- Abstract:
-
To solve the problems of reinforcement learning in the visual semantic navigation task, such as low accuracy, low navigation efficiency, poor fault tolerance rate, and the suitability of only some problems for a single agent, we propose a multi-agent target search algorithm based on scene prior. This algorithm extends the single-agent system to a multi-agent system through reinforcement learning. It mainly includes two aspects: first, a scene atlas is used as prior knowledge to assist the agent team in visual exploration; second, the multi-agent reinforcement learning method of centralized training and distributed exploration is used to greatly improve the accuracy and work efficiency of the agent team. Training tests in AI2THOR and comparison with other algorithms prove that this method is superior to other algorithms in target search accuracy and efficiency.
