A Framework for Quality Assurance of Machine Learning Applications

Murphy, Christian; Kaiser, Gail E.; Arias, Marta

Some machine learning applications are intended to learn properties of data sets where the correct answers are not already known to human users. It is challenging to test and debug such ML software, because there is no reliable test oracle. We describe a framework and collection of tools aimed to assist with this problem. We present our findings from using the testing framework with three implementations of an ML ranking algorithm (all of which had bugs).
