Hello Developers,
I used the add mining model to mining structure to modify a model so that maximum itemset =2, min prob=.01, min support= 2.
When i select maximum rows to anything higher than 2000 (default) i get duplicate rules.
The maximum rules returns is exactly16000 even though i set it higher than that.
Any ideas on the causes?
Thanks
Davy

Hello all,I know that this is a long shot, but I have a problem which someonereading this group *may* just be able to shed some light on.We have a new internal personnel planner/attendance system in place. Ituses a web interface to allow members of staff to select their sitelocation for any week, request leave and record absences.The server-side scripting is composed of VB/ASP and Javascript whichultimately queries & writes to an MS SQL Server 2000 database via anODBC connection between webserver (IIS6.0).Here is the problem and I *know* that it sounds unlikely/impossible butwe carried out exhaustive tests.-> I open a web browser on my local PC (XP Pro SP2)-> Login to the web-based planning system-> Update information-> Submit ChangesAt this point I get a script error:---error message---Microsoft OLE DB Provider for ODBC Drivers error '80040e14'[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntaxnear ')'./staff/wfp/Whereabouts/writeAbsence_v2_5.asp, line 108-------------------Which is fair enough as it probably points to a problem with the SQLstatement being passed by the .asp page.***BUT*** I _only_ get this message when I access the page via a browserfrom certain PCs!I have tried 3 browsers: MSIE6, Firefox1.5, Opera8.5.I have obviously ensured that it isn't any kind of browser caching issue.I have no issues using scripted-based web pages in general from the PCin question.I have checked the regional settings to ensure that I am using astandard character set.I *can* submit database changes via web browsers from most other PCs onour network, without incurring the error message.Even when I get the error message, the values are written to the db andthe information is updated.The other PCs from which I am experiencing the same difficulty areservers running Win2000 & Win2003 respectively.Is there any kind of OS/User Profile setting which would mean thatscripts running on a remote webserver would fall over when trying toperform an SQL write?Could it be some kind of character encoding issue, which means that theparameters that are received by the .asp script and then written via theSQL statement are mangled in any way?I can't see that there is any kind of local setting that would influencewhether remote scripts would or would not cause an error such as this.If anyone has any ideas, has encountered anything similar or can shedlight on a system-specific setting or feature that may cause this,please post your thoughts.Yours GratefullyGuy

Hello,
Let€™s say (for simplicity), in my site you can do one of two things €“ look at products and buy products.
I want to build an association structure between my products based on those two actions, but(!) when a user looks at two products it creates less important association than when the user actually bought those two products.
So basically, I want to give a different factor base on different actions occurred on my products.
How do I build my structure? How do I query it?
I'm trying to figure out how to build a personalization engine.
If my structure is built with users as case, and products as nested - I€™d like to predict best products per user (rather than associated products), and If possible, ignoring products he already bought.
How do I do it?
Hi,
I am working on a table that has following fields transaction_id, product_name,product_brand,product_size,product_quantity.
fyi, If a customer purchases 3 items, all have same transaction_id.
I need to use this table (in BIDS) for finding associations between different products,, but I am unable to do so.
Can anyone help me as to which fields should be used as input so that I can predict the association.
Thanks a lot.

When i use the MS association rules ,i don't know how it is worked on the background .I stuy the Fp-Growth algorithm , but there're some questions , I don't kown what's the meaning of transcation database. who can give me one example ? thanks .I know we can store the data in relation database,but in basket Analysis ,how a transaction stroed in relation database?

Hi,
I have a product basket scenario in where I have to recommend contracts to a customer based on the product and the quantity he/she buys. Product Quantity is an important factor which administers the user in the purchase of a particular contract
I have the following tables with me.
Customer product transaction table, Customer Contract transaction table but there is no direct relationship between contract and product in the database. The only way the two can be linked is through the customer.
If I create a mining structure with Customer-Product information as the nested table and Customer-Contract information as the nested table with customer being the link between the two, the model is showing some irreverent contract recommendations.
what is the solution for the above problem? Is it because the is no direct relationship between the product and the contract?
How can I overcome this problem?
1) I use the identifier of transaction and attribute in one table.
Do I can to build a association rules structure without the use of the nested tables?
I tried - did not turn out...
2) As it is necessary to use a main and child table, can not build a prediction query.
When I try to add the predict column in a criteria/argument (Field=PredictSupport), i'll given message:
"Nested table column cannot be used as an argument in a data mining function."
I can not use other columns, because they are not predicable.
I'm wondering if anyone can give me some help with an association model I'd like to setup. It's a typical market-basket analysis, but rather than grouping by individual customers, I'd like to group by customer grouping. (In our database, customers are grouped into categories like: large, small, medium) If this is possible, I'd like to generate the most popular items (so just querying the most probable itemsets), for each customer grouping (I'll refer to this as 'segments' from here on out), and then create a listing of customers in each segment which do not have the most popular items for their segment. I know for this last part I can use reporting services to tackle that problem, however, I'm not really sure how I can really do the rest of this with an association model in SSAS.
Our table structure looks like this:
Code Snippet
CustomerTable PurchasesTable
------------- --------------
CustomerName(key) CustomerName
CustomerGroup PurchasedProduct
And the data is arranged in this fashion:
Code SnippetCustomer Table:
CustomerName CustomerGroup
------------- -------------
A large
B large
C small
Purchases Table:
CustomerName PurchasedProduct
------------ ----------------
A ProductA
A ProductB
B ProductA
C ProductC

Hi there,
it has been a long i'm trying to execute Microsoft Association Rules on my database.
I solved memory leak problem now, but i still can't understand output rules.
Database contain all the italian student who took a degree last year. Here in Italy, they have to compile a summary where they speak about universitary experience. ie: they talk about experience with teachers (pointage from 1 to 5); they says if they want to continue in the universitary field or not, and so on.
Most of the rules, says:
Int_Stud=1-2, RapDoc>4
Int_Stud is the column where i store student intention to continue university. 1 means they want to go on, 2 means they do not want to continue to study. So, this rules has no sense, because it relates all the student (in my mind): the one who wants to continue university and the one who do not want to.
I think problem is that visual studio 2005 and analysis service has no understanding of Int_Stud world, they've no idea that Int_Stud can have just 2 values and that they're opposite each other. Is there a solution to this problem? Can i discretize this column?
Even if I know not to have perfect english, I hope to be understandable
What is the algorithm that generates the itemsets in the Association model? I'm looking to possibly use this part of the Association algorithm (i.e. the grouping into itemsets) in a separate plug-in algorithm.
View 1 Replies View RelatedWhy do association itemsets have probabilities associated with them when its rules that generate probabilities? Any queries I do against my model are using these itemset probabilities rather than the probabilities that the rules generate. More over, the probabilities generated for these itemsets are far less than the MINIMUM_PROBABILITY tag in the algorithm properties menu.
View 3 Replies View RelatedI note that there exist three web viewers for data mining algorithms, namely, DMNaiveBayesViewer, DMDecisionTreeViewer and DMClusterViewer. How come there are no viewers for association rules (itemsets, rules, dependency network)? Can you suggest any alternative way of showing such valuable information in a web application?
View 1 Replies View RelatedHello,
How do I get n and only items predicted by a specific item(s) either directly or indirectly as shown in the dependency network diagram?
For instance, the predict function won€™t work for me - because running this query on AdvantureWorks:
SELECT PREDICT([Association].[Products], 5)
From [Association]
NATURAL PREDICTION JOIN
(SELECT (SELECT 'Touring Tire Tube' AS [Model]) AS [Products]) AS t
Returns Sport-100 as a second result, although it is not predicted by any mean by Touring Tire Tube as shown in the dependency network diagram.
My query should have returned just one row - Touring Tire.
I understand Mr. MacLennan's explanation provided at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=282651&SiteID=1 and appreciate the time he took to explain how importance works. However, like the user with username "sang", I also ran the data in BI 2005 and got the same results listed by the aforementioned user. I did this using the following data:
donut
muffin

etc.
The rule muffin -> donut has an importance of -0.105302438, which is not the same as Mr. MacLennan's results. I tried switching the roles of a and b in a -> b and using different bases on the logarithms. I don't get the result of -0.105302438 with any of these. I also tried to calculate importance with a small data set I have and can't get the results using Mr. MacLennan's explanation with that data set either. Any thoughts on the descrepancy?

Hi
I am doing the Market basket analysis for a retailer using association rule. The whole data set is huge which contains grocery, clothes and books etc. If I want to check out the relationship between several different clothes brands, (e.g. LEVI'S and adidas), should I just remove all the grocery and books transactions, use the subset which only contains clothes transactions to re-run the association rules? Is this gonna work?
Thanks in advance!
Hi
I got a question about the data preparation of market basket analysis.
There are always some transactions with only one single SKU product. It seems that these kind of transactions have nothing to do with association. Shall I just exclude them or what?
Thanks in advance.
hi,
i have a exercise using association datamining
my database have 350 records,
i use 90 records for datamining and it release some rules which i choose on top of mSOLAP_NODE_SCORE,
but when i use select statement to check my result i have 1 records, the same as my result, and 5 records not true;
for example:
rules A=a,B=b-> C=c
select * from <my_table> where A='a' and B='b' and C='c'; ==>1 record return
select * from <my_table> where A='a' and B='b' and C<>'c'; ==>5 records return
C with 3 values c1,c2,c
with the second statement C includes 2 c1 and 3 c2
i don't understand how they work.
i want to choose some best rules can present my database.
how can i choose importance and probability to get best rules.
with database have 90 records and a database have 350 records which values i should use for minimum_probability, Minimum_Support, Minimum_importance...
when i choose rules i should choose on importance or probability.
thanks for your help
Hello,
I want to score my data by only the assoziation rules I filtered in Mining-Model-Viewer.
Is this possible?
I recognized that MiningModel Predictionquery uses the generated Model (all rules).
Is there any way to influence the model at generating time.
Thanks a lot.
Hi,
I specified the point to solve my problem but I did not understand why MS SQL Server didn't recognize the Association parameters I but in. It uses the Minimum_Probability I put in, but the Minimum_Importance i wrote didn't care it, it use the default value.
I want to paste a screenshot here but it isn't possible. By the way I'm using the evaluation version, which should be same as the enterprise edition.
Hope for a soon answer.

I need to create a set of cases for a project that uses the Microsoft Association Rules algorithm to make recommendations for products to customers. My question is: the set of scenarios must include all transactions of customers for training?. or is it sufficient some percentage of total transactions? If i do not use all transactions of customers, could be that the algorithm does not consider some products in their groups or rules and could not make recommendations about these?
thanx

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?
I've set up an association rules mining model on SQL Server 2005.
Below is the output for the "rules" tab in the model viewer:
0.457 0.480925197502775 BAKERS BASKET = Existing -> FR ORANGE JUICE = Existing
0.423 0.467835626151174 ONE EGG = Existing -> FR ORANGE JUICE = Existing
0.416 0.42489020548496 GRANOLA PARFAIT = Existing -> FR ORANGE JUICE = Existing
0.416 0.344523279228151 CROISSANT = Existing -> REG CAPPUCCINO = Existing
0.430 0.338244068974039 PAIN AU CHOC = Existing -> REG CAPPUCCINO = Existing
0.424 0.332652863071932 FR ORANGE JUICE = Existing, REG LATTE = Existing -> REG CAPPUCCINO = Existing
The problem is that I can't seem to reduce the minimum probability below .42 to view more rules.
I've considered that it might be becuase these are the only rules discovered, however I know quite a bit about the data and I would excpect many more associations.
The data is transactional in the format
TransactionID, ItemID
Hello,
I'm new to analysis services and hopefully this is a quick & easy question. I have a couple of quite large (163,000 tuple) tables with columns essentially representing a bit vector. I would like to mine for association rules but the number of '1' values are very, very sparse and they are the only objects of interest. How can I get more control over the algorithm---that is, how can I stipulate that the state of the column must be '1' to be considered? Any help or direction to the proper documentation would be great.
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
I read the paper of sequence clustering. It seems that the major application of the algorithm is for the web site. I was just thinking that can I apply this algorithm on the purchase sequences of credit card data?
If so,please also tell me the difference between sequence clustering and association rules on credit card data application. Although I realize that sequence clustering is a fully probabilistic model and it has the capability of prediction, association rules also give the probabilities of purchasing the other products.
Thanks in advance.

Hi
I am working on an academic medical project. I have created PATIENT table
PATIENT_ID
NAME |
CITY
DISEASE table
DISEASE_ID
NAME |
and Relationship table[FOREIGN KEYS]PATIENT_DISEASE
PATIENT_ID
DISEASE_ID
I am using Microsoft association algorithm [SQL Server 2005 BI Studio] to find association between PATIENT CITY --> Associated DISEASE. I will be entering dummy data into these tables as this is academic project. I like to know can i be able to find the associated Disease/s with the PATIENT City with this algorithm ? such a way as soon as the user enters PATIENT City, assocaited Disease will be selected from the diseases table? on web interface [asp.net].
i like to know after building this association model, can i use it on my web page to prompt the user associated disease with patient city? or building this model only gives association rules, i need to write a procedure or t-sql statements to implement the association rules?
I am using SQLSERVERDATAMINING.COM tutorials to build the model.
Your information and help is highly appreciated.
