BW Data Mining

Hello!
I need information about the following BW Data Mining topics. Hope, someone can help me?
-What 3rd Party Tools are available für Data Mining? (I just know "IBM Intelligent Miner")
-Does someone have experiences with performance of the DM-algorithms? System requirements? Mass data?
-Are there possibilities to improve the performance?
-What is known about new features in Netweaver BI 7.0 for DM?
-Does someone have special experiences in DM in the automotive industy? Are there typical business processes known, which are useful for BW Data Mining?
Thank you for help!
Regards,
Peter

Hallo!
I need different information about BW data mining.
One thing is, what are typical business scenarios for the different algorithms. So it is easy to find such for decision trees, association analysis and maybe for ABC analysis. But i have little problems to find real scenarios vor weighted score tables and regression analysis. It would be helpful to hear about some.
I have to write a paper for my company about data mining with bw. While we have no experiences in this area I´m looking here for people having.
Also Performance. The problem is not to try out with APD and Data Mining models. But to find experiences with this.
Good or bad performance with this or this algo? Or how can I optimize performance for mass data?
After this I have to design typical business scenarios. Especially for automotive area if possible.
So what the question for me is, what is possible with the algorithms? Where are problems with them?
It would be great if you could provide me with more information about your experiences in this area.
Thanks,
Peter

Data Mining on data specified and filtered by the user in runtime

Hi Experts,
i am new to Data Mining in SAP BI (we are on BI 7.0 SP Level 20). I familiarised myself with APD and Data Mining by reading some interesting and useful threads in this forum and some other resources. Therefore I got a understanding about the topic and was able to create basic data mining model for an association analysis and an corresponding APD for it and write the results into a DSO by using the data source. But for now I was not able to find a solution for a concrete customer requirement.
The user shall be able to select an article, a retail location and a month and get the top n combinations sold with that article in the particular location and month. For that he may not access the data mining workbench or any other SAP internal tools but he shall be able to start the analysis out of the portal (preferable a query).
We had some thoughts on the scenario. The first idea would be to create an APD for every location for the last month. As we need to cover more than 100 locations, this would not be practicable. Therefore I think it would be necessary, that the user can select the particular filters, and the data mining would then be executed with the given input.
The other idea was to use a query as source. The user would start this query and filter location and month in it. The result of the query could then be used as the source for the APD with the association analysis. Therefore we would need to create a jump point from that query, which starts the APD with that results. After that the user should be able to start a result query, which displays the result of the association analysis (ideally this result query would start automatically, but starting it manually would be ok, too).
So, I have the following questions for these scenarios:
1.) Is it possible to create variants of a single APD, for automatically doing the data mining for the different locations?
2.) is it possible to start an APD out of a query, with the particular results regarding filtering?
3.) Can we place a query directly on the data mining results (how?) or do we need to write the data mining results in a DSO first?
4.) What about the performance? Would it be practicable to do the data mining in runtime with the user waiting?
5.) Is the idea realistic at all? Do you have any other idea how to accomplish the requirement (e.g. without APD but with a query, specific filter and conditions)?

Hi ,
you can see the example : go to se 80 then select BSP Application ,SBSPEXT_HTMLB   then select tableview.bsp , you will get some idea to be more clear for the code which you have written
DATA: tv TYPE REF TO CL_HTMLB_TABLEVIEW.
tv ?= cl_htmlb_manager=>get_data(
                         request = runtime->server->request
                          name    = 'tableView'
                              id      = ''tbl_o_table" ).
IF tv IS NOT INITIAL.
DATA: tv_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
tv_data = tv->data.
IF tv_data->prevSelectedRowIndex IS NOT INITIAL.
FIELD-SYMBOLS: <row> LIKE LINE OF sflight.
    READ TABLE ur tablename INDEX tv_data->prevSelectedRowIndex ASSIGNING <row>.
    DATA value TYPE STRING.
    value = tv_data->GET_CELL_ID( row_index    =
                               tv_data->prevSelectedRowIndex
                                  column_index = '1' ).
endif.

Data Mining overflow error while loading the mining viewer

I developed a time series model that processes succesfully. The problem I have is that when I try to view the mining model viewer that displays the times series on a chart, I get the error below:
An error occurred while a prediction query was being executed:
'Error (Data mining): An overflow was encountered while converting a predicted value to the '' column, at line 1, column 33. A higher precision data type for the column is recommended.'.
ADDITIONAL INFORMATION:
Error (Data mining): An overflow was encountered while converting a predicted value to the '' column, at line 1, column 33. A higher precision data type for the column is recommended. (Microsoft OLE DB Provider for Analysis Services 2008 R2.)
It looks like the probability value (which is a float data type, for example 0.4452938765) is being stored in a particular column, and the data type of that column cannot contain the range of decimal places that the probability has.
I don't know which column to look for to change its data type like the error messages says. Would anyone have any idea?

Hello,
Thanks for your posting.
It is more related to Data Mining issue in this case. I move the thread to
Data Mining forum for better support. Thanks for your understanding.

Data mining Algorithms in Essbase

Hi,
Just wondering if anyone has used data mining algorithms provided within Essbase. Any thoughts or pointers towards more information will be helpful..
Thanks in Advance !!

In a 2009 persentation at Kscope from ODTUG titled little used features of Essbase, I went through how to use data moning. It is available on the odtug website. I do know that nothing has been done with the data mining modules in a long time as the team was disbanded since Oracle has other tools to do data mining.

What are the options for me for Data Mining tools?

I am new for data mining. I have a project for which we are asked to identify the relationships between variables we got and we were asked to come up with an algorithm from data mining. What are the options available for me as data mining tools and where
do I start from? How do I travel through this process. Please advice.

What software do I need to install to get "Data Mining Framework"

Hi,
from edelivery.oracle.com I have downloaded:
1. Hyperion Essbase - System 9 Release 9.3.1.2 Server Windows Installer
2. Essbase Administration Services Release 9.3.1 Windows Installer
I installed both software and I started Administration Services Console, log in etc. Essbase server is working fine.
In Administration Services Console I click on Essbase Servers | localhost | Data Mining | Algorithms and got error:
"message from server [Data Mining Framework is not available. Please contact Administrator].
It looks like I need to install some other software to have access to data mining features. Which software do I need to install?

Oracle Data Mining - How to use PREDICTION function with a regression model

I've been searching this site for Data Mining Q&A specifically related to prediction function and I wasn't able to find something useful on this topic. So I hope that posting it as a new thread will get useful answers for a beginner in oracle data mining.
So here is my issue with prediction function:
Given a table with 17 weeks of sales for a given product, I would like to do a forecast to predict the sales for the week 18th.
For that let's start preparing the necessary objects and data:
CREATE TABLE T_SALES
PURCHASE_WEEK DATE,
WEEK NUMBER,
SALES NUMBER
SET DEFINE OFF;
Insert into T_SALES
(PURCHASE_WEEK, WEEK, SALES)

There are a lot of linear regression models and approaches for sales forecast out on the market, however I will focus on what oracle 11g offers i.e. package SYS.DBMS_DATA_MINING to create a model using regression as mining function and then, once the model is created, to apply prediction function on the model.
Therefore I'll have to go through few steps:
i) normalization of data
CREATE OR REPLACE VIEW t_sales_norm AS
SELECT week,
sales,
(sales - 91423.95)/27238.3693126778 sales_norm
FROM t_sales;
whereas the numerical values are the mean and the standard deviation:
select avg(sales) from t_sales;
91423.95
select stddev(sales) from t_sales;
27238.3693126778
ii) auto-correlation. For the sake of simplicity, I will safely assume that there is no auto-correlation (no repetitive pattern in sales among the weeks). Therefore to define the lag data I will consider the whole set:
CREATE OR REPLACE VIEW t_sales_lag AS
SELECT a.*
FROM (SELECT week,
sales,
LAG(sales_norm, 1) OVER (ORDER BY week) L1,
LAG(sales_norm, 2) OVER (ORDER BY week) L2,
LAG(sales_norm, 3) OVER (ORDER BY week) L3,
LAG(sales_norm, 4) OVER (ORDER BY week) L4,
LAG(sales_norm, 5) OVER (ORDER BY week) L5,
LAG(sales_norm, 6) OVER (ORDER BY week) L6,
LAG(sales_norm, 7) OVER (ORDER BY week) L7,
LAG(sales_norm, 8) OVER (ORDER BY week) L8,
LAG(sales_norm, 9) OVER (ORDER BY week) L9,
LAG(sales_norm, 10) OVER (ORDER BY week) L10,
LAG(sales_norm, 11) OVER (ORDER BY week) L11,
LAG(sales_norm, 12) OVER (ORDER BY week) L12,
LAG(sales_norm, 13) OVER (ORDER BY week) L13,
LAG(sales_norm, 14) OVER (ORDER BY week) L14,
LAG(sales_norm, 15) OVER (ORDER BY week) L15,
LAG(sales_norm, 16) OVER (ORDER BY week) L16,
LAG(sales_norm, 17) OVER (ORDER BY week) L17
FROM t_sales_norm) a;
iii) choosing the training data. Again, I will choose the whole set of 17 weeks, as for this discussion in not relevant how big should be the set of training data.
CREATE OR REPLACE VIEW t_sales_train AS
SELECT week, sales,
L1, L2, L3, L4, L5, L6, L7, L8, L9, L10,
L11, L12, L13, L14, L15, L16, L17
FROM t_sales_lag a
WHERE week >= 1 AND week <= 17;
iv) build the model
-- exec SYS.DBMS_DATA_MINING.DROP_MODEL('t_SVM');
BEGIN
sys.DBMS_DATA_MINING.CREATE_MODEL( model_name => 't_SVM',
mining_function => dbms_data_mining.regression,
data_table_name => 't_sales_train',
case_id_column_name => 'week',
target_column_name => 'sales');
END;
v) finally, where I am confused is applying the prediction function against this model and making sense of the results.
On a search on Google I found 2 ways of applying this function to my case.
One way is the following:
SELECT week, sales,
PREDICTION(t_SVM USING
LAG(sales,1) OVER (ORDER BY week) as l1,
LAG(sales,2) OVER (ORDER BY week) as l2,
LAG(sales,3) OVER (ORDER BY week) as l3,
LAG(sales,4) OVER (ORDER BY week) as l4,
LAG(sales,5) OVER (ORDER BY week) as l5,
LAG(sales,6) OVER (ORDER BY week) as l6,
LAG(sales,7) OVER (ORDER BY week) as l7,
LAG(sales,8) OVER (ORDER BY week) as l8,
LAG(sales,9) OVER (ORDER BY week) as l9,
LAG(sales,10) OVER (ORDER BY week) as l10,
LAG(sales,11) OVER (ORDER BY week) as l11,
LAG(sales,12) OVER (ORDER BY week) as l12,
LAG(sales,13) OVER (ORDER BY week) as l13,
LAG(sales,14) OVER (ORDER BY week) as l14,
LAG(sales,15) OVER (ORDER BY week) as l15,
LAG(sales,16) OVER (ORDER BY week) as l16,
LAG(sales,17) OVER (ORDER BY week) as l17
) pred
FROM t_sales a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 104816.995823913
3, 77248, 104816.995823913
4, 106624, 104816.995823913
As you can see for the first row there is a value of 68861.084 and for the rest of 16 values is always one and the same 104816.995.
Question: where is my week 18 prediction ? or maybe I should say which one is it ?
Another way of using prediction even more confusing is against the lag table:
SELECT week, sales,
PREDICTION(t_svm USING a.*) pred
FROM t_sales_lag a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 75512.3642096908
3, 77248, 85711.5003385927
4, 106624, 98160.5009687461
Each row out of 17, its own 'prediction' result.
Same question: which one is my week 18th prediction ?
Thank you very much for all help that you can provide on this matter.
It is as always highly appreciated.

Here i am not sure how to predict B values . Please suggest the proper usage . Moreover In GUI (.NET windows form ) how user can give input and system can respond using the Q1

Beginner installing SQL Server 2014 for Excel Data Mining

Hello, I'm a complete beginner with servers but Im desperately trying to gain access to the SQL server for use with the data mining addin for excel.
Could someone please help. When I try to make a connection in Excel by choosing DATA MINING> <No Connection> New> it then asks me for a Server Name in the connect to Analysis Services box. How can I find out what my Sever name is please? I have
tried all sorts of names that I have found such as SQLEXPRESS or localhost but nothing works. It also tells me to 'Ensure that the Server is running'. Another error message I receive: No connection can be
made because 'the target machine actively refused it'.
I would be really grateful for some troubleshooting tips.
Thank you

Help with data mining add ins-excel 2010

I've wasted hours of my life now trying to figure out how to establish a connection on the data mining add in on excel 2010. I have installed and re-installed the microsoft sql server 2012 express multiple times and don't understand what it takes
to get this to work...Do I need SQL server and why? Do I need to download the adventureworks data file and why? (For some reason I was able to download it properly on my first sql server install, but when I went to work the data mining connection it
said the SQL browser must be connected...What???...I thought it was connected...there are no instructions on how that is fixed...Now I have reinstalled sql 2012 but can't download adventureworks...it says it can't
establish a connection...I am beyond the point of frustration)...I'm not a developer or know anything about code/programming, so a lot of the lingo is way over my head anyway when I am searching for troubleshooting solutions...I just want to be able to use
this feature in excel and it is upsetting me that I can't get it to work. I have followed step by step instructions, watched youtube videos, etc...nothing doing...If anyone can help me it would be greatly appreciated. Thanks.

>I'm not a developer or know anything about code/programming,
You have two choices:
1. Hire a programmer type to assist you
2. Become a programmer

Install it.
Download AdventureWorks2012 and AdventureWorksDW2012 sample databases and install them.
Desirable (but not for beginner): install Adventure Works Cube. This is how it looks after installation:

Data Mining in 9i

Hi All,
We have Oracle 9i Rel2, with OLAP and data miming option. The documents available in the net doesnt cover basic information on the installation/configuration/usage stuff. Can any one point me to a location (not oracle documents), where there is a step by step infor on hopw to get started with oracle data mining.
Any help will be really appreciated.

You need to copy the following jar files to your local machine
$ORACLE_HOME/jdbc/lib/classes12.jar
$ORACLE_HOME/lib/xmlparserv2.jar
$ORACLE_HOME/rdbms/jlib/jmscommon.jar
$ORACLE_HOME/rdbms/jlib/aqapi.jar
$ORACLE_HOME/rdbms/jlib/xsu12.jar
$ORACLE_HOME/dm/lib/odmapi.jar
I have downloaded all the required documents from metalink. In case you still need those, please mail me at [email protected]

How to get the Oracle Data Mining

Hi
I downloaded Oracle Database 10g r2 on Oracle's download website, and I want the ODM, but it is said in the white paper that ODM is a priced option. I'd like to know how to get it.

Data Mining is a priced option shipped with Oracle Enterprise Edition. You can get Data Mining option by installing Oracle 10gR2 and select 'general purpose' with the pre-configured database. Data Mining option is installed as default in that choice.
If for production purposes, customers do need to purchase Data Mining option lisence through Oracle sales.

Collation error when data mining

I'm trying to process a data mining model but keep getting this error: "Errors in the OLAP storage
engine: The sort order specified for distinct count records is incorrect. Errors in the OLAP storage engine: An error occurred while processing the..."
I changed my sql server collation to to Latin1_General_CS_AI with a compatibility level of 100, and in SSAS, I set it to Latin1_General_100 and "Case Sensitive" checked...but I still get the same error...am I not setting the collation correctly?

I changed my sql server collation to to Latin1_General_CS_AI ...
The SQL Server setting is just a default value for new databases, when you don't explicit define the collation in the CREATE DATABASE command; same for the database setting, also just a default value. The effective collation is defined on column level.

Processing a data mining structure throws an error

Processing a data mining structure throws an exception stating the following:
"Errors in the OLAP storage engine: An error occurred while the 'IDK' attribute of the 'Test IDK' dimension from the 'Project1' database was being processed."
"Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:17072643"
I am using a DB view as a DSV. It does not have a unique primary key. Since DB view is getting multiple results per IDK, the IDK repeats for multiple rows. The same IDK is defined as Key column for the mining model. Not sure if that is the
issue. Please help!
Thanks

Hi Shallu,
According to your description, you use a database view in the data source view that do not have a primary key, so you get the error
Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:1707264
when processing the project, right?
In this case, please refer to the links below which describe the similar issue.
