Decentralized Clustering and Linking by Networked Agents

Sahar Khawatmi, Ali H. Sayed, Abdelhak M. Zoubir

摘要:

我们考虑多任务网络上的分散聚类和估计问题,其中代理推断和跟踪不同的模型。代理事先不知道哪个模型正在生成自己的数据。他们也不知道他们邻居中的哪些代理属于同一个集群。我们提出了一个分散的聚类算法,旨在识别和形成集群的代理相似的目标,并在指导合作,以提高推理性能。所提出的技术的一个关键特征是将学习和聚类任务集成到一个单一的策略中。我们分析的过程中的性能,并表明,I型和II型的错误概率呈指数衰减到零的步长参数。虽然在聚类过程中忽略了不同目标的代理之间的联系,但我们仍然展示了如何利用这些联系在整个网络中传递关键信息,以提高性能。仿真结果表明,与其他有用的技术相比,所提出的方法的性能。

英文摘要:

We consider the problem of decentralized clustering and estimation over multi-task networks, where agents infer and track different models of interest. The agents do not know beforehand which model is generating their own data. They also do not know which agents in their neighborhood belong to the same cluster. We propose a decentralized clustering algorithm aimed at identifying and forming clusters of agents of similar objectives, and at guiding cooperation to enhance the inference performance. One key feature of the proposed technique is the integration of the learning and clustering tasks into a single strategy. We analyze the performance of the procedure and show that the error probabilities of types I and II decay exponentially to zero with the step-size parameter. While links between agents following different objectives are ignored in the clustering process, we nevertheless show how to exploit these links to relay critical information across the network for enhanced performance. Simulation results illustrate the performance of the proposed method in comparison to other useful techniques.
