Training neural networks is not generally deterministic, but not for the reasons you mention. Neural networks are trained on data, but start with a random initializations. This random initialization can lead to different trained networks even when two networks are trained with the same data on the same machine. A test suite should be robust enough to handle the variations in trained nets (linear functions may be more repeatable, and adequate for architecture and basic testing purposes). DanVK
