An Overview of Data Mining Techniques Excerpted from the book by Alex Berson, Stephen Smith, and Kurt Thearling Building Data Mining Applications for CRM Introduction This overview provides a description of some of the most common data mining algorithms in use today. We have broken the discussion into two sections, each with a specific theme. Data mining techniques are more and more frequently used on numerical or structured data to discover new knowledge and the benefit of such techniques is well proven. However, knowledge captured in textual documentation is also a very valuable information source for any organization, but methods and tools to explore and exploit such data are less mature. 05/06/ · Data mining involves key steps which include problem definition, data exploration, data preparation, modeling, and evaluating and deployment . Using data mining techniques makes it Estimated Reading Time: 6 mins. Today data mining has become a vital role in all fields. This is because they discover interesting patterns and relationship in a data repository. Data mining is suitable for various fields such as image processing, artificial intelligence, machine.
There are four main types of data mining tasks: association rule learning, clustering, classification, and regression. There are two types of data: labelled and unlabelled. Labelled data has a specially designated attribute and the aim is to use the given data to predict the value of that attribute for new data. Unlabelled data does not have such a designated attribute. The first two data mining tasks, association rule learning and clustering, work with unlabelled data and are known as unsupervised learning.
The last two data mining tasks, classification and regression, work with labelled data and are called supervised learning.

Data mining is a process which deals with extraction of knowledge from databases. Data mining consists of numerous techniques to extract useful information from large files, without having any conceptualised notions about what can be discovered. Extracted information consists of patterns and relationships which were previously unknown. Data mining process is also called as „Knowledge Discovery in Databases“.
Data mining is a technique which deals with iteration and interaction. Business expertise were used jointly with new technologies to discover features and relationships in the data. By the use of business experience and expertise, useless information can also be transformed into valuable information. Data mining techniques can also be referred as „modelling“ or „machine learning“.
Data mining is used as an application in business community and it is supported by three technologies namely. Business transactions: Business industry consists of many transactions which is often „memorized“ for perpetuity.

Abstract:- Data mining is the process of discovering associations within huge data set, finding data patterns, anomalies, changes and significant statistical structures in the data. Conventional data analysis techniques involve formulating a hypothesis and then validating it against the dataset. On the other hand data mining techniques automatically detect significant patters in the data and these patterns can be used to formulate algorithms.
An important consideration in mining huge data sets is that the result or the pattern identified should be valid, understandable, useful and novel . Not to go without saying that data warehousing and maintaining large databases also principally rely on the efficiency of robust, intelligent and at times novel data mining techniques. Today data mining techniques are employed in nearly every sector of corporate industry.
From music industry to films maintenance, medicine to sports theres hardly any field of life without an input and integration of these data mining techniques. This paper focuses on presenting an overview of some of the most commonly used data mining techniques along with their applications. Techniques presented in this paper include sequence mining, clustering, classification, K nearest neighbors and association rule mining.
Additionally, theres a sample example in each case to help understand the basic working of each technique. Underlying branches, algorithms and process for each of these techniques are also given. Pseudo code for algorithms is also mentioned where required to ensure readers understanding with respective graphs.

Data Analysis is a process of inspecting, cleaning, transforming and modeling data with the goal of discovering useful information, suggesting conclusions and supporting decision-making. Several data analysis techniques exist encompassing various domains such as business, science, social science, etc. Data Mining is the analysis of large quantities of data to extract previously unknown, interesting patterns of data, unusual data and the dependencies.
Note that the goal is the extraction of patterns and knowledge from large amounts of data and not the extraction of data itself. Data mining analysis involves computer science methods at the intersection of the artificial intelligence, machine learning, statistics, and database systems. The patterns obtained from data mining can be considered as a summary of the input data that can be used in further analysis or to obtain more accurate prediction results by a decision support system.
Business Intelligence techniques and tools are for acquisition and transformation of large amounts of unstructured business data to help identify, develop and create new strategic business opportunities. The goal of business intelligence is to allow easy interpretation of large volumes of data to identify new opportunities.
It helps in implementing an effective strategy based on insights that can provide businesses with a competitive market-advantage and long-term stability. Statistics is the study of collection, analysis, interpretation, presentation, and organization of data. Predictive Analytics use statistical models to analyze current and historical data for forecasting predictions about future or otherwise unknown events.
In business, predictive analytics is used to identify risks and opportunities that aid in decision-making. Text Analytics, also referred to as Text Mining or as Text Data Mining is the process of deriving high-quality information from text.

An Overview of Data Mining Representation Techniques Abstract: Current data mining systems and techniques are used with the objective of finding future values for datasets, leaving aside what could be even more useful information, by not exploring deeper into the outputs of such techniques.
This paper presents an overview of the major representation and visualization techniques available and usable to bring forth all the potential associated with data mining techniques, especially those of a more complex nature, like artificial neural networks and support vector machines, with the objective of clarifying and raise awareness of the potential underlaying data mining techniques. The study uncovered a series of methods for this, such as a variety of techniques that help demonstrate artificial neural networks‘ visual model.

Organizations have access to more data now than they have ever had before. However, making sense of the huge volumes of structured and unstructured data to implement organization-wide improvements can be extremely challenging because of the sheer amount of information. If not properly addressed, this challenge can minimize the benefits of all the data.
Data mining is the process by which organizations detect patterns in data for insights relevant to their business needs. There are many data mining techniques organizations can use to turn raw data into actionable insights. These involve everything from cutting-edge artificial Intelligence to the basics of data preparation , which are both key for maximizing the value of data investments.
