Question On Attributes Selection For Un-supervised Algorithms And Supervised Algorithms
Jul 19, 2007
Hi, all,
Thanks for your kind attention.
Just wonder is there any good idea for us to select attributes for training models? Both for non-supervised algorithms like Association Rules and Clustering etc. and supervised algorithms like decision tree etc.
It will be much interesting to hear from you for any best practices and popular methods of dealing with this issue.
I am looking forward to hearing from you and thanks for your advices.
With best regards,
Yours sincerely,

Here is how you get the check digit for EAN-8, EAN-13 and EAN-14.CREATE FUNCTION dbo.fnGetEAN
(
@EAN VARCHAR(13)
)
RETURNS VARCHAR(14)
AS
BEGIN
DECLARE@Index TINYINT,
@Multiplier TINYINT,
@Sum TINYINT
SELECT@Index = LEN(@EAN),
@Multiplier = 3,
@Sum = 0
WHILE @Index > 0
SELECT@Sum = @Sum + @Multiplier * CAST(SUBSTRING(@EAN, @Index, 1) AS TINYINT),
@Multiplier = 4 - @Multiplier,
@Index = @Index - 1
RETURNCASE @Sum % 10
WHEN 0 THEN @EAN + '0'
ELSE @EAN + CAST(10 - @Sum % 10 AS CHAR(1))
END

I am in the stage of design for an application that uses SQL server 2005. We intended to encrypt some sensitve data using the encryption features in SQL server 2005. we will use symmetric key encryption. The question here is which symmetric encryption algorithm has the best performance? how much does the key size affect the perfromance? the data to be encrypted will be some lines of text equal to a word document.
any ideas?

Hi All,
We're currently preparing for a project for a bank client of ours where we would be using SQL Server 2008's data mining capabilities.
In the context of the out-of-the-box algorithms of SQL08 does the algorithms Logistics, Clustering and Logistic Regression includes Dynamic Logistics, Dynamic Clustering and Dynamic Logistic Regression?

Hello Everyone,
I am reading DataMining Tutorial and right now I am at the Mining Algorithms section. I cannot understand any of the algorithms. For example take the following text... what a bunch of mouthful bla bla bla it is ....
"The Microsoft Decision Trees algorithm supports both classification and regression and it works well for predictive modeling. Using the algorithm, you can predict both discrete and continuous attributes.
In building a model, the algorithm examines how each input attribute in the dataset affects the result of the predicted attribute, and then it uses the input attributes with the strongest relationship to create a series of splits, called nodes. As new nodes are added to the model, a tree structure begins to form. The top node of the tree describes the breakdown of the predicted attribute over the overall population. Each additional node is created based on the distribution of states of the predicted attribute as compared to the input attributes. If an input attribute is seen to cause the predicted attribute to favor one state over another, a new node is added to the model. The model continues to grow until none of the remaining attributes create a split that provides an improved prediction over the existing node. The model seeks to find a combination of attributes and their states that creates a disproportionate distribution of states in the predicted attribute, therefore allowing you to predict the outcome of the predicted attribute"
In the above text what is meant by discrete and continious attributes? what is regression? what is predicted attributes? what are input attributes? what is distribution of states?
Is there a source which explains these algorighms in a easier way ....

Hi,
In the info for SQL Compact Edition 3.5 it states that one of the features is:
Support for newer and more secure encryption algorithms.
I can't seem to find details of exactly what these new, more secure algorithms are. It appears 3.1 used 128-bit RSA. Is this the same in 3.5, or has this changed?
Thanks

Hi, all here,
I am having a question about plug-in algorithms in SQL Server 2005. Since we are able to implement our own algorithms in SQL Server 2005 analysis services architecture, so my question is: what benefits can to a great extent be achieved? Like say, we are going to implement a plug-in algorithm, so what considerations should be concerned?
Thanks a lot in advance for any guidance and help.

Hi, all here,
I am having a more considertaion about Data Mining plug-in algorithms. When we say we are going to embed a uesr plug-in algorithm, so what is the context for that ? I mean in which case then we thing we need to embed a user plug-in algortihm? I know when we say we are going to embed a user costomermized plug-in algorithm, it means we want something more costomized. But what kind of customized features are generally concerned? Is it independant for different market sectors?
I dont think we can just try to embed a plug-in algorithm then compete it with avaialble algorithms to see which one is with better prediction accuracy?
Would please someone here give me some guidances about that?

I am working in SQL Server Master Data Services Version 11.0.5058.0 (SP 2).
I have been asked to group all the financial attributes together. When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Then I reach a section of attributes where it leap frogs over 24 attributes.
It appears these 24 attributes are in a subgroup but there are no attribute groups and I removed the subscription view from the entity. If I move one of the 24 attributes in the group, it moves it outside of the 24 attributes.
This is under leaf member attributes. There are no collection or consolidated groups.

I'm using a DW from Northwind database to build a cube to do some analitical taks. I already create the cube and now I am "cleaning" the dimensions. I'm having some difficults to understand the logical off this part. The reason is that When I create the Data Source View, I only import the Foreign Keys that connect the Dimensions to Fact_Table. I have to drag the attributes of Dimension from Data Source View to the tab attributes?
Imagine this:
I have the following dimension:
Dim_Customer:
Customer_ID
Name_Customer
Job_Function
Date_of_Birth
Contact
Address
City
Country
When I create the cube only Customer_ID appears in attributes tab, it's normal?
One more question:
I don't want to create a hierarchy like:
Customer ID -> Name_Customer
Customer ID -> Date_of_Birth
Customer ID -> Address
Customer ID -> City
Customer ID -> Country
My idea is to create the following hierarchy:
Name_Customer -> Date_of_Birth -> Address -> City -> Country
But the first hierarchy that I show is always appears to me. Do you know what is happens?

Hello all-
I have a specification table that has some attributes defined.
SpecId - Id of the specification
Attribute - Attribute of the spec. (Like Color, HP etc)
Value - Is the value of the attribute
Then I have a car table that actually has information about the cars. Intention is to take each specification and match the cars that match the specification. If the car has more attributes than the spec, we ignore the extra attributes for the match. But if the car has less attributes, we don't even consider the car as a match (even if the attributes present, match). To summarize, the car's attributes should be >= spec's attributes.
The code I have below is bad because I am joining the same tables twice. In addition, it fails in the condition "the car's attributes should be >= spec's attributes"
Any help is greatly appreciated.
DECLARE @Specification TABLE
(SpecId VARCHAR(10),
AttributeVARCHAR(100),
ValueVARCHAR(100))
DECLARE @Car TABLE
(CarName VARCHAR(10),
AttributeVARCHAR(100),
ValueVARCHAR(100))
INSERT INTO @Specification VALUES ('S1', 'Type', 'Sedan')
INSERT INTO @Specification VALUES ('S1', 'Transmission', 'Auto')
INSERT INTO @Specification VALUES ('S1', 'HP', '220')

INSERT INTO @Car VALUES ('Explorer', 'Transmission', 'Manual')
SELECT DISTINCT Spec.SpecId, Car.CarName
FROM @Specification Spec
INNER JOIN @Car Car
ON Spec.Attribute = Car.Attribute
AND Spec.Value = Car.Value
WHERE Spec.SpecId NOT IN (SELECT Spec.SpecId

I am using db keyowrds as attributes in my table such as from, to and date. These are enclosed in [] in SQL Server Enterprise Manager. I'm just asking if doing this is a bad idea? Reason being these are the most applicable names for these attributes but don't want to run into problems further down the line.

Have a report that I want to keep certain attributes and as long as the report contains this certain attribute, bring all other attributes with it. Better with an example. In this report I am specifically looking for attribute "Alcohol", if I find this attribute I want to include all others that fit with this record's Primary Key which could include, "Drugs","Arson","Vandalism", etc. Problem is when I try to use a paramater or filter I get the "Alcohol" Attribute but not the "Drugs","Arson","Vandalism", etc. Conversely since I dont have any filter/paramater set I get everything even if it does not include "Alcohol"
suggestions??
thansk in advance

Bit of a design question as I'm interested to know if anyone's done anythign like this...This is my main table (ish) Thing(ThingId, Ref)I then need to be able to give this "Thing" any number of attributes. Thing1 - Type:Red, Location:LondonThing2 - Type:Blue, Height:400, Width: 300Thing3 - Height:500, Location:Norwich But I have no idea how to model this in the database - it needs to be in such a way that I can add a Thing and all its attributes in one database hit basically (is there a stored procedure you could pass an array into?) My initial thoughts were to have Thing(ThingId, Ref) Attribute(AttributeId, ThingId*, AttributeTypeId*, Value) AttributeType(AttributeTypeId, Description) Is that completely mad? It seems like quite a lot of data accesses to enter a ThingIt could be Thing(ThingId, Ref, Type, Location, Height, Width) but then when "Thing - Color:White" comes along the model is stuffed Any ideas? (hope that makes sense)

In query analyzer, what is the command to tell me the attributes of the entities in a table? In oracle I can use the describe command. I know their is a way to do it in Query analyzer but I can't remember how. Also I can look visually by expanding the node of the table. But if I can do this through the command line in query analayzer, it is sometimes quicker.
Example. I want to find out about a table named "Employee"
What command would I type that would tell me all of the columns/attributes in that table, and the data types which they are?

I have a few tables that have an disabled attribute using a BIT datatype. A lot of my queries on the front end look like:
SELECT *
FROM TableA
WHERE disabled <> 1
There's usually some other constraints on the query (get TOP 10 and greater than a certain date for example). Right now my tables are very small (only a couple thousand rows). I don't anticipate these tables having more than 100,000 rows.
Right now let's say there's only a CLUSTERED INDEX on the date field, and regular INDEXES on the identity field and perhaps some other UNIQUE name in the table.
Unless I am doing ranged queries on the CLUSTERED INDEXED field, I'm going to be performing table scans almost every time, right?
This sort of goes along with another question:
Say you run the following (SQL Server):
CREATE TABLE TestA (
[id] INT IDENTITY (1, 1) PRIMARY KEY,
disabled BIT DEFAULT 0
)
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
Since [id] is a PK there will be a CLUSTERED INDEX placed on it. My question is; what does the optimizer do when you perform the following query?
SELECT TOP 3 *
FROM TestA
WHERE disabled <> '1'
My assumption is that since there's a CLUSTERED INDEX it will simply iterate through every tuple and check to see if disabled is not '1'. If my assumption is correct then these kind of boolean fields aren't a big deal if TOP queries are performed on a CLUSTERED INDEX.
So I guess what I am getting at is: Are bit attributes a sign of bad design? As tables get larger will performance degrade significantly? Would a better design be to have a seperate table of disabled items (which may result in large NOT IN subqueries)?
Any information on his would be greatly appreciated.

I have a question about storing the history of particular objects in a database. For example, if I had a table of "People" which had fields "PersonId", "Name", "PhoneNumber", "Height", "Weight", "Proffession" the data in every field stored for each person can change over time, except for the "PersonId", of course, which is why it is included.
I would like to be able to view a persons attributes at any point in time and therefore need to maintain a history. The currenct approach in place is to archive images of the whole table at certain points in time, which is unacceptable as it misses some changes, is not very accessible and also stores data which does not change.
My solution would be to created seperate tables for each changing attribute and have corresponding date for each change. For example, for phone numbers have a table "PeoplePhoneNumbers" with fields "PersonId","PhoneNumber" and "ChangeDate". A few shortcomings I can see in this approach is that firstly there will be many tables, one for each changing attribute, which can be in far greater number than those mentioned. Secondly, joins will have to created between every attribute table to get the orignal single table form, although I don't see this as a very important issue.
I am wondering; is there a more elegent way to structure for objects of this changing nature, or is having seperate tables for each changing attribute the best solution? I'm sure this is a very common issue. Thanks very much for the help,
Mike

We have an entity such as a documentSearchKey that contains attribtes about a particular document. This document can have 1-N number of search keys or attributes. The classic Employee Table is a good example for a horizontal listing of attributes (fname, lname, SS#, address, etc.) because the employee entity has a "fixed" number of attributes so we can add columns across.
For the documentSearchKey entity attributes can be considered search keys or where clause values.
The documentSearchKey entity has variable number of attributes (docType A has 5 keys, docType B has 15 keys, etc) For this example each docType lives inside its on table so there is not a problem with mixing a variable number attributes inside the same table i.e. we will assume this table has 20 keys vertical or 20 columns horizontal as defined below.
The problem is whether or not to add 20 columns across or to add 3 columns and create a non-normalized DB so additional keys can be added at will.
The proposed table now contains 3 columns (docID, KeyID, KeyValue). Of course, 10 keys for 1 million records create 10 million rows Versus the traditional table with 1 million records always has 1 million records(keys are cols) where some columns contain blanks or nulls.
Which design is better in terms of searching and performance?
Also, books and links are welcome as well. This is a specific question to a production issue.
Thank You Very Much !

I apologize ahead of time for the long post...Background:Working on a CRM type custom application. The application is for anevent management company. The company will provide the application forother organizations to manage their own events. The events includeconferences, corp meetings, sales meetings, etc...An event planner will define what information is needed for an attendeeto register for an event. We will be providing a standard list ofattributes for the event planner to select from. This list includespersonal information (name, address, phone numbers), air travelinformation (preferred carriers, departure airports, etc...), hotelinformation, etc...we've included all of the information available tous from the business's previous experience. As far as the databasegoes, all of the standard information given to use will be normalized.The problem is each event may have unique information that needs to becollected that is not part of the standard list of attributes. Forexample, if McBurgers is planning an event, the event planner may wantto collect an attendee's McBurger employee code.Depending on the uniqueness of the event, there may be up to 200 uniqueattributes defined for it. This number comes from researching eventsplanned in the last 5 years. The number of attendees for an event rangefrom 100 to 10,000. The company expects about 3000 events per year.Database DesignI've done a fair amount of research and found a couple of options tomeet our requirements, more specifically the need for event planners todefine custom attributes for an event.1-)DynamicColumns:Add an Event specific custom attributes table. The table would looksomething like this:Event_McBurger05AttendeeID | McBurgerEmployeeCode | HiredDate | SomeOtherAttribute-Join Bytes! | AxEt356 | 01/01/2004 | Other val 22-)EAV:Add an EAV (entity, attribute, value) table. The table would looksomething like this:Event_AttributesEventCode | AttendeeID | Attribute | Value-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | HiredDate | 01/01/2004McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2The Value attribute would be a character (probably varchar) datatype.3-)Stronger Typed EAVHave an EAV table for each data type. The tables would look somethinglike this:Event_CharAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2Event_DateAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | HiredDate | 01/01/2004There would be one Event_[DataType]Attribute table for each of thedatatypes allowed.Pros/Cons1-)DynamicColumnsPros:-Data integrity can be enforced-Simpler queries for reporting-Clearer data model for understanding data storedCons:-Row size limitation of 8k must be managed (probably need to addanother table if run out of room.-Stored procedures for CRUD operations would need to dynamicallycreated ORNeed to use dynamic SQL on the database or application.-Adding/Removing columns on the fly can be very error prone2-)EAVPros-Static CRUD stored procsCons-No data integrity-Complex queries for reporting-Worse performance than option 1.-Table can get BIG...fast.3-)Stronger Typed EAVPros-Static CRUD stored procs-Better data type integrity than EAVCons-Complex queries for reporting-Worse performance than option 1-Table can get BIG...fast.If you are still reading this...thank you!The Questions:-Are there other options other than the 3 described above? Or are thesepretty much it with slight variants.-Does anyone see any missing Pros/Cons for any of the options thatshould be considered?-Is there a "preferred" method for what I am trying to do?I suspect this will come down to the lesser of three devils. Justtrying to figure out which of the three it is.We have prototyped the three options and are leaning towards option 1and 3.Any comments/suggestions are appreciated.Thx

Hi, all here,
Thank you very much for your kind attention.
I am having a question about Microsoft Clustering algorithm here. When we train the clustering model, we gain the clusters based on the model training. So what are the relationship among all attributes within each cluster? When we sumarize the characteristics for each cluster, for example, based on criteria attribute A=X, we got the darker cluster for this criteria, along with this characteristics (A=X), we also got other characteristics, so what is the exact relationship among all these chracteristics? It seemed they dont have any relationship to each other at all? (A=X dose not mean most likely B=Y if A=X?, what it means only is within this cluster, most likely A=X and B=Y etc. and A=X has the largest population within this cluster). I therefore cant see these chracteristics really interested.
Looking forward to any guidance and advices for that.
With best regards,
Yours sincerely,

FROM [Adventure Works]
WHERE ( [Measures].[Reseller Sales Amount] )
Can someone please explain me why I'm getting this result:
