Explainable Group Decision-Making for Explainable Machine Learning


Ethical machine learning researchers have established that algorithmic decision-making encodes biases and preferences from training data into the features and weights used in future predictions. The high stakes of today’s algorithmic tools have led to a call for interpretability and accountability, demanding algorithms that can explain the reasons that led to an automated decision and assign responsibility for those judgments. In this work I go further, showing that trained models can make visible the complex human discourse processes that led to a dataset’s outcomes in the first place. Using Wikipedia’s Articles for Deletion as a case study, I show that we can describe how debates are won and lost online, and discuss how that impacts explainability research. I will also describe the 14-year historical corpus that we collected for this research, which we release for open use by the broader social computing community.
