Sparse API is still in the queue of our TODO list. We will try to get this set of APIs release in the next few months. If you can't wait and would like to 'unlock' this feature to try on your own, please change it here:
https://github.com/apache/incubator-mxnet/blob/master/scala-package/macros/src/main/scala/org/apache/mxnet/SymbolMacro.scala#L60#L63
or here if you prefer type-checked api:
https://github.com/apache/incubator-mxnet/blob/master/scala-package/macros/src/main/scala/org/apache/mxnet/SymbolMacro.scala#L94#L98
Just allow 'sparse' as an accepted input. There is no guarantee that this API will fully worked as we haven't test that.

interested as well, as this is key to our adoption of MXNet (we're heavy user of sparse computations)
