Abstract:  

Intelligent machines are poised to transform the human experience. On the one hand, these machines (such as robots, autonomous vehicles, and digital assistants) hold an enormous potential to enhance human capabilities. On the other hand, without purposeful emphasis on their interaction with humans, they can lead to adverse side effects – ranging from operational inefficiencies to fatal accidents. The goal of my research is to realize the potential of intelligent machines by addressing foundational challenges of human-machine interaction.

In this talk, I will ground these challenges in the context of human-robot collaboration. Traditionally, robots have excelled in structured settings, such as safety cages in factories. In my research, I have designed robots that can operate beyond these structured settings and collaborate with humans in dynamic environments. I will present the models and algorithms that are central to designing these collaborative robots. First, I will discuss the need for modeling human behavior and present an approach, termed Constrained Variational Inference, to learn behavioral models with limited data and high-level manual input. Next, I will describe planning algorithms that allow robots to make decisions at execution-time and with partial information. In collaboration with industry partners, I have deployed robots to assist humans in the final assembly of cars. Based on this experience, I will illustrate that the models and algorithms for interaction not only maintain safety but also improve the efficiency of human-robot collaboration.

Finally, I will discuss future directions – which include designing human-in-the-loop learning algorithms and enabling transparency in machine’s decision-making – to realize the potential of interactive intelligent machines across domains.
