Fwd: Algorithms in Mahout
I have gone through http://mahout.apache.org for some data mining
algorithms already implemented on the Hadoop plattform.
>From that i understood that
1. Kmeans
2. Decision Tree
3. Navie Bayes
Have implementation in hadoop platform
And for
4. DBscan
5. k-mearesr neighbr
6. svm
7. Logistic Regression
8. Neural n/w
9. Aprori
it is not there in Mahout.
Is that inference right?

Sorry, for the confusion, we are currently reworking the wiki.

k nearest neibhor, svm, logistic regression, neural nets exist in mahout .
just type mahout and press enter you ll see list of algorithms available
and type mahout algo-name -h to get detailed information about how to use
/configure them

Dhruv,
Could u update the patch to present trunk codebase and also create a Wiki page for this?

Distributed Hidden Markov Model trainer using Baum Welch Algorithm is also
available as a patch. Please see the JIRA issue MAHOUT-627.

Streaming k-means isn't strictly a knn implementation. It is a k-means
clustering application.

Hi Unmesha,
please also consult JIRA as a source for algorithm, there you find implementations or discussions:
e.g. for neural networks a.k.a multilayer perceptrons:
https://issues.apache.org/jira/browse/MAHOUT-1265
https://issues.apache.org/jira/browse/MAHOUT-976
SVM:
https://issues.apache.org/jira/browse/MAHOUT-334
https://issues.apache.org/jira/browse/MAHOUT-232
https://issues.apache.org/jira/browse/MAHOUT-14
https://issues.apache.org/jira/browse/MAHOUT-227
For aprior Mahout offered an alternative Parallel Frequent Pattern Mining. This will be retired after 0.8
https://cwiki.apache.org/confluence/display/MAHOUT/Parallel+Frequent+Pattern+Mining
There are/were multiple kNN implementation in Mahout:
Recommender knn http://grepcode.com/file/repo1.maven.org/maven2/org.apache.mahout/mahout-core/0.6/org/apache/mahout/cf/taste/impl/recommender/knn/Optimizer.java (will be removed for 0.9)
stream knn https://github.com/tdunning/knn/blob/master/src/main/java/org/apache/mahout/knn/cluster/StreamingKMeans.java
normal knn
Hope that helps
Manuel
