SystemDS-NN Tests

This folder contains tests for the SystemDS-NN (nn) deep learning library.

Tests

All layers are tested for correct derivatives (“gradient-checking”), and many layers also have correctness tests against simpler reference implementations.

• grad_check.dml - Contains gradient-checks for all layers as individual DML functions.
• test.dml - Contains correctness tests for several of the more complicated layers by checking against simple reference implementations, such as conv_simple.dml. All tests are formulated as individual DML functions.
• run_tests.dml - A DML script that runs all of the tests in grad_check.dml and test.dml.

Execution

• spark-submit SystemDS.jar -f nn/test/run_tests.dml from the base of the project.
