Various papers have proposed Deep Reinforcement Learning for autonomous driving.In self-driving cars, there are various aspects to consider, such as speed limits at various places, drivable zones, avoiding collisions — just to mention a few. Hierarchical reinforcement learning (HRL) is a computational approach intended to address these issues by learning to operate on different levels of temporal abstraction .. To really understand the need for a hierarchical structure in the learning algorithm and in … This is just an implementation of the classic “agent-environment loop”. ... OpenAI Baselines: ACKTR & A2C. Hierarchical Reinforcement Learning. The main idea is that after an update, the new policy should be not too far from the old policy. 123 ~50. OpenAI is an AI research and deployment company. View research. Instead of training an RL agent on 1 environment per step, it allows us to train it on n environments per step. 6134 ~6000.

Emergent Tool Use from Multi-Agent Interaction. ... Emergent Tool Use from Multi-Agent Interaction. Through multi-agent competition, the simple objective of hide-and-seek, and standard reinforcement learning algorithms at scale, we find that agents create a self-supervised autocurriculum inducing multiple distinct rounds of emergent strategy, many of which require sophisticated tool use and coordination. Tip FinRL library includes fine-tuned standard DRL algorithms, such as DQN, DDPG, Multi-Agent DDPG, PPO, SAC, A2C and TD3. 一、引言 本章介绍OpenAI 2017发表在NIPS 上的一篇文章，《Multi-Agent Actor-Critic for Mixed Cooperative-Competitive Environments》。 主要是将AC 算法 进行了一系列改进，使其能够适用于传统RL 算法 无法处理的复杂多 智能 体 场景。 Imagine you’re in an airport, searching for your departure gate.
