Question

All of the following statements about data mining are true EXCEPT Select one: a. the valid aspect means that the discovered patterns should hold true on new data. b. the potentially useful aspect means that results should lead to some business c. the novel aspect means that previously unknown patterns are discovered. d. the process aspect means that data mining should be a one-step process to benefit. results

Answer 1

Answer:

The correct option is D: The process aspect means that data mining should be a one-step process to result

Explanation:

Data mining is known the process of discovering correlations, patterns, and anomalies within a huge data set in a bid to predict outcomes or result. There are several features of data mining. The first one is that the valid aspect of data mining entails that on new data, the discovered pattern should be true, and hence A is a correct statement. Furthermore, it is true that when the data is potentially useful, this means that it is capable of leading to some form of business. Lastly, the novel aspect entails there are some unknown patterns that have been uncovered. The process aspect include processes such as, understanding the business, understanding the data, preparing the data, modeling, evolution, before deployment, hence, this is not a one-step process to result.

Answer 2

Answer:

The answer is D. the process aspect means that data mining should be a one-step process to results.

Explanation:

Data mining can be defined as the generation of new information, discovering new patterns through examining patterns in large pre-existing database. The process aspect of data mining is not a one-step process to results as it includes numerous tasks such as association, classification, prediction, time series analysis, etc.
