Abstract:

We are entering an exciting era where human intelligence is being enhanced by machine intelligence through big data fueled artificial intelligence (AI) and machine learning (ML). However, recent work shows that prediction models trained privately are vulnerable to adversarial examples and privacy invasion, both of which turn AI and ML against itself through inference attacks and both maliciously manipulate the prediction outputs with only a black box access to a machine learning as a service API. We argue that the trustworthiness should be an essential and mandatory component of a deep learning system for algorithmic decision making. This includes (1) the understanding and the measurement of the level of trust and/or distrust that we place on a deep learning algorithm to perform reliably and truthfully, and (2) the development of formal metrics to formally and quantitatively evaluate and measure the trust level of an algorithmic decision making result by examining the trustworthiness of the algorithm with respect of intentional and unintentional effects of execution, in the presence of different adversarial settings. In this talk, I will share some of our empirical results and characterization on trust and privacy of deep learning in adversarial settings.
