In this paper, we introduce a framework for imitation learning in navigation that enables policy learning from one-shot images without a physical robot and facilitates the transfer of this policy from simulation to reality. Utilizing Neural Radiance Fields (NeRF), our approach generates a simulated…
We consider the problem of learning an optimal expert behavior policy given noisy demonstrations that contain observations from both optimal and non-optimal expert behaviors. Popular imitation learning algorithms, such as generative adversarial imitation learning, assume that (clear) demonstrations…
Planning for visual navigation using topological memory, a memory graph consisting of nodes and edges, has been recently well-studied. The nodes correspond to past observations of a robot, and the edges represent the reachability predicted by a neural network (NN). Most prior methods, however, often…
The goal of imitation learning (IL) is to enable a learner to imitate expert behavior given expert demonstrations. Recently, generative adversarial imitation learning (GAIL) has shown significant progress on IL for complex continuous tasks. However, GAIL and its extensions require a large number of…
