A Systematic Study of Bias Amplification

Hall, Melissa, van der Maaten, Laurens, Gustafson, Laura et al.

Understand

Recent research suggests that predictions made by machine-learning models can amplify biases present in the training data.

  • When a model amplifies bias, it makes certain predictions at a higher rate for some groups than expected based on training-data statistics.
  • Mitigating such bias amplification requires a deep understanding of the mechanics in modern machine learning that give rise to that amplification.
  • We perform the first systematic, controlled study into when and how bias amplification occurs.
