Abstract
Despite notable successes on several carefully controlled benchmarks, current machine learning (ML) systems are remarkably brittle, raising serious concerns about their deployment in safety-critical applications like self-driving cars and predictive healthcare. In this talk, I discuss fundamental obstacles to building robust ML systems and develop principled approaches that form the foundations of robust ML. I will focus on two settings where standard ML models degrade substantially: adversarial attacks on test inputs, and presence of spurious correlations like image backgrounds. I will demonstrate the need to question common assumptions in ML, particularly about the role of training data. On the one hand, I will describe how and why naively using more data can surprisingly hurt performance in these robustness settings. On the other hand, I will show that unlabeled data, when harnessed in the right fashion, is extremely beneficial and enables state-of-the-art robustness. In closing, I will discuss how to build on the foundations of robust ML and achieve wide-ranging robustness in various domains including natural language processing and vision.
Biography
Aditi Raghunathan is a fifth year PhD student at Stanford University advised by Percy Liang. She is interested in building robust machine learning systems with guarantees for trustworthy real-world deployment. Her research in robustness has been recognized by a Google PhD Fellowship in Machine Learning and the Open Philanthropy AI Fellowship. Among other honors, she is also the recipient of the Anita Borg Memorial Scholarship and the Stanford School of Engineering Fellowship.

Abstract
We give a 2-pass semi-streaming algorithm to find the exact global minimum cut of an unweighted, undirected graph. This result is adapted from a paper by Aviad Rubinstein, Tselil Schramm, and S. Matthew Weinberg called Computing Exact Minimum Cuts Without Knowing the Graph (ITCS 2018).

Abstract
Mental health problems such as anxiety disorders and depression have grown in the last decades, with a huge increase in the rate of growth for people under age 26 since the early years of smartphone adoption. Depression is on track to be the global #1 disease burden by 2030. To date, doctors do not understand what causes or precipitates depression, or how to forecast it; nor is there a reliable treatment, although most people will get better. Mobile and wearable devices are improving in their ability to model continuous physiology and activity/sleep/social data for detecting subtly changing patterns related to changing health, and providing early AI-generated forecasts of changes in health. What are some of these patterns telling us about neurological activity, mood, stress and brain health and how accurately? This talk will highlight some of the latest results from our studies at MIT, focusing on both scientific and ethical challenges in using AI to foster good mental health.
Biography
Dr. Rosalind Picard, MIT and Empatica. Dr. Picard is a professor, inventor, engineer, and scientist. She wrote the book Affective Computing that outlines how to give machines the skills of emotional intelligence, which inspired the growing field of Affective Computing. She co-founded two companies that commercialized inventions by her and her team at MIT: Empatica, providing the first AI-smartwatch recognized by the FDA for monitoring seizures, and Affectiva, providing emotion AI software. At MIT, she is a full professor teaching and directing research at the Media Lab, and serves as founding faculty chair for MindHandHeart, MIT’s campus-wide wellbeing initiative. She serves also as chief scientist and Chairman for Empatica, where working with many medical partners, they recently released the first medically approved (in the EU) non-invasive smartwatch running AI for forecasting a positive PCR test for a viral respiratory infection (Influenza H1N1, Rhinovirus, or COVID-19).
