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.
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.
Hi, all experts here,
I would like to know if there is any way to migrate third-party data mining packages with SQL Server 2005 data mining algorithms together then we can have a comparison among all of them to get the best results for training models.
I am looking forward to hearing from you.
Thanks a lot.
With best regards,
Yours sincerely,
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?
I'm a beginner with SQL 2012 SSDT & SSMS. I get this error message when I try to deploy my project:Â
"Error 6
Error (Data mining): KEY SEQUENCE columns are not supported at the case level. The 'Customer Key' column of the 'TK448 Ch09 Cube Clustering' mining structure contains content that is not valid.
0 0
"
I am finding it hard to locate the content that is not valid. I've been trying to find a answer for this problem but can't seem to find anything. How can I locate the content that is not valid and change or delete it so that I can deploy this solution?
Having successfully created :
- a data mining structure with about 80 columns.
- a data mining model using Microsoft_Decision_Trees with 2 prediction columns.Â
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 wizardÂ
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.
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.Â
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. Â
Is there a way to "bulk establish" the access credentials and establish those databases?

View 2 Replies View RelatedHi,
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,

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?
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.
Joe.
Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

I'm trying to use 2005 Integration Services to import data from a web address into a SQLServer 2005 database.
The address I want to download data from is http://www.nymerc.com/futures/innf.txt
I'm not sure how I am supposed to access the data on the website. What kind of connection manager do I use? Flat File? HTTP? When I try to use a flat file connection manager, I set the connection string to 'http://www.nymerc.com/futures/innf.txt', but when I click OK, the connection string gets changed to 'c:documents and settings....Temporary Internet FilesContent.IE5V01H744)innf.txt'
Is this expected?

Hi, all experts here,
I am wondering is there any way to select only a portion of a data set to train the mining model? In this case, I mean we dont need to split the dataset in advance, what I want to do is being able to select any random portion of a selected dataset to train a mining model. Any advices?

View 4 Replies View RelatedI'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.
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?
Clearly, my code isn't written as well as it should be. I don't understand enough about data access and could use some help.I have several database tables, but one primary table that is the most accessed. Generally, I need to build a list from the data based on some filter. I'm using a repeater control, since all I need to display per record is a name, maybe a city or birthday, and possibly a little graphic, and my customer doesn't want a grid type of display. The filter is determined by the page requested. The exception is a search page where the user builds the filter and a grid is used to display the results.The results always contain a link to a page that has more detail on the selected record. What is the best way to handle this? I'm still trying to get a handle on different ways to get data and I'm not doing much with caching. Would it make sense to keep the data in memory from the page that displays the list (or search page) to the detail page? What if the detail page is accessed directly, say from a bookmark? How do I cache this?I'm currently using strongly typed datasets.Below is an example of what I'm doing - this is from the code behind of one of the list pages - members with birthdays this month. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim theMonth As String = DateTime.Now.ToString("MMMM") Me.LabelMonth.Text = theMonth Dim MemberAdapter As New WAPTableAdapters.membersTableAdapter Repeater1.DataSource = MemberAdapter.GetBirthday("Female", DatePart("m", Today)) Repeater1.DataBind() Repeater2.DataSource = MemberAdapter.GetBirthday("Male", DatePart("m", Today)) Repeater2.DataBind() End Sub Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim person As WAP.membersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.membersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & person.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If End If End Sub Protected Sub Repeater2_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater2.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim person As WAP.membersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.membersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & person.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If End If End Sub It seems pretty simple and straightforward to me, but these pages shouldn't be crashing when the site gets busy, so I have to be doing something wrong.

View 5 Replies View RelatedHi 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.

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

Dear friends,
I encounter a serious problem.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Please help me.
Best regards,
Manolis
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.

Hi all,
I am new to replication and have a few questions.
1) Are there any "hooks" available to insert processing when a subscriber is about to copy data from a replicating site?
2) Is it possible for a subscriber to change only his local copy of the data - without replicating the changes back to the publisher?
I realise that once the data changes in one place it isn't really replicated anymore, and I realise that my limited knowledge of the subject might well mean I'm not even asking the right questions. Therefore, I shall try to describe as best I can my scenario.
I wish to use many servers for transactional input (to distribute the workload) and use replication to publish the inputted data to a subscribing central site. One of the tables I wish to replicate has an identity column as primary key, but the records should otherwise be unique - i.e. no two records should differ only in the value of the key. Another table, which should also be replicated, uses this id value as a foreign key.
I can use the identity increment and seed to guarantee no key violations will occur when copying data to the central server. However, there is another issue: Several servers can create the same record but with different id values.
I need to "merge" such records by deleting duplicate entries in the table with the identifier as primary key, and update the foreign keys correspondingly. To clarify (I hope!), here's an example of what data I might have on the central site after copying data from two input sites:
TRANSACTION table
amount = 200, metadata_id = 1001 // Replicated from server INPUT_1
amount = -117, metadata_id = 2001 // Replicated from server INPUT_2
METADATA table:
id=1001 Actitiy=Sales, Country=USA
id=2001 Activity=Sales, Country=USA
What I would like is basically for the central site to identify that metadata 2001 is really the same as metadata 1001, update the foreign key in the TRANSACTION record accordingly and not import (or delete, if this "merging" is done in a post-treatment) the duplicate metadata record.
If anyone can offer any advice on how to achieve this I would appreciate your input.
Hello All,
I am using the Web Site Administration Tool with the ASP.NET login controls to create/manage user logins & roles for my site.
I have exported the ASPNETDB.MDF into my SQL Database ready to use with my app. The problem that I'm having is that whenever I add a user, using either the Web Site Administration Tool or the Classes available in the code-behind. The entry is doubled up in the database.
This is not a problem when logging on....however, when it comes to deleting a user it will only take one of the entries out and leave the duplicate in there. So if the administrator has deleted a user from the app and then tried to create another one with the same UserName (Which whomever is well within his/her rights to be able to do), they cannot because the entry which has "stay behind" in the database conflicts with the entry.
Any help on this matter would be greatly apprieciated. If any more info on this matter is required please ask (It was quite hard to try and explain this :-)
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,
Milfredo
