Deception, Robustness and Trust in Big Data Fueled Deep Learning Systems

Ling Liu, Professor, School of Computer Science, Georgia Institute of Technology, USA

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 DNN models trained privately are vulnerable to adversarial inputs. Such adversarial inputs inject small amount of perturbations to the input data to fool machine learning models to misbehave, turning a deep neural network against itself. As new defense methods are proposed, more sophisticated attack algorithms are surfaced. This arms race has been ongoing since the rise of adversarial machine learning. This keynote provides a comprehensive analysis and characterization of the most representative attacks and their defenses. As more and more mission critical systems are incorporating machine learning and AI as an essential component in their real-world big data applications and their big data service provisioning platforms or products, understanding and ensuring the verifiable robustness of deep learning becomes a pressing challenge in the presence of adversarial attacks. This includes (1) the development of formal metrics to quantitatively evaluate and measure the robustness of a DNN prediction with respect of intentional and unintentional artifacts and deceptions, (2) the comprehensive understanding of the blind spots and the invariants in the DNN trained models and the DNN training process, and (3) the statistical measurement of trust and distrust that we can place on a deep learning algorithm to perform reliably and truthfully. In this keynote talk, I will use empirical analysis and evaluation of our cross-layer strategic teaming defense framework and techniques to illustrate the feasibility of ensuring robust deep learning.

Currently Prof. Liu is co-PC chair of The Web 2019 (WWW 2019) and the Editor in Chief of ACM Transactions on Internet Technology (TOIT). Prof. Liu’s research is primarily sponsored by NSF, IBM and Intel.

The new science of cause and effect, with reflections on data science and artificial intelligence

Judea Pearl, Chancellor Professor, Departments of Computer Science and Statistics, University of California, Los Angeles, USA

Abstract: The past three decades have seen the development of powerful tools for modeling and computing causal relationships which may have major impact on data science. My talk will illustrate how these tools work in seven tasks:
1. Encoding causal assumptions in transparent and testable way
2. Predicting the effects of actions and policies
3. Computing counterfactuals and finding causes of effects
4. Computing direct and indirect effects (Mediation)
5. Integrating data from diverse sources.
6. Recovering from missing data
7. Discovering causal relations from data
A friendly, non technical account of these ideas is available in: "The Book of Why: the new science of cause and effect," Judea Pearl and Dana MacKenzie,(Basic Books, 2018).

Prof. Judea Pearl is Chancellor professor of computer science and statistics at UCLA, where he directs the Cognitive Systems Laboratory and conducts research in artificial intelligence, human reasoning, and philosophy of science. He has authored hundreds of researche papers and three books: Heuristics (1983), Probabilistic Reasoning (1988) and Causality (2000, 2009) which won of the London School of Economics Lakatos Award in 2002. More recently, he co-authored Causal Inference in Statistics (2016, with M. Glymour and N. Jewell) and "The Book of Why" (2018, with Dana Mackenzie) which introduces causal analysis to a general audience. Pearl is a member of the National Academy of Sciences the National Academy of Engineering, a fellow of the IEEE, the Cognitive Science Society and the Association for the Advancement of Artificial Intelligence. In 2012, he won the Technion's Harvey Prize and the ACM Alan Turing Award "for fundamental contribution to artificial intelligence through the development of a calculus for probabilistic and causal reasoning."
