Clustering in Machine Learning Quiz

What is clustering in machine learning?

• A supervised learning technique

• A reinforcement learning technique

• A classification technique

Which of the following best describes a cluster?

• A collection of dissimilar objects grouped together

• A collection of data objects similar to one another within the same cluster

• A group of labeled data points

• A predefined set of classes

Which of the following is a common clustering algorithm?

• Decision Trees

• K-Means

• Q-learning

What is the main difference between partitional and hierarchical clustering?

• Partitional clustering groups objects into overlapping subsets, while hierarchical clustering does not
