Overview of Data Mining (Meaning and Process)

Large data-driven organizations inculcate a colossal amount of data. Today, the majority of data exists in raw form within these organizations. Moreover, organizations have been using techniques to process data and discovering business insights through it for ages.   

However, for organizations collecting a mammoth amount of data, some robust data processing techniques like Data mining for knowledge discovery of data (KDD) and processing data are a must.   

What is Data Mining? 

Data mining refers to a process involving the alteration and extraction of useful data patterns, trends, and relationships from huge raw data sets. Data mining helps to keep an insight over data analysis  

Data Mining amalgamate statistics with artificially intelligent algorithms to come across relationships and patterns from huge data sets.  

Furthermore, data mining involves numerous algorithms for transforming raw data in a valuable form. In addition, a robust method for processing data to enhance decision-making for organizations through the involvement of intuitive analysis of data with the help of machine learning.   

Moreover, data mining techniques are capable of sorting, filtering, altering, and cropping up valuable insights within large data sets. Organizations collect a mammoth amount of data in raw format, data mining helps bring the most crucial information to the front. 

Data Mining Process 

To begin with, the process of data mining is bipartite. The two parts include data preprocessing and data mining.    

Data Preprocessing 

The data preprocessing phase includes cleansing, combining, altering, and transforming data. In contrast, the data preprocessing phase is crucial for completely harnessing the data to drive success for data-driven organizations.   

In addition to this, some factors hamper the productivity of the process. These include; data preciseness, data constancy, data correctness, data completeness, and data delivery time. Besides, performing analysis on inaccurate and inconsistent data can never give accurate results. Hence, there is a strong need for data preprocessing. Data preprocessing stages include;             

Data Cleaning 

The first stage for preprocessing the data includes cleaning the data set. Without a doubt, data cleaning is crucial for preparing the raw form of data through the removal of unnecessary and repetitive data, filling in the missing values, and organizing the raw data. 

Data Integration 

The processed and clean data is still belonging to diverse sources like databases, data warehouses, etc. Data Integration involves bringing together useful and clean data for analysis to speed up the data mining process. 

Data Reduction 

Data reduction is about choosing pertinent data from the data set or data source. One of the ways to perform this process is through using a neural network. Furthermore, various approaches for performing data reduction like dimensionality reduction, numerosity reduction, and data compression.     

Data Transformation  

The transformation phase involves transforming the data into an admissible and sustainable format for improving the data mining process. Data transformation technique includes code generating process and data mapping.   

Data Mining  

The data mining phase involves data mining, assessing numerous patterns within processed data sets, and finally representing insights or knowledge for the data.   

Data Mining  

Data mining is used by large data organizations for figuring out business trends and generating business intelligence. However, data mining is purely dependable upon data collection and preprocessing for accuracy.   

During data mining, some business variables are set to determine patterns and relationships within the data using models for classification and methods for data clustering. 

Evaluation of Patterns    

This stage works upon utilizing the processed and clean data thoroughly. It goes through various patterns. Especially, when working with machine learning, neural networks, and GPU, building up multiple compelling patterns in real-time.    

Certain connections are built within the data to completely understand it through using methods like Data visualization and Data summarization.    

Representation of Knowledge    

The knowledge gathered and the data mined need to be represented in machine-understandable format. During this stage, we use tools like data visualization and knowledge representation.
