Deep Learning Stage [clear filter]

Deep Robotic Learning
Deep learning has been demonstrated to achieve excellent results in a range of passive perception tasks, from recognizing objects in images to recognizing human speech. However, extending the success of deep learning into domains that involve active decision making has proven challenging, because the physical world presents an entire new dimension of complexity to the machine learning problem. Machines that act intelligently in open-world environments must reason about temporal relationships, cause and effect, and the consequences of their actions, and must adapt quickly, follow human instruction, and remain safe and robust. Although the basic mathematical building blocks for such systems -- reinforcement learning and optimal control -- have been studied for decades, such techniques have been difficult to extend to real-world control settings. For example, although reinforcement learning methods have been demonstrated extensively in settings such as games, their applicability to real-world environments requires new and fundamental innovations: not only does the sample complexity of such methods need to be reduced by orders of magnitude, but we must also study generalization, stability, and robustness. In this talk, I will discuss how deep learning and reinforcement learning methods can be extended to enable real-world robotic control, with an emphasis on techniques that generalize to situations, objects, and tasks. I will discuss how model-based reinforcement learning can enable sample-efficient control, how model-free reinforcement learning can be made efficient, robust, and reliable, and how meta-learning can enable robotic systems to adapt quickly to new tasks and new situations.

Meta-Learning Deep Networks
Deep learning has enabled significant advances in a variety of domains; however, it relies heavily on large labeled datasets. I will discuss how we can use meta-learning, or learning to learn, to enable us to adapt deep models to new tasks with tiny amounts of data, by leveraging data from other tasks. By using these meta-learning techniques, I will show how we can build better unsupervised learning algorithms, build agents that can adapt online to changing environments, and build robots that can interact with a new object by watching a single demonstration.

Latent Structure in Deep Robotic Learning
Traditionally, deep reinforcement learning has focused on learning one particular skill in isolation and from scratch. This often leads to repeated efforts of learning the right representation for each skill individually, while it is likely that such representation could be shared between different skills. In contrast, there is some evidence that humans reuse previously learned skills efficiently to learn new ones, e.g. by sequencing or interpolating between them.
In this talk, I will demonstrate how one could discover latent structure when learning multiple skills concurrently. In particular, I will present a first step towards learning robot skill embeddings that enable reusing previously acquired skills. I will show how one can use these ideas for multi-task reinforcement learning, sim-to-real transfer and imitation learning.
