Data Mining Tools

Introduction to Data Mining Tools :

Data mining is defined as a process used to extract usable data from a larger set of any raw data which implies analysing data patterns in large batches of data using one or more software.

Data mining is the process of discovering patterns in large data sets.

Data mining is the analysis step of the “knowledge discovery in databases” process, or KDD.

Brief Introduction of Data Ming Tasks

There are several data mining tasks such as classification, prediction, Outlier detection, clustering, Regression and Decision Tree etc. All these tasks are either fall in predictive data mining tasks or descriptive data mining tasks. A data mining system execute one or more tasks as part of data mining.

  1. Classification
  • Classification technique is used for assigning the items into target categories or classes which is used to predict what will occur within the class accurately.
  • It classifies each item in a set of data into one of a predefined set of classes or groups.
  1. Outlier Detection

Outliers is defined as the data objects that do not comply with the general behaviour or model of the data available.

  1. Clustering

Cluster analysis is one of the techniques of data mining by which related records are grouped. As a result, objects are like one another within the same group. Although, they are different in same or other clusters.

  1. Regression

This technique is used for establishing the dependency between the two variables so that causal relationship can be used to predict the outcome.

  1. Prediction

Prediction is made by finding the relationship between independent and dependent variables.

  1. Decision Trees
  • Decision tree is one of the analytical technique of Data Mining.
  • This technique is used for categorising or predict data.
