Hi Stanley,
Can you help with this:
You might encode the
feature to vector and serialize them to the file system by MapReduce to
reduce cost on data parsing.
And I have started a new thread on
http://mail-archives.apache.org/mod_mbox/mahout-dev/201108.mbox/%3cCACOCgckzcAm4V8y3CQhnBWtUy9jVgAbK
For small problems, you can even retain the training data in memory for
maximum speed.

Can you be more specific about what you have and what you want?
The book Mahout in Action provides quite a lot of details with sample code
for a server farm.
The TrainNewsGroups example provides code that you can copy.
Do you have these resources? Do you want more? Did you want more theory?

Hi Ted,
Video and PDF are accessible from here.
Very instructive. Tks!
You were talking about 'Mahout in Action' book.
I suppose you were referring about the EBook version.
Hard copy are not yet available as far as I can read on
http://www.manning.com/owen/.
Any idea on shipping date ?
Tks,

Eric the book is still being written, but you can buy the interim PDF
version from the site. It seems quite complete (save for a few typos here
and there).
The publisher will email you with updates as the document chapters are being
finalized. You also have the option of having the dead-tree editi
Yeah, it works for me. Nice lecture!

Yes. That's the one.
The hard copy should be out before long. The final passes by the production
editors are happening now.

The book is all there. All that is happening now are tiny edits and final
production formatting.

Huh?
What program are you talking about?

You can't do that directly.
You can use the http address of the file in HDFS.
Note also that trainlogistic and runlogistic are intended pretty much only
for simple demonstration purposes.
For large scale data, you should use AdaptiveLogisticRegression

Go for it.
Produce a JIRA and a patch.

In the meantime, look at building your own command line tool for
AdaptiveLogisticRegression.

Great idea. Why don't you implement something like what you need? Others
will be happy to contribute improvements.

I have write a command line program proto type for RunAdaptiveLogistic,
1. How can I make it invokeable from mahout
2. Can you help to fine tune the AdaptiveLogisticRegression creating
and settings to make it make sense.

Attach a diff file with the extension .patch. Create the diff at the mahout

Hi Ted,
Are interval, averagingWindow, thread count, and prior Fuction the
only four tuneable options of AdaptiveLogisticRegression?

There are a few others as well.

public void setInterval(int minInterval, int maxInterval)
public void setPoolSize(int poolSize)
