Leveraging Sparse Linear Layers for Debuggable Deep Networks
Proceedings of the 38th International Conference on Machine Learning, PMLR 139:11205-11216, 2021.
We show how fitting sparse linear models over learned deep feature representations can lead to more debuggable neural networks. These networks remain highly accurate while also being more amenable to human interpretation, as we demonstrate quantitatively and via human experiments. We further illustrate how the resulting sparse explanations can help to identify spurious correlations, explain misclassifications, and diagnose model biases in vision and language tasks.
