Machine Learning with Python - Clustering

• What is clustering?

 

A group of objects that are similar to other objects in the cluster, and dissimilar to data points in other clusters.

• Then what is the difference between classification and clustering?

The main difference is classification is used for labeled data, whereas clustering is used for non-labeled data(비지도 학습에 주로 사용)

• Where is clustering used?

• How can we determine the similarity or dissimilarity?

Clustering 의 핵심은 intra cluster distances는 최소화하고, inter cluster distances는 최대화하는 것이다
