Data Mining: Unleash the Power of Your Data

Data mining is a process that allows businesses to analyze large amounts of data to make better decisions. From consumer internet companies like Facebook to those in finance and retail rely on data mining. 

Using big data analysis software, businesses can learn more about their customers’ buying habits and preferences. By collecting as much data as possible from every interaction, these companies can gather valuable information about what customers want. This helps companies to offer personalized products and services. 

For example, A clothing store might use big data to figure out which outfit a particular consumer prefers, what size they prefer, and how often they buy things.

Data mining process

Following are seven stages of the Data mining process – 

• Data cleaning

Before beginning data mining, it’s important to have a clean set of data. This may sound obvious, but sorting out data inconsistencies, detecting and correcting errors in data sets takes time because it requires a lot of attention to detail as well as knowledge about how the data set was collected and processed. 

Some types of errors include missing values, formatting issues, outliers, and inconsistent values across different variables. Data cleaning is an important process to ensure that data is accurate and reliable for analysis, especially when it is used to create statistical models. If it is in any way imperfect it will impact the outcome. 

• Data Integration

Raw data is collected from different platforms. This could be an overwhelming amount of information. To simplify, there must be data integration through various tools that make sense of different sources of raw data. 

Data integration brings data from different sources together. This can be done to combine datasets that have the same variables or to join datasets that have similar but not identical variables. Eventually, all multiple sources would lead to a single analytics view on specific topics. 

• Data Reduction 

Data mining requires a significant amount of historical data, but data repositories include far more data than is required for the process. As a result, necessary data is selected from the integrated data.

This step involves reducing the size of data by removing unnecessary or redundant data. Depending on the dataset, there may be many unnecessary variables. Which has to be removed before proceeding to the further step. 

• Data Transformation

In the data transformation stage, data is converted into different formats suitable for data mining. Data mapping and other data science techniques are included in this process. Data transformation steps involve smoothing, aggregating, discretization, generalization, normalization and attribute Construction of the data.

• Data Mining

This is a crucial stage in data mining, where patterns and knowledge from a large amount of data are extracted by applying intelligent patterns to the data.

• Pattern Evaluation

Pattern evaluation is carried out by spotting useful and interesting patterns. The evaluation indicates information based on which patterns are interesting and the score of each pattern, then summarizing and visualizing the data in a user-friendly format.

• Knowledge Representation

In the last stage, the data is visualized in the form of reports, tables, etc to represent mined data.
