报告摘要1-norm support vector machine (SVM) generally has competitive performance compared to standard 2-norm support vector machine in classification problems, with the advantage of automatically selecting relevant features. We propose a divide-and -conquer approach in the large sample size and high-dimensional setting by splitting the data set across multiple machines, then averaging the debiased estimators. We show that under appropriate conditions the aggregated estimator can obtain the same convergence rate as the central estimator utilizing all observations.
