A study by Alice O'Toole and Jacqueline Cavazos of the University of Texas at Dallas (UT Dallas) named the underlying factors that engender racial bias in facial recognition technology.
O'Toole said different mechanisms contribute to biases; Cavazos categorized contributing factors as either data-driven (affecting the algorithm’s performance) or operationally defined (stemming from user input).
O'Toole noted a reduction in training image quality makes racial bias more pronounced, while Cavazos said operational bias can be introduced based on where the threshold is set between matching and nonmatching decisions, and on what types of paired images are selected.
Said O'Toole, "We have learned so much about the complexity of the problem that we have to acknowledge that there may never be a solution to the problem of making every face equally challenging to a face recognition algorithm."
