Summary: More efficient SparseMatrix.equals
Key: SPARK-10906
URL: https://issues.apache.org/jira/browse/SPARK-10906
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Joseph K. Bradley
Priority: Minor
SparseMatrix.equals currently uses toBreeze and then calls Breeze's equals
method. However, it looks like Breeze's equals is inefficient:
[https://github.com/scalanlp/breeze/blob/1130e0de31948d19225179d8500a8d2d1cc337d0/math/src/main/scala/breeze/linalg/Matrix.scala#L132]
Breeze iterates over all values, including implicit zeros. We could make this
more efficient.
