[jira] [Updated] (MAHOUT-1263) Serialise/Deserialise Lambda value for OnlineLogisticRegression
[ https://issues.apache.org/jira/browse/MAHOUT-1263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Mike Davy updated MAHOUT-1263: -- Attachment: MAHOUT-1263.patch 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 Labels: patch Attachments: MAHOUT-1263.patch Original Estimate: 0.5h Remaining Estimate: 0.5h 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.
