Summary: Improve output size calculation in conv2d & max_pool2d
Key: SYSTEMML-1516
URL: https://issues.apache.org/jira/browse/SYSTEMML-1516
Project: SystemML
Issue Type: Sub-task
Reporter: Mike Dusenberry
Assignee: Mike Dusenberry
Priority: Minor
The calculation of the output sizes (`Hout`, `Wout`) for conv2d and
max_pool2d layers rely on a flooring operation to only allow for valid
operations. Currently, we simply rely on the `as.integer` call to
implicitly perform this flooring operation during truncation of the double
to an integer. While this gives the correct results, it is less
readable than it should be, and relies on truncation behavior than explicit
mathematical behavior. We should simply add an explicit `floor`
operation to each calculation.
