Subject [GitHub] spark issue #16784: [SPARK-19382][ML]:Test sparse vectors in LinearSVCSuite
Date Tue, 28 Feb 2017 19:34:51 GMT

    @jkbradley I simplified the test cases and modified the data generation API using to toSparse
method, which eliminates the index variable. 
    "Is this multivariate online summarizer issue really a bug? Or is it from passing in sparse
vectors which are 10x longer than the dense vectors?"
    I think it is not a bug, which is due to the different sizes between dense and sparse
vectors. It means that we can't mix using the two together.
