\"DATA<\/a><\/p>\n

Data mining means extracting or ‘mining’ knowledge from raw data. It is a process of analyzing data from different perspectives and summarizing it into useful information to increase revenue of an enterprise etc.<\/p>\n

Joseph P. Bigus in his book “DATA MINING AND NEURAL NETWORKS ” define data mining as ‘data mining is the efficient discovery of valuable, non obvious information from a large collection of data’.\u00a0<\/em><\/strong><\/p>\n

Data mining is also referred to as knowledge discovery process.<\/p>\n

Steps in knowledge discovery process are following:-<\/strong><\/p>\n

1. Determination of business objectives.<\/p>\n

2. Selection and preparation of data.<\/p>\n

3. Application of suitable data mining techniques.<\/p>\n

4. Evaluation and application of results.<\/p>\n

Also, some major data mining techniques are:-\u00a0<\/strong><\/p>\n

A) CLUSTER DETECTION:<\/p>\n

In this technique the cluster detection algorithm searches for groups or clusters of data elements that are similar to one and another.<\/p>\n

B) DECISION TREES:<\/p>\n

This technique applies to classification and prediction. Decision trees represent rules. We can use these rules to retrieve records falling into a certain category. It is a series of questions. Each question determines what follow up question is best to be asked next.<\/p>\n

C) LINK ANALYSIS:<\/p>\n

This algorithm is extremely useful for finding patterns from relationships. Thus technique mines relationships and discover knowledge.<\/p>\n

D) ASSOCIATION DISCOVERY:<\/p>\n

Associations discovery algorithms find combinations where the presence of one item suggests the presence of another.<\/p>\n
