Uncertainty in objectives

It is reasonable to expect that AI capabilities will eventually exceed those of humans across a range of real-world-decision making scenarios. Should this be a cause for concern, as Elon Musk, Stephen Hawking, and others have suggested? While some in the mainstream AI community dismiss the issue, I will argue instead that a fundamental reorientation of the field is required. Instead of building systems that optimize arbitrary objectives, we need to learn how to build systems that will, in fact, be beneficial for us. I will show that it is useful to imbue systems with explicit uncertainty concerning the true objectives of the humans they are designed to help. This uncertainty causes machine and human behavior to be inextricably (and game-theoretically) linked, while opening up many new avenues for Research.

Bigger data about smaller people: Studying children’s language learning at scale

How do children acquire language? Decades of work have provided a roadmap of principles and mechanisms for early language learning as attested by small-scale laboratory tasks. But there is not yet a convincing empirical synthesis of this work that addresses both the systematicity and ubiquity of language learning and the variability of learning trajectories across children. In this talk I will describe some initial steps towards such a synthesis. This research integrates high-density data from individual children learning a single language and summary data from tens of thousands of children learning more than a dozen languages. Taken together, the data support a hybrid picture in which children slowly accumulate knowledge in rich social contexts but also show evidence for surprisingly fast grammatical abstractions. Further, this work illustrates our approach to creating interfaces that allow for easy interactive and programmatic access to large developmental datasets.

Michael C. Frank is Associate Professor of Psychology at Stanford University. He earned his BS from Stanford University in Symbolic Systems in 2005 and his PhD from MIT in Brain and Cognitive Sciences in 2010. He studies both adults' language use and children's language learning and how both of these interact with social cognition. His work uses behavioral experiments, computational tools, and novel measurement methods including large-scale web-based studies, eye-tracking, and head-mounted cameras. He has been recognized as a "rising star" by the Association for Psychological Science. His dissertation received the Glushko Prize from the Cognitive Science Society, and he is recipient of the FABBS Early Career Impact award and the Klaus W. Jacobs Advanced Research Fellowship. He has served as Associate Editor for the journal Cognition, member and chair of the Governing Board of the Cognitive Science Society, and was a founding Executive Committee member of the Society for the Improvement of Psychological Science.

Reproducibility, Reusability, and Robustness in Deep Reinforcement Learning

In recent years, significant progress has been made in solving challenging problems across various domains using deep reinforcement learning. However reproducing results for state-of-the-art deep RL methods is seldom straightforward. High variance of some methods can make learning particularly difficult when environments or rewards are strongly stochastic. Furthermore, results can be brittle to even minor perturbations in the domain or experimental procedure. In this talk, I will discuss challenges that arise in experimental techniques and reporting procedures in deep RL, and will suggest methods and guidelines to make future results more reproducible, reusable and robust. I will also report on findings from the ICLR 2018 reproducibility challenge.

A Future with Affordable Self-driving Vehicles

We are on the verge of a new era in which robotics and artificial intelligence will play an important role in our daily lives. Self-driving vehicles have the potential to redefine transportation as we understand it today. Our roads will become safer and less congested, while parking spots will be repurposed as leisure zones and parks. However, many technological challenges remain as we pursue this future.
In this talk I will showcase the latest advancements made by Uber Advanced Technologies Group's Research Lab in the quest towards self-driving vehicles. In addition, you'll hear my thoughts on the future of research and education in this field, where both industry and academia come together to form the next generation of students and solve the remaining open research problems.
