Changing Algorithm Parameters With BI Dev Studio Extensibility
Jan 28, 2008
I'm looking for ways to enable business users to change algorithm parameters in a "high-level way" with the UI presenting some domain-specific blurb and sliders. Is it possible to create a Visual Studio package or add-in for Business Intelligence Development Studio that can change algorithm parameters? Can the Visual Studio SDK or Shell be used for that? Is documentation available?
Also, is the Business Intelligence Development Studio changing with SQL Server 2008 and Visual Studio 2008?
All -- Please help. I need to know how to check old-value VS new-value for a Linq-To-SQL OnValidate Extensibility Method. Below is some sample code that shows, more-or-less, what I am trying to do.public partial class MyObject{ #region Extensions
partial void OnValidate(System.Data.Linq.ChangeAction action) { if (action == System.Data.Linq.ChangeAction.Update) { if ((Ssn_Value_Old) == (Ssn_Value_New)) { //Continue. The new-value is the same as the old-value; so, do not bother checking for existence. } else { if (this.IsExistingSsn(Ssn_Value_New)) { throw new System.ApplicationException("The input is not valid. The new-value for the SSN is already existing."); } else { //Continue. The new-ssn does not already exist. } } } else { //Continue. This is not an update operation. } }
#endregion //Extensions}
Do you know how to do this without a separate lookup? Please advise. Thank you. -- Mark Kamoski
I have two parameters on a report, which are independent of one another, yet when I change one, the current report refreshes, and I'm left with a blank screen. What is causing the refresh behavior on this report? It appears as though it is treating them as cascading parameters, but I don€™t use one to filter the other. Since the report has default values, when first navigating to the report, it displays just fine. I would like the user to be able to change the first parameter without the report refreshing to a blank screen. Once it refreshes, they can click on the €œView Report€? button and see the report, but I would like for the current report to stay there, which is the case on my other reports, until they click the button. Any ideas?
Can I change the chart type with the value supplied in the Report Parameters ? Other than chart types everything else have expression field attached to them. Please Help !
I'm new to SQL Server....running SQL Server 2000. Had to move the system database logs to a different drive. Used EM, Server properties, Startup parameters. Changed the transaction log designation. Closed that window. Stopped the server.
Server won't start as I messed up and did not include the file name in the new designated path....just down to directory level.
From what I've seen, I have to be able to start the server service to change the parameters and the server won't start.
Is there a file that contains these parameters I may edit or should I try using the command line options.
I have a stored proc which will be fed a value that is compared to a char value for a selection. One of the choices might be 'all' for which I want to return all records. Something like this
create procedure name @location char(40) as select ----------------
where locname like @location
I tried using LIKE COALESCE but no luck. Any ideas Thanks
I think it has been discussed previously that having default parameter values based on expressions, e.g. a default parameter value of =Split("Bug",",") in multiple parameters will cause a postbacl whenever a user selects different values from the list.
Is this by design? Its a bit of an annoying thing. The refreshpostback doesnt happen if you have basic defaults like ="All" but only when an expression of some sort is used in more than 1 parameter. Does RS think they are linked or something, why does it need to psotback efresh?
I can easily move "Table1", with schema "dbo", into schema TestSchema. But I can't see how to do it using only the GUI tools provided in Management Studio. Any ideas?
I have a report I want to modify and when I go to deploy it I get:
Changing the report parameters or data sources to the values you specified is not allowed. The report is configured to run unattended. Using the specified values would prevent the unattended processing of this report
Now I understand the error, it is because on the report server's web management interface I entered credentials for the report to run that point to a custom datasource and supplied the appropriate credentials to run the report.
However, I don't want to have to reconfigure that just to deploy a slightly modified version of the report.
How can I get around this? Or what is the proper work around? I just want to change the background color from dark gray to light gray on a header column....
Is it possible to use parameters in MDX Studio? I've tried using SSRS2008 for query design but... SSRS2008 query designer complains that parameters do not exist when they quite obviously do ( in the report)Â LaCie drives. Failing when you need them most."La" meaning "Terrible", "Cie" meaning "customer service"
I am new to DM and I am not sure which algorithm would be best to use.
I am trying to build a custom comparitor application that companies can use to compare themselves against other companies based on certain pieces of information. I need to group a company with 11 other companies based on 6 attributes. I need the ability to apply weightings to each of the 6 attributes and have those taken into consideration when determining which 10 other companies each company is grouped with. Each group must contain 11 members, the company for the user logged in and 10 other companies that it will be compared against.
At first I thought that clustering would be a good fit for this but I can not see a way to mandate that each cluster contain exactly 11 members, I cannot see a way to weight the inputs, and I think each company can only be in one cluster at a time which do not meet my requirements.
Well, i have read in claude seidman book about data mining that some algorithm inside in microsoft decision tree are CART, CHAID and C45 algorithm. could anyone explain to me about the tree algorithm and please explain to me how the tree algorithm used together in one case?
Hello,Do you know if the algorithm for the BINARY_CHECKSUM function in documentedsomewhere?I would like to use it to avoid returning some string fields from theserver.By returning only the checksum I could lookup the string in a hashtable andI think this could make the code more efficient on slow connections.Thanks in advanced and kind regards,Orly Junior
What kind of algorithm does the MAX command uses? I have a table that I need to get the last value of the Transaction ID and increment it by 1, so I can use it as the next TransID everytime I insert a new record into the table. I use the MAX command to obtain the last TransID in the table in this process. However, someone suggested that there is a problem with this, since if there are multiple users trying to insert a record into the same table, and processing is slow, they might essentially come up with the same next TransID. He came up with the idea of having a separate table that contains only the TransID and using this table to determine the next TransID. Will this really make a difference as far as processing speed is concerned or using a MAX command on the same table to come up with the next TransID enough? Do you have a better suggestion?
I have few questions regarding Clustering algorithm.
If I process the clustering model with Ks (K is number of clusters) from 2 to n how to find a measure of variation and loss of information in each model (any kind of measure)? (Purpose would be decision which K to take.)
Which clustering method is better to use when segmenting data K-means or EM?
I want to predict which product can be sold together , Pl help me out which algorithm is best either association, cluster or decision and pl let me know how to use case table and nested table my table structure is
hi, i am using sqlserver2005 as back end for my project. actually we developing an stand alone web application for client, so we need to host this application in his server. he is not willing to install sql server 2005 edition in his sever so we r going by placing .mdf file in data directory of project.
but before i developed in server2005 i used aes_256 algorithm to encrypt n decrypt the pwd column by using symmetric keys.it is working fine.
but when i took the .mdf file of project n add into my project it is throwing error at creation of symmetric key that "Either no algorithm has been specified or the bitlength and the algorithm specified for the key are not available in this installation of Windows."
i'm making my master thesis about a new plug-in algorithm, with the LVQ Algorithm. I make the tutorial with the pair_wise_linear_regression algorithm and i have some doubts. i was searching for the code of the algorithm in the files of the tutorial and i didn't saw it. I have my new algorithm programmed in C++ ready to attach him, but i don't know where to put him, in which file i have to put him to start to define the COM interfaces? And in which file is the code of the pair_wise_linear_regression algorithm in the SRC paste of the tutorial?
Obviosly for Person1 and 200501 I expect to see on MS Time Series Viewer $3000, correct? Instead I see REVENUE(actual) - 200501 VALUE =XXX, Where XXX is absolutly different number.
Also there are negative numbers in forecast area which is not correct form business point Person1 who is tough guy tryed to shoot me. What I am doing wrong. Could you please give me an idea how to extract correct historical and predict information?
Currently I want to run a vanilla multivariate regression and get some statistics back about the regression that is built. For instance, besides the coefficients, I also want the two-sided p-values on the coefficients and the R2 of the model.
I've tried playing with the Microsoft_Linear_Regression algorithm and have run into two issues. I'm doing all this programmatically using DMX queries rather than through the BI studio.
(a) I can never get the coefficients from the regression to match with results I would get from running R or Excel. The results are close but still significantly off. I suspect this is because the Linear Regression is just a subset of the Decision/Regression Trees functionality, in which case some kind of Bayesian prior is being incorporated here. Is that the issue? And if so, is there some way to turn off the Bayesian scoring and get a vanilla multivariate regression? I don't see anything in the inputs to the linear regression that would let me do this, and even running Microsoft_Decision_Trees with a few different settings, I can't get the output I'm looking for. If there's no way to turn off the Bayesian scoring, can someone explain to me what the prior being used here is and how Bayesian learning is being applied to the regression?
(b) Using the Generic Tree Viewer, I see that there are a few "statistics" values in the Node_Distribution, but I'm not sure what they're referring to. One of them looks like it might be the MSE. I could play with this some more to find out, but I'm hoping someone here can save me that work and tell me what these numbers are. Hopefully they will constitute enough information for me to rebuild the p-values and the R2.
I have a code for Nearest neighbour algorithm, I want to build a datamining algorithm using that code..
I have the following link that includes the source code for a sample plug-in algorithm written in C#.
(managed plug-in framework that's available for download here: )http://www.microsoft.com/downloads/details.aspx?familyid=DF0BA5AA-B4BD-4705-AA0A-B477BA72A9CB&displaylang=en#DMAPI.
But i am confused on where to insert my algorithm logic?
