Hey, I've been trying out mahout-228: Sequential LR (using SGD). Few things I haven't been able to figure out:
1. Is there a parallel version? Can it integrate with hadoop and do each pass in parallel? 2. Weighting - is there support for weighted samples? E.g. I have 50 doughnuts with the same predictors and the same target color, must I feed 50 rows to OnlineLogisticRegression, isn't there a way to feed one line with a weight of 50? 3. Is it possible to define a stop condition instead of explicitly setting the number of passes. E.g. stop when the Fisher test reaches a certain value? Thanks, and my apologies if these are really obvious Ido -- View this message in context: http://lucene.472066.n3.nabble.com/Newbie-questions-about-Mahout-228-Logistic-Regression-LR-SGD-tp977968p977968.html Sent from the Mahout User List mailing list archive at Nabble.com.
