Mining Model Prediction... what for?

Which Data Mining algorithm use Mining Model Prediction?

Every algorithm has to use Mining Model Prediction for a final goal of a Data Mining Project?

Mining Model Prediction Results

Feb 11, 2008

Is there a way to display the actual predicted value for an output attribute for a particular model. For example, say I am trying to predict if a particular customer is going to take advantage of a promotion (0=no, 1=yes) and I use neural networks. I know that I can use "Predict" to give me the prediction "yes" or "no" for each customer. However, the neural network actually spits out a number as a result. For example, a 0.997 would be interpreted as a "yes" for life insurance promotion. I do not want the probability that the prediction is correct. I want the actual output for the network.

The reason being is that I want to compute an error rate between the predicted value and the acutal value (root mean squared error or some other measure). Is there a way to compute this using the mining model prediction tab design view? I do not want to write the actual query as I teach a course in data mining using SQL Server and my students do not know DMX queries.

Thanks for any help you can provide.

Retaining Fields For Multiple Models In Mining Model Prediction Tab Design View

Nov 29, 2006

I am using BI Dev Studio for SS2005 in a research (as opposed to a production) environment. Often I want to compare the results of multiple models using the same attributes. If I switch to a different model, the Design view completely resets. Is there any way to retain the same field names with different models in the Design view?

My current workaround is to give my models similar names with AR, DT, CL, LOG, NN suffixes and make global changes in the DMX.

I have consulted the following without finding an answer:

Using Cube Views As A Data Source To Build Mining Model

Nov 16, 2006

Hi all,

I am new to SQL Server 2005 Analysis Services and would like to use the OLAP Cubes as a datasource to build Mining Model . However i would like to use a particular view of the OLAP cube that i have generated to be used as the datasource for the mining model . I find that i am not able to save the Cube View while browsing the OLAP cube in Business Intelligence Studio. Is there a way i can acheive this requirement.

Any ideas regarding this will be really appreciated.

Viweing Prediction Value In The Textbox After Predicting With Time Series Alforithm

Dec 24, 2007

Hi
In this site sample ��generate DMX creation statement for a server mining structure and contained model�? I didn��t understand, what is output? You say output is like a table, but I don��t know what usage of this sample is because my request was about showing the result of time series algorithm. please notice my question, I should use a query like this for connecting with forecasting model
��SELECT
PredictTimeSeries(amount)
From
[Forecasting]�?
And then save this value in the text box?
Also I should have training for showing value in the text box, which stage I should do it, this stage is after creating model or no?
In time series algorithm, training is equivalent of historic prediction?
In this code why these items are unknown and after running we have error
In server. Connect for server and in database db for database and in MiningStructure ms for MiningStructurewe have error .

private void button1_Click(object sender, EventArgs e)
{
Microsoft.AnalysisServices.Server server = new Server();
server.Connect("data source=localhost");
Database db = server.Databases["DMClass"];

foreach (MiningStructure ms in db.MiningStructures)
{
MessageBox.Show("Processing " + ms.Name);
ms.Process(ProcessType.ProcessDefault);
}

MiningStructure msIris = db.MiningStructures["Iris"];
MiningModel mm = msIris.CreateMiningModel(true, "newModel");

mm.Algorithm = MiningModelAlgorithms.MicrosoftClustering;
mm.Update();
mm.Process(ProcessType.ProcessDefault);

server.Disconnect();

}
Please alittle define this code.
What is diffrence between amo and adomd ?
And for viweing prediction vlue in textbox and connecting I can use both of them
And how can I build a child form?Thanks a lot for your answers

A Time Series Prediction Was Requested With A Start Time Further In The Past Than The Internal Models Of The Mining Model

Feb 19, 2008

Hi all,

I have a very simple time series model which processing works fine without any problem. However when I run the following query

SELECT

[TimeSeries].[PriceChange],

[TimeSeries].[Symbol],

PredictTimeSeries(PriceChange, -3, 2)

From

[TimeSeries]

WHERE

[TimeSeries].[Symbol] = 'x'

I get the following error:

TITLE: Microsoft SQL Server 2005 Analysis Services
------------------------------
Error (Data mining): A time series prediction was requested with a start time further in the past than the internal models of the mining model, TimeSeries, specified in the HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process.

The following is the excerpt of the minding model script related to the two parameters:

<AlgorithmParameters>

<AlgorithmParameter>

<Name>MISSING_VALUE_SUBSTITUTION</Name>

<Value xsi:type="xsdtring">Previous</Value>

</AlgorithmParameter>

<AlgorithmParameter>

<Name>HISTORIC_MODEL_GAP</Name>

<Value xsi:type="xsd:int">1</Value>

</AlgorithmParameter>

<AlgorithmParameter>

<Name>HISTORIC_MODEL_COUNT</Name>

<Value xsi:type="xsd:int">10</Value>

</AlgorithmParameter>

</AlgorithmParameters>

These HISTORIC_MODEL_GAP (1) and HISTORIC_MODEL_COUNT (10) should accommodate PredictTimeSeries(PriceChange, -3, 2). Could anyone shed some light on this?

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?

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.

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.

Association Model Prediction Not Using Itemsets

Dec 31, 2006

I have a market basket model using associations. It generated several dozen itemsets. However when I attempt to run a singleton prediction like this:

select (Predict(Orderproduct3q,INCLUDE_STATISTICS,10)) as [Recommendation]

From

[Case All]

NATURAL PREDICTION JOIN

(SELECT (SELECT '16407' AS [Pname])) AS t1

the resulting predictions don't take the itemsets into account. Instead, the predictions consist of the ranked products in the training set, ordered by frequency. This appears to happen regardless of the precise query specified within the "natural prediction join".

What's going on here and how do I generate a singleton prediction which makes use of the itemsets?

Prediction Query For A Weighted Clustering Model

Dec 12, 2006

I have a question about writing a prediction query against a clustering model that has the same column added more than once.

Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look? If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query?

Problem With Historical Prediction In Sales Forecast Model

Aug 2, 2006

Hi,

I have built a time series model to forecast sales value

I have data from jan 2004 to jan 2006 and the sales value is
at a day level in my database. But I am aggregating it to month level in the
DSV of the mining model.

I am required to make only historical predictions using the
above model starting form jan 2004 to jan 2006 for every month.

I have set Historical_Model_Count
and Historical_Model_Gap parameter
values to 24 and 10 respectively, and trying to predict for the past few months
(PredictTImeseries(SalesValue,-1,1))

But its throwing me the following error

Error(Data Mining): A time series
prediction was requested with a start time further in the past than the
internal models of the mining model, Sales Forecast, specified in the
HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process

In fact it throws the above error irrespective of what the Historical_Model_Count and Historical_Model_Gap parameter values
are

I am not able to figure our why this problem is happening?

What should the parameter values for the above scenario?

It would also be helpful if I can get an explanation on how
these two parameters affect the historical predictions. I kind of understand
that these two parameters are important for historical predictions but don��t
know why or how.

Datamining Model Automatically Add Space To Field Name. Can't Use Prediction Join With Original Table

Aug 30, 2007

Dear All,

I have a database table which has all the inputs, key and the result. In visual studio, I created a decision tree model which has exactly the same fields as in the table. However the visual studio automatically add space preceding the capital letters. As the field name in the Datamining model and those in the database table are slightly different. I cannot use NATURAL prediction join. Is there anyway to told the visual studio not to add the spaces in the variable names?

Thanks and regards,

Is The Operation CREATE MINING STRUCTURE And CREATE MINING MODEL Really Useful?

Aug 17, 2006

Hi,

I've tried those two operations in the Management Studio.
Though we can create a mining structure and mining model in Management Studion,
but we cannot process the analysis-service database.

(1) I create only a mining structure through CREATE MINING STRUCTURE.
No error reported. But if I process the analysis-service database in Management Studio I always get error

'Error : The '<mining_structure__name>' structure does not contain bindings to data
(or contain bindings that are not valid) and cannot be processed.

I then tried to create it by creating and running an XMLA script. It was successful.
However, it's much harder to learn XMLA.

If any of you created an analysis-service database in Mgt Studio, and create a mining
structure in the same place using DMX script, can you process the database?

(2) Is there any use of CREATE MINING STRUCTURE operation without binding
to any table? Examples I saw so far did not show relating it to do. In my experience
processing the analysis-service database with that mining structure is doomed to fail.

(3) Is there any way we can create mining structure through CREATE MINING

STRUCTURE operation in Management Studio and use RELATED TO clause

to bind it to any Relationship to an attribute column (mandatory only if it applies), indicated by
the RELATED TO clause

(4) If this is the fact, is there any use of CREATE MINING STRUCTURE operation?
If we use BI Dev Studio, it's much easier to use the wizard.

(5) I found I cannot create a mining model inside a mining structure through operation
CREATE MINING MODEL. If you call that operation, you end up having a mining
model and a mining structure with the same name. I found that in order to create a
mining model inside a mining structure you have to call operation ALTER MINING
STRUCTURE ADD MINING MODEL. Is it true this is the only way?

Thank you,

Cannot Build Data Model

Jan 24, 2007

This may be a noob question... but I am not able to create a data model and its frustrating me. :)

I made the Data Source... I made the Data Source View (just grabbed a table) and made the report model... but the model is empty >< When it autogenerated the model, it did yell at me about the table not having a primary key... do all the tables have to have primary keys???

Please help I'm a bit lost.

Report Model - No Build Because Of Error In Role

May 8, 2007

Hi,

I removed a role in the datasourceview of a datamodel. Later I removed the role in the reportmodel. There are always two roles for one relation. Now I only have one role left and I can't delete it anymore.

This is the error I get when building the project.

Error 2 The RelatedRoleID property of the Role 'invoicelineid' refers to the Role 'Gd1b03590-f98b-46aa-945d-c90ccd5d6028', which is not in the same SemanticModel as the Role 'invoicelineid'. Max generiek.smdl 0 0

When I try to remove the role I'll get an error : object reference not set to an instance of an object.

If I look at the properties of the role I see that when I open 'related role' there is nothing in it, except an ID: Gd1b03590-f98b-46aa-945d-c90ccd5d6028 and as name: Object reference not set to an instance of an object.

I also tried to remove the whole entity but that resulted in the same error. It's not an option for mee to remove the whole model and autogenerate it again, but there is too much work in it already.

If I try to remove this thing in the xml itself it gives other errors and the model won't load anymore.

I hope somebody has a solution for this.

thanks in advance,

Mining Model?

May 17, 2007

Hi,

I'm working on a project to create a mining model.I have one "flattened" table with a productID (key) and related attributes. Example columns are weight, color, price, units sold last year, product category, product rating (top seller, etc) and similar columns, about 40 in total. There are about 15,000 products and same number of rows in the table.
The objective is to pass a ProductID (that also exists in the table) and get back the top N products that most resemble the source product based on all the attributes.

Any advice on which models I should test and how to set up the models would be much appreciated. Also if there is a similar example/sample out there, please let me know. I downloaded the MovieClick sample, but that doesn't work in my case as I only have the equivalent of the Customers table.

Thanks in Advance.

Mining Model Parameter

May 24, 2007

I have one main mining structure and several mining models that are using the MS Decision Trees algorithm. I have a Reporting Services report that displays the model using a table. I want to set it up so that in the DMX query, I can use a parameter to specify which model to use. That way I just have one report that can reference multiple models. For example I would like to do something like this:

SELECT FLATTENED * FROM [@model].CONTENT

This doesn't work because I get the error message:

Preparation of DMX query failed. Error (Data mining): Either the user, user, does not have permission to access the referenced mining model, @model, or the object does not exist. (Microsoft SQL Server 2005 Analysis Services)

We are running SSAS 2005 SP2. Is there a way to accomplish this?
