Error In Prediction Query
Aug 19, 2006
Hi,
I have the following
association model Structure
Where I am trying to find out
the associations between various service activities so that when a customer
buys a service activity we can recommend him/her others
CaseTable
CustomerId Ă Key
IncidentId
Nested Table
ServiceId Ă Key
ServiceName Ă Input, Predict
IncidentId Ă Link to the case table
Firstly is the above
structure correct??
Secondly
I have the following prediction
query
SELECT
t.[ServiceId],
Predict
([ServicerossSell].[ServiceCross-SellRecommend],3)
From
[ServicerossSell]
PREDICTION JOIN
SHAPE
{OPENQUERY([Adventure
Works Cycle MSCRM],
'SELECT DISTINCT ServiceId
FROM Service ORDER BY ServiceId]')
}
APPEND
( {OPENQUERY([Adventure Works Cycle MSCRM],
'SELECT DISTINCT ServiceId
FROM Service ORDER BY ServiceId]')
}
RELATE
[ServiceId] To [ServiceId]
)
AS
[Service]
AS t
ON
[ServicerossSell].[ ServiceCross-SellRecommend].[ServiceId]
= t.[Service].[ServiceId]
It throws the following error
€śThe DMX column was not found in the context€?
I am not able to figure out why, any help would be most
appretaiated

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.

Hi!
I'm building a mining model wiht MS Association Rules. After processing this model, the result includes some rules(example):
E = Existing, C = Existing -> B = Existing
F = Existing -> E = Existing
C = Existing, B = Existing -> E = Existing
F = Existing -> B = Existing
B = Existing, A = Existing -> C = Existing
F = Existing, B = Existing -> E = Existing
F = Existing, E = Existing -> B = Existing
D = Existing -> A = Existing
C = Existing -> A = Existing
E = Existing, A = Existing -> B = Existing
I want to buid a query that has two or more items on the left of the rules, example: E = Existing, C = Existing -> B = Existing
->I want to buid a query to predict that: when a customer buy 'E' and 'C' then he likely buys 'B'

hi,
Is it possible to use two algorithms together?I need to write prediction Query so that its should both models having clustereing algorithm and timeseries algorithm.
for example
I am having student information.I ve to predict performance of students for certain period.The students should be classified by their types like rich kids,poorkids..like that.I need to predict the performance of the rich kids??

Dear friends,
I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3).
I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining.
WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder
- select case table -> Homeowners
- Drag the Customer ID column from the Homeowners table and drop it on the grid
- Drag the BEDROOMS column from the mining model and drop it on the grid.
- On the last row: Source=PredictionFunction, Field=PredictProbability
- Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument
- Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN?
WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
Thanx a lot in advance, please help me!

I am doing this right now this way:
1) I do the DMX prediction query where I get the PredictNodeId(predict_var), my query is like this:
SELECT PredictNodeId(predict_var), model_1.predict_var, t.var_1, t.var_2 FROM model_1 PREDICTION JOIN OPENQUERY([DATA_SOURCE_1], 'SELECT var_1, var_2 FROM table_1') AS t ON model_1.var_1 = t.var_1 AND model_1.var_2 = t.var_2
2)I do the DMX query to get the node_description from the model.content iterating each row from the result of my prediction query, this query is like this:
SELECT node_description FROM model_1.content WHERE node_name = 'node_name_var'
In this query node_name_var = PredictNodeId(predict_var) from my prediction query.
What I want to know if there is a way to merge Query 1 and Query 2 so I can get the node_description in the same query qhere I get the PredictNodeId.
Thanks

Hi,
Can i use a CASE statement in a prediction query.
the following query is throwing me an error
SELECT
CASE [Sales Forecast Time Series].[City Code]
when 'LA' then 'Los Angeles'
WHEN 'CA' THEN 'California'
ELSE 'OTHERS'
END,
PredictTimeSeries([Sales Forecast Time Series].[Sales Value],5)
From
[Sales Forecast Time Series]
ERROR:
Parser: The statement dialect could not be resolved due to ambiguity.
Also
Is it possible to discretize the
Sales Value column using a the CASE statement, the output column of
PredictTimeSeries function.
Is there a link that can give me a
comprehensive info on what can be achieved and what cant be using DMX queries

I have a question about what is possible with a prediction query
against a nested table. Say I have a basic customer-product case and nested table mining model like so:
Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[Products] Predict
(
[ProductName] ,
[Quantity]
)
)
Using Microsoft_Decision_Trees
I can write a query to find the probability of product (and quantity) A like so:
SELECT (select * from Predict(Products,INCLUDE_STATISTICS)
where ProductName = 'A' )
FROM DT_CustProd
NATURAL PREDICTION JOIN
(SELECT 'M' AS [Gender],
27 AS [AGE] ) AS t
What if I know that the query customer (M,27) in question has purchased product B, how can I use that in the prediction join to predict product A? The fact that product B was purchased might influence the prediction, right?

I have a question about writing a prediction query against a clustering model that has the same column added more than once.
Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look? If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query?

I believe saving prediction query results to relational tables is possible (the BI studio does it!). I am not clear on how to do this w/o the BI studio, which means if I write a DMX query and want to store its output to a relational table, how do I do it?
Tips, anyone?

Hi
I have three questions about several topics.
In this code:
public string ConnectionString
{
get
{
return "Provider=MSOLAP.3;Data Source=localhost;Initial Catalog=Adventure Works DW";
}
}
What is data source and initial catalog and what does this code do? And if I want to use other database how can change this code? (This code is for data mining viewer client project)
And in this code:
SqlConnection cn = new SqlConnection("Data Source=localhost;Initial Catalog=AdventureWorks;Integrated Security=True");
SqlCommand cm = new SqlCommand("Select AddressID,AddressLine1 from Person.Address", cn);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cm;
DataTable dt = new DataTable();
da.Fill(dt);
this.comboBox1.DisplayMember = "AddressLine1";
this.comboBox1.ValueMember = "AddressID";
this.comboBox1.DataSource = dt;
what is comboBox1.DisplayMember and comboBox1.ValueMember ,and what is difference between those ?
and other question:
in adventure works dw project for data mining predicting ,in forecasting model ,if I want to show the result of this query in the combobox in c# how can I show that?
SELECT
PredictTimeSeries(amount)
From
[Forecasting]
And again in this code ,it has a result which has two culomns ,on of them is for amount and other column is for time ,in sql I can save this result in exsiting table or neew table with wizard,but I want to
Do this work in c#,that€™s mean with a adomdconnection I connect to forecasting model and write this query then in a datagridviwe ,Iwant to see the values of prediction in adventure works dw database.

Hi ,
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?
Thanks,
Karthik.

Hello,
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?

Hey
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.

I have a market basket model using associations. It generated several dozen itemsets. However when I attempt to run a singleton prediction like this:
select (Predict(Orderproduct3q,INCLUDE_STATISTICS,10)) as [Recommendation]
From
[Case All]
NATURAL PREDICTION JOIN
(SELECT (SELECT '16407' AS [Pname])) AS t1
the resulting predictions don't take the itemsets into account. Instead, the predictions consist of the ranked products in the training set, ordered by frequency. This appears to happen regardless of the precise query specified within the "natural prediction join".
What's going on here and how do I generate a singleton prediction which makes use of the itemsets?

If your prediction join is to a SQL datasource, you can easily write a SQL query which returns a nested table like:
SELECT
Predict([Subcategories],2) as [Subcategories]
FROM
[SubcategoryAssociations]
NATURAL PREDICTION JOIN
(SELECT
(SELECT 'Road Bikes' AS Subcategory
UNION SELECT 'Jerseys' AS Subcategory
) AS Subcategories
) AS t
What about if your datasource is a cube? Is there some special MDX syntax similar to the SQL syntax above? Or do you have to utilize the SHAPE/APPEND syntax as follows?
SELECT t.*, $Cluster as ClusterName
FROM [MyModel]
PREDICTION JOIN
SHAPE {
select [Measures].[My Measure] on 0,
[My Dimension].[My Attribute].[My Attribute].Members on 1
from MyCube
}
APPEND (
{
select [Measures].[Another Measure] on 0,
NON EMPTY [My Dimension].[My Attribute].[My Attribute].Members
*[Product].[Product].[Product].Members on 1
from MyCube
}
RELATE [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
TO [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
)
AS [My Nested Table] AS t
ON [MyModel].[Product].[Product] = t.[My Nested Table].[[Product]].[Product]].[Product]].[MEMBER_CAPTION]]]

Is there a way to display the actual predicted value for an output attribute for a particular model. For example, say I am trying to predict if a particular customer is going to take advantage of a promotion (0=no, 1=yes) and I use neural networks. I know that I can use "Predict" to give me the prediction "yes" or "no" for each customer. However, the neural network actually spits out a number as a result. For example, a 0.997 would be interpreted as a "yes" for life insurance promotion. I do not want the probability that the prediction is correct. I want the actual output for the network.
The reason being is that I want to compute an error rate between the predicted value and the acutal value (root mean squared error or some other measure). Is there a way to compute this using the mining model prediction tab design view? I do not want to write the actual query as I teach a course in data mining using SQL Server and my students do not know DMX queries.
Thanks for any help you can provide.

SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).
