[jira] [Updated] (SYSTEMML-1005) MultiLogReg Test Failure: Invalid
input w/ zeros for rexpand ignore=false (rlen=1617, nnz=1455).

Mike Dusenberry updated SYSTEMML-1005:
--------------------------------------
Description:
Currently, the {{test_mllearn.py -> TestMLLearn.testLogisticSK1}} test is failing with the following error:

Basically, this test case directly creates {{MatrixBlocks}} and supplies them as input the {{LogisticRegression}} Scala wrapper we have, which in turn calls {{MultiLogReg.dml}}.
Within {{MultiLogReg.dml}}, the {{Y_vec}} input is converted from a vector of class labels to a matrix of one-hot encoded labels. During this conversion, the {{Y_vec}} vector is first transformed to have class labels <= 0 be converted to be the largest labels. Thus, this updated {{Y_vec}} matrix has no zero values. This updated {{Y_vec}} vector is then passed into the {{table}} function to be one-hot encoded. At this point, it checks if {{Y_vec}} has any zero values based on the {{nnz}} of the {{MatrixBlock}}, and in this case fails because the {{nnz}} of {{Y_vec}} is still erroneously set to the previous {{nnz}} from before the above transformation for class labels <= 0.
Interestingly, if we remove the recent update to {{MultiLogReg.dml}} from SYSTEMML-958, [https://github.com/apache/incubator-systemml/commit/10dff5c9e3eb737a965846246d8187fcb0b03689], the test passes. Regardless, this is a bug as the {{nnz}} should be updated after {{Y_vec}} is transformed to have no 0 values.
