Essay on The Challenges faced During Data Mining

Data mining is an act that entails releasing fascinating facts that are usually gathered from huge databases logs, data warehouses, anomalies, important structures, associations, changes and patterns among others (Galloway and Sminoff 3). Although to a researcher data mining might be a tool that entails database awareness ventures, to others it is a major step in awareness discovery. The focus of this paper is on the evaluation of challenges that data miners face.

In practice, the main data mining goals are usually prediction and description (Gianella, Bhargawa and Kargupta 4). Description entails analyzing human-interpretable which elaborates data. Prediction on the other hand entails the use of certain variables or fields in the database in prognosticating the interested variables’ future utility. These high levels are achieved through the application of major errands in data mining. The first errand is classification. This is the process via which the outcome that categorizes data of any article into different presumed classes is examined. The second errand is regression. This is the outcome’s leaning process during which a data article is classified to a presumption variable that has real value.

The third errand is clustering. This is a common task of depiction during which a person aims at differentiating a restricted clusters’ set in order to elaborate the gathered data. The fourth errand is summarization. This entails the techniques via which solid data subset elaboration is acquired. The fifth errand is dependency modeling. This entails discovering the model that indicates the vital dependencies that link variables. This errand has a structural level in which variables rely on one another locally. It also has a quantitative level which indicates the dependencies’ weight through the use of a specific numerical scale. Deviation detection and change are the last errands in data mining. These focus on providing vital data changes from the values measured initially (Gianella, Bhargawa and Kargupta 4).

Theories that explain Unified Data Mining formulation are either shallow or detailed. However, in terms of science, a good theory elaborates details in the scientific disciplines. Physicists contend that there are several forces that influence substances globally (Gianella, Bhargawa and Kargupta 45). They include strong force, electromagnetic force, weak force and gravitational force. A unified theory comprises of comprehensives, preciseness, essentials, consistency and correctness. For the unification parts of a theory to be understood fully, there are various intentions that should be considered as well as their inventors. Sir Isaac Newtown discovered the mechanism of a unified theory in 1687. This mechanism explains earthly and heavenly movements. John Dalton revived the atomic theory that explains substances’ physical nature (Yang 46).
