Cluster Is (Data Mining MCQ)

Cluster Is

1A cluster is a subset of similar objects
2A subset of objects such that the distance between any of the two objects in the cluster is less than the distance between any object in the cluster and any object that is not located inside it.
3A connected region of a multidimensional space with a comparatively high density of objects.
4All of these

Answer: D

Explanation:

What is a Cluster?
  • A cluster is a subset of similar objects
  • A subset of objects such that the distance between any of the two objects in the cluster is less than the distance between any object in the cluster and any object that is not located inside it.
  • A connected region of a multidimensional space with a comparatively high density of objects.
What is clustering in Data Mining?
  • Clustering is the method of converting a group of abstract objects into classes of similar objects.
  • Clustering is a method of partitioning a set of data or objects into a set of significant subclasses called clusters.
  • It helps users to understand the structure or natural grouping in a data set and used either as a stand-alone instrument to get a better insight into data distribution or as a pre-processing step for other algorithms.

FAQ

What is a cluster in data mining?

Clustering in Data Mining. Clustering is an unsupervised Machine Learning-based Algorithm that comprises a group of data points into clusters so that the objects belong to the same group. Each of these subsets contains data similar to each other, and these subsets are called clusters.

What is a cluster in it?

A cluster is a group of inter-connected computers or hosts that work together to support applications and middleware (e.g. databases). In a cluster, each computer is referred to as a “node”. Unlike grid computers, where each node performs a different task, computer clusters assign the same task to each node.

What is a cluster in data mining MCQ?

The term “cluster” refers to the set of similar objects or items that differ significantly from the other available objects.
