Please add examples for linear and non-linear regression in
incubator-mxnet/scala-package/examples/src/main/scala/org/apache/mxnetexamples/

Currently, there is no example for scala, how to use linear regression.

That is a good suggestion @KaizerF. For the moment, you could try taking a look at the python examples. The python and Scala APIs are very similar and it should correspond fairly closely to what you would need to do in Scala.
