Question

what are the categories of data mining tasks

Answer 1

The main categories of data mining tasks are -

• Concept description
• Association rule mining
• Classification and prediction
• Cluster Analysis

Concept Description

In this data mining task, descriptions for characterization and comparisons of the data are generated.

Association Rule Mining

Here, interesting associations or correlation relationships among a large set of items are searched.

Classification and Prediction

Categorial labels are predicted by classification while continuous functions are modelled by prediction. These methods are also called supervised learning algorithms since the class labels are known.

Cluster Analysis

The process by which data are grouped into classes or clusters so that objects with high degree of similarity are within a cluster is known as clustering. The main goal of clustering is to maximize intraclass similarity and minimize interclass similarity.
