------------------------------------
Just dropping a note to say that I've tried out this patch, getting output as:
281.17521793362766 = Norm of solution
0.0577053057402274 = avg Loss of solution
0.006500000000000002 = avg zero-one error of solution
0.19829291470704108 = primal objective of solution
0.17299428453573593 = avg Loss over test
0.025 = avg zero-one error over test
97.5% = Testing Accuracy
Looks great so far to me (although I haven't dug in deeply into the code yet).
Awesome work so far!
> Implementation of sequential SVM solver based on Pegasos

> Key: MAHOUT-232
> URL: https://issues.apache.org/jira/browse/MAHOUT-232
> Project: Mahout
> Issue Type: New Feature
> Affects Versions: 0.1
> Reporter: zhao zhendong
> Attachments: SequentialSVM_0.1.patch
>
>
> After discussed with guys in this community, I decided to re-implement a
> Sequential SVM solver based on Pegasos for Mahout platform (mahout command
> line style, SparseMatrix and SparseVector etc.) , Eventually, it will
> support HDFS.
> The plan of Sequential Pegasos:
> 1 Supporting the general file system ( almost finished );
> 2 Supporting HDFS;
