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

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!

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,I am studying data mining features of SSAS and for a workshop I'vecreated 2 views derived from vTargetMail view of AdventureWorksDW.Train data consists every record except those in Pacific, and testview consists only records from Pacific area.1. I've created a mining structure based on Decision Tree and selectedBikeBuyer as predictable column.2. According to input column suggestions, I've selected Age,Eng.Education, NumberCarsOwned, YearlyIncome, CommuteDistance,NumberChildsatHome and TotalChildren as input columns,3. I've modified no other setting, and deployed project.I can get training results in decision tree browser and dependencynetwork (and both seem to give rather logical results) however, when Itry to browse lift chart or classification matrix I get an emptyclass.matr. and a lift chart of a single 45 degree line.Am I missing a step, or must I do some fine-tuning on (what)parameters?Thanks...

Hi, 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,
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.

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

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,
Bill Littlewood

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.

Hi, all experts here,
I would like to know if there is any way to migrate third-party data mining packages with SQL Server 2005 data mining algorithms together then we can have a comparison among all of them to get the best results for training models.
I am looking forward to hearing from you.
Thanks a lot.

I need to create a set of cases for a project that uses the Microsoft Association Rules algorithm to make recommendations for products to customers. My question is: the set of scenarios must include all transactions of customers for training?. or is it sufficient some percentage of total transactions? If i do not use all transactions of customers, could be that the algorithm does not consider some products in their groups or rules and could not make recommendations about these?
thanx

MS uses the a priori algorithm in Association Rules, while other DM software have gone to the Novel Algorithm. Can you tell us why MS decided to stay with the a priori? Did you overcome the limitations that it's accused of having? Thanks!

In assotiation rules each rule has a [support, confidence] part. In Microsoft Association Rules there is a [probability,importance] measure in each rule and importance can be greater that 1.
I found the following in msdn but i'm not sure if i understood correctly.
MINIMUM_PROBABILITY: Specifies the minimum probability that a rule is true. For example, setting this value to 0.5 specifies that no rule with less than fifty percent probability is generated.
The default is 0.4.
MAXIMUM_SUPPORT: Specifies the maximum number of cases in which an itemset can have support. If this value is less than 1, the value represents a percentage of the total cases. Values greater than 1 represent the absolute number of cases that can contain the itemset.
The default is 1.
My questions are
1) Can i explain the [probability,importance] in [support,confidence]? If yes, how?
2) What importance>1 means?
Thank you in advance.

hi
i m trying to build microsoft association model using Microsoft association algorithm. i got
1) patient table(patientid, name, city)
2) diseases(diseaseid, dieseasename)
It is M:N [many to many] relationship between above tables, so
3)Patient_diseases(patientid,disease_id). [RELATIONSHIP TABLE]
i am trying to associate city in patient table --> disease in diseases table. I want to build association data mining model and use it on web form, such a way when the user enters city associated disease will be displayed.
should i select all 3 table to build the model? could help me to decide what tables should i select as Case and what tables as Nested? what attributes from the table should i select as key, input, predictive ?
i am using data mining tutorials on sqlserverdatamining.com to build this model. is there anything further during my model building i get into confusion? please suggest me where i can find complete resource or inform here.
i appreciate Mr.Jamie for his guidance so far in my academic project. i do have the book 'Data mining with sql server 2005'. I left with just one day to do this and document.
hoping someone could suggest. your help is much appreciated.

Hi
I am working on an academic medical project. I have created PATIENT table
PATIENT_ID
NAME |
CITY
DISEASE table
DISEASE_ID
NAME |
and Relationship table[FOREIGN KEYS]PATIENT_DISEASE
PATIENT_ID
DISEASE_ID
I am using Microsoft association algorithm [SQL Server 2005 BI Studio] to find association between PATIENT CITY --> Associated DISEASE. I will be entering dummy data into these tables as this is academic project. I like to know can i be able to find the associated Disease/s with the PATIENT City with this algorithm ? such a way as soon as the user enters PATIENT City, assocaited Disease will be selected from the diseases table? on web interface [asp.net].
i like to know after building this association model, can i use it on my web page to prompt the user associated disease with patient city? or building this model only gives association rules, i need to write a procedure or t-sql statements to implement the association rules?
I am using SQLSERVERDATAMINING.COM tutorials to build the model.
Your information and help is highly appreciated.

I'm looking for suggestions on the right design approach in relation to a problem that resembles Basket analysis. The data to be analyzed is a dimension Attribute_DIM and contains an ID, Attribute and Attribute_Value. Some examples of the data are :
ID Attribute Attribute_Value
1 Color Black
1 Movie Men in Black
1 Book Of Human Bondage
2 Color White
2 Movie Men in Black
2 Book Grapes of Wrath
We need to be able to analyze multiple selections of the dimension. For example,
Men In Black
Grapes Of Wrath Of Human Bondage
Men In Black Black 1 1
White 1 0
I have had some success using the Association Algorithm Mining Model. I think It is an overkill since I only need descriptive and no predictive analysis.
I'm looking for some ideas on the right approach to this problem. Ideally, we need to present the data in a cube and have the possibility to perform member analysis of the dimension.
I have looked at several articles (including http://msdn2.microsoft.com/en-us/library/aa902637(sql.80).aspx and http://www.aspnetpro.net/newsletterarticle/2004/10/asp200410ri_l/asp200410ri_l.asp). I'm not convinced those are the solutions and would appreciate any insight into this problem.
Thank you,
Anna.

Hi,
I've been playing around with the association mining model in SQL server 2005 and built a market-basket analysis of my data that I'm pretty happy with. The next task for me is figuring out how to run DMX queries against the data that I've just mined, so we may possibly use it in a web based application. This wouldn't necessarily be a difficult problem (and still may not be), but every example I've seen for the Mining Model Prediction Designer uses relational databases and I built my mining model off OLAP. Therefore, my predictable attribute is nested and when relating the mining model structure to the relational database that the cube was built off always gives me an error:
"Errors in the high-level relational engine. The 'CompanyName' column could not be found in the top-level clause of the SHAPE statement."
What I would like to do, and I'm not really even sure how I should structure any of my queries, is feed the model a product and have it return a listing of all the products it predicts. Currently, I've only been able to get the designer mode to process a singleton query, and even that didn't return any useful data. I know that this probably can be done pretty easily so any advice you may be able to offer would be greatly appreciated!!
So you may better understand my question, my association mining structure hierarchy looks as this..
[Model] ProductRecommend
[Case][Key]CustomerList
[Case][Attribute]CompanyName
[NestedTable]Product
[Nested][Key]PRODUCTCLASSID
[Nested][Attribute]PRODUCT
With that in mind, I'm trying to perform a query simliar to this:
SELECT
PredictProbability([ProductRecommend].[Product].[PRODUCTCLASSID]), <---- Throws Error for PredictProbability syntax no matter what I try to get to [PRODUCTCLASSID]
(SELECT [PRODUCT] FROM [ProductRecommend].[Product])
From
[ProductRecommend]
NATURAL PREDICTION JOIN
(SELECT 'test' AS [COMPANYNAME],
(SELECT '1234' AS [PRODUCTCLASSID],
'ProductA' AS [PRODUCT]) AS [Product]) AS t
Thanks again for any help!

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 all,
Is this book still the only book written for SQL2005's data mining? Does anyone know where I can find its errata? I have never seen so many editorial errors (typos, mislabeling, etc.) in other books. I am not worried about those obvious errors, but I am afraid that some errors may be so deceiving that when I find out, a lot of time will have been spent on misguided effort.

Hi
I am just starting to learn how to use data mining with SQL server 2005. I have some general questions which I hope someone out there can help me with.
Each month I have approx. 100.000 customers who buy a product.
I want to contact 10.000 of these with a letter for cross-selling some additional products.
Currently I choose these 10.000 randomly from the 100.000 customers. I now want to use SQL server 2005 data mining to choose these 10.000 better, to receive a better response rate. How do I transfer this knowledge to the 100.000 (potential cross-selling customers)
I understand that it could be set up in SQL server like the following:
case table: customer_id, gender, age, city, etc.
nested table: customer_id, product
Is this the way it should be approached and is there a special model/algorithm for this purpose?
Regards,
Dennis
