https://github.com/fommil/matrix-toolkits-java has a bunch of sparse stuff in it. Check out the references to the "Sparse Storage" in the README. LinkedSparseMatrix has served me well over the years for unstructured sparse matrices but there are no silver bullets. I don't know much about Spark's Sparse representations, but in my experience the kind of sparsity is what really matters. -- This is an automated message from the Apache Git Service.
