Subject Re: Hadoop LR comparison

Hi Li-Ming,

This binary logistic regression using SGD is in
https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/classification/LogisticRegression.scala

We're working on multinomial logistic regression using Newton and L-BFGS
optimizer now. Will be released soon.


Sincerely,
