Data Mining

The data mining is the technique in which useful information is extracted from the raw data. The data mining is applied to accomplish various tasks like clustering, prediction analysis and association rule generation with the help of various Data Mining Tools and Techniques. In the approaches of data mining, clustering is the most efficient technique which can be applied to extract useful information from the raw data. The clustering is the technique in which similar and dissimilar type of data can be clustered to analyze useful information from the dataset. The clustering is of many types like density-based clustering, hierarchical clustering, and partitioning based clustering. The k-mean algorithm is the most efficient algorithm which is widely used to cluster similar and dissimilar types of data from the input data set. In the k-mean clustering, the centroid point is calculated by taking the arithmetic mean of the input dataset. There are various hot topics in Data Mining to do research and for thesis.

  • Data exploration – Required data is collected and explored using various statistical methods along with identification of underlying problems.

  • Data preparation – The data is prepared for modeling by cleansing and formatting the raw data in the desired way. The meaning of data is not changed while preparing.

  • Modeling – In this phase the data model is created by applying certain mathematical functions and modeling techniques. After the model is created it goes through validation and verification.

  • Evaluation – After the model is created, it is evaluated by a team of experts to check whether it satisfies business objectives or not.

  • Deployment – After evaluation, the model is deployed and further plans are made for its maintenance. A properly organized report is prepared with the summary of the work done.
