<p>I guess sparse_autoencoder_test_2.cpp is the modified test and we can remove the sparse_autoencoder_test.cpp file and rename the other test.</p>

<p>I would like to do that too, but the problem is old sparseAutoencoder and the new one do not have the same api, so the tests need to have some change. </p>
