, and fat.  Your body digest food automatically.

Unsupervised learning is like above case. Just input tones of data and expect to organized data set with similarity.

2.Clustering.

One of the organizing way is called by clustering.

For instance, in social media, they recommend friends. they are already clustering you and they just recommend people who are in your cluster.

Clustering is one of the way of unsupervised learning, however, it's a popular method of unsupervised learning.

I hope we will discuss the other types of unsupervised learning soon.
