Question

What are the three critical issues when solving a data mining problem using MBR?

a.

Decision tree structure, distance function, and combination function

b.

Historical records, decision rules, and unknown instances

c.

Training dataset, composition of historical record, and distance function

d.

Decision tree effectiveness, pruning, and predictive accuracy

Answer: (c).Training dataset, composition of historical record, and distance function Explanation:The three critical issues when solving a data mining problem using MBR are selecting the most suitable historical records for the training dataset, establishing the best way to compose the historical record, and determining the distance function and combination function.
