---------------------------------
Summary: Serialise/Deserialise Lambda value for
OnlineLogisticRegression
Key: MAHOUT-1263
URL: https://issues.apache.org/jira/browse/MAHOUT-1263
Project: Mahout
Issue Type: Bug
Components: Classification
Affects Versions: 0.7
Reporter: Mike Davy
The value for Lambda in OnlineLogisticRegression seems not the be
serialised/deserialised correctly.
If I train a model with a specific lambda value, serialise it, then read it
back in, the value of Lambda goes back to the default value (1.0e-5).
I've created a patch that adds the lambda value into the write/readFields
(org.apache.hadoop.io.Writable). Patch includes a unit test that checks the
values after serialising/deserialising to/from a ByteArray.
I think this is correct, unless I'm missing something obvious?
