Cooperative and Competitive Biases for Multi-Agent Reinforcement Learning

no code implementations18 Jan 2021 Heechang Ryu, Hayong Shin, Jinkyoo Park

We propose an algorithm that boosts MARL training using the biased action information of other agents based on a friend-or-foe concept.

PGPS : Coupling Policy Gradient with Population-based Search

no code implementations1 Jan 2021 Namyong Kim, Hyunsuk Baek, Hayong Shin

Gradient-based policy search algorithms (such as PPO, SAC or TD3) in deep reinforcement learning (DRL) have shown successful results on a range of challenging control tasks.

REMAX: Relational Representation for Multi-Agent Exploration

no code implementations12 Aug 2020 Heechang Ryu, Hayong Shin, Jinkyoo Park

To train the MARL model effectively without designing the intrinsic reward, we propose a learning-based exploration strategy to generate the initial states of a game.

Does Adam optimizer keep close to the optimal point?

no code implementations1 Nov 2019 Kiwook Bae, Heechang Ryu, Hayong Shin

The adaptive optimizer for training neural networks has continually evolved to overcome the limitations of the previously proposed adaptive methods.

Multi-Agent Actor-Critic with Hierarchical Graph Attention Network

no code implementations27 Sep 2019 Heechang Ryu, Hayong Shin, Jinkyoo Park

Most previous studies on multi-agent reinforcement learning focus on deriving decentralized and cooperative policies to maximize a common reward and rarely consider the transferability of trained policies to new tasks.

Multi-Agent Actor-Critic with Generative Cooperative Policy Network

no code implementations22 Oct 2018 Heechang Ryu, Hayong Shin, Jinkyoo Park

We propose an efficient multi-agent reinforcement learning approach to derive equilibrium strategies for multi-agents who are participating in a Markov game.
