Modern machine learning (ML) offers a new way of creating software to solve problems, focused on learning structures, learning algorithms, and data. In all steps of this process, from the specification of the problem, to the datasets chosen as relevant to the solution, to the choice of learning structures and algorithms, a variety of biases can creep in and compound each other. In this talk, we present a systems view of detecting Bias in AI/ML systems as analogous to the software testing problem. To start, a variety of expectations from an AI/ML system can be specified given its intended goals and deployment. Different kinds of bias can then be mapped to different failure modes, which can then be tested for during a variety of techniques. We will also describe a new technique based on Topological Data Analysis to detect bias in source datasets. This technique utilizes a persistence homology based visualization and is lightweight: the human-in-the-loop does not need to select metrics or tune parameters, and carry out this step before choosing a model. We’ll describe experiments on the German credit dataset using this technique to demonstrate its effectiveness.
