DPA: A one-stop metric to measure bias amplification in classification datasets
Published in NeurIPS, 2025
Most ML datasets today contain biases. When we train models on these datasets, they often not only learn these biases but can worsen them — a phenomenon known as bias amplification. We propose a better metric to measure bias amplification.
