Elaborating on previous works on single-task networks engaged in decision problems, here we consider the multi-task version in the challenging scenario where the state of nature may change arbitrarily. We propose a data diffusion scheme for tracking these changes in real time, and investigate by numerical simulations the corresponding steady-state decision performance. For the slow-adaptation regime, the complete analytical characterization of the agents' status is provided, under the simplifying assumption that the network connection matrix is correctly estimated.AcousticsEngineering, Electrical & ElectronicEngineeringadaptive networksdiffusion schemesmulti-task decisionsslow-adaptation regimeparameter estimationconsensusalgorithmsAdaptation And Learning In Multi-Task Decision Systemstext::conference output::conference proceedings::conference paper
