Differentiate between unsupervised and supervised data mining.
Data mining techniques fall into two broad categories: unsupervised and supervised.
With unsupervised data mining, analysts do not create a model or hypothesis before running
the analysis. Instead, they apply a data mining application to the data and observe the results.
With this method, analysts create hypotheses after the analysis, in order to explain the patterns
found. With supervised data mining, data miners develop a model prior to the analysis and
apply statistical techniques to data to estimate parameters of the model.
Which of the following is an example of a supervised data mining technique?
A) cluster analysis
B) market-basket analysis
C) regression analysis
D) click streaming
E) metadata matching
C. regression analysis

B) cluster analysis
C) neural networks
D) market-basket analysis
E) unsupervised learning
D. market-basket analysis
What is the difference between cluster analysis and classification?
Cluster analysis groups data according to their similarities (that we don’t know
beforehand), and classification predicts output categories based given input data (we
know the data is labeled).
Classification is supervised learning and cluster analysis is unsupervised learning.
