Where Can I Store The Mining Results From Mining Models In SQL Server 2005 Data Mining Engine?

Apr 26, 2006

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.

Quesion On Algorithm Settings Do Not Really Significantly Improve The Results Of The Mining Models?

Jul 16, 2007

Hi, all,



Another tricky confusion to me is that: many algorithms settings for the native algorithms in SQL Server 2005 Data Mining do not really significantly improve the results of those mining models with settings changes? (Apart from clustering algorithm setting of cluster number, by setting 0 as the number of clusters, the system will automatically cluster the data into clusters which I assume is the best way of mining the model with this method).



Any good advcies on this will be a lot appreciated.



I am looking forward to hearing from you shortly for this confusion and thanks a lot in advance.



With best regards,



Yours sincerely,

Data Mining :: Informational (Data Mining) - Decision Trees Found No Splits For Model

Sep 29, 2015

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.

Data Mining - Scalar Mining Structure Column Data Type Error...

May 31, 2006

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?

Data Mining :: MS Excel Data Mining Add-ins / Maximum Number Of Predict Columns

Jun 4, 2015

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.

Data Mining :: Implementing Excel Data Mining In A Classroom Setting?

Jun 15, 2015

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?

How Is The 'Score' Value Derived In The Lift Chart/Mining Legend For Data Mining Models?

Sep 26, 2006

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 cant 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, 2007

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?

Can I Filter The Data On Mining Structure, Mining Model?

Jul 18, 2006

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.

How To Access The Data From A Custom Data Mining Plugin ?

Dec 20, 2006

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.

Data Mining :: How To Mine Data From One Spreadsheet And Place It In Another

Jun 15, 2015

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?

Excel Data Mining Add-in For Categorical Data

Jul 24, 2007

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.

Excel Data Mining Add-in For Categorical Data

Aug 5, 2007

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

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.
Best regards,

Data Mining

Apr 23, 2006

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,

Data Mining How To

Jan 30, 2004

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.
