Decision Trees - significance of Node_Description features

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :Sql Server

Let's say that I have one node in my decision tree with a Node_Description that looks like that:

InputParameterA >= 10 and InputParameterB not = 'True' and InputParameterC < 10 and InputParameterD >= 120 and < 150

Is there a way to know what is the importance of each of the four input parameters?

For example, a potential answer might be "InputParameterA" contributed 32%, "InputParameterB" contributed 2%, "InputParameterC" contributed 10%, and "InputParameterD" 56%. Such an answer will clarify that "InputParameterA" and "InputParameterD" are more important.

Decision Trees & DMX


I need to query a decision tree mining model for three pieces of information:

1) For a given prediction query, how can I tell what node is used to generate the result?

2) Which training cases belong to that node?

3) Which node does a given training traing case belong to?

Any help that you can offer would be greatly appreciated.


Thanks in advance,


Learning Bayesian Networks for building Decision Trees


In MSDN article Microsoft Decision Trees Algorithm Technical Reference is said "The Microsoft Decision Trees algorithm learns Bayesian networks..". It seems to me that BN and DT are very different tasks and approaches to data modelling. The question is: how learned Bayesian network (which models joint distribution considering some conditional independencies) is used further to build decision tree?
