Teradata Universe Beijing 2008 (i am presenting there)
-
I am presenting at the Teradata Universe Beijing this year. I will be the first speaker for the telecommunications sessions (the other sessions being 'Banking' and 'National Accounts').
My talk will be a high level summary of the customer analytics we conduct, how we present to corporate executives, and the benefits our analysis has brought our customers and the company.
It's a single day conference, and I'll be taking a few extra days for sight seeing in Beijing with my wife.
Feel free to say hello if you see me at the Teradata Universe Beijing 2008, May 30th at The Kerry Centre Hotel, Beijing.
Cheers
Tim

Use C5.0 to study all attributes leading to outcome
-
Is there any way to relax constraints to get more rules towards a target outcome? I just want to derive the information gain statistics on individual attributes.

Association Rule
-
Hello...
I'm working on my script about Association rule on transaction database using Java.
I am a newbie on java programming. And I have so many difficulties on it.
May I have some script documentation about association rule ( apriori algorithm ) using java please ?
My email : naldy_s@yahoo.com
Thanks a lot.

Best of two outputs (with confidence values) Clementine
-
Hi all
I have two Clementine stream one trained on back prop and another with radial basis.
The output is a binary field for prediction. I got two confidence values one for each of the stream, I am not very sure if I just take the prediction from the stream with higher confidence value or do I need to apply any equation (if any). Please help...
I did read an earlier thread http://www.kdkeys.net/forums/thread/7236.aspx
I don't know if I can use the same logic here, please advice, thanks in advance for your time.

Need some codes
-
Hi,
I am a data mining student, we use Weka Tools for our practicals.
I need the source codes for some algorithms implemented in any language (C/C++/VB)
If anyone has the source codes for the following algorithms (or the links where I can find them), plz mail it to me at chirag.s1@gmail.com
Thanks.
1. Apriori (Large Item sets and Association Rules)
2. Agglomerative Algorithm
3. Decision Tree (ID3 / C4.5 / C5.0 anyone)
4. K-Means Clustering algorithm

How to explain differences between CRT and C5.0?
-
Hi,
I'm usingpu CRT and C5.0 to model decision trees. Though this works pretty good I'am unbable comprehend the different output I get with CRT and C5.0.
I read the manuals and did some google research but could not find any information what actually causes the C5.0 algorithm to produce different output compared to CRT. Unfortunately C5.0 is closed source so there is not much information about its internals.
Does anyone have an idea where to find out more?
Cheers,
Peter

Working with model node outputs
-
I have an SPSS source file supplying a K-Means model and a Binomial Logistic Regression model in Clementine 12. The BLR model is looking at a mere 1298 cases. I'd like to extract the probabilities from that model so I can score my main data file, but when I go to execute the spss export file node that's connected to my generated model node via a Type node, it crashes the Clementine Local Server.
Likewise, with the cluster ID variable from the K-Means model, I'm having a heck of a time producing an output file that contains this information. I looked at the help files and saw the information about connecting an Analysis or Table node and then generating a derive node, but the derive node doesn't seem to select the cluster variable? I've been surprised by how difficult it's been to dig up clear information on what seems like it would be a pretty common practice (producing a model, then applying the output of that model to existing data. Do I need to include an SPSS output node somewhere and write syntax to get what I want?
Any thoughts are appreciated.

Detect random variables and depedency between variables
-
Hi all,
I'm not a guy from Data Mining field. However, my research leads me to a difficult problem (which seems to be related to data mining field). The problem is:
I have a set of variables (for example: variables A,B,C,D and E).
- Some variables (for example A,B and D) are random variables. Those variables can have any value.
- The other variables are depedent on those random variable (For example: C = A+B, E = A*B+D).
Now given a set of variable: A,B,C,D,E and a dataset for those variable. For example:
A B C D E
============
1 5 6 7 12
2 3 5 3 9
......
I have no information about "Which variables are random variable",
"which variables are depedent on the other variables" or "The
dependency of variables" . All I have is a set of variable
and a data set.
Now, from the data set, I want to find out which variables are random variable and which are not.
How do I do that? Which algorithm should I use?
Could you pls give me some ideas or just some keywords so that I can "google".Thanks in advance
Ball Agile.
