Abstract(in English) | We consider a constrained optimization problem of minimizing the sum of the local convex objective function values of agents over a strongly connected graph. In the proposed method, we propose a distributed mini-batch stochastic subgradient algorithm that solves the optimization problem in a distributed manner using stochastically sampled data. In this paper, we study the convergence of the proposed algorithm from the viewpoint of the regret analysis based on the row stochasticity of the weight matrix corresponding to the communication network. We show the validity of the proposed method through numerical experiments. |
