I finally managed to make it run, I had to format the class label in the
input file with a / in the name so I put Yes/1 or No/0 instead of just 1 or
0.
But then I noticed when testing the model that it doesn't classify all the
data :
14/02/25 16:16:30 INFO mapred.JobClient: Map-Reduce Framework
For information purpose, this is the program creating the sequence file :
public static void main(String[] args) throws IOException,
InterruptedException, ClassNotFoundException {
Configuration conf = new Configuration(true);
FileSystem fs = FileSystem.get(conf);
// The input file is not in
Hi again,
I finally set my mind on going through java to make a sequence file for the
naive bayes,
but I still can't manage to find anyplace stating exactly what should be in
the sequence file
for mahout to process it with Naive Bayes.
I tried virtually every piece of code i found related to this
NaiveBayes expects a SequenceFile as input. The key is the class label
as Text, the value are the features as VectorWritable.

Thanks, that's about the clearest answer I got so far :)

Kevin,
While this is fresh in your mind can you prepare a javadoc patch that would
have helped you out? And suggest other doc patches as well?

I'll do that as soon as I manage to make it work ^^', that's a great idea !
I'm stuck with this for now :
public static void main(String[] args) throws IOException,
InterruptedException, ClassNotFoundException {
Configuration conf = new Configuration(true);
FileSystem fs =
Hi I'm trying to apply a Naive Bayes Classifier to a large CSV file from
the command line.
I know I have to feed the classifier with a seq file, so I tried to put my
csv into one using the command seqdirectory, but even when I try with a
really small csv (less than 100Mo) I instantly get an
To convert input CSV to vectors, u can either:
a) Use CSVIterator
b) use InputDriver
Either of the above should generate vectors from input CSV that could then be
fed into Mahout classifier/clustering jobs.

Hi and thanks !
What about the command line, is there a way to do that using the existing
command line ?

This relates to a previous question I have: Does mahout have a concept of
adapters which allow us to read data csv style data with filters to create
exact format for its various inputs (i.e. Recommender three column format).?
If not is it worth a jira?
