Hi Sourigna,
it turned out to be a bug in the GradientDescent implementation which
cannot handle sparse gradients. That is not so problematic by itself,
because the sum of gradient vectors is usually dense even if the individual
gradient vectors are sparse. We simply forgot to initialize the initi
Hi Gna,
Thanks for reporting the problem. Because level 1 operation in FlinkML BLAS
library doesn’t support SparseVector, SparseVector is not supported currently.
I’ve filed this to JIRA [1].
Maybe I can send a patch to solve this in few days.

All:
I'm trying to use SparseVectors with FlinkML 0.10.1. It does not seem to
be working. Here is a UnitTest that I created to recreate the problem:
*package* com.aol.ds.arc.ml.poc.flink
> *import* org.junit.After
> *import* org.junit.Before
> *import* org.slf4j.LoggerFactory
> *import* org.
