Hi Aslan, You can check out the unittest code of GradientDescent.runMiniBatchSGD https://github.com/apache/spark/blob/master/mllib/src/test/scala/org/apache/spark/mllib/optimization/GradientDescentSuite.scala Sincerely, DB Tsai --- My Blog: https://www.dbtsai.com LinkedIn: https://www.linkedin.com/in/dbtsai On Sat, Jun 7, 2014 at 6:24 AM, Aslan Bekirov wrote: > Hi All, > > I have to create a model using SGD in mlbase.

Gradient Descent with MLBase
Hi All, I have to create a model using SGD in mlbase. I examined a bit mlbase and run some samples of classification , collaborative filtering etc.. But I could not run Gradient descent. I have to run "val model = GradientDescent.runMiniBatchSGD(params)" of course before params must be computed. I tried but could not managed to give parameters correctly. Can anyone explain parameters a bit and give an example of code? BR, Aslan
