""Have a loose, informal organization of all the analytics folks that are sprinkled througout the business lines."
Anthony, I'd have to disagree with this statement, unless I didn't understand correctly what you're saying.…"

"Randy,
Here are my opinions in regards to your questions:
"Here are two interesting questions: 1. Do businesses benefit from an ‘enterprise wide’ analytics group?"
Yes, they do. I'm a part of such a centralized…"

"Cool, nice to now that Rapid Miner has it.
I was thinking of spending some time in near future to learn their application.
Too bad TSVM is not in their community edition. That would have been a really good incentive to start learning and using it :)"
Stephen Cronin replied to Paul Wilson's discussion Transductive SVM for semi supervised learning in the group Data Mining
"confirmed, and my friend who uses the enterprise rapid miner at work says it does a decent job. I wonder what the cost tag is associated with it."
Steffen Springer replied to Paul Wilson's discussion Transductive SVM for semi supervised learning in the group Data Mining
"I am not that sure, but I think that the commercial version of rapidminer includes a implementation of transductive svm (in java).
I dream of the day when http://mahout.apache.org/ includes an implementation...…"

"Very interesting. I would love to collaborate on getting a MATLAB version of this up and running to be compiled into C. only problem I see is that SMO scales as an O(n^2) or with some clever tricks a little less then that so it would depend on the…"

"Hi Stephen,
I'd like to use TSVM in reject inferencing situations.
Say for example a company sends mail to a group of customers and wants to build a model on future customer's likelihood to respond.
Well, usually companies usually…"

"Paul what are you using a TSVM for? I've been looking for a reason to code this up in MATLAB and add it to my companies libraries (actually a TSMO for the speedup). I think you will have some trouble finding this open source at least until one…"

Transductive SVM for semi supervised learning
Does anyone know of any software that has Transductive SVM for semi supervised learning available as a user friendly graphic user interface (GUI), preferably open source?For those of you who are not familiar Transductive support vector machines extend SVMs in that they could also treat partially labeled data in semi-supervised learning.ThanksSee More

"Depends on may factors, but if analytics is to be a shared, centralized group (i.e. not report to silos/individual line of business like, say CRM), there should be a separate stream with a VP, Analytics type of position available for optimum…"
Ralph Winters replied to Paul Wilson's discussion Decreasing Dataset Dimensionality in the group Data Mining
"How are you doing your prediction? Most regression type models will give you a chi-square number to test that the model parameter for that category is 0. You could try collapsing these categories into one, unless it makes no business sense.

Jeff replied to Paul Wilson's discussion Decreasing Dataset Dimensionality in the group Data Mining
"If this response is about my suggestion for a decision tree, the implementation of CHAID I use with IBM Modeler uses an F-test when the target is interval - not a chi square of course. You could bin the interval target and use a chi square but there…"

"Hi,
Are you talking about the Chi-squared method?"
DataLLigence replied to Paul Wilson's discussion Decreasing Dataset Dimensionality in the group Data Mining
"Right now, I can think of proportions only.
Your dependent is 1, 2 and 3. And the levels of your category variable are A, B, C and D. Do a cross-tab for these 2 variables.
If A and C have similar proportions of transactions or customers falling in…"
Jeff replied to Paul Wilson's discussion Decreasing Dataset Dimensionality in the group Data Mining
"Hi Paul-
Consider using a regression tree. I use CHAID to bin nominals with respect to a categorical target, but it will accept a numeric target as well (most implementation I have seen). If you allow only one level from the root with just the…"

Decreasing Dataset Dimensionality
Hi everyone,I have a nominal (unordered) categorical predictor variable in mydataset that has too many levels I'd like to bin or group with respectto my interval scaled dependent variable.There are quite a few ways to discretize interval scaled inputs withrespect to the categorical output, but I'm having trouble finding theprocedure that will do opposite (bin categorical input with respect tointerval output).Any tips would be greatly appreciated !!See More
