We're launching SinglyClassifier2 simply by Eclipse on Hadoop environment, if
this was your question. The Mahout source that we use was checked out not long
ago. Mahout is packaged with our SinglyClassifier2 and then thrown at our
cluster to run directly through SinglyClassifier2's main()

> Project: Mahout
> Issue Type: Bug
> Components: Classification
> Affects Versions: 0.4
> Environment: Linux
> Reporter: Robin Swezey
> Assignee: Robin Anil
> Priority: Minor
> Labels: bayesian, classification
> Fix For: 0.5

> The array returned for a n-best call to classifyDocument is sorted ascendant
> instead of descendant.
> Ex:
> {quote}
> 47-best: [ClassifierResult\{category='香川県', score=32.28281232047167\},
> ClassifierResult\{category='宮崎県', score=32.28969992600906\}, ......,
> ClassifierResult\{category='愛知県', score=32.487981016587796\},
> ClassifierResult\{category='東京都', score=32.49189358054859\},
> ClassifierResult\{category='北海道', score=32.49811200756193\}]
> {quote}
> (classification of documents for Japanese prefectures)
> Inside the classifyDocument method, just before the return statement we found
> this line:
> {quote}
> Collections.reverse(result);
> {quote}
> Is this a mistake or a design choice? (we are not sure, hence the "Minor"
> priority)
