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 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

Error In Mining Accuracy Chart

Dec 15, 2006

I ran a decision tree, clustering and neural network mining model across a dataset of about 200,000 records. I am trying to evaluate the accuracy of each of my models but I can't view the results.

I get the following error:

Failed to execute the query due to the following error:

Lift Chart / Data Mining Legend

Jul 17, 2006

Hi,


I am having trouble really understanding what makes a model accurate and effective at predicting some attribute. I can't seem to find any clear documentation about the mining legend of the lift chart on the Mining Accuracy Chart tab when working with the Data Mining Structure designer in VS 2005. Specifically, I would like to know more about what numbers in the Score, Population Correct and Predict Probability columns mean, and why they change when you move the vertical gray bar on the Lift Chart. Also, what is generally a good score to be aiming for, provided that it is highly difficult to get 100% accuracy with the kind of data that I am using.

Any more information on this subject is much appreciated. Thank you for your time,

Chris Burns

Data Mining Lift Chart Problem On Vs2005

Jun 4, 2006

Hello . Because of my graduation project , I interested in data mining application , Adventureworks DW on MS VS 2005 . I opened File->Open->project/solution ->Enterprise -> AdventureworksDW .then I successfully deployed the algorithms decision tree and Clustering . Then I opened tab Mining Accuracy Chart then selected input table "testing" , which I had created before ,  from vTargetMail . After that , mining structure table and target mail table has automaticaly linked each other .Next , I selected predictive input as 1 , of the predictable row "BikeBuyer" . But , when I clicked "Lift Chart ", I only got a 45 degree line , everytime .. How can I fix it ?

Mining Accuracy Chart, Predictable Column In Nested Tables

Oct 27, 2006

In the Mining Accuracy Chart, the predictable columns of nested tables does not show up in the "Select predictable mining model columns to show in the lift chart" table. The "Predictable column name" is empty.

Predictable columns in the case table shows up, but not the predictable columns in the nested table. What am I missing?

Hi,I am studying data mining features of SSAS and for a workshop I'vecreated 2 views derived from vTargetMail view of AdventureWorksDW.Train data consists every record except those in Pacific, and testview consists only records from Pacific area.1. I've created a mining structure based on Decision Tree and selectedBikeBuyer as predictable column.2. According to input column suggestions, I've selected Age,Eng.Education, NumberCarsOwned, YearlyIncome, CommuteDistance,NumberChildsatHome and TotalChildren as input columns,3. I've modified no other setting, and deployed project.I can get training results in decision tree browser and dependencynetwork (and both seem to give rather logical results) however, when Itry to browse lift chart or classification matrix I get an emptyclass.matr. and a lift chart of a single 45 degree line.Am I missing a step, or must I do some fine-tuning on (what)parameters?Thanks...

Question On Column Mappings Between Mining Structure And Case Table For Lift Chart

May 3, 2007

Hi, all experts here,

I am a bit confused for the model evaluation (lift chart), should we map all the columns for both the mining structure and the case table? I mean for those predictive models, we have a predict column, shouldnt we ignore the mapping of the predictive column between the mining structure and the case table? But it seemes we are not allowed to miss the predictive column mapping between the mining structure and the case table.

Why is that? Could any experts here give me some explanation on that?

Hope my question is clear for your help.

Thanks a lot and I am looking forward to hearing from you shortly.

With best regards,

Yours sincerely,

Infromation About Accuracy Of The Mining Model Problem

Dec 23, 2005

Hello!

I have a problem getting information about accuracy (percentage of the right predictions) of the model using DMX. Is it possible to get information about accuracy of the model using DMX? I didn't find any useful function... My second idea was to build and process the model. And then compare states of the predictable columns of the test data to states that the model predicts on the same data. And count them. That would be the way to get percantage of the right predictions... The problem is that usage of the function COUNT is not allowed??? I tried:SELECT COUNT(*) FROM [My Model Name].Cases and it didn't work like in standard SQL...
Is it possible to count rows in DMX? Any idea how to get accuracy (percentage) of the model? I would need this information in my application...
Thanx for any idea,
Ziga

Lift Chart Failing With Restricted Security Model

Jan 4, 2007

Hello--

We're running into an issue where analysts are having problems obtaining lift charts (via the Mining Accuracy Chart UI available in the Visual Studio Analysis Services project) and performing prediction (via the Mining Model Prediction UI).

The issue seems to be related to the underlying analyst security model. Note that this post is related to:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=924641&SiteID=1


Analysts that work on the same problem will only have access to:

- A sandbox relational database (which contains views into the same source database). The analyst is db_owner of the sandbox database, so she/he can create data transformations required, etc. The sandbox database contains views to the source database, but the analyst only has read-access to the specific data elements needed from the source DB. So, they are very restricted w.r.t. the source database, but are db_owners of their sandbox relational databases. Note that the analyst will connect to he database via Windows Authentication.

- An Analysis Services sandbox database to use for their modeling, etc. In this AS sandbox db, we've created a role called "Administrator" and checked the permissions: Full control (Administrator), Process database, and Read definition. The analyst's windows account is the "user" associated with this role.

Also, in this situation, the SQL Server 2005 Relational Engine and Analysis Services are running on a single machine. The goal of this security model is to provide analysts with the ability to work in their "workspaces" (both SQL and AS), but not to see other analysts work, etc.

Under this model, Analysts are able to deploy mining models when the Data Source object that points to their relational "sandbox" DB is set-up with "Impersonation Information" = "Use a specific user name and password", where the Analyst provides their domain account information.

But, when trying to build a lift chart using the same data source view objects that were used to successfully train the model, the following error is occurring consistently:

Window Title: "Loading Mining Accuracy Chart"
Window Text: "Failed to execute the query due to the following error: Execution of the managed stored rocedure GenerateLiftTableUsingDatasource failed with the following error: Exception has been thrown by the target of invocation. Either '<domain><login>' user does not have permission to access the '' object, or the object does not exist. 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.."

Since the Analyst was able to build the model with her/his given '<domain><login>' credentials, it is puzzling why the lift chart is failing.

Thanks in advance for your help,

Datamining Advice On Choosing Mining Model

Nov 30, 2007



Hi--

I am a newbie to datamining, but have nearly a decade of solid database experience with the last 6 years in SQL Server 2000. We are moving our accounting system to SQL Server 2005 and I have been asked to explore the possibilities of mining an inventory table. I'd like to get some opinions prior to spending too much time potentially barking up the wrong tree!

We have an inventory table with approximately 10 million serialized records. Each row contains the serial number of the individual unit and its manufacturer/model designation. We have no control over the assigning of the serial numbers as they come from multiple manufacturers and some of the manufacturers correlate serial numbers to model and some don't.

My thought was to use a cluster model to try to predict the model of a new serial number as it is entered into the database. Is this thought feasibile? Is the mining model choice appropriate? If pointed in the right direction, I'm sure that I can run with this.

Thanks in advance-- Jim

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.

Build An Application In C# With Using Mining Model For Viweing Prediction Value

Dec 28, 2007


HI
Thanks a lot for your answer
I say my request but I don€™t know why anybody don€™t answer me
I have a project about predicting a value about selling and buying of a good like t-shirts and I use data mining for my project ,so I should use time series algorithm ,that €˜s mean I have previous data about t-shirts for 11 months ago and now I should say for 12th month ,how many t-shirts are sale?
My tables saved on the excel file and it is problem, because how should I use this table for building model?
After building a model and structure and predicting the value of 12th month for this store in the mining model then I use this query in model in bi:
€œSELECT
PredictTimeSeries(amount)
From
[Forecasting]€?
This query showed a column and prediction value.
After all of that now I should show this value in the application so I use c# language for building it, so I use a form in c# then I add a button to form that with clicking on this button, I can connect to my structure and then show process of connecting in the panel, then with clicking on the other button I can use this query
(€œSELECT
PredictTimeSeries(amount)
From
[Forecasting]€?
) and after using I can see prediction value in the textbox, that€˜s mean the value of 12th month show on textbox.
Form has two buttons: one button is for connecting to mining structure and other button is for sending PredictTimeSeries query to structure, one textbox, which is for showing the predicting value for 12th month for selling t-shirts, one panel for viewing the lift chart.
Also you say
You are building an application that programmatically creates mining structure and a model, and then you want to train the model and display some results.
And I don€™t know how can I train my model, I should use a special code for it?
If your answer is say, please explain that and then say that codes are for training.
Please if you can send c# code for Sporadic of stage, please send that, I need to this code; my request is emergency for me.
Thanks a lot
i am very sad because any body don't answer me

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:

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.
Best regards,

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.

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>

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?

Problems With Neural Net Viewer, Lift Chart And Predictions Still Ocurring In SP2

Nov 24, 2006

Greetings,



I have a mining structure that I am using to perform a text-mining
classification task. The mining structure contains three models: a
decision tree, a naive bayes and a neural network.


Both the decision tree and the naive bayes models process without
any problems, but I am having significant difficulties with the neural
network model.


Initially when I processed the model, processing would fail altogether with the following error message:



"Memory error: Allocation failure : Not enough storage is available to process this command"



This was remedied by taking the steps prescribed in
http://support.microsoft.com/kb/917885 (I upgraded to SQL 2005 SP1 and
applied all available hotfixes listed in
http://support.microsoft.com/kb/918222/). This got me to the point
where the model (seemingly) processed correctly after restricting the
MAXIMUM_INPUT_ATTRIBUTES to a relatively low number. So after
processing, I went to try and browse the neural network model and view
the lift chart...



<error>

"Execution of the managed stored procedure GetAttributeScores
failed with the following error: Exception has been thrown by the
target of an invocation.Input string was not in a correct format.."

</error>



(see http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=935340&SiteID=17)



Also when I would attempt to view the lift chart and the
classification matrix the queries would time out with the following
error message:



<error>

XML for Analysis parser: The XML for Analysis request timed out before it was completed.

Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.

</error>



Now, my poking around on Technet lead me to believe that this issue
could finally be resolved by uprading to the CTP release of SQL server
2005 SP2. Now I am still encountering problems. When I go to browse the
model in the Neural Network Viewer, I see the correct drop down menus
to select attributes and attribute values in the "Input" and "Output"
panes but I see no data displayed in the "Variables" pane at the
bottom.


Interestingly, while I cannot view the model contents in the
graphical viewer, the mining model contents viewer reveals model
contents that look to be pretty normal for a trained neural network.



Attempts to view the lift chart time out with the error message:



<error>

XML for Analysis parser: The XML for Analysis request timed out before it was completed.

Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.

</error>



and when I run predictions against the trained NN model in the
"Mining Model Prediction" pane it predicts the same value for every
case in the testing set.



Any thoughts?
