How To Predict?
Mar 30, 2007
I have a question.The question is to predict what to do next.
I have a table with three columns.
CustomerID ServiceContent ServicesID
140105100001 Service1 1
140105100001 Service2 1
140105100001 Service3 1
140105100001 Service1 2
140105100001 Service5 2
... ... ...
I want to use SQL Server 2005 Data Mining to predict what services that one customer will accept next.
Thanks

i have table:
customer(customerid, age,sex....)
orderdata(orderid, customerid,day)
orderdetails(orderid, productid, quantity)
products(productid, productname,...)
now, i want to show some product for customer when i now him age and sex.
e.ct: if he is a man and age =20 i show product : ball, pull, sport close....... if man is a woman , i show lips, babara, t_shirt, skirt....
if man is a chirdren, i will show joy, story for chidren....
how i create my mining model. and how i query for result in DTS

Hello,
I installed the bike buyer example and i am learning the DMX language. Now i wrote the following query (using MS decision trees):
SELECT
T.[Last Name],
[Bike Buyer],
PredictProbability(Predict([Bike Buyer])) AS [Probability]
From
[v Target Mail]
PREDICTION JOIN
OPENQUERY
(....... And so on..)
Now the result is surprising to me. In the resulttabel all the probabilities are equal.
Bike Buyer Probability
1 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
0 0.99994590500919611
1 0.99994590500919611
and so on.
Now i am wondering what predictProbability means. I thought that PredictProbability meant the probability that the prediction is correct. Now all the probabilities are the same and the input is different. Can somebody tell me what PredictProbability means or am I using it wrong?
Thanx in advance,
Joris Valkonet

Hello,
Can someone please assist?
I have no problem using the provided Algorithms (NaiveBayes, Decision Tree, etc) from SQL Server 2005 Data Mining. For example: If I want to predict whether the customers want to buy bike from the following data, then I use Age, Salary, Gender as input/attribute/feature selection and BuyBike column as "Predict" column.
Table
Age Salary Gender BuyBike
------------------------------------
However, say that I have 10,000 types of bikes to predict. How to do that?
Age Salary Gender BuyBike1 BuyBike2 BuyBike3 ...... BuyBike10000
------------------------------------------------------------------------------------
Are there any online resources discussing this issue? I am desperately try to solve this problem. Please assist!
Mary

how i do in data mining to predict that products ?
more: i want know how much percent of product is like by buyer
or i want show products with desc % of the like of people

Generally, what would be a good start to model and make predictions based on the following.
Even Dollar Transactions €“ Including transactions that end in $0 or $50 with a Total Transaction Amount between $400 and $5000.
I have a table called Transaction with a BillingAmount column.
I've gone through the SQL Server 2005 Data Mining Tutorial (which uses a discrete prediction BikeBuyer yes or no) and read a lot of Data Mining with SQL Server 2005. Neither of these give good, complete, methodical examples of selecting inputs and targets and making predictions; especially for continuous columns.
I think I'm generally struggling with the concepts of selecting (continuous?) predictable attributes and calculating predictions based on the results. Are there any examples of a scenario similar to the above that I can reference? or just some advise.

I want to query my msdb job and jobschedule related tables to generate a list of runtimes for each of these jobs for the next day or any future date. This query should output JobID, Run_Date(YYYYMMDD), and Run_Time(HHMMSS).
If I have 3 jobs with...
Job#1 scheduled to run once every 4 hours between 6 AM and 10 PM
Job# 2 scheduled to run every 15 minutes between 11 AM and 1 PM
Job# 3 scheduled to run every minute between 4 PM and 4:15 PM
my output should look as below ....

Hi,
I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:
Executing the query ...
Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader
COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object..
Execution complete
I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file)
So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.
As I said it is not a very descriptive message but I hope I have hit a general issue.
Thanks...

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.
