Segmentation with mixed supervision: Confidence maximization helps knowledge distillation

2 code implementations21 Sep 2021 Bingyuan Liu, Christian Desrosiers, Ismail Ben Ayed, Jose Dolz

Combined with a standard cross-entropy loss over the labeled pixels, our novel formulation integrates two important terms: (i) a Shannon entropy loss defined over the less-supervised images, which encourages confident student predictions in the bottom branch; and (ii) a KL divergence term, which transfers the knowledge (i. e., predictions) of the strongly supervised branch to the less-supervised branch and guides the entropy (student-confidence) term to avoid trivial solutions.

Do We Really Need Dice? The Hidden Region-Size Biases of Segmentation Losses

1 code implementation18 Apr 2021 Bingyuan Liu, Jose Dolz, Adrian Galdran, Riadh Kobbi, Ismail Ben Ayed

Most segmentation losses are arguably variants of the Cross-Entropy (CE) or Dice losses.

Improving Neural Network Robustness through Neighborhood Preserving Layers

no code implementations28 Jan 2021 Bingyuan Liu, Christopher Malon, Lingzhou Xue, Erik Kruus

Finally, we empirically show that our designed network architecture is more robust against state-of-art gradient descent based attacks, such as a PGD attack on the benchmark datasets MNIST and CIFAR10.
