________ - ANSWERS✔-inbound logistics
\.Streamtech, a manufacturer of automobiles, recently received a patent for an
unmanned search boat. By doing this, Streamtech has ________ - ANSWERS✔-
introduced product differentiation
\.______ is the extraction of knowledge from data based on algorithms created
fromtraining data. - ANSWERS✔-machine learning

________ data - ANSWERS✔-previously known training
, \.A sales report that is current at the time the user accessed it on a Web server is
an example of a(n) ________ - ANSWERS✔-dynamic or exception report
\.Differentiate between unsupervised and supervised data mining - ANSWERS✔-
Data mining techniques fall into two broad categories: unsupervised and
supervised.With unsupervised data mining, analysts do not create a model or
hypothesis before runningthe 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 patternsfound. With
supervised data mining, data miners develop a model prior to the analysis
andapply statistical techniques to data to estimate parameters of the model.
\.Which of the following is an example of a supervised data mining technique -
ANSWERS✔-regression analysis
\.What is the difference between cluster analysis and classification? - ANSWERS✔-
Cluster analysis groups data according to their similarities (that we don't
knowbeforehand), and classification predicts output categories based given input
data (weknow the data is labeled). Classification is supervised learning and cluster
analysis is unsupervised learning
\.An OLAP report has measures and dimensions. Which of the following is an
example of adimension? - ANSWERS✔-sales region
\.A ________ is a person or an organization that seeks to obtain or alter data or
other IS assets illegally, without the owner's permission and often without the
owner's knowledge - ANSWERS✔-threat
