SELFI: Autonomous Self-Improvement with Reinforcement Learning for Social Navigation

no code implementations1 Mar 2024 Noriaki Hirose, Dhruv Shah, Kyle Stachowicz, Ajay Sridhar, Sergey Levine

Specifically, SELFI stabilizes the online learning process by incorporating the same model-based learning objective from offline pre-training into the Q-values learned with online model-free reinforcement learning.

SACSoN: Scalable Autonomous Control for Social Navigation

no code implementations2 Jun 2023 Noriaki Hirose, Dhruv Shah, Ajay Sridhar, Sergey Levine

By minimizing this counterfactual perturbation, we can induce robots to behave in ways that do not alter the natural behavior of humans in the shared space.

GNM: A General Navigation Model to Drive Any Robot

1 code implementation7 Oct 2022 Dhruv Shah, Ajay Sridhar, Arjun Bhorkar, Noriaki Hirose, Sergey Levine

Learning provides a powerful tool for vision-based navigation, but the capabilities of learning-based policies are constrained by limited training data.

Unsupervised Simultaneous Learning for Camera Re-Localization and Depth Estimation from Video

no code implementations24 Mar 2022 Shun Taguchi, Noriaki Hirose

Monocular camera re-localization refers to the task of estimating the absolute camera pose from an instance image in a known environment, which has been intensively studied for alternative localization in GPS-denied environments.

Depth360: Self-supervised Learning for Monocular Depth Estimation using Learnable Camera Distortion Model

no code implementations20 Oct 2021 Noriaki Hirose, Kosuke Tahara

This framework is attractive for researchers because the depth and pose networks can be trained from just time sequence images without the need for the ground truth depth and poses.
