Continuous Variable Prediction
Sep 19, 2007
Hi All,
I was wondering if there was a way to specify a range when training a model to predict continuous variables. For instance, the predicted variable can only have a range of 1 - 10.
Thanks

Historic Prediction And Prediction Steps
Feb 22, 2008
Hi
After building a model in BI, I want to view the chart of model in mining model viewer, in the chart tab I can just see one prediction value that means for my model do prediction for some time slice and in prediction steps I can specify how many steps, I want to show this chart
In mining model viewer tab we can see the chart of prediction also decision tree and the chart is for showing all of value prediction, and with choosing prediction steps we can specify that show just one value prediction or two or several values. But sometime I can see just one value in chart and sometime I can see several values in chart,
This difference is for my data or no?
And also for viewing historic prediction I should choice €śshow historic prediction€? and before that I should set
Two parameters: Historic_ model _count and historic _model _count,
But I can€™t see historic prediction (sometime this happens)
Please help me.

i have to select records depending on @count parameter to this table.Depending on this parameter value it should fetch sequential dates.For example
if @count=2then result should be like this,

Continuous Merge Replication
Mar 7, 2008I am fairly new to SQL 2005 and have taken over a migration project from 2000 to 2005 and one of our scheduled jobs seem to run forever, but do not have errors. This did not happen in the past so I was wondering if the agent settings for Replication Merge has the -Continuous parameter will the job ever complete or does it really run "continuously"?

Predicting A Continuous Value (run Minutes)
Oct 23, 2007Hello,
I have a question regarding whether or not Data Mining can be utilized in a specific problem I have to solve.
Situation: I€™m going to simplify the problem by explaining it in terms of a €śpizza manufacturer€?. Suppose I wanted to predict the run minutes + downtime minutes (I use these to get an hourly rate: Pizzas/(run hrs + delay hrs) = Pizzas per hour) by looking at a set of input properties.
My properties could be something like the following:
# of Toppings
# of Special Pricing Stickers
Cardboard Box Indicator
Case Indicator (0 represents auto-casing, 1 represents putting in case by hand)
Machine Type (0 or 1€¦ 0 represents an older €“slower machine, 1 is newer)
Quantity of Run
(there could be up to 15 other properties that may or may not impact our rate)
Measured Values:
Run Minutes
Delay (down) minutes
Steps I€™ve Done So Far:
I€™ve created a couple different data mining models for this as I was unsure which one(s) to use. I checked the lift chart while feeding back in the original data set and my scatter plot appeared fairly inaccurate.
I've attempted to use Excel to create a linear regression, however my r squared value was always around .30. I decided to try to use SQL Server Data Mining to see if it could be something to help predict our accuracy better than a linear formula.
I've played with a couple different algorithms in Data Mining, and it appeared that none of them did exceptionally well with prediction. I even checked the lift chart using the same table as I used to train the model.
What algorithm(s) might work the best?
Can I reasonably expect a prediction within a fairly strict tolerance (I'm guessing the answer to this is: "yes, if your source data represents a consistent pattern")?
How can I best utilize Data Mining to give an answer like "historically, your run rate has been between these 2 values with a probability of X". I'm thinking I can utilize the predictprobability and stdev to some extent.
Any suggestions would be greatly appreciated.
If anyone needs further clarification, please let me know.
Thank you.

Dan
Continuous Attribute && Complexity_Penalty
Apr 27, 2007I am having one question about discretization of continous attributes
values. How does it work? I need this information for my thesis. I have a
continous attribut, namely SKS, with range 0-20. When I use Microsoft
Decision Tree algorithm, this attribut split in SKS <= 18 and SKS > 18. I
want to know how does it find 18 as a number to split not the other.
One question again about Microsoft Decision Tree algorithm, about
Complexity_Penalty parameter. How does it affect the algorithm? For example,
if I set this value=0.1 what does it mean and how does it correspond with
growth tree?
Thanks a lot before for your kindness to answer my questions.. :-)
Setting Up Continuous Trace File
Jan 29, 2002Does anyone know exactly how to create a trace that runs continuously on a server and writes the data to a table? Now I know how to create a trace file with the profiler, but I want something set up so that I don't have to have the profiler running on the server all the time. As well as soemthing that will restart itself if the server is rebooted. I have been looking at these x(xp_trace.*) procedures. Is this the way to do it?
I have to trap login information in a table and have a scheduled job that runs once a month and look for specific data in the table and send out e-mails based on certain values.
I have written the procedure which does this I just need to know how to set up the trace so it runs in the background continuously.
Can anyone help?
Thanks............

Continuous Data Pump Using SSIS
Mar 21, 2008Hi...My first post.
I'm currently creating a SSIS package that takes data from 3 unique databases. A SQL DB, FoxPro DB, and an Oracle DB. The data is pulled, cleansed and put into a single SQL 2005 table. The data is then pulled from this table every 15 minutes, formated in a given specification and uploaded to an ftp site. This part is done. My question is this:
This package needs to run around the clock, non-stop. How can package be set up to do this? It needs to pull data from the 3 DBs and put it in the common table, wait 15 minutes and do it again. Wait 15 more mintues and do it again. And so forth. A problem I'm having is I don't see a way to set up a SSIS package so that it runs around the clock.
On same premise, I have another issue. When I try to take data from the common table and there is nothing there, it causes an error. Is there some way that you can run a test like
SELECT * FROM _table_ WHERE is_sent = 0
if results == 0
{
wait 15 minutes and test again.
}
else if
{
write flat file, wait 15 minutes.
}
This has to be done in the Control Flow scope, so I can't use a conditional split. This is a pretty big deal as this needs to run around the clock. Thank you in advance for your assistance.
Need Help Keeping Continuous IDs Using Merge Replication
Apr 11, 2007I was wondering if anybody knows how to solve this problem. Here's the setup.
There is an ASP.NET application running on a local web server at the customer's location, it currently uses a MSDE backend database. There is a copy of the application on the customer's webhosting company so it can be accessed from outside the customer's location it is running on a full version of SQL Server 2000. We have this setup because the customer's ISP is not very reliable and the customer needs to be able to use the application even when their web connection is down. It is also used from outside their location by sales people and management and remote offices. The problem is we want to keep both databases synchronized together. We had been using Merge Replication which was working fine until the local ID jumped because it had run out of allocated identities. This causes a problem for their accounting because now there is a gap in the document's numbers.
Is there a way to have the identity field (or a generated document number) to remain continuous and unique across both databases? This needs to also work if one of the databases were to go down for a time or lose connectivity between the two servers. I'm looking for any option. We also have the option of upgrading the application to SQL Server 2005 if needed. Any ideas are appreciated.
Thanks,
Seth
Continuous Merge Replication - Event Log
Aug 22, 2006Hi
I have set up merge replication and it works nicely.
I have set it up to work continuously, because I thought that if it can't find the subscriber or is offline then that's fine it will just sync again when it's back on line.
This is true
BUT it keeps throwing lots of messages into the event log to tell me the merge has failed.
SO
a. Can i just turn off the error reporting
or
b. How can I get it to sync this way automatically on connection without the error messages
thanks

Continuous Nonstop Pumping Of Data
Mar 4, 2007I have one data pump in a series that was pumping in too many records. Doing an independent query of the source table, I found there was about 140,000 records. My pump uses a variable for the source query, nothing fancy just a simple SELECT * FROM table WHERE DateField > '4/6/2006 12:00:00AM'. The Destination is local on the SQL Server and is set by a variable, and does a fast load. When I went away and checked in BIDS while it was running (the data flow tab where you can see the record count) it was at 28,000,000 and still going!
Any ideas what could be causing this? As I say there are only 140,000 records and no joins in the query--is this a bug someone has run into before?
Thanks,
Kayda
Continuous Predictable Problem In MDT Model
Dec 18, 2007It seems i face a problem with the Microsoft Decision Trees model when i have a predictable variable that is continuous.
I have created the whole model according to the AdventureWorks tutorial (and it informs me that the same procedure is followed with a continuous variable) and i have flagged the variable as continuous. Even though everything seems be going well, the results i get are not correct (after a cross check with another project already done and checked).
Is there something i am missing or i skipped while creating the model? Any suggestions that may help me are appreciated
Thank you in advance

Strange: Continuous Login Failure Errors
Jun 5, 2007I have SQL 2000 Server that had a database called ABC and it has been moved to another server on 5-15-2007
I kept ABC database in Read_only mode for few days (just in case) on old server and finally dropped it on 5-20-2007 and I think I forgot to drop the associated logins. I started seeing login failure for user 'xyz' in error logs
When I first noticed the login failure error in SQL Server log for login xyz, I deleted xyz login but it did not stop the errors.
I have been trying from then and no luck in identifying the cause/ resolving this issue.
I have ran SQL profiler trace and caught the user hostnames, NTusername in few cases and Application Name and contacted the Application owner & user (who are in the trace) to stop windows service/ schedule jobs..anything that is pointing to old server but the bad luck is they are not aware of anything running or pointing to old server. The worst part is the user whose hostnames are shown in the trace have never used ABC database and do not have any idea.
Here is what I found in the profiler trace:
TextData LoginName NTUserName HostName ApplicationName
Login failed for user 'xyz' xyz AB00007 WAB000007 Microsoft (r) Windows Script Host
Today I have created the xyz login in the server and assigned model database with reader permission to see if log some different error but nothing new (the same login failure error)
Finally, I had no solution other than restoring the ABC database back to my old server and set it in to Read_Only mode to stop these errors and Now I see the login 'xyz' firing the query against the database
* Any hint or pointers why this is happening and any possible solution on this?
How Handle Continuous Until Cancelled Date Field?
Aug 9, 2006We have a table in our legacy database system representing health insurance polices. The customer can, and usually does, renew the policy after 12 months. The legacy database uses the renewal string "99/99/9999" to signify "continuous until cancelled", in other words, "forever", or until cancelled
We need to convert this legacy table into a sql 2005 table, which supports the concept of "forever". But how can we do this? ("99/99/999" is not a valid sql date type and we don't want to use varchar for dates.)
TIA,

Prediction Accuracy
Mar 5, 2007Hi ,
I am a novice Data Mining Programmer.
I am using Time series algorithm for forecasting.
We are Quite concerned about the accuracy of Prediction output.
For Example Our Data is like this
StudId Date Perf
001 01/01/2001 90
001 02/01/2001 89
001 03/01/2001 87
002 01/01/2001 59
002 02/01/2001 70
003 03/01/2001 47
If I write my Prediction Query to predict for 100 th time step.Its giving me out put like
Date Perf
03/01/2015 47.000000115
We are not sure about the accuracy of the values. Is it possible to use trend information as input to my model and make my prediction based on that.
I don€™t know how to do that? Can anyone help?

Multicolumns Prediction
May 6, 2007Hello,
Here's the thing base on AdvantrueWorks: case - orders, nested - products.
I'd like to select-predict models and their identifiers.
So, I added new id column to the relational view.
And then I added the column to the nested table in my structure as predict only.
The problem - all predictions changed dramatically.
For example when I run my query again:
SELECT PREDICT([Association].[Products], 5)
From [Association]
NATURAL PREDICTION JOIN
(SELECT (SELECT 'Touring Tire Tube' AS [Model]) AS [Products]) AS t
I got the new column i added, but the results are far different then before (and incorrect).
Is there a easy way to workaround it?

Prediction In Ms Sql Server 2005
Jul 13, 2006Hey
Does anyone know if the following is possible:
I want to add a column to a table that contains the predicted value according to a decision tree mining model. (I know that this is possible). But now I would like that when a new row is added to this table, and every column except the prediction column is filled in manually, can ms sql server add the predicted value automatically for this row?
I know it is possible to execute a Singleton query for this kind of single prediction, but I would like to integrate this in my data table, because for now my steps would be:
- Create the table with one prediction column
- Add the known values of all columns for one row
- Use singleton query in Mining model prediction tab to know the predicted value
- Fill in the predicted value manually in my table.
I hope my question is clear.
Thanks in advance for the help.
