Data Mining
Data Miningis a process of examining patterns of large sets of data by using various techniques like machine learning, statistics, and database system to extract meaningful outcome. By inspecting and collecting data, pattern is discovered through Data Mining.
In simple words, raw data is collected by companies and by data mining, raw data is turned into useful information. There are several types of Data Mining:
· Pictorial Data Mining
· Text Mining
· Social Media Mining
· Web Mining
· Audio Mining
· Video Mining
Data mining process: Data Mining is process to identify patterns from large amount of data. Following are steps involved in Data Mining
1. Data Cleaning: In this step, data is cleaned, incomplete data is removed as it can leads to poor insights or failure. So, data is cleaned as with industry standards.
2. Data Integration: In this, data miners combine different data sets to perform analysis. This eliminates any inconsistent information.
3. Data Reduction: Data reduction refers to extracting relevant information for data analysis and pattern evaluation. Engineers reduce he data and relevant data is left for analytics purpose.
4. Data Transformation: In this, data is transformed into acceptable form to align with mining goals. It encompasses data mapping, eliminating noise from data, normalization etc.
5. Data Mining: Data Mining is done by all organization to extract useful information and pattern to generate solution to any problem. Specialists uses clustering, classification etc. for data mining step.
6. Pattern Evaluation: In this, pattern is studied that can generate business knowledge. Team summarize information to make it easier to understand.
7. Representing Knowledge: At last, data analysts shares information with others by using various techniques like reports, mining tools etc. Data is represented to owners and other parties in final product which can be understood by them easily.
Techniques of Data Mining:
There are several techniques that are used in Data Mining to extract useful result from raw data. These are:
· Classification:In Classification, items are classified in a data set into different classes. It classifies items in a data set into predefined groups. It uses linear programming, statistics, decision trees etc.
· Clustering: Clustering technique determine object groupings such that objects or items of same cluster form one group or items of similar nature form one group. Clustering is used in market segmentation, example Library where books of same subjects are kept in one shelves, so, that readers don’t face difficulty in finding particular subject books.
· Prediction: Prediction techniques is also called regression techniques. In this, prediction power is used to predict the relationship between independent and dependent variables. This techniques are very useful in data science and is most simple technique.
· Association Rule Discovery: It is most used data mining technique in which transaction and relationship between all its items are used to identify pattern. This technique is very useful to study consumer behavior.
Application of Data Mining: Although data mining is used in all sectors but here are few of them listed below:
1. Telecom Industry: Telecom industry is growing at fast pace, data mining can help industry to improve quality service. Techniques can be used to analysis fraudulent users, pattern analysis for spatiotemporal data etc.
2. Retail Industry: The retail sector hold major position in market and required data related to sales, purchases, delivery of goods, customer service etc. Data mining can be used to analysis buying patterns, improving customer service etc.
3. Education Industry: Education is one of the most important and high demand sector that are looking for unique solutions to fulfill today’s needs. Data mining can be used to examine student’s behavior and predict which students will enroll for which program etc.
4. Criminal Investigation: Data mining can be used for studying crimes characteristics, which will help in making easy procedure for criminal investigation.
5. Financial Sector: Banking and financial sector are backbone of any economy. Data mining is used in these sectors to determining credit ratings, predicting loan payments, investment pattern etc. Data mining can make these tasks more manageable.
6. Counter-Terrorism: Data mining can be used to help defense sector and police administration tasks also, to counter terrorism like where to deploy the workforce etc.
Other sectors like Biological data analysis, spatial data mining, energy industry, manufacturing unit, farming, science and engineering etc. where data mining can convert administration tasks manageable. Data mining has become important part for all sectors and organization.
Why Data Mining Has Become Important?
As, data has become expensive asset for all organization to be ahead from their competitors. Data is increasing day-by-day which have made it difficult to manage. So, here comes data mining which convert this data into meaningful information. By applying patterns and classification, useful insight can be extracted from it and essential decision can be made out of it. This is the reason why data mining has become important and popular over the time.
Lastly, data mining is important component for all organization and if you want to learn how useful information are extracted from raw data using various techniques, data science is field to study. Data Mining is important element of data science.
