Diffusion logistic regression algorithms over multiagent networks

In this paper, a distributed scheme is proposed for ensemble learning method of bagging, which aims to address the classification problems for large dataset by developing a group of cooperative logistic regression learners in a connected network. Moveover, each weak learner/agent can share the local weight vector with its immediate neighbors through diffusion strategy in a fully distributed manner. Our diffusion logistic regression algorithms can effectively avoid overfitting and obtain high classification accuracy compared to the non-cooperation mode. Furthermore, simulations with a real dataset are given to demonstrate the effectiveness of the proposed methods in comparison with the centralized one.
