Applied Mathematics in Data Mining
Introduction
According to Suresh and Selvakumar (2014), data mining refers to the process of examining diverse perspectives and compiling it into more significant information. With the rapid growth of techniques, the data mining has been attracting various significant fields, such as business. Even though data mining is a novel term, technology isn’t, since organizations have utilized superior computers to filter large data amounts from supermarket scanners and examined market research reports over years. Regardless, technological advancements in computing with enhanced processors, disk capacities, and statistical software have raised the accuracy of analysis (Han, Pei, & Kamber, 2011). So organizations

In hard partitioning, an object is permitted to strictly belong to or not be part of a particular cluster. In contrary, soft hardening posits that each object belongs to a group in a predefined level. Distinct algorithms are used in every model, distinguishing its characteristics and outcomes, thus, enabling implementation of partitioning. The models are differentiated based on their organization and correlations, which are centralized, distributed, connectivity, group, graph, and density.
Problem Statement
In On-Line Analytical Processing (OLAP), the human analysts drive the analysis of data. Various challenges to data analysis facilitate the need for more intuitive and accurate methods to be deployed. First is the query formulation challenge in database systems, which presents the problem of data access whenever the user is oblivious of the way to illustrate the objective based on a particular query. For instance, an analyst handling large volumes of information is likely to demand a list of activities of concern available in the data. Although those trends are observable by humans on a one on one basis, they fundamentally challenge to define in SQL queries. Data mining builds a model of differentiating one group from another after the analyst, which has developed a set of cases of a particular group versus another and making it more feasible. Second, the growth
To begin with, Dell software an information technology enterprises describes Data Mining as “an analytic process designed to explore data in search of consistent patterns and/or systematic relationships between variables, and then to validate the findings by applying the
Data mining is essentially the ability to discover new information by exploring through various databases of existing information. According to Laura and Jack Cook, data mining "facilitates the discovery of previously unknown relationships among the data. …These operations present results that users already intuitively knew existed in the database."[2] As an example, let us take a school system consisting of three databases: one which stores the student profiles consisting of name and identification number, another to store student grades based on identification number, and the last one stores all the transactions at the bookstore through the student identification card. This is a simple example, but it should illustrate our point. Alone, the separate databases might not tell us much. With data mining techniques, the process might be able to tell us that in a particular school year, students of a certain ethnic background obtained above a 3.0 GPA, or that the bookstore sold mostly engineering books to students last year, or even that students who obtained above a 3.0 GPA were ones who bought engineering books. More specifically, the technology might be smart enough to associate that John Doe from Ireland had a 3.32 GPA in his engineering classes, even though he did not buy any engineering books from the bookstore. This type of technology is very powerful source of
The data analytic process is one in which a large amount of information is collected using software specifically geared towards collecting, identifying and storing information for use by the company. The information is gleaned from different forums, with social media being the most rich and useful. The information is then quickly sorted and organized for use by the collecting agency (Turban, Volonino, Wood, & Sipior, 2002, p. 6). The use of data analytics really took flight in 2010 when different companies offered software that enabled a company to implement their own data analytics. This led to better marketing campaigns, improved customer relations and it gave companies using the software a bigger advantage over their competitors (Savitz, 2012).
This article offers a view of the technical and non-technical requirements of making big data a successful endeavor for an organization. To achieve this goal the 10 step process if big data is defined, the data mining technologies are reviewed and data platform issues are briefly discussed.
Data mining is another concept closely associated with large databases such as clinical data repositories and data warehouses. However data mining like several other IT concepts means different things to different people. Health care application vendors may use the term data mining when referring to the user interface of the data warehouse or data repository. They may refer to the ability to drill down into data as data mining for example. However more precisely used data mining refers to a sophisticated analysis tool that automatically dis covers patterns among data in a data store. Data mining is an advanced form of decision support. Unlike passive query tools the data mining analysis tool does not require the user to pose individual specific questions to the database. Instead this tool is programmed to look for and extract patterns, trends and rules. True data mining is currently used in the business community for market ing and predictive analysis (Stair & Reynolds, 2012). This analytical data mining is however not currently widespread in the health care community.
Data mining software allows users to analyze large databases to solve business decision problems. Data mining is, in some ways, an extension of statistics, with a few
Data mining uses computer-based technology to evaluate data in a database and identify different trends. Effective data mining helps researchers predict economic trends and pinpoint sales prospects. Data mining is stored in data warehouses, which are sophisticated customer databases that allow managers to combine data from several different organization functions.
“Databases, Data Mining and Beyond” is the title of the article by Shamsul Chowdhurry. Professor Chowdhurry is a professor of Information Systems at Roosevelt University. The article focuses on case based reasoning, data mining and databases and their uses and application in various industries. First, let us define case based reasoning. Case based reasoning is a procedure to solve current problems by adapting solutions from past problems and applying it to the current problem to be solved. Case base database can be designed on case base reasoning. The structure of the database would have four steps. The steps include: 1) retrieval of similar cases; 2) adaptation; 3) evaluation and 4) update the case base. Each of the steps is a process that assists in the solving
In today’s society businesses accumulate all the data they can gather into the data warehouse, from which they can do data mining. This means that when we go to the grocery store and use our “saver card”, to get the tiny percent off, that store automatically tracks what you purchased and then enters it into their data warehouse. This allows the businesses to later go through that information and look for particular trends, seeing what products are popular what time of year, and as well as try figure what would we most likely to purchase. The art of looking through the data warehouse is referred to as data mining.
1) Data mining is a way for companies to develop business intelligence from their data to gain a better understanding of their customers and operations and to solve complex organizational problems.
An example of how data mining is conducted and used to benefit business can be explained in the following scenario:
The need to find a way to handle big data leads to data mining. Most researchers defined data mining similarly to Swain (2016). Swain described data mining as using technological processes to analyze big data and find unsuspected relationships among variables for future use. He continues to state that data mining technologies can find value from billions of gigabytes of data gathered from various sources. Huang, Lu, & Duan (2012) add to Swain’s definition by noting that, as opposed to typical statistical studies, data mining uses computational methods that allow the study to look
With the increased and widespread use of technologies, interest in data mining has increased rapidly. Companies are now utilized data mining techniques to exam their database looking for trends, relationships, and outcomes to enhance their overall operations and discover new patterns that may allow them to better serve their customers. Data mining provides numerous benefits to businesses, government, society as well as individual persons. However, like many technologies, there are negative things that caused by data mining such as invasion of privacy right. This paper tries to explore the advantages as well as the disadvantages of data mining. In addition, the ethical and global issues regarding the use of data mining
Today with the ever growing use of computers in the world, information is constantly moving from one place to another. What is this information, who is it about, and who is using it will be discussed in the following paper. The collecting, interpreting, and determination of use of this information has come to be known as data mining. This term known as data mining has been around only for a short time but the actual collection of data has been happening for centuries. The following paragraph will give a brief description of this history of data collection.
Every organization, be it a booming corporation, a start up non-profit, or even a national football league team, is comprised of a plethora of data. Although data has always been important to an organization, now more than ever it has become a critical part of their performance. With continuously advancing technology becoming available for companies to use, the amount of data accessible can seem almost endless. Figuring out how to manage this data, along with what to do with it can be a daunting challenge. This is where data analytics comes in. By simple definition, data analytics is the science of using the raw data collected to come to conclusions to make, hopefully, successful business decisions. There are many different facets of data analytics, and each facet can be uniquely important to an organization’s needs. Most data collected can be divided into one of three subgroups that each build upon the previous: descriptive, predictive, and prescriptive.
