What Is The Environment For Data Mining Programmability?
Jun 5, 2006
Hi, all here, I am new to data mining programmability. And as we know with the data mining programmability, we can integrate data mining with client applications via a series of data mining programmability APIs like AMO.NET, ADOMD.NET,SERVER ADOMD.NET, OLEDB, ADO,ADO.NET and so on. So what is the environment for the data mining programmability then? I mean what kind of IDE can we develop the data mining programmabiliy? Thanks a lot for any guidance and help.
With best regards,

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.

I followed the tutorial posted at [URL] ...
Everything was ok until the last step where I had to process the mining structure which resulted in a warning
"Informational (Data mining): Decision Trees found no splits for model, Tbl Decision Tree Example."
What does this error mean? How do I resolve it? Also, I only see the first level in the Mining Model Viewer, I don't see the levels 2 and 3.

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.
With best regards,
Yours sincerely,

Hoping someone will have a solution for this error
Errors in the metadata manager. The data type of the '~CaseDetail ~MG-Fact Voic~6' measure must be the same as its source data type. This is because the aggregate function is not set to count or distinct count.
Is the problem due to the data type of the column used in the mining structure is Long, and the underlying field in the cube has a type of BigInt,or am I barking up the wrong tree?

I'm a beginner with SQL 2012 SSDT & SSMS. I get this error message when I try to deploy my project:Â
"Error 6
Error (Data mining): KEY SEQUENCE columns are not supported at the case level. The 'Customer Key' column of the 'TK448 Ch09 Cube Clustering' mining structure contains content that is not valid.
0 0
"
I am finding it hard to locate the content that is not valid. I've been trying to find a answer for this problem but can't seem to find anything. How can I locate the content that is not valid and change or delete it so that I can deploy this solution?

Having successfully created :
- a data mining structure with about 80 columns.
- a data mining model using Microsoft_Decision_Trees with 2 prediction columns.Â
I thought I would then explore the possibility of have more than 2 prediction columns, in this case 20.
I get an error message and I can't work out :
a) if this is because there's a limit to the maximum number of prediction columns and where that maximum is stated.
b) if something else has become corrupted
c) there's a know bug and if the error message is either meaningful or not.
Either way, I'm unable to complete the data mining wizardÂ
The error message is :Errors in the metadata manager. Either the mining structure with the ID of '[my model Structure]' does not exist in the database with the ID of 'DMAddinsDB', or the user does not have permissions to access the object.

Hi all,
I am using Microsoft_Time_Series and have set HISTORIC_MODEL_GAP to various values (from 1 to 21). I always get this error:
Error (Data mining): The 'HISTORIC_MODEL_GAP' data mining parameter is not valid for the 'My Time Series' model.
In Algorithm Parameters window, this parameters is not there by default, so I have to add it.
Any tip will be greatly appreciated.

Implementing data mining Add-in in an academic setting? We need to handle over 150 new students a semester and have their connection to Analysis Services survive for their four years at the college. We are introducing data mining to every freshman business student as a unit within their Intro to Excel class (close to a month of work to give them a sense of what is possible). Other courses later in their curriculum will expand on that introduction.Â
Once implemented, we would have as many as 900 connections to manage (four years from now). It is possible that multiple sections will be running at the same time, so 40 students may be accessing the data mining tools concurrently. Â
Is there a way to "bulk establish" the access credentials and establish those databases?

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,
S Rajput

Hi,
I am trying to model data in analysis services with the Advance Create Mining Model function in the excel addin. I am having trouble creating an association model that works like the Associate button above the Advanced button.
The format of my data is like this
OrderID Product
100 Bike
100 Helmet
100 Shoes
200 Helmet
200 basketball
200 Bat
300 Shoes
300 Socks
The associate button works perfectly since it asks me which column is the transaction id (orderid) and which column I am trying to predict (product). The advanced create mining model asks me to determine what the columns are...
OrderID=key Product=Input+Predict?
When I run the advance create mining model associate, I get a browser that gives me no rules and the support for only one item itemset (each product but no combination of products).
Does anyone know what I have to do to get it to work like the associate button?

I perform data mining on all products and a specific product category.
Do I need to create 2 data source views, one for all products and the other one for the specific product category?
Afterward, I run the Data Mining Wizard 2 times to create 2 mining structures.
I also need to add the same mining model (e.g. Bayes, Cluster) to each of these mining structures.
Is there any simple way to do it?
Thanks.
Joe.

Hello there
I have several developers working on different systems but same database; these developers make Store Procedures and all utilize these SP€™s; at the moment our SP list grows and keeps about 200 + SP's, whereas I expect a lot more to come.
Now I want to organize the SP''s under certain folders; example by the System and underneath by User name so that traceability of the work can be easy as well as organization of the SP's will be achieved.
I cannot find any way how to customize the Store Procedure node; and create folder underneath.
I know the filter option helps for searching the SP's but we also have remote users who are working somewhere away from us; so I want to get their work only by filtering the folder of these user name and also sometimes I need to know who made these SP's so that that developer can fix or alter the procedures.
We may do this using security instead of dbo, the developer who is creating the procedure will carry his name; but this needs tight security and we are in the phase of testing and lot of changes occurs on daily basis which requires little loose security till we pass this phase.
Any Idea or suggestions to make it viewable and accessible and copy the work of the specific users right away; rather than searching his Sp's, with the coordination of the user or with the maintained documentation.

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.

Hi, all experts here,
I am wondering is there any way to select only a portion of a data set to train the mining model? In this case, I mean we dont need to split the dataset in advance, what I want to do is being able to select any random portion of a selected dataset to train a mining model. Any advices?
I am looking forward to hearing from you and thanks a lot in advance for your advices and help.

I'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.

I have very little experience with programming and data mining, but I am working on a project where I need to take data from one spreadsheet and place it in another. Since it is hard to describe what I would like to do, I will provide an example:
SPREADSHEET 1
Column 1, Column 2
100, ?
101, ?
102, ?
103, ?
SPREADSHEET 2
Column 1, Column 2
102, 202
100, 200
103, 203
101, 201
In this example, the data in Column 1 is always tied to the data in Column 2 (i.e., 100 in Column 1 means 200 in Column 2, etc.) However, the data for Column 2 is only available in SPREADSHEET 2; moreover, the data is not in the same order in both spreadsheets.
My question is how can I create some sort of program where I can transfer the data from SPREADSHEET 2 into SPREADSHEET 1?

Hi my friends,
I do have a problem with results of clustering algorithm with my categorical data.
In reality I have a big table with one's and zero's and I try to cluster according to 60 attributes.
I tries to cluster to two categories many times but I get only one cluster. What do you suggest. Which values can I change to the algorithm? Is there anything particular for categorical data ?
Thank for your help in advance.

Thank you very much for your previous answers conserning clustering algorithm.
I change a bit my data and now I can get two and three clusters as I wish.
But now I have a different question. I wish to keep my Structure and Model for further trials with different algorithm values, like cardinality. I tried the following
I selected in excel Data Mining and then the option cluster button.
Then in the cluster wizard I chose analysis service data source and I reform the query as I need adding only at the end
where "STAFF_YES" = 1. Then I choose the needed columns and target value. Finally I select browse model, enable drill through only and I finish the wizard and get some results, rather good. But i need to try again with different parameters.
I tried Business intelligent Studio to check my Analysis service. The structure were here but when I changed any parameter and I tried to reprocess I got the following messages
Processing Mining Structure 'try Structure_1' completed successfully.

Thank you very much for your help.
The errors that I can see in the code that you gave in your answer are the following and they are more or less the same as I had previously
I tried the code but initially I have encounter the following problems.
1. In any line that have the declaration As Server, As Database like in
Public Function CreateDatabase(ByVal srv As Server, ByVal databaseName As String) As Database gives me the problem that type Database is not declared the same type Server is not declared and it does not give me any option.
2. In addition to that for As DataSource, As RelationalDataSource, As RelationalDataSourceView, As ScalarMiningStructureColumn, As DataSourceViewBinding, gives me the problem that type is not declared.
3. Finally in mc = New MiningModelColumn("Yearly income", Utils.GetSyntacticallyValidID("Yearly income", Type.GetType(MiningModelColumn))) is not accesible in this context because it is 'Private'.
I have some more problems but I thing that by solving the above that I referred I will solve the rest.
Thank you any way.

Hi,
I've come along way learning about databases and SQL. I can write basic queries now. Even some with subQueries. What I need to learn, is how to approach data mining. Can someone suggest the best path to follow, to learn how to accomplish data mining from a very large database?
I don't just need to produce reports of acquired data. I need to go in and grab data and look for patterns against known result sets. I hope that makes sense.
Thanks,

Hello all,
I was handed a new project and I'm not quite sure how to do it or even what technology to use. Now, I think that SQL Server's Analysis Services could help (or even do the entire thing) but I'm not sure. So, basically, I'm looking for recommendations and ressources on the subject.
Here's my scenario:
We have a Data-Warehouse that stores information about the production of our company. Around this fact table, we have multiple dimensions including one about the origin of the production (who) and a time dimension (when).
We are buiding cubes and linking Excel to them for future analysis. Everything is done. Now, the all-mighty supervisors would like to have some predictions built-in to the system for the rest of the year based on the previous years. Basically, we would be adding production values for every possible time (the step is every hour, so the sum of the production comming from a certain origin is set as the fact and linked to a time dimension row for that hour).
As you can see, it's not very difficult and it seems to me like Analysis Services might already have that functionnality although I couldn't find it (seems like predictions can only be made by looking at relations found by the data mining algorithms and these predictions need to be made by a human because they are not really registered as "new" facts).
So, in short, I'd like to have a tool calculate future productions for the rest of the year and set a new column (or dimension) to a certain value indicating that this fact row has been predicted and is not certain. Of course, the refreshing of data would not create duplicate rows for predictions, newer predictions (probably based on more facts) would replace the last equivalent prediction.
I hope that's clear.
What do you recommend I use? Is it a case where I will need to build my own separate program (that updates the data-warehouse) or is it possible to achieve this using data mining?
Thanks a lot,
Skip.
