Data mining tasks can, in general, be classified as tasks of d e s c r i p t i o n and p r e d i c t i o n [30], [24]. To understand the discovery goal, it is vital to understand the difference between descriptive and predictive tasks. Data mining technology is applied in …

2024年9月1日 · They have become a powerful tool for many data mining tasks in real world applica- tions and form a new development of data mining. 2 In addition, there is a wealth of data in the sphere of biomedicine from many sources. These available data come from clinical and laboratory sources, including disease phenotypes, omics data, physiological and ...

Clustering and pattern recognition is only one of the standard tasks considered in data-mining. Other data-mining tasks include regression, summarization, dependency modeling and change, and deviation detection. Clustering and pattern recognition are forms of classification problems that differ on an important characteristic.

2021年1月1日 · This chapter illustrates the intelligent data mining methods considering association rule mining (ARM) and the Apriori algorithm to mine information from the dataset. In addition, the data mining functionalities are employed to specify the type of patterns to be found using the data mining tasks.

2012年10月1日 · Knowledge Discovery and Data Mining process models provide prescriptive guidance. They describe ‘how to’ implement the complex and iterative Data Mining project. Quality of process model selected, affects the overall outcome of the project. We evaluate IKDDM process model and compare it to CRISP-DM, a leading process model. IKDDM is more effective and efficient in executing tasks of Data ...

1997年11月1日 · Data mining is a step in thKDD process consist- ing of applying computational techniques that, under acceptable computational efficiency limitations, pro- duce a particular enumeration of pattems (or models) over thdata [7, Chap. 1] Note that thspace of pattems is often infinit and thenumeration of pattems involves some form of search in mis space.

2020年1月1日 · Data mining tasks are generally divided into two broad categories: descriptive and predictive (Rokach and Maimon, 2015; Tan et al., 2006). Descriptive data mining tasks are often exploratory. Their objective is to identify correlations, associations, clusters, patterns, and anomalies that summarize the underlying relationships in the database.

2018年1月1日 · In addition, a lot of resources and time spent on the choice of the model and its training. 2 Data Mining Tasks There are the following categories of Data Mining problem solving: supervised learning (with teacher training) and unsupervised learning (learning without a teacher). The term comes from Machine Learning.

2009年11月1日 · Spatial data mining encompasses various tasks and, for each task, a number of different methods are often available, whether computational, statistical, visual, or some combination of them. Here we only briefly introduce a selected set of tasks and related methods, including classification (supervised classification), association rule mining ...

2017年2月1日 · Furthermore, 85% of the data mining applications in financial accounting and AIS focused on only two data mining tasks, classification (50%) and clustering (35%), highlighting a potential opportunity for more utilization of the many other data mining tasks, such as visualization (a form of exploration), in the applications of data mining in ...
