Key: MAHOUT-674
URL: https://issues.apache.org/jira/browse/MAHOUT-674
Project: Mahout
Issue Type: Improvement
Components: Examples
Affects Versions: 0.4, 0.5
Environment: Mac OS X 10.6.7
Reporter: Stanley Xu
Priority: Trivial
Fix For: 0.5
In the example of trainlogistic, if we add a category feature. It will throw a
NullPointerException while printing out the model.
The root cause is for category feature, the code try to use the feature name as
the predictor rather than feature=value as the predictor while get the weight
from the trained LR model.
