hi,
as we know we get clustering algorithm with managed plugin algorithm API
does anyone have developed any other plugin algorithm as i want to check what are the things that needs to be modified. i am not data mining algorithm developer but i just want to check where we have to make changes. i would be better if i get source code for algorithm other than clustering
ANOTHER PLUGIN ALGORITHM REQURIED??
thanks in advanced
I have a code for Nearest neighbour algorithm, I want to build a datamining algorithm using that code..
I have the following link that includes the source code for a sample plug-in algorithm written in C#.
(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.
But i am confused on where to insert my algorithm logic?
Hey, all...Some time ago, I used a tool which I believe was available from Sun. Itwas a java applet, as I recall, which sat between a SQL client and aSQL server. It allowed the client to connect to it at any port, andwould in turn connect to the server at the standard TCP port (orwhatever the server was listening on).It logged all SQL traffic between the two nodes to a flat file.Has anyone ever heard of this tool? For the life of me I can't rememberwhat it was called.Thanks!BD
View 2 Replies View RelatedI've developed a web application and to be honest I've been a bit dumb and not checked with my hosts. I assumed they used SQL Server 2005. But no, they only use 2000.
I'm sure I'll come across more problems but the first I'm having is I've used the ROW_NUMBER() function in a few stored procedures, but in 2000 I'm getting this error message
'ROW_NUMBER' is not a recognized function name.
Here is the stored procedure for reference
SELECT RowNum
FROM
(
SELECT id, category, ROW_NUMBER() OVER(ORDER BY id) as RowNum FROM custrecords
)
as CustRecord
Good morning everybody,
I'm here once again asking for help. Here's my problem:
I have a table that I use in my text mining clustering third-party algorithm. The table is as follows:
ID: primary key (int)
ID_DOC: an ID I use to know from what document a term came from (int)
ID_TERMO: the term ID (int)
TERMO: the term itself (varchar(max))
FREQ: the term frequency, usually TFxIDF (real)
Alright... I need the term itself to do some visualization. What I want to do is to get each case's term and store'em on a vector<char*>. So I did some changes on the ProcessCase method. In this method the data (each variable of the case) can be accessed rolling over the case using a DM_STATE_VALUE* as follows:
DM_STATE_VALUE* xpto = (DM_STATE_VALUE*) rgValue;
for(unsigned int i=0;i<_cAttribute;i++) { // _cAttribute is the number of variables
double aux = xpto.r8;
//Do some calculation using aux
}
Alright... It works quite well when I only have real and int data types on the database. But how the get the term collumn (varchar(max)) ?
How to modify the DM_STATE_VALUE union to accept strings as well ?
Any clues are wellcome.
Thanks a lot once more,

Hi,
I want to create a Data Mining Plugin-Algorithmn that uses existing mining models in the current DB. Is there a way to get a AdomdConnection from within an (Managed) Plugin-Algorithmn? This Connection should point to the current SSAS-Database.

Manfred
Hi,
I spent the last days programming a managed datamining plugin-algorithmn for SSAS 2005 and have troubles with the Prediction-Method.
Die Prediction-Methode of the "Shell-Algorithm" leads to an error-message on execution of the prediction-query (Internal Error: Unexprected Error ... dmxpredict.cpp Row 205 ...).
Can anyone provide me with a very simple implementation of this Method which just says that for every output-attribute the first (discrete) state should be predicted with a probability of, let's say, 90 % ?
Best Whishes

Good evening everyone,
I'm following the steps of the tutorial on how to construct a managed data mining plugin in C#.
Once created the Metadata, Algorithm and Navigator classes I tried to register it on Analisys Service by running the XMLA template written on the tutorial but I got the following error:
Unable to retrieve a list of supported data mining algorithms. Make
sure you are connected to the correct Analysis Services server
instance and the Analysis Services server named localhost is running
and configured properly. You can continue with a default list of data
mining algorithms
The GUID in the XMLA is correct as so the service name. The SQL Server engine runs fine.
I noticed that when I run this XMLA, the file msmdsrv.ini is modified, so in DataMining/Algorithms session a new entry is correctly created, enabled and the GUID is also set correct.
I also tried to ignore the XMLA setting up msmdsrv.ini manually but it also didn't work.
The build process is fine, both DMPluginWrapper and the Shell are registered by gacutil and I restarted (also try to stop and start) the server.
Any ideas will be very appreciated.
Thanks,
-Renan
Good afternoon,
I've developed a clustering plugin for SQL Server 2005 but now I want to port the .dll so my algorithm can run on another machine. Both machines have SQL Server 2005 installed, but different versions of Windows.
What are the steps I need to follow to port the plugin ?
Any help will be very appreciated.
Thanks a lot once more,

Hi,
After I've written my first Plugin-Algorithmn, I have some general questions about the Managed Plugin-Algorithmn wrapper.
What does the Property "support" express in view of predictions? Is it the overall number of cases the found rule works for?
What's the difference between AdjustedProbability and Probability ?
There is a probability for a specific StateStatistic and one for the whole AttributeStatistic.
What does the latter one express? Perhaps the overall probability that the discovered rules will lead to correct results for this attribute ? Let's say I have two rules for an attribute. Rule A has a probability of 0.5 and Rule B has a probability of 0.66. What would be AdjustedProbability.Probability in the case? The mean of 0.5 and 0.66 ?

hello,everyone,I also met a problem.
I stoped the SQL Server Analysis Services first, and registered the GAC successfully,
then modified the msmdsrv.ini manually.In fact,I found the format of my msmdsrv.ini is diffirent from the one mentioned in the tutorial,it just like below:

when i restarted the the AS,
some error information displayed in event viewer,
" can't load MyCompany_Mamaged_Plugin_Algorithm data mining Algorithm provider(ProgID,

I am confused by it and have not any idea to solve it.
some one can give tips?

Community:
Suposse that some models are deployed in Report Server for a while, and users have developed some ad-hoc reports on them using Report Builder, (some of the models are SSAS Cubes).
Modifications are required for a Model, what is the procedure to deploy this modifications? What happens with ad-hoc reports of this Model? Rewrite all the reports is a VERY BAD option, I agree that some reports must be rewrote, but only if they reference objects no longer valids in new model.
I suposse that the procedure for SSAS Cube Models will be different for a Relational Database Source because metods of generating models are so different. (I am particularly curious about Cubes, I can't figure out how I can do it)
Suggestions and links will be very appreciate.

We have a large number of SPs in our databases and decided it was time to get some source control. I have VSTS team explorer installed and working in visual studio, but I cannot get the plugin for SSMS to work - it just says none in the current source control plug-in dialogue box - nothing when I drop it down either.
Any ideas what I am doing wrong?
Good afternoon,
I'm doing a custom clustering plugin for text to pre-process ("clean" the texts), calculate weights, estimate the number of clusters (using the PBM index) and finally, do the actual clustering.
So... I've made each of these modules on C++ and I'm putting them all togheter on the plugin.
My database (MDB file) has only one table, with only two fields within: a key (auto-incremental) and a small text. What I intend to do is to get the text in each test case, store them togheter somewhere and call my classes to cluster these texts.
I'm trying to log the texts in a file (just a test) on the ProcessCase method, in the CaseProcessor class. I've did it with no problems with numerical data.
But when I load the MDB file on the Mining Structures Wizard, it says the content type of the field holding the texts is "Continous" and the data type is "Text". Actually, when I saw it I didn't really mind.
But when I run the mining model it gives me the following error: "Error 1 Error (Data mining): The data type of the Table1.Texto mining structure column must be numeric since it has a continuous content type (Content is set to Continuous or Key Time or Key Sequence). 0 0 "
So... How do I change this content type ? (the content type combobox on the Mining Structures Wizard couldn't the changed)
Can anyone help me on this, please ?
Thanks a lot.
Good morning,
Well... As I said in other topics, I'm doing a clustering plugin for text mining. I'm facing many problems and, with your help, solving them one by one.
First of all, thanks a lot again.
Well... I've made a clustering function that is actually working very well. But I'm exporting its results to a log file I use as an algorithm trace for debugging.
My clustering method returns a vector containing information of what cluster each register belongs. For instance:
vector[0] = 1 -> The register of index 0 belongs to cluster 1.
vector[1] = 9 -> The register of index 1 belongs to cluster 9.
vector[2] = 2 -> The register of index 2 belongs to cluster 2.
...
And so on.
But... I know that none of the Navigation methods receives a structure like this one discribed above. I only use it to log the results to debug the algorithm.
But how to pass this information (what register (or test case) belongs to what cluster) to the Navigation ?
Thanks a lot again, and any help will be very appreciated.

View 4 Replies View RelatedI'm stucked in a problem and I thought if you would be so kind as to helping me to resolve it.
I'm implementing a clustering algorithm plugin for text mining. I've already read the tutorials and sample codes provided by the MSDN Library.
Well... My problem is: I can't go through the data when the Predict method is called. I've read that this method implements the "core" of the custom algorithms. Here is a small snippet of my code for you to understand my doubt:
STDMETHODIMP ALGORITHM::Predict(/* [in] */ IDMContextServices* in_pContext,/* [in] */ DM_PREDICTION_FLAGS in_Flags,/* [in] */ IDMAttributeGroup* in_pPredAttGroup,/* [in] */ DM_CaseID in_CaseID, /* [in] */ ULONG in_ulCaseValues,/* [in] */ DM_ATTRIBUTE_VALUE* in_rgValues,/* [in] */ ULONG in_ulMaxPredictions,/* [in] */ ULONG in_ulMaxStates, /* [out] */ DM_ATTRIBUTE_STAT** io_prgPredictions,/* [out] */ ULONG* out_pulPredictions) {
for(UINT i=0;i<in_ulCaseValues;i++) {
DM_ATTRIBUTE_VALUE& dmattributevalue = in_rgValues;
ULONG iAttribute = dmattributevalue.Attribute;
if (iAttribute == DM_UNSPECIFIED)
continue;
double dblValue = ::DblContinuous(dmattributevalue.Value);
char buffer[129];
sprintf(buffer,"%f ",dblValue);
RENAN_Log::log(buffer);
}
return S_OK;
}
As you can see, I'm going through in_rgValues to get its values, but i'm only obtaining the first register of the table on the database. I need to roll over a kind of resultset so I could access all the registers I need. Is there any way to do so ?
I expected Predict() received a matrix containing all my data, but the only thing I noticed that could represent the data is that in_rgValues vector. So I can go through this vector, but it holds only the first register of the table in the database (that's what's being saved on my log). I need all of the registers in order to pre-process the data and implement my clustering algorithm.
Well... That's it... I would be very pleased if you could help me.
Does any have a algorithm that can divide A into B without using the divide
sign (/) or the multiplication sign ( * ).
I am new to DM and I am not sure which algorithm would be best to use.
I am trying to build a custom comparitor application that companies can use to compare themselves against other companies based on certain pieces of information. I need to group a company with 11 other companies based on 6 attributes. I need the ability to apply weightings to each of the 6 attributes and have those taken into consideration when determining which 10 other companies each company is grouped with. Each group must contain 11 members, the company for the user logged in and 10 other companies that it will be compared against.
At first I thought that clustering would be a good fit for this but I can not see a way to mandate that each cluster contain exactly 11 members, I cannot see a way to weight the inputs, and I think each company can only be in one cluster at a time which do not meet my requirements.
Any help will be greatly appreciated!

Hello,Do you know if the algorithm for the BINARY_CHECKSUM function in documentedsomewhere?I would like to use it to avoid returning some string fields from theserver.By returning only the checksum I could lookup the string in a hashtable andI think this could make the code more efficient on slow connections.Thanks in advanced and kind regards,Orly Junior
View 3 Replies View RelatedWhat kind of algorithm does the MAX command uses? I have a table that I need to get the last value of the Transaction ID and increment it by 1, so I can use it as the next TransID everytime I insert a new record into the table. I use the MAX command to obtain the last TransID in the table in this process. However, someone suggested that there is a problem with this, since if there are multiple users trying to insert a record into the same table, and processing is slow, they might essentially come up with the same next TransID. He came up with the idea of having a separate table that contains only the TransID and using this table to determine the next TransID. Will this really make a difference as far as processing speed is concerned or using a MAX command on the same table to come up with the next TransID enough? Do you have a better suggestion?
Thanks
