Hello,
I use seq2sparse with -wt tfidf option and execute the kmeans pipeline. If
new data comes at a later date, should I decide which cluster it belongs
using Listing 9.4 News clustering using canopy generation and k-means
clustering in Mahout in Action, or is there a better/more generic (i.e.
You generally want to do linguistic pre-processing (finding phrases,
synonymizing certain forms such as abbreviations, tokenizing, dropping stop
words, removing boilerplate, removing tables) before doing vectorization.
Altogether, these form pre-processing.
To classify books, you need to
Dear Suresh,
I am also working in Classification of books.
First of all I collect a meta-data of my e-books, after collecting a
meta-data than I start my second level to pre-process an e-book. In
pre-processing, I collect information regarding *books title, chapter
titles sections, subsection
Hi,
Thanks for your reply.
I have got the table of contents, meta-data, title, author, etc for the
books.
Can you please tell me the next steps to proceed.
I have read in Mahout In Action book that there are few tools available for
vectorization Ex: Lucene analyzers, Mahout vector encoders
Can
Hi all - there is a project at MIT called FlexGP that has done more work on
this.
http://groups.csail.mit.edu/EVO-DesignOpt/groupWebSite/index.php?n=Site.FlexGP
Unfortunately I can't find a download for the code so I suppose that it's not
opensource, however you might like to contact these
Hi guys,
I'm new with mahout. I'm using it for an experimentation with
recommender system.
I'm using this code:
import org.apache.mahout.cf.taste.impl.neighborhood.*;
import org.apache.mahout.cf.taste.impl.recommender.*;
import org.apache.mahout.cf.taste.impl.similarity.*;
import
Does the csv file that you load contain user with id 1 ?

Here's the new URL for Mahout 0.9 Release:

For those volunteering to test this, some of the things to be verified:
a) Verify that u can unpack the release (tar or zip)
b) Verify u r
Please hold off on this, screwed up the future development version#. Have to
redo this again.
Sorry about that.

Hi,
Clarifying my question a little bit:
How can I create a vector from a single text document to conform the schema
of the collection of vectors that I created using seq2sparse before?
I want to use it to find the closest centroid to a text document that is
submitted by a client

This is not a maven issue.
Andrew, r u on Mac OS 10.8? If so u would be seeing these errors.
These errors being spewed by Carrot RandomizedRunner and per the conversation
in Mahout-1345 this happens on Mac OS X due to an issue in Lucene 4.3.1 and
below that was fixed in later Lucene releases.
Suneel,
Mahout build is ok.
However at least 3 Integration test cases fail as follow :
Failed tests:
ARFFVectorIterableTest.testNumerics:237-Assert.assertEquals:592-Assert.assertEquals:494-Assert.failNotEquals:743-Assert.fail:88
expected:1.0 but was:NaN
Mahout has an example of using naive bayes to classify 20 news group. but
how to just classify paragraphs (e.g. twitter message, movie review) in
text files such as:
Text files has content like:
--
text paragraph 1 class
See
http://chimpler.wordpress.com/2013/03/13/using-the-mahout-naive-bayes-classifier-to-automatically-classify-twitter-messages/
for classifying twitter messages.
Lucene has support for ngrams, stopwords, porter stemmer, snowball stemmer,
language specific analyzers etc...
Mahout uses Lucene
Suneel, thanks a lot.
I assume the example you mentioned was generating a numerical vector for
each paragraph, is it right?
now, to further improve the performance, I may add other features from
other data set into this vector and make it much longer, then use the
enriched vector for naive
