Saliency is a Possible Red Herring When Diagnosing Poor Generalization

1 code implementation ICLR 2021 Joseph D. Viviano, Becks Simpson, Francis Dutil, Yoshua Bengio, Joseph Paul Cohen

In some prediction tasks, such as for medical images, one may have some images with masks drawn by a human expert, indicating a region of the image containing relevant information to make the prediction.

Underwhelming Generalization Improvements From Controlling Feature Attribution

no code implementations25 Sep 2019 Joseph D Viviano, Becks Simpson, Francis Dutil, Yoshua Bengio, Joseph Paul Cohen

We describe a simple method for taking advantage of such auxiliary labels, by training networks to ignore the distracting features which may be extracted outside of the region of interest, on the training images for which such masks are available.

Deep neural network or dermatologist?

1 code implementation19 Aug 2019 Kyle Young, Gareth Booth, Becks Simpson, Reuben Dutton, Sally Shrapnel

We show that despite high accuracy, the models will occasionally assign importance to features that are not relevant to the diagnostic task.

GradMask: Reduce Overfitting by Regularizing Saliency

no code implementations16 Apr 2019 Becks Simpson, Francis Dutil, Yoshua Bengio, Joseph Paul Cohen

With too few samples or too many model parameters, overfitting can inhibit the ability to generalise predictions to new data.
