Data Exploitation, including Data Mining and Data Presentation, which corresponds to Fayyad, et al.’s last three steps. Source Selection is process of selecting sources to exploit. Source selection requires awareness of the available sources, domain knowledge, and an understanding of the goals and objectives of the data mining effort. CHAPTER-8 DATA MINING TASKS INTRODUCTION The goal of any data mining effort can be divided in one of the following two types (Cha & Lweis, ): [22]. Using data mining to generate descriptive models to solve problems. Using data mining to . Data Mining Task Primitives We can specify the data mining task in form of data mining query. This query is input to the system. The data mining query is defined in terms of data mining task primitives. Note: Using these primitives allow us to communicate in interactive manner with the data mining .

Data Mining Tasks - Learn Data Mining in simple and easy steps starting from basic to advanced concepts with examples Overview, Tasks, Data Mining, Issues, Evaluation, Terminologies, Knowledge Discovery, Systems, Query Language, Classification, Prediction, Decision Tree Induction, Bayesian, Rule Based Classification, Miscellaneous Classification Methods, Cluster Analysis, Mining Text Data. Data mining can be used to solve hundreds of business problems. Based on the nature of these problems, we can group them into the following data mining tasks. Classification Classification is one of the most popular data mining tasks. Business problems like churn analysis, risk management and ad targeting usually involve classification. View Data mining foroconstituyente.info from SPMS MAS MH at Nanyang Technological University. CREDIT TO YANG ZHOU MH Data Mining Lecture 1 (26th, July) Introduction Definition of Data Mining Author: Yangzhouzhou. Preliminaries Data Mining Tasks 2 The objective of these tasks is to predict the value of a particular attribute based on the values of other attributes. The attribute to be predicted is commonly known as the target or dependent variable, while the attributes used for making the prediction are. While many data mining tasks follow a traditional, hypothesis-driven data analysis approach, it is commonplace to employ an opportunistic, data driven approach that encourages the pattern detection algorithms to find useful trends, patterns, and relationships. Essentially, the two types of data mining approaches differ in whether they seek to build.

In: Introduction to Data Mining and its Applications. Studies in Computational Intelligence, vol Data Mining Algorithms “A data mining algorithm is a well-defined procedure that takes data as input and produces output in the form of models or patterns” “well-defined”: can be encoded in software “algorithm”: must terminate after some finite number of steps Hand, Mannila, and Smyth. Data Mining Task Primitives We can specify the data mining task in form of data mining query. This query is input to the system. The data mining query is defined in terms of data mining task primitives. Note: Using these primitives allow us to communicate in interactive manner with the data mining .

Objectives: • To compete effectively in today's marketplace, business managers must take timely advantage. PDF | This paper deals with detail study of Data Mining its techniques, tasks and related Tools. Data Mining refers to the mining or discovery of new information. Data Mining - Tasks. Introduction. Data Mining deals with what kind of patterns can be mined. On the basis of kind of data to be mined there are two. The data mining tasks can be classified generally into two types based on what a specific task tries to achieve. Those two categories are descriptive tasks and. the data in the database, while predictive data mining tasks perform inference o the current data in order to make prediction. Descriptive data mining focus on. Preliminaries. Data Mining Tasks. 2. The objective of these tasks is to predict the value of a particular attribute based on the values of other attributes.
