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 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

Please help me if you can Thank you in advnce Best regards. Manolis
- 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.
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?
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?
Is it at all possible to use this tool without any connection to SQL Server (mine data in Excel Worksheets only)?? Or is it required to connect to SQL Server?? From reading the documentation, one minute I get the feeling this is possible, then the next section I get a feeling it's not. Can anyone help? Thanks.
I managed to run a single DMX query from Excel using Data Mining Extension Add-in, however, I need to run DMX statements in a loop teaching my models from different data sets. Therefore I need to run multiple custom DMX statements (I thought Excel + VBA would be the easiest way to do that). How do I use Data Mining Extension Add-in from VBA level? I cannot find relevant documentation for that purpose anywhere.I use SQL Server 2012, MS Excel 2013 and I can easily run MDX and SQL queries from Excel, but somehow DMX won't work.
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.
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?
I install add-in and run fine for a while, then all of sudden I could not see Table Analyze tool and data mining tab at my ribbon. I re-run server configuration and re-connect to DMAddinDB (remote server, but I am the administrator), but data mining add-in and table analyzer still not showing at my ribbon.
Then I uninstall DMAddin, re-install it, go through configuration again, but still the tabs are not showing up.
I am trying insert the "Order by" clause into DMX but nothing is working.
INSERT INTO MINING STRUCTURE [ARS] ( [OrderID], [Product_Table](SKIP, [Product]) ) SHAPE { OPENQUERY ([dwMDA on PSD_TEST_TEST], 'Select Top 30000 "OrderID" From "dwMDA"."dbo"."vDetail" Order By "OrderID"') } APPEND ( { OPENQUERY ([dwMDA on PSD_TEST_TEST], 'Select Top 30000 "OrderID","Product" From "dwMDA"."dbo"."vDetail" Order By "OrderID"')} RELATE [OrderID] TO [OrderID] ) AS T
This is the DMX for market basket analysis.
I am also unable to use "order by" when i pull data into excel.
here's an example of something that doesn't work:
Select Top 20000 "OrderID","ProductGroupDescription" From "dwMDA"."dbo"."vDetail"
Order By "OrderID"
Can someone show me the exact working SQL commands they are using for the "Order By" clause when they import data from sql into an excel spreadsheet?
I encounter some promplems on using Data mining addins for excel, having to do with data mining staff. I have two questions.
1. In analyze tab, I try to use detect categories. I try to see in the help which algorithm do this and I see Naives, but when I check the mining model throught Microsoft visual studio I noticed that the algorithm is clustering. Is that the correct one? Does help have a mistake?
2. One more problem, I have to know some more thinks for the algorithm tha Microsoft uses. Where can I found a detailed discription of the algorithms? Is there any good explanatory report for the algorithms and results?
Does anyone know where we can get more in-dept tutorials for the Data Mining Add-Ins for Excel? Currently, all we have are the videos from the microsoft web site as well as some white papers.
Does anyone know how is forecasting defined in the Data Mining Add-In (Excel)? If we look to the web, we would see different Forecasting Standards. What specific Forecasting algorithm and standards used in the Forecasting in the Data Mining Add-In (Excel)?
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.
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.
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 downloaded a trial version of office 2007 and the data mining addin. I do not have an automatic connection to Analysis Services, so most functionality does not work. Is it possible to configure a connection with a trial version? If so, does anyone know what the server name is and how to configure it?
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 have installed the excel DM addin and am trying to work through the tutorials -
When I run the 'Analyze Key Influencers' tool against the sample data through a remote AS server I get: The task was not able to detect any key influencers for the 'Purchased Bike' column. The values of 'Purchased Bike' seem unrelated to values of other columns.
however when I run it against a local AS server I get the expected results.
I can see no differences in settings or setup between the AS instances I am trying to use - perhaps a permissions issue? Thank you
With SASS Database i have created Data mining Structure Using Time series algorithm, while processing the SSAS db, Data mining  taking long time to process, so how we can  reduce processing time ???
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?
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?
I am trying to delete tables from data where the ModifiedDates older than 9 years in AdventureWorks2012 database . I get console notified that foreign keys are dropped but the delete statement is throwing errors. I am sure that somewhere the key constraints are not getting altered, but i'm not able to figure it out as i'm a relative beginner to T-SQL. The error and code:
The DELETE statement conflicted with the REFERENCE constraint "FK_SalesOrderHeaderSalesReason_SalesReason_SalesReasonID". The conflict occurred in database "AdventureWorks2012", table "Sales.SalesOrderHeader [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null $option_drop = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions; $option_drop.ScriptDrops = $true;
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.
hi I am new at MSSQL 2000 DBA thing. and trying to learn more about analysis service/data warehouse/data mining. so is any expert out there can Recommend some good books or web link article to read? Thanks
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:
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:
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?
I've created a Cluster data mining model and seems to correctly return data. However I've created a data mining dimension and cube but when I go to query the cube it doesn't return any data if I select any members on the data mining dimension. Any suggestions to where I can look to resolve this?

I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected. It seems that somehow the 3 columns are not read in from the source file? ans alslo fiscal year, fiscal week is not set up up properly in my data destination? anyone faced such errors before?
