How explainable are adversarially-robust CNNs?

no code implementations25 May 2022 Mehdi Nourelahi, Lars Kotthoff, Peijie Chen, Anh Nguyen

Here, we perform the first, large-scale evaluation of the relations of the three criteria using 9 feature-importance methods and 12 ImageNet-trained CNNs that are of 3 training algorithms and 5 CNN architectures.

FlexiBO: A Decoupled Cost-Aware Multi-Objective Optimization Approach for Deep Neural Networks

1 code implementation18 Jan 2020 Md Shahriar Iqbal, Jianhai Su, Lars Kotthoff, Pooyan Jamshidi

FlexiBO weights the improvement of the hypervolume of the Pareto region by the measurement cost of each objective to balance the expense of collecting new information with the knowledge gained through objective evaluations, preventing us from performing expensive measurements for little to no gain.
