Hi Xiangrui, Thank you for the reply! I have tried customizing LogisticRegressionSGD.optimizer as in the example you mentioned, but the source code reveals that the intercept is also penalized if one is included, which is usually inappropriate. The developer should fix this problem.

"examples/src/main/scala/org/apache/spark/examples/mllib/BinaryClassification.scala" contains example code that shows how to set regParam. 2. A static method with more than 3 parameters becomes hard to remember and hard to maintain. Please use LogistricRegressionWithSGD's default constructor and setters. -Xiangrui
