The problem of Multi-Agent Reinforcement Learning (MARL) shows a high level of both complexity in the environment and coordination between agents. In order to scale the algorithm to large-scale agent scenarios, neural networks designed for MARL are typically implemented with parameter sharing. These
In the future, unmanned autonomous air combat will encounter large-scale confrontation scenarios, where agents must consider complex time-varying relationships among aircraft when making decisions. Previous works have already introduced Multi-Agent Reinforcement Learning (MARL) into air combat and s…
For binocular stereo, traditional cameras excel in capturing fine details and texture information but are limited in terms of dynamic range and their ability to handle rapid motion. On the contrary, event cameras provide pixel-level intensity changes with low latency and a wide dynamic range, albeit…
In reinforcement learning, the optimism in the face of uncertainty (OFU) is a mainstream principle for directing exploration towards less explored areas, characterized by higher uncertainty. However, in the presence of environmental stochasticity (noise), purely optimistic exploration may lead to ex…
Reviewing the previous work of diversity Reinforcement Learning, diversity is often obtained via an augmented loss function, which requires a balance between reward and diversity. Generally, diversity optimization algorithms use Multi-armed Bandits algorithms to select the coefficient in the pre-def…
The popular Proximal Policy Optimization (PPO) algorithm approximates the solution in a clipped policy space. Does there exist better policies outside of this space? By using a novel surrogate objective that employs the sigmoid function (which provides an interesting way of exploration), we found th…
Multi-agent reinforcement learning has drawn increasing attention in practice, e.g., robotics and automatic driving, as it can explore optimal policies using samples generated by interacting with the environment. However, high reward uncertainty still remains a problem when we want to train a satisf…
Deep reinforcement learning has achieved great success in laser-based collision avoidance work because the laser can sense accurate depth information without too much redundant data, which can maintain the robustness of the algorithm when it is migrated from the simulation environment to the real wo…
We present Coordinated Proximal Policy Optimization (CoPPO), an algorithm that extends the original Proximal Policy Optimization (PPO) to the multi-agent setting. The key idea lies in the coordinated adaptation of step size during the policy update process among multiple agents. We prove the monoton…
