Hi, all here,
I currently have a question about unknown member in cubes (as we know, there is always an additional member called unknown in an OLAP dimension)for data mining. I mean is there any way for us to deal with unknown member in cubes when mining cubes?
Thanks a lot in advance for any guidance and help.
Hi,
I'm using MS Report Designer 2005 and have created a report that uses a cube, with a dimension set up to convert null values to unknown (nullProcessing = UnknownMember).
When I create a parameter using the checkbox in the graphical design mode's filter pane, Report Designer automatically sets the constrained flag, eg:
STRTOMEMBER(@DimOrganisationBUSADDRSTATE, CONSTRAINED).
When running the report and selecting the 'Unkown' value from the parameter list, the error 'the restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated' occurrs.
How can I prevent the constrained flag from being used, or am I doing something wrong with converting null values to 'Unknown'?
Thanks
Uknown Member is set to "Uknown" in the cube . This cannot be changed because it needs to be visible in other applications. However, in my particular MDX I want to create a custom set that excludes this member.
WITHSET setNoUnknowns as EXCLUDE( [Dim].[Hierarchy].CHILDREN, { [Dim].[Hierarchy].UNKNOWNMEMBER } )SELECT{[Measure].[MeasureName]} on COLUMNS,setNoUnknowns on ROWSFROM [Cube]
With the above MDX, I still get a return for member "Unknown". I've confirmed that there isn't an explicit member name of "Unknown".Excluding [Dim].[Hierarchy].[Unknown] does not work either.
While creating a model, i can access to relational tables as data source, but not to olap cubes. Is it possible to browse olap cubes for mining? If yes, how? Thanks...

Thanks,

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 need to create a member that one of its Attributes (maybe my term is wrong) is a reference to another entity member named group
the code
createRequest.Members.MemberType = MemberType.Leaf;
createRequest.Members.Members = new System.Collections.ObjectModel.Collection<Member> { };
Member aNewMember = new Member();
aNewMember.MemberId = new MemberIdentifier() { Name = uag.groupName, MemberType = MemberType.Leaf };
[code]....
"The attribute data type is not valid".Is it wrong to add the reference as attribute? How can I embed the reference in the new member?
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:
"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.
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 wizard
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.
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.
Is there a way to "bulk establish" the access credentials and establish those databases?
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 ???

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,

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?
First we need to run all packages for initial loading and then we need to run all packages every night.
But inside all packages we need to mark some records as invalid data.
How to deal with all these invalid data after data migration?
If I reject to transfer these data, I will get reference error during next data migration loading.
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.
Hi, all experts here,
Thanks for your kind attention.
I have a question on missing_value substitution. As we know in the algorithm parametres setting, there is an option for us to select the method to deal with the missing_value: None, Previous, or Mean. My question is: to numeric data column, we can select Mean method to deal with its missing value. But how about discrete type of data column? What is the best practice to deal with this kind of data? I do think it to a great extent matters the quality of the models being trained?
Can please any of you guys here give me any advices and suggestions on this based on what best practices you have got?
I am looking forward to hearing from you shortly and thanks a lot in advance.
With best regards,
Yours sincerely,
First a bit of background.
We use the Windows-logon to authenticate en identify the user. With this logon we check within most of our reports what a user is allowed to see.
Depending his level or geographical location he is allowed to run reports on one to all sites. He can selects the sites from a Multiple Select box. This works fine.
Now, we want to use data-driven subscriptions, I understand why we can't use this parameter, but how do you people deal with this kind of configurations.
I would prefer not to 'double' the reports in a normal and a subsciption version .....
Hi,
Does anyone know how to deal with image data type within stored procedure when using SQL2000?
I have a table and there is an image data type column. In this table I need to make a copy of one row within a table through a SP /it means to retrieve the whole row within SP, change another columns data (but, that the image is not modified) / and save the modified row back to the same table.
Problem is, that within SP is not alowed to use local varaibles of image data type. Does anyone know a solution for this? Please.
Thank you.
I have added a page refresh in combination with 'Command Notification' to ensure that my data is fresh,( it is updated on the sql server database approx. every 5 mins).
However, I also allow filtering on the table contents and every time I refresh the filtering is lost. Is it possible to maintain the filtering through the refresh?

I have a table that I am exporting via a SQL server table to a csv file, via the flat file connection manager within SSIS. My issue is that one of the fields in my table contains "," (commas), so when the file is created it creates new columns in the csv file because the field is "," comma delimited on the column. Is there anyway to get round this without having to get rid of commas in my table (which I've tried and works)?

On the subject of Data Warehouses, Data Cubes & OLAP….I would like to speak frankly about Data Warehouses, Data Cubes andOLAP (on-line analytical processing). Has it dawned on anyone elsethat these buzz words were created by some geek who decided to take astab at marketing? Knowing that to the backwoods manager who knowslittle of technology that new innovative names for old concepts wouldhelp to sale their products.I mean seriously, what is the story here? In a nut shell, and pleasestop me if you disagree, but isn’t a data warehouse simply adatabase? Can’t you do everything on a conventional databaselike SQL Server, Oracle or DB2 that you can do on these newproprietary Data Warehouse constructs? I mean who are they trying tofool?Take a look, for instance, at Data Cubes. Who hasn’t noticedthe striking similarity between data cubes and views used in all themore robust databases? Also, what about OLAP? OLAP is nothing morethan a report generator. There’s nothing you can do with thesemillion dollar price tagged Data Warehouse total solution packagesthat I can’t do with SQL Server, Oracle or DB2…for thatmatter Microsoft Access.As an example some sales people for Metadata Corporation has the VicePresident of I.T. in Nashville, for Healthspring, sold on their totalsolution data respository which is such a scam. All they had to dowas throw a couple of buzzwords at him and they have him hypnotized.Personally, I feel that these kinds of marketing practices undermineour industry. It helps to unravel what little standards orconsistency we have. What do you guys think?Stuart

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.
