Description of the Tutorial

Adversarial machine learning (AdvML) is one of the most rapidly growing research fields in machine learning (ML) and artificial intelligence (AI). It studies adversarial robustness of state-of-the-art ML models such as neural networks, spanning from attacks that identify limitations of current ML systems, defenses that strengthen the model performance against various adversarial threats, to verification tools that quantify the level of robustness for different applications.

Beyond the recent advances in AdvML, this tutorial aims to provide fresh aspects on “what’s next in AdvML”, i.e., adversarial machine learning for good. The phrase “for good” has two-fold meanings – novel innovations and sustainability. First, this tutorial will introduce emerging and novel applications that leverage the lessons from AdvML to benefit mainstream ML tasks, which differ from the original objective of evaluating and improving adversarial robustness. The examples include (i) generating contrastive explanations and counterfactual examples; (ii) model reprogramming for data-efficient transfer learning; (iii) model watermarking and fingerprinting for AI governance and ownership regulation; and (iv) data cloaking for enhanced privacy. Second, with the explosive number of submissions related to adversarial robustness growing every year, this tutorial aims to discuss the sustainability of this young research field towards continuous and organic growth, in terms of research norms and ethics, current trends, open challenges, and future directions. The target audience will be ML/AI researchers who are familiar with AdvML, as well as researchers who are interested in entering this field. The speaker will also share his thoughts from industrial practices.

Tutorial Outline

Unlike conventional tutorials on adversarial machine learning (AdvML) that focus on adversarial attacks, defenses, or verification methods, this tutorial aims to provide a fresh overview of how the same technique can be used in totally different manners to benefit mainstream machine learning tasks and to facilitate sustainable growth in this research field. This tutorial will start by reviewing the recent advances in AdvML and then delve into novel innovations to other domains (beyond adversarial robustness) inspired from AdvML. In particular, we will cover several noteworthy innovations proposed in recent years and relate their success to AdvML, including (i) generation of contrastive explanations and counterfactual examples; (ii) model reprogramming for data-efficient transfer learning; (iii) model watermarking and fingerprinting for AI governance and ownership regulation; (iv) data cloaking for enhanced privacy; and (v) data augmentation for improving model generalization. Finally, this tutorial will discuss the sustainability of this research field towards continuous and organic growth, in terms of research norms and ethics, current trends, open challenges, and future directions.

The outline of the tutorial is listed as follows.
