Overview of the Data Mining Process
The data mining process is mainly done to get the pattern and probabilities from the large dataset due to which it is highly used in business for forecasting trends; along with this, it is also used in fields like Market, Manufacturing, Finance, and Government to make predictions and analysis using the tools and techniques like R-language and Oracle data mining, which involves the flow of six different steps.
One of the essential tasks of data mining relates to the automatic and semi-automatic analysis of large quantities of raw data and information to extract the previously unknown exciting set of patterns such as clusters or a group of data records, anomaly detection (unusual forms), and also in the case of dependencies which makes use of sequential pattern mining and association rule mining. This makes use of spatial indices. Anyone can identify these patterns as some of the types present in the input data and utilize them for further analysis, such as predictive analysis and machine learning. Incorporating support decision systems enables you to obtain more specific sets of results.
How does Data Mining Work?
Data are abundant in the industry across domains, and treating and processing the data accordingly becomes essential. Basically, in a nutshell, it involves the ETL set of processes, such as the extraction, transformation, and loading of the data and everything else required for this ETL to happen. This involves data cleansing, changing, and processing in various systems and representations. The clients can use this processed data to analyze the businesses and the growth trends in their companies.
The advantage of data mining includes the ones related to business and ones like medicine, weather forecast, healthcare, transportation, insurance, government, etc. Some of the advantages include the following:
- Marketing/Retail: Marketing companies and firms can build models based on historical data and information to predict the responsiveness to today’s marketing campaigns, such as online marketing campaigns, direct mail, etc.
- Finance/Banking: Data mining involves financial institutions providing information about loans and credit reporting. Financial institutions can determine good or bad loans by building the model on historical information. Additionally, banks monitor fraudulent and suspicious transactions.
- Manufacturing: Using the optimal parameters for controlling can determine the faulty equipment and the quality of the manufactured products. For example, for some semiconductor development industries, water hardness and quality become a significant challenge as they affect the quality of their product’s production.
- Government: Monitoring and gauging suspicious activities can benefit governments in preventing anti-money laundering activities.
Different Stages of Data Mining Process
The different stages of the data mining process are as follows.
- Data cleansing: This is the initial stage in data mining, where data classification becomes essential to obtaining final data analysis. It involves identifying and removing inaccurate and tricky data from a set of tables, databases, and record sets. Some techniques include ignoring tuples, especially when the class label is missing; the following approach requires filling the missing values on its own and replacing missing and incorrect values with global constants or predictable or mean values.
- Data integration: It is a technique that involves merging the new information set with the existing group. The source may involve many data sets, databases, or flat files. The customary implementation for data integration is creating an EDW (enterprise data warehouse), which then talks about two concepts- tight and loose coupling, but let’s not dig into the details.
- Data transformation: This requires transforming data within formats, generally from the source system to the necessary destination system. Some strategies include Smoothing, Aggregation, Normalization, Generalization, and attribute construction.
- Data discretization: Data discretization is the technique that can split the continuous attribute domain along intervals. We store the datasets in small chunks, which makes our study much more efficient. Two strategies involve Top-down discretization and bottom-up discretization.
- Concept hierarchies: They minimize the data by replacing and collecting low-level concepts from high-level concepts. Concept hierarchies define multi-dimensional data with multiple levels of abstraction. The methods are Binning, histogram analysis, cluster analysis, etc.
- Pattern evaluation and data presentation: The client and the customers can best use the data if presented efficiently. After going through the above set of stages, the data is presented in graphs and diagrams, enabling them to understand it with minimum statistical knowledge.
Tools and Techniques
The process of data mining involves using tools and techniques to extract and effectively utilize data. The following two are among the most popular set of tools and techniques for data mining:
- R-language: It is an open-source tool used for graphics and statistical computing. It has various classical statistical tests, classification, graphical techniques, time-series analysis, etc. It makes use of adequate storage facilities and data handling.
- Oracle data mining: Oracle has integrated ODM into its advanced analytics database, enabling it to generate detailed insights and predictions that can specifically detect customer behavior, develop customer profiles, and identify cross-selling opportunities.
Data mining is about explaining historical data and an actual streaming data set, using predictions and analysis on top of the mined data. It is closely related to data science and machine learning algorithms such as classification, regression, clustering, XGboosting, etc., as they tend to form essential data mining techniques.
One of the drawbacks can include training resources on software, which can be a complicated and time-consuming task. Data mining has become a necessary component of one’s system today, and by making efficient use of it, businesses can grow and predict their future sales and revenue. I hope you liked this article.
