Is there a Lift chart viewer like the model viewers that can be embedded within your windows apps ? If not, then can this be easily created via Adomd.net api calls ? Has anyone done this easily in custom DM applications ?
Hi, I am not getting Mining Accuracy Chart and Min ing Model Prediction Plz tel me how to do.And how to use the filter input data used to generate the lift chart and select predictable mining model columns to show in the lift chart
how can i change the language of lift chart for description of vertical axis and horizontal axis and howcan i see the script of this chart for time series algorithm
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,
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:
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.
Why the lift chart for my mining models evaluation does not have a random guess model line there? As normal, there should be lines like trained models, ideal model, and random guess model? Why is that? What did I miss? Could any experts here shed me any light on that.
Thanks a lot in advance for your advices and help and I am looking forward to hearing from you shortly.
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 ?
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.
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...

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.

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?
When I export the report in excel format the chart is displayed as picture. I want it to be displayed as editable chart.Does Office Writer work in this situation and did anyone use Office Writer to accomplish same type of problem.Is there any other method or product we can use instead of the office writer.
I need to create a chart with the following features
1) Bar chart that has data for 3 years (3 series) 2) Line chart that has the same data as per the above points on the bar chart but this is a running total. (3 series) 3) These data points are for the 12 months 4) there should be a secondary axis for the cumulative one
i don't know weather is it possible or not..but Can any One tell's me How can i refresh the Chart Values.. acutally what's happening..
i have two Chart in a reprot .. One is Main Category and other one is SubCategory... acutally what i want.. in Main Category chart sum of Quantities of Subcategory values comes in bar or any other format.. and when i click on Main chart any bar it's refresh the other chart and return the result of subcategory under that main category in details...
i don't know is this possible .. acutally i m very new in reproting.. infact that's my first report.. so i want to do this.. if any article or any help anyone can provide me..
I've generated some mining models against an OLAP data source (dimension). However, when I go to generate a lift chart, it seems that the only data source that can be used for input is the data source view (the relational database). Is that right? Or is there something I'm missing here.
I was figuring I'd use one slice to train the model, then another slice to test the accuracy of the results. But right now it's looking like I can't do that.
What can we tell from the lift value of the attribute value in Neural Network? (any so-called threshold of this lift value which identifies whether or not an attribute value is important or whatever to the selecte output attribute value?) I mean with lift value of a particular value, when we describe the characteristics of a segmentaion with Neural network, what can we actually describe it?
I just dont know what can we desribe this for the segmentation by neural network viewer?
I am looking forward to hearing from you shortly and thansk a lot.
trying to build Orgchart with MS Access columns: Name (text), Boss (data source, Name), Phone (int)
the question - how to avoid the "loop"?
1. prohibit choice for the current employee to choose himself as a leader 2. prohibit choice for the current employee to choose any subordinate level employee as a leader
VBA is not an option, we are planning to move this table to MS SQL server, so it should be a choice with "SELECT from Name...." with exceptions or any other checks with warning/error message...?
And I would like the table to be like the one below:
It seems to me that I have to do some sort of pivot with my dataset/query before I could use it for the chart. Any ideas would be highly appreciated. I really need help with this. Thanks in advanced!
With 2k5 I am trying to make the "Top N" operator, used in a chart "category," return only N categories. But it almost always returns more than N categories. Can someone explain the nuances of the Top N operator, so I can get past this?
I like RS for SQL server. However, I am surprised (and frustrated) how limited the chart capabilities are; perhaps we have been spoiled by Excel...
Anyway, is there any way to change the color of the chart bars programatically. I can select different schemas (excel, pastel, grayscale, etc) but I need to go a little bit further, is that much to ask?
Oh, by the way, we can't mix chart styles, can't we? Need to show a chart and a line in the same report...
I appreciate your help on this, hopefully any answers to my questions might also help with other RS users with the same needs,
Hey all, I'm in a bit of a problem. I have a set of data on an excel spread sheet and i want that data to make a chart on a user form. I figured out how to get a blank chart on the user form but don't know how to link any data. Anyone think they can help?
Hi folks, I have a Employee Master table named "Employee_Master". This has got the fields like as follows,
Employee_ID Employee_Name Reporting_To
Now I need a query that can help me to build up the organisation chart. I have a query that gives me some data......... Its like
select emp.employee_id,emp.employee_name, mgr.employee_name as reporting_manager from employee_master emp ,employee_master mgr where emp.reporting_to=mgr.employee_id
But the problem with this query is, it gives only 1:1 mapping. And my requirement is to build a tree structure.........
So please help me oput in this regard........
Please lemme know if the problem is not understood to ya guys.......
Thanks a lot for answering my previous questions. Here's one more thing that I need. I have my data in one table called as Team_Aggregate. The fields there are TeamID, Date (1st of every month), Permanent Employeed, Contractor, Open Positions, Total Employees, Max Posns.
Now, when a user selects some months data that he wants to display I want it to appear something like this -
Columns as Month Names (Jan 08 Feb 08...June 08) Rows as Team Name and each cell = Team Total for that month and the corresponding team. Can I do something like this in sql? I want to display the data on the web eventually where I am using Gridview with datasource and databind methods.
I have created an area graph.My requirement is the following:-
When the user moves his mouse over the graph on different points, the values corresponding to that points should be shown as a tool tip or as a textbox value.
Any idea to capture the values in the graph(Category,Series and Data values) and display them in a textbox or tool tip in a SSRS chart?
Can you have different scales on a bar chart. I want to chart sales and quantity. Oracle lets you label the top of the bar chart as money and the bottom as quantity.
I am dividing my sales by one million and quantity by one thousand to make them similar in size on the same chart. I am using the sum of the sales/1000000 as a point label. Is there any way to limit the number of decimal places displayed. Currently it is displaying something like 1.94889312043; 1.95M would be better.
I have got a query regarding SSRS report chart control. Can i have a chart with both bars and lines within it?
I have a dataset which has two columns as my outputs.Can i have a chart showing bars for one column and line chart for the other column in the same chart?
I created a graph which retrieves value from database.And currently,my axis is in ranged 0-10.But i have a doubt that my value in will exceed my maximum y-axis value 10..My question is, could it be possible that i make my y-axis dynamic??Thanks!!
Hello, I am working on generating a Pie Chart in Reporting Services. I want to display percentage (%) in the pie chart slices, rather than having the actual values, since it does not fit properly into charts. A percentage would be better as a report.
Hope the question is clear. I would be grateful to anyone who answers this question.
I have a chart that is created in SSRS with the size property set to '15cm, 8.5cm', I want to set the height based on a parameter that is passed to the chart ( so that it fits onto a 1 page report it is fed through to), I have tried putting =Code.SetChartHeight() in the height property but it brings up an error saying it needs to be in a format like '8.5cm'. The SetChartHeight() function just returns the height parameter + 5.
