  报告题目:Adversarial Machine Learning: an intruduction and tutorial

  报告摘要:Deep learning has become increasingly popular in the past few years. This is largely attributed to a family of powerful models called deep neural networks (DNNs). With many stacked layers, and millions of neurons, DNNs are capable of learning complex non-linear mappings, and have demonstrated near or even surpassing human-level performance in a wide range of applications such as image classification, object detection, natural language processing, speech recognition self-driving cars,playing games or medical diagnosis. Despite their great success, DNNs have recently been found vulnerable to adversarial examples (or attacks), which are input instances slightly modified in a way that is intended to fool the model. Such a surprising weakness of DNNs has raised security and reliability concerns on the development of deep learning systems in safety-critical scenarios such as face recognition, autonomous driving and medical diagnosis. Since the first discovery, this has attracted a huge volume of work on either attacking or defending DNNs against these attacks. In this tutorial, we will introduce this adversarial phenomenon, explanations to this phenomenon, and techniques that have been developed for both attack and defense.
