Not too many people aspired to be a 'tester to a machine learning system' when I was in school. But it's a job today in a field that's likely to grow tomorrow. It's not simply a matter of making sure the AI got the answer right. "To ensure quality, it's important to test learned logic. So I asked myself, how do I test this learning process and the logic learnt by the model? Is it even possible to test this logic? Is a model completely a black box?" This article describes (to some degree) how machine learning works and the various permutations of testing that allow assessors to evaluate validity.
