报告摘要： In this talk, we propose a novel adaptive distributed learning system based on divide-and-conquer and local average regression for prediction and privacy preservation simultaneously. Different from the classical distributed learning strategy whose algorithmic parameters and patterns are given by the central agent, our approach provides autonomy to each local agent in terms of parameter selection, algorithm designation and data perturbation. Such an adaptive manner significantly enhances the privacy preservation of the system. Our theoretical results demonstrate that the novel adaptive distributed learning system does not degrade the prediction performance of classical systems via presenting optimal learning rates in the framework of statistical learning theory. Our theoretical assertions are verified via numerous numerical experiments including both toy simulations and real data study.     In our analysis, the new system also admits a certain perturbation of the test data via showing an almost comparable accuracy to that of the original data, which provides a realistic possibility for protecting privacy from both training and testing sides.
