No RL, No Simulation: Learning to Navigate without Navigating

open access: yesCoRR, 2021
Most prior methods for learning navigation policies require access to simulation environments, as they need online policy interaction and rely on ground-truth maps for rewards. However, building simulators is expensive (requires manual effort for each and every scene) and creates challenges in transferring learned policies to robotic platforms in the ...

Benchmarking Projective Simulation in Navigation Problems

open access: yesIEEE Access, 2018
Projective simulation (PS) is a model for intelligent agents with a deliberation capacity that is based on episodic memory. The model has been shown to provide a flexible framework for constructing reinforcement-learning agents, and it allows for quantum mechanical generalization, which leads to a speed-up in deliberation time.

The Virtual Model of Deep Water Container Terminal T2 in Port Gdańsk [PDF]

open access: yesTransNav, 2018
The level of education of seafarers currently depends among other things on the use of simulators in the training process. The reliability of the computer simulation depends on several factors such as own ship models or virtual training areas.

Automatic collision avoidance of ships [PDF]

open access: yes, 2008
One of the key elements in automatic simulation of ship manoeuvring in confined waterways is route finding and collision avoidance. This paper presents a new practical method of automatic trajectory planning and collision avoidance based on an artificial
