DistGP通过分布式高斯过程实现多机器人协同制图,优于现有方法并在动态环境下表现更优。
摘要:
我们提出了DistGP:一种多机器人学习方法,用于通过仅本地经验和计算进行协同学习全局函数。我们利用一种稀疏高斯过程(GP)模型,其分解方式与任务的多机器人结构相匹配,并允许通过高斯信念传播(GBP)进行分布式训练。我们的环形模型优于树状高斯过程(Tree-Structured GPs)\cite{bui2014tree},并且可以在动态连接设置中在线训练。我们证明,这种分布式、异步训练可以达到集中式、批量训练模型的相同性能,尽管收敛速度较慢。最后,我们与DiNNO \cite{yu2022dinno},一种分布式神经网络(NN)优化器进行比较,发现DistGP在准确性上更优,对稀疏通信更鲁棒,并且更能持续学习。
英文摘要:
We propose DistGP: a multi-robot learning method for collaborative learning of a global function using only local experience and computation. We utilise a sparse Gaussian process (GP) model with a factorisation that mirrors the multi-robot structure of the task, and admits distributed training via Gaussian belief propagation (GBP). Our loopy model outperforms Tree-Structured GPs \cite{bui2014tree} and can be trained online and in settings with dynamic connectivity. We show that such distributed, asynchronous training can reach the same performance as a centralised, batch-trained model, albeit with slower convergence. Last, we compare to DiNNO \cite{yu2022dinno}, a distributed neural network (NN) optimiser, and find DistGP achieves superior accuracy, is more robust to sparse communication and is better able to learn continually.
