Where Can I Store The Mining Results From Mining Models In SQL Server 2005 Data Mining Engine?
Apr 26, 2006Hi, 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.
Data Mining :: Informational (Data Mining) - Decision Trees Found No Splits For Model
Sep 29, 2015I 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.
How Can We Compare Other Data Mining Software Packages With SQL Server 2005 Data Mining?
Feb 23, 2007Hi, 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,
Data Mining - Scalar Mining Structure Column Data Type Error...
May 31, 2006Hoping 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?
Data Mining :: Content In Data Mining Structure Not Valid - Deployment Fails
Apr 30, 2015I'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?
Data Mining :: MS Excel Data Mining Add-ins / Maximum Number Of Predict Columns
Jun 4, 2015Having 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.
Error (Data Mining): The 'HISTORIC_MODEL_GAP' Data Mining Parameter Is Not Valid
Oct 25, 2007Hi 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.
Data Mining :: Implementing Excel Data Mining In A Classroom Setting?
Jun 15, 2015Implementing 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?
Data Mining Query Returns ADOMDDataReader
May 22, 2006Hello,
I created a Market Basket Data Mining Model with Association Rules, which I want to query and show in a Report. Everything works fine, when I preview the result in the Reporting Services Data tab I see some sort of table which I can expand and then see the related products.
Unfortunately this result seems to be an ADOMD Datareader which I cannot place in a table, matrix or textfield.
If anyone knows how I can make this Informationen available in my Report please let me know.
Thanks in advance

View 2 Replies View RelatedHow Is The 'Score' Value Derived In The Lift Chart/Mining Legend For Data Mining Models?
Sep 26, 2006Hi,
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
Excel 2007 Data Mining Add-in Advance Create Mining Model Question
Apr 11, 2007Hi,
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?
Data Mining Query Task And Connection Problems
Jan 10, 2008Hi!
I have problem using Data mining query task: when I want to set connection to Analysis services DB I don't see connections created in connection manager (they are not listed in the dropdown). (I can click on "New" and create new one but I already have one created in connection manager.)
Also, I want to make connections created in the connection manager flexible, easy to change after transfering package(s) to another server. How to do that?
Thanks in advance!
Web Based Data Mining Query... Installation Issue..
Dec 4, 2006Hey gang,
I have ran into an installation issue that has been bugging me all weekend. I'm trying to run the preditive analytics query from a web based application (ASP.NET). I have installed a data pump as directed by this article "Configuring HTTP Access to SQL Server 2005 Analysis Services on Microsoft Windows Server 2003" because this isn't set up under a domain. I also set appropriate roles in Data Mining Database (set it to everyone for testing purpose).
ConnectionString is "MSOLAP.3;Persist Security Info=True;Data Source=http://1.0.0.1/olap/msmdpump.dll;Initial Catalog=DataMiningDB"
Try
Dim connection As AdomdConnection = Me.Connect
Dim command As New AdomdCommand(txtQuery, connection)
Dim adapter As New AdomdDataAdapter(command)
Dim dataset As New DataSet
' Fill the dataset
adapter.Fill(dataset)
' Bind to grid
Return dataset
Catch ex As Exception
Throw ex
End Try
Return Nothing
Exception Details: Microsoft.AnalysisServices.AdomdClient.AdomdErrorResponseException: Errors in the high-level relational engine. A connection could not be made to the data source specified in the query.
Errors in the high-level relational engine. A connection could not be made to the data source specified in the query.
OLE DB error: OLE DB or ODBC error: Login failed for user 'VMSQL2006IUSR_VMSQL2006'.; 28000.
It happens on the adapter.Fill(dataset). Any ideas?
I have also tried to set the olap application pool to use different identity instead of "Network Services", but I always get the same error message (but with user I specified instead of I_USR).

Error Message: Data Mining Query Builder Cannot....
Mar 12, 2007Hello,
I wrote a data mining plug-in algorithm in SSAS and now I am trying to view the lift chart in Management Studio. The studio gives the following error:
"The Data Mining Query builder control cannot be initialized due to the following problem:
Deserialization failed: Multiple definition of element 'Column12' causes the content model to become ambigious. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence."
I really do not understand what i did wrong. Can anybody help me?
Thanks, Joris
Can I Filter The Data On Mining Structure, Mining Model?
Jul 18, 2006I 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.

Executing An SSIS Package Containing A Data Mining Query Task From A SQL Job
Mar 28, 2007Hi, I'm new to this forum, so please bare with me.
I've created a mining model, i've tweaked it etc and i'm now happy with the results its producing. I'm now looking to automate the processing and exporting of the results of the model i've done this simply by creating an SSIS package with two tasks, one task being to process the model the other task is a Data Mining Query task.
This package works fine in visual studio and when i deploy it to the server.
The problem i'm having is when i then try to execute the package from a job, after a bit of investigating i have tracked it down to the Encryption of "sensitive" properties. By default the encryption is based on UserKey which is why the package works for me when i execute it from VS or even the server, but when the job trys to execute the package running under the sql agent account it fails.
Looking at the security options i have for packages, i can either DontSaveSensitive, EncryptSensitiveWithUserKey or EncryptSensitiveWithPassword plus a few others.
DontSaveSenstive is clearly not an option as this just creates an unusable package.
EncrptSensitiveWithUserKey doesn't seem to be an option as the job runs under the SQL Agent account (also i'm thinking that the UserKey that the encryption is based on also incorporates other factors related to my profile that i can't impersonate? i might be wrong though)
EncryptSensitveWithPassword seems to be an option except that i can't get this to work either, there doesn't seem to be anyware in the job step to give it the password information.
Its frustrating me now because i've fallen at the very last hurdle, if anyone else has experienced this problem and knows how to resolve it that would great.
Thanks
Bob.
Excel Data Mining Add-In Query Wizard Error Message
May 1, 2007Hello Experts,
I have an error message I was wondering if anyone else has seen and resolved. When I open excel and click on the query wizard on the Data Mining Ribbon, I get an error message that says "Input String not in Correct Format"
After I close this dialog box the 'Welcome to Query .... ' wizard will open, but when I select the Advance button my process aborts due to the input string error.
I have only ran association models on the computer.
The Manage Models and Browse buttons work fine.
The error came up on Friday, but it wasn't there on Thursday. There were no changes done to the machine (no installation of new software).
I have tried reinstalling the add-in.
Thank you all for your help,
Davy
I have pasted the SQL syntax below that I get from the error dialog box after the query wizard closes.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Sampling Data Set Via Integration Services Data Flow For Data Mining Models Without Saving Training And Test Data Set?
Nov 24, 2006Hi, 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.
With best regards,

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.
With best regards,

How To Access The Data From A Custom Data Mining Plugin ?
Dec 20, 2006I'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.
Data Mining :: How To Mine Data From One Spreadsheet And Place It In Another
Jun 15, 2015I 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?
Mining Query Builder
Jun 19, 2006On pages 123, 124 of Data Mining with SQL Server 2005, I can't finish the example. When I add 'Monthly' to the end of the expression "[Home Owners].[Theater Freq]" in the Criteria/Argument column, I usually get an error message saying the syntax is incorrect when I switch to the Results view. If I place a dot after the original expression, like this: [Home Owners].[Theater Freq].Monthly, I get an error message that "The dot expression is not allowed in the context at line 4, column 23. Use sub-SELECT instead." What am I doing wrong?
Thanks!
Excel Data Mining Add-in For Categorical Data
Jul 24, 2007Hi 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.

Excel Data Mining Add-in For Categorical Data
Aug 5, 2007Thank 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.

Create Mining Structure And Mining Model With Code
Oct 18, 2006Dear friends,
I encounter a serious problem.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Please help me.

Create Mining Structure And Mining Model With Code
Oct 20, 2006
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.

Mining Structure Has To Contain At Least 2 Mining Models To See Their Accuracy Charts?
Nov 27, 2006Hi ,all here,
Thank you very much for your kind attention.
I just found that I am not able to view the accuracy chart for my mining model. The error message is: no mining models are selected for comparision. Which is quite strange.
Any guidance? thank you very much.
With best regards,
Yours sincerely,
