Array returned by classifier.bayes.algorithm.CBayesAlgorithm.classifyDocument
is sorted ascendant
-------------------------------------------------------------------------------------------------
Key: MAHOUT-605
URL: https://issues.apache.org/jira/browse/MAHOUT-605
Project: Mahout
Issue Type: Bug
Components: Classification
Affects Versions: 0.4
Environment: Linux
Reporter: Robin Swezey
Priority: Minor
Fix For: 0.4
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)
