Learning to Walk with Dual Agents for Knowledge Graph Reasoning

AAAI 2022technical

Graph walking based on reinforcement learning (RL) has shown great success in navigating an agent to automatically complete various reasoning tasks over an incomplete knowledge graph (KG) by exploring multi-hop relational paths. However, existing multi-hop reasoning approaches only work well on shor…
