Sequence Clustering And Association Rules

Jul 13, 2006

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.

Association Rules

Dec 3, 2006

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.

Association Rules: Discretization

Aug 8, 2007

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

Association Rules Web Viewers

Jan 28, 2008

I 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?

Association Rules - Importance

Feb 14, 2008

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

y

n

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?

A Question About Association Rules

Jul 17, 2007

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!

The Data For Association Rules

Jun 20, 2007

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.

Usage Of Association Rules

Aug 15, 2006

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.

Best Regard

Association Rules Algorithm, Help?

Nov 22, 2007

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

Trouble Filtering Association Rules

Jan 7, 2008

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

Quick Question Regarding Association Rules...

May 28, 2007

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.

Prediction Query In MS Association Rules

May 22, 2006

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'

Creating A Taxonomy For Association Rules

Nov 23, 2007

Hello,

I would really appreciate if you could help me out. I am trying to create a taxonomy to be taken into account into the association rules algorithm. For example, if my data is a group of purchases from a supermarket I could have one client who bought milk, cookies and shampoo, and another who bough cheese, cookies and soap.

I would like to specify that milk and cheese belong to the category "dairy" and shampoo and soap belong to "personal hygene". If there are interesting rules regarding the categories I would like them to be taken into account. Additionally, I would not like to have rules like "milk -> dairy". If one specific object appers in a rule, its corresponding category should not.
In this scenario I could have milk and "personal hygene" in the same rule, but not shampoo and "personal hygene".

I have seen this done by other mining tools but I've been having trouble finding a way to make this possible in Analysis Services.

Thank you very much.

Association Rules Model For Problem

Aug 9, 2007

What would be the right design approach for the following problem?

I have a single table called SelectionFactors, which has the following columns and sample data:

ProjectID
Factor
FactorValue

1000
Countries
USA

1000
Countries
Canada

1000
Countries
France

1000
Languages
English

1000
Languages
French

1000
Company Type
Consulting

1000
Company Type
Software

2000
Countries
India

2000
Countries
China

2000
Countries
USA

2000
Languages
English

2000
Languages
Chinese (Simplified)

2000
Languages
Chinese (Traditional)

2000
Languages
Spanish

2000
Company Type
Retail

2000
Company Type
Dairy Products

The problem is to allow a descriptive analysis of the data to find patterns in the users selections. For instance,
if Languages->English is selected, what are the counts of projects for other Factor->Factor Value combinations?
Countries->USA = 2, Countries->Canada=1, Company Type->Consulting=1 and so on.

Since all the data is in this single table, are both the case and nested tables the same? What are the keys and inputs? I only need a descriptive analysis (no prediction) and ALL possible combinations MUST be part of the results; how should the model be designed?

Thank you,
Anna.

A Priori Algorithm In Association Rules

Question On Microsoft Association Rules

Jul 22, 2006

I build a data mining model to predict what are the best studying methods for the student to pass the examinaton.

Create Mining Model StudentAssociation (
Student_No long key,
Gender text discrete predict,
PassOrFail text discrete predict,
StudyMethod table predict ( MethodName text key )
) Using Microsoft_Association_Rules ( Minimum_Support=0.02, Minimum_Probability=0.03 )

The mining table will contain all the methods that the students use, no matter their examination is passed or failed.
The value of PassOrFail will have either 'Pass' or 'Fail'.

According to the above model, can I query the best studying methods?
Or I should only train the model with the student who pass the examination, and ignore all the failed.

Thanks.
Joe.

Association Prediction By Rules Still Returns Itemsets

May 22, 2007

If I use this code with an association model, it still returns itemsets for me - when it should be returning only nodes with rules associated with them (according to sqlserverdatamining.com). If I try adding 'AND $PROBABILITY > .25' to the where clause, it returns 0 results for every query I try. Any clue why this may be happening?

Code Snippet

SELECT FLATTENED
(SELECT * FROM PredictAssociation([Product],20,
INCLUDE_NODE_ID,INCLUDE_STATISTICS)
WHERE $NODEID<>'')
FROM
[ProductRecommend]
PREDICTION JOIN
OPENQUERY([ds],
'SELECT
[PRODUCTCLASSID],[DESCRIPTION]
FROM
[Product_Table]
WHERE
[PRODUCTCLASSID] = ''1234'' AND [DESCRIPTION] = ''DESC''
') AS t

ON
[ProductRecommend].[Product].[PRODUCTCLASSID] = t.[PRODUCTCLASSID] AND
[ProductRecommend].[Product].[DESCRIPTION] = t.[DESCRIPTION]

This query returns more relevant results than those lacking the filtering by $NODEID, however the results should have higher probabilities than .047! Please help! Thanks!

Association Rules Algorithm [support,confidence]

Dec 16, 2006

In assotiation rules each rule has a [support, confidence] part. In Microsoft Association Rules there is a [probability,importance] measure in each rule and importance can be greater that 1.

I found the following in msdn but i'm not sure if i understood correctly.

MINIMUM_PROBABILITY: Specifies the minimum probability that a rule is true. For example, setting this value to 0.5 specifies that no rule with less than fifty percent probability is generated.
The default is 0.4.

MAXIMUM_SUPPORT: Specifies the maximum number of cases in which an itemset can have support. If this value is less than 1, the value represents a percentage of the total cases. Values greater than 1 represent the absolute number of cases that can contain the itemset.
The default is 1.

My questions are
1) Can i explain the [probability,importance] in [support,confidence]? If yes, how?
2) What importance>1 means?

Thank you in advance.

Analysis Service 2005: Microsoft Association Rules Problem

Jul 11, 2007

Hi there,

i'm new to this forum .. Maybe my way of expression is not very good, but I hope to be understandable.

I've a sql server 2005 database with 90 columns and more or less 185 thousands records. I've to run microsoft associations rules on my laptop (sony vaio sz3, core 2 duo, 2gb ram).

The problems is that the amount of ram seems not to be enough [it starts to swap when it's reading 240th case)

Because of this, i decided to sample my data by extracting 10thousands records randomnly ... it lasts 25minutes (more or less) now, but it's still to much...

Does a better way exists? What's the problem: column or row numbers?

hope you guys can help me.

I need to use the cluster sequence approach; therefore I need to completely understand how it works. In order to understand it, I need to know which inputs it uses, how the algorithm works and which type of outputs does the approach throw. Do you have any idea where I can find this type of information? and examples?

Any help would be appreciated.

Sequence Clustering Model Processing Fails Due To Sort Order

Dec 18, 2007

I am using Sequence Clustering algorithm. (I've built several models with Clustering algorithm and Decision Trees for this client, which work fine.).

Background: Sequence data must be stored in a nested table, which can have only 1 non-key attribute.
I specify a mining model structure with the nested table key as the datetime, and the nested table discrete prediction column as [sort name] . this builds the model fine.

When I try to process this data mining model, I get Process failed: "Errors in the OLAP storage engine: The sort order specified for distinct count records is incorrect".

Iit may be that OLAP distinct count requests numerical data type, but not from the examples I've seen. Tried this anyway �� doesn��t work on numeric either �� same problem.
Any Suggestions?
