1.A classification model (in PMML format) was created by a third party vendor tool such as SPSS. After importing the model into DB2, where is it stored?
A.In a user-specified table . under an automatically generated name, e.g. SPSS_017.
B.In the table IDMMX.CLASSIFMODELS under a user-specified MODELNAME. The default is the value of the attribute "modelname" in the PMML TreeModel.
C.In the table .CLASSIFMODELS under a user-specified MODELNAME. The default is the value of the attribute "modelname" in the PMML TreeModel.
D.In a user-specified table . under a user-specified MODELNAME. The default is the value of the attribute "modelname" in the PMML TreeModel.
Correct:B
2.Which of the following must be fulfilled to execute a mining flow that creates a classification model in the database?
A.All input and output ports of all operators must be connected.
B.The flow must contain a Predictor operator whose properties define a Cost Matrix.
C.The flow must contain a Predictor operator whose output port must be connected to a Visualizer.
D.The flow must contain a Predictor operator whose properties (Mining Settings) define a categorical target column.
Correct:D
3.Application data changes over time and differs from that used to train a classification model M. Assume that a mining flow with a Tester operator with M and the application data as input and a test model T as output has been defined. What must be done to check if M can still safely be applied?
A.Open T in a visualizer and check the tree depth. If the tree depth is greater than 10, the model is OK.
B.Open T in a visualizer and check the model quality figures. If the quality is greater than 0.5, the model is OK.
C.Open M and T in a visualizer and check the tree depth. If the tree depth of T is greater than the tree depth of M, the model is OK.
D.Open M and T in a visualizer and check the model quality figures. If the quality is about the same as the quality of M, the model is OK.
Correct:D
