I'm in trouble with my Plug-in Algorithm while filling out my model rowsets.
How to return ATTRIBUTE_NAME through GetNodeProperty if does not exist an ID to do it? Also it appears that no call is made for retrieve such node property.
Thanks

Hi,
i'm making my master thesis about a new plug-in algorithm, with the LVQ Algorithm.
I make the tutorial with the pair_wise_linear_regression algorithm and i have some doubts. i was searching for the code of the algorithm in the files of the tutorial and i didn't saw it. I have my new algorithm programmed in C++ ready to attach him, but i don't know where to put him, in which file i have to put him to start to define the COM interfaces? And in which file is the code of the pair_wise_linear_regression algorithm in the SRC paste of the tutorial?
Thanks
I have installed the plug-in on two different virtual machines. On one, everything works fine, but on the other, the plug-in does not seem to load when Excel starts. I can see the plug-in the "Inactive Application Add-ins" section of the Excel Option Add-Ins panel, but when I check the two Add-in options in the "Manage Add-ins" dialog, they do not move up to the "Active" section. Stopping/starting Excel does not resolve the issue.
Any ideas on how to get Excel to make the plug-ins active?
Thanks ... bill burrows
Hi !!
I read that it is possible to create a custom algorithm and use it as a plug in to sql server 2005. What programming language are available for this purpose ? C++ only ? Can I use .net ?
Thank you!
Hello,
for an internship i am writing a data mining plug-in algorithm in SSAS in C#. My algorithm is a subgroup discovery algorithm and for determining the quality of the the discoverd rules/ patterns, i need to know what the support is of the rules.
The rules are of the form (a = x AND b < y THEN c = z). I managed to obtain some statistics by calling MarginalStatistics.getCasesCount(..,..). But I would like more functionality.
For example the data mining structure:
id | column1 | column2 | column3 | column4
1 1 1 1.0 1
2 1 2 2.3 1
3 1 2 1.1 2
I want to evaluate the rule (column1 = 1 AND column2 = 2 THEN column3 > 0). The result should be 2. Now is my question, how do i get the support of my rule in my in C# written algorithm?
Thanks in advance,

Hello,
I need to develop a Probit Regression Plug-In Algorithm.
Does anyone know if the plug-in framework will reasonably handle a Probit Regression?
Is anyone aware of any code or materials, specific to a Probit Regression Plug-in, that would help me to do this?
I am also interested in applying the dprobit methodology found in Stata for infinitesimal changes in independent variables.
Has anyone been successful using Stata to implement an SSAS plug-in algorithm?
thank you,

Hi,
In SQL Express SP2, when I select Tools > Options, there is a place where I am supposed to be able to specify the source control plug-in. I have SourceSafe 2005 installed on this machine, so I see these choices in the drop-down:
None
Microsoft Visual SourceSafe
Microsoft Visual SourceSafe (Internet)
The problem is that whenever I select one of the SourceSafe options, it goes back to "None".
I'm not even sure how the source control intergration works, but I figured I have to select the plug-in before doing anything else.
How can I select the SourceSafe plug-in under SQL Express SP2?
Thanks,
Mark
Hi, all here,
I am having a question about plug-in algorithms in SQL Server 2005. Since we are able to implement our own algorithms in SQL Server 2005 analysis services architecture, so my question is: what benefits can to a great extent be achieved? Like say, we are going to implement a plug-in algorithm, so what considerations should be concerned?
Thanks a lot in advance for any guidance and help.
Hi, anybody help me how to develop Today Screen plug in for WM5 pocket pc.
View 1 Replies View RelatedHi, all here,
I am having a more considertaion about Data Mining plug-in algorithms. When we say we are going to embed a uesr plug-in algorithm, so what is the context for that ? I mean in which case then we thing we need to embed a user plug-in algortihm? I know when we say we are going to embed a user costomermized plug-in algorithm, it means we want something more costomized. But what kind of customized features are generally concerned? Is it independant for different market sectors?
I dont think we can just try to embed a plug-in algorithm then compete it with avaialble algorithms to see which one is with better prediction accuracy?
Would please someone here give me some guidances about that?
Hi,all here,
Could please anyone here help me for this problem?
My problem is: I have registered my plug-in algortihm with SQL Server 2005 analysis services, and I can see my plug-in algortihm added to the analysis service configuration file (msmdsrv.ini). But why I can not see my algorithm appearing in the list of algorithms when I tested it? Really need help for that.
Thanks a lot for any guidance and help.
With best regards,
Yours sincerely,
Hi,
actually i want to implement a c# component that can help third party data mining algorithm
and i want managed plug-in algorithm (without wrapper),.
is it possible to write whole application in c#
as Analysis servisce is in c++ , can we implement it in c#
thanks in advance

I got an Assertion failed error while resizing a vector in a plug-in algorithm.
In order to isolate the problem I created a simple model class in Navigator.h file as shown below:
//========================= begin code =======================
class CStateStats
{
public:
DOUBLE m_dblSum;
DOUBLE m_dblSqrSum;
public:
CStateStats()
{
m_dblSum = 0.0;
m_dblSqrSum = 0.0;
}
};
class CAttStats : public DMHALLOC
{
public:
dmh_vector<CStateStats> vstatestats;
public:
CAttStats() : vstatestats (*this)
{
}
};
//========================= end code =======================
The access to DMHALLOC is provided in that class and in Navigator class as shown below:
//========================= begin code =======================
class ATL_NO_VTABLE NAVIGATOR :
public DMHALLOC,
public CComObjectRootEx<CComMultiThreadModel>,
public CComCoClass<NAVIGATOR, &CLSID_NAVIGATOR>,
public ISupportErrorInfo,
public IDMAlgorithmNavigation
{
public:
NAVIGATOR() : _viAttributeOutput(*this), _vCAttStats(*this)
//========================= end code =======================
I succeded making room for _vCAttStats vector, but when I tried providing room for the vectors of the vector I got an Assertion failed error (file dmhallocator.h Line:56 Expression assert(_dmhalloc._spidmmemoryallocator != NULL)). Please, see the code below, included in NAVIGATOR::GetNodeArrayProperty function:
//========================= begin code =======================
_vCAttStats.resize (2); // <<<<< succeeded here!
// make space for the states
_vCAttStats[0].vstatestats.resize(ulStates); // <<<<<<< assertion failed here!
//========================= end code =======================
I tried using a vector-of-vector approach and I also succeeded.
But I have to use that kind of structure: a vector of class with a vector inside.
I think I must provide a similar approach of vector-of-vector existing in DmhVector.h but I don't know how to do it.
I would apreciate any help.
managed plug-in framework that's available for download here: http://www.microsoft.com/downloads/details.aspx?familyid=DF0BA5AA-B4BD-4705-AA0A-B477BA72A9CB&displaylang=en#DMAPI.
This package includes the source code for a sample plug-in algorithm written in C#.
in this source code all .cs files are modified for clustering algorithm
if my plugin algorithm is of association or classification type then what modifications are requried in source code???
