Title: “Machine Learning Methods for Real-time Control with Theoretical Guarantees”
Today, many would like to deploy robots everywhere: in the streets, as cars, wheelchairs, and other mobility devices; in our homes, to cook, clean, and entertain us; on the body, to replace a lost limb or to augment its capabilities. For these robots to become reality, they need to depart from their ancestors in one dramatic way: They must escape from the comfortable, secluded, and largely predictable industrial world. In the past decades, robotics has made leaps forward in the design of increasingly complex robotic platforms to meet these challenges. In this endeavor, it has benefited from advances in optimization for solving high-dimensional constrained problems. These methods are powerful for planning in slow-paced tasks and when the environment is known. Advances in machine learning (ML) to analyze vast amounts of data often have offered powerful solutions for real-time control, but they often fall short of providing explicit guarantees on the learned model.
This talk will give an overview of a variety of methods to endow robots with the necessary reactivity to adapt their path at time-critical situations. Online reactivity is not just a matter of ensuring that there is a good-enough central processing unit (CPU) on board the robot. It requires inherently robust control laws that can provide multiple solutions. We will see methods by which robots can learn control laws from only a handful of examples, while generalizing to the entire state space. The learned control laws are accompanied by theoretical guarantees for stability and boundedness. The methods combine planning and ML to learn feasible control laws, retrievable at run time with no need for further optimization. The talk is largely based on our Textbook and its accompanying video and coding examples:

Title: “Towards Scalable Autonomy”
Training autonomous agents and systems that perform complex tasks in a variety of real-work environments remains a challenge. While reinforcement learning is a promising technique, training RL agents is an expensive, human-in-the-loop process, requiring heavy engineering and often resulting in suboptimal results. In this talk we explore two main directions toward scalable reinforcement learning and autonomy. First, we discuss several methods for zero-shot sim2real transfer for mobile and aerial navigation, including visual navigation and fully autonomous navigation on a severely resource constrained nano UAV. Second, we observe that the interaction between the human engineer and the agent under training as a decision-making process that the human agent performs, and consequently automate the training by learning a decision making policy. With that insight, we focus on zero-shot generalization and discuss a compositional task curriculum that generalizes to unseen tasks of evolving complexity. We show that across different applications, learning methods improve reinforcement learning agents generalization and performance, and raise questions about nurture vs nature in training autonomous systems.

Title: “Dealing with the objective function with multiple extrema in robot learning”
In the real world, there are often diverse solutions to a problem. For example, when walking at a certain speed, there can be infinitely many walking styles to achieve the specified speed. The existence of multiple solutions is often originated from the multiple extrema in an objective function in robot learning. While discovering a single solution may be sufficient to solve the problem at hand, extracting diverse behaviors from a single task could be an efficient way to obtain skill repertoires for downstream tasks. In this talk, we will discuss methods for discovering diverse solutions in the context of motion planning and reinforcement learning. We will first discuss the problem formulation for discovering diverse solutions in motion planning and how to solve it. Next, we will discuss reinforcement learning methods for discovering diverse policies. This talk aims to provide basics of discovering diverse solutions in robot learning and share our experience through case studies.

Title: “Simulation-Based Probabilistic Inference for Domain Randomization and Sim2Real Transfer”
Recent advancements in simulation technology enable the fast development of decision-making algorithms that can be tested and tuned in simulation before they are deployed to the real world. However, what happens when the simulator does not represent reality well? Can they still be useful? In this presentation I address this question from a probabilistic inference perspective and describe a number of techniques that allow us to “invert” simulators and compute distributions over simulator parameters given real data. We start with classical simulation-based inference methods where the simulation process is assumed expensive, to efficient and scalable particle-based inference methods suitable for parallel and differentiable simulators. Finally, I present Bayesian domain randomization as a powerful tool to learn policies in simulation that are robust to real world deployments in problems involving autonomous navigation in different terrains, manipulation of granular materials and deformable objects.
