Angel Martinez Gonzalez updated MAHOUT-775:
-------------------------------------------
Attachment: MAHOUT-775.patch
The problem is that the L2 variance ("s" member)is initialized with a 0 value.
As regularization is controlled by AdaptiveLogisticRegression through the
"lambda" hyperparameter, I think a value of 1 would be ok for "s". Also, a
variance of 0 does never make sense, so I modified the constructor of L2.
See attached patch.
