Adversarial Attack Generation Empowered by Min-Max Optimization

NeurIPS 2021poster

The worst-case training principle that minimizes the maximal adversarial loss, also known as adversarial training (AT), has shown to be a state-of-the-art approach for enhancing adversarial robustness. Nevertheless, min-max optimization beyond the purpose of AT has not been rigorously explored in th…

Scalability vs. Utility: Do We Have To Sacrifice One for the Other in Data Importance Quantification?

CVPR 2021poster

Quantifying the importance of each training point to a learning task is a fundamental problem in machine learning and the estimated importance scores have been leveraged to guide a range of data workflows such as data summarization and domain adaption. One simple idea is to use the leave-one-out err…
