DOI: 10.1016/j.actaastro.2018.02.033
Abstract: Abstract Pinpoint landing is challenging for future Mars and asteroid exploration missions. Vision-based navigation scheme based on feature detection and matching is practical and can achieve the required precision. However, existing algorithms are computationally prohibitive… read more here.

DOI: 10.1101/2022.04.22.489150
Abstract: Controlling behavior implies a constant balance between exploration – to gather information – and exploitation – to use this information to reach one’s goal. However, how this tradeoff is achieved in navigating animals is unclear.… read more here.

DOI: 10.1109/lra.2020.3048668
Abstract: To enhance the cross-target and cross-scene generalization of target-driven visual navigation based on deep reinforcement learning (RL), we introduce an information-theoretic regularization term into the RL objective. The regularization maximizes the mutual information between navigation… read more here.
