2. Association – what could be linked together in away with something Patterns – sequential and time series, shows us how often certain things occur Classification – shows us how data is grouped

3. Prediction – the detection of a stable occurrence within the data that may continue into the future Identification – what can be found out by system usage or what might be present in a thing Classification – how the data could be grouped Optimization – finding ways to utilize resources

4. Apriori – frequent large item sets Sampling – small frequent item sets Frequent-Pattern (FP) Tree and FP-Growth – better version of Apriori Partition – efficient way to use the Apriori algorithm Decision Tree Induction – constructing a decision tree from a training data set k-Means – creates clustering And others

5. Marketing – analyzing customer behavior Finance – keeping track of credit and fraud Manufacturing – optimizing use of resources Health Care – checking patterns for useful information

7. We must create or use programs that shows us either a 2-D contingency table or a 3-D contingency table http://www.autonl ab.org/tutorials/dt ree18.pdf

8. We use a formula to decide which areas have the highest information gain dependent on what we would like to know. That forumula goes like this IG(Y|X) = H(Y) - H(Y | X) Where H(X) = the entropy of X
