Andrew Palumbo updated MAHOUT-1564:
-----------------------------------
Fix Version/s: 0.10.1
> Naive Bayes Classifier for New Text Documents
> ---------------------------------------------
>
> Key: MAHOUT-1564
> URL: https://issues.apache.org/jira/browse/MAHOUT-1564
> Project: Mahout
> Issue Type: Improvement
> Affects Versions: 0.9
> Reporter: Andrew Palumbo
> Assignee: Andrew Palumbo
> Labels: DSL, legacy, scala, spark
> Fix For: 0.10.1, 0.10.0
>
>
> MapReduce and DSL Naive Bayes implementations currently lack the ability to
> classify a new document (outside of the training/holdout corpus). This New
> feature will do the following.
> 1. Vectorize a new text document using the dictionary and document
> frequencies from the training/holdout corpus
> - assume the original corpus was vectorized using `seq2sparse`; step (1)
> will use all of the same parameters.
> 2. Score and label a new document using a previously trained model.
> This effort will need to be done in parallel for MRLegacy and DSL
> implementations. Neither should be too much work.
