Decision tree dependency measure

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :Sql Server
The dependency network viewer executes the stored procedure System.Microsoft.AnalysisServices.System.DataMining.DecisionTreesDepNet.DTGetNodeGraph which yields some integer measure that represents the strength of influence of input variables on the output variable. How this measures are calculated (information gain, chi-square, correlation etc)? It seems as if conditional influences are not taken into account: if A and B are two major factors which impact variable C, but A and B are strongly correlated so that C given A is not dependent on B, dependency algorithm will still depict B as the second major factor. Am I right? So there is no analogy of tests like conditional chi-square, conditional mutual information or partial correlation?   It seems to me that MS Data Mining lacks some kind of Bayesian Networks algorithm wich would illustrate conditional dependencies. That would give a useful insight on how various factors are related to each other and through what kind of chains a change in some input variable transforms to the output.   Thank you.

CASES & CONTENT of a Decision Tree Mining Model in One View


I would like to have a SQL view that presents both the CASES & CONTENT of the decision tree mining model in one view. Meaning - the view shall consist of the following fields: Node_Name, The Column to Predict, Unique Number (or Key) of a case, and input features of the case. Here is an example:

  Node_Name        | Key |   Column to Predict   | Input1 | Input2 | Input3 |...

0000000000101      |57|

0000000000101     |372|

0000000000100     |118|

0000000000100      |52|

0000000000100     |623|

000000000010000  |41|

000000000010000 |205|


I'm familiar with queries such as those:

FROM OPENQUERY(AnalysisServer,
'SELECT * FROM [MyMiningModel].Cases

FROM OPENQUERY(AnalysisServer,
AS Dmx

I wish that there was a way to present the information in one view.


How to assign 'Maximum Input Attribute' parameter for Decision Tree in SQL Sever 2005 in vba



I'm trying to assign the 'Maximum Input Attribute' parameter of the Decision Tree algorithm during forming a Mining Model in vba (see the code below). But I get an error message, that it is invalid for my Decision Tree. Is this parameter available only for bayesian networks or it appears only in version 2008 or am I doing something wrong?  Thank you very much in advance!

        TreeModel.AlgorithmParameters.Add("SPLIT_METHOD", intSplitMethod)
        TreeModel.AlgorithmParameters.Add("MAXIMUM_INPUT_ATTRIBUTE", 20)


Dependency Properties

When you begin to develop appliations with WPF, you will soon stumble across DependencyProperties. They look quite similar to normal .NET properties, but the concept behind is much more complex and powerful

Logical- and Visual Tree

Elements of a WPF user interface are hierarchically related. This relation is called the LogicalTree. The template of one element consists of multiple visual elements. This tree is called the VisualTree. WPF differs between those two trees, because for some problems you only need the logical elements and for other problems you want all elements.

May i use the collapse and expand feature (like tree menu) in Report ?


HI all,

May i use the collapse and expand feature (like tree menu) at Report iam using the Report viewer  Control for displaying the Report on my Asp.net Page .


I have number records and each record have detail as i clicked or expand the record then details will be shown is it possible with report viewer control 
If any one have experince before please share the ideas.

Design Patterns: Dependency Injection


Today there is a greater focus than ever on reusing existing components and wiring together disparate components to form a cohesive architecture. But this wiring can quickly become a daunting task because as application size and complexity increase, so do dependencies.

Custom tree view for navigating wiki pages

I'm creating an information resource on our intranet (WSS 3.0) using the wiki style format.  The only trick is, unlike a standard wiki, where all pages are directly under the parent, I want to be able to create a customizable tree view where some pages are nested underneath each other.  For example, this particular site talks about all of our different IT systems.  I'll have a wiki page for each system, then underneath each of those pages, there will be more pages for things like training, documentation, etc.  Even though all those pages are at the same level, I need to be able to nest them in a navigational tree view on the quick launch bar.  I suppose if there were also a way to nest the wiki pages themselves, I could just use the pre-packaged tree view.  Anyone have any ideas?

UserControl, CustomControl Design Time Support errors IOC, Dependency Injection, MVP

  Hi, is there a way to completely disable design time support for CustomControl, and UserControl ? I have about 30 UserControls and 10 CustomControls in my WinForms app, which contains some Dependency Injections and IOC stuff in constructors and Load handlers. I have lots of large UserControls containing smaller UserControls (CompositeView). All my UI code is pretty dynamic and the only thing i need to do at design time is to drag&drop containers in other containers (UserControls). And now i have a hard time doing this, because i have to wrap all constructors and Load Handlers in CurrentProccess!="devenv"... and when I'm Implementing some new View interface (which consist lots of properties) in UserControl all those properties by default throw NotImplementedException and i don't always need to implement them immediately but still i need to be able to run this code for testing. Besides, then i have to clean up designer generated class because it adds unnecessary null value property initializations, and then it way add some other ____ code, and so on.... Imagine UserControl with 10-15 nested UserControls, and then i try to open it in Form Designer and get ObjectReference NULL exception (for IOC) or some NotSupported NotImplemented exceptions (for properties) without adequate CallStack available! There is a CallStack but there is no trace in it to my Code (

display non measure, non dimension fields in drill down

Hi All, I created my fact table with more fields than just the foreign keys linking dimensions and the field(s) to be used as mesures.  I did this hoping that on drill down I would be able to see the extra fields so that the user would have access to detail information on the records making up the measure amount.  The extra fields do not appear on drill down.  How can I make them appear, or am I on the wrong track? Thanks for any help
