稀疏二次最优化问题的非加速有效数值方法及其推广

Non accelerated efficient numerical methods for sparse quadratic optimization problems and its generalizations

Anton Anikin, Alexander Gasnikov, Alexander Gornov

摘要:

研究了具有l1-范数的原始梯度法和条件梯度法(两种方法都是非加速的)。我们表明,这些方法可以优于众所周知的加速方法的某些类稀疏二次问题。此外,我们还讨论了一些推广。

英文摘要:

We investigate primal gradient method with l1-norm and conditional gradient method (both methods are non accelerated). We show that these methods can outperform well known accelerated approaches for some classes of sparse quadratic problems. Moreover we discuss some generalizations.
