Matthias Boehm commented on SYSTEMML-2121:
------------------------------------------
great - I extended the description accordingly. I would recommend to start with
PCA.
> Add missing algorithm tests to codegen testsuite

> Key: SYSTEMML-2121
> URL: https://issues.apache.org/jira/browse/SYSTEMML-2121
> Project: SystemML
> Issue Type: Technical task
> Reporter: Matthias Boehm
> Priority: Major
>
> There are several algorithms in {{scripts/algorithms}} that are not covered
> by the algorithm-level tests in
> {{org.apache.sysml.test.integration.functions.codegenalg}} yet. This includes
> algorithms such as descriptive statistics, decision trees, PCA/PPCA, survival
> analysis, and data generation scripts. Accordingly, this task aims to add
> algorithm tests that directly refer to the dml scripts in
> {{scripts/algorithms}} and add the related R script. For complex algorithm
> where this conversion to R scripts would require large effort, we should at
> least run the dml script to ensure codegen works properly.
