Matthias Boehm updated SYSTEMML-2030:
-------------------------------------
Description: For example, on L2SVM 800GB sparse, there are various examples
of {{t(X) mm y}} where we do not apply the transpose-matrix mult rewrite to
{{t(t( y ) mm X)}} because the matrix mult is of type CP whereas the transpose
is of type Spark. (was: For example, on L2SVM 800GB sparse, there are various
examples of {{t(X) mm y}} where we do not apply the transpose-matrix mult
rewrite to {{t(t(y) mm X)}} because the matrix mult is of type CP whereas the
transpose is of type Spark.)
