When describing data, which two nodes address value types? (Choose two.)

• A.Data Audit node
• B.Report node
• C.Type node
• D.Statistics node

An e-retailer conducting a data mining project has limited an initial study to approximately 30,000 customers who have registered on the site. There are still millions of records in the Web logs. The data miner wants to determine the frequency distribution of the age of their customers. The Age column is acontinuous field.
Which node would you use to accomplish this task?

• A.Histogram node
• B.Sim Fit node
• C.Transform node
• D.Report node

Which statement is correct about the Reclassify node?

• A.The Reclassify node can be used to reduce the number of records (rows) in the data.
• B.The Reclassify node automatically creates new nominal fields based on the values of one or more existing continuous (numeric range) fields.
• C.The Reclassify node can be used to reduce the number of fields (columns) in the data.
• D.The Reclassify node enables the transformation from one set of categorical values to another.

You have executed a model node which has generated a model nugget connected to your stream's data source.
What will allow the stream to score data with this new nugget?

• A.Remove the Reclassify node to use the nugget model for scoring.
• B.Remove any partition node to allow all data to be scored.
• C.Add an output node downstream from the nugget.
• D.Add a Discriminant node to use the nugget model for scoring.

You have optimized four models that do not meet your performance goals. You believe that by mergingthese models together you would achieve better performance.
Which node would allow you to accomplish this task?

• A.Aggregate node
• B.Regression node
• C.Ensemble node
• D.Reclassify node
