Shortcuts are decision rules that perform well on standard benchmarks but fail to transfer to more challenging testing conditions, such as real-world scenarios. This can happen when the algorithm learns to use spurious correlations to perform the prediction task. For example, an algorithm learned how to detect pneumonia from chest X-rays by detecting which hospital the scan came from using the labels on the photos [1]. In this project, we develop strategies to prevent shortcut learning in medical applications [2].
