Hideaki Iiduka

摘要:

本文研究了深度学习中的非凸随机最优化问题,并提供了适当的学习率,自适应学习率优化算法(如Adam和AMSGrad)可以近似问题的稳定点。特别地,提供恒定和递减的学习速率来近似问题的静止点。我们的结果也保证了自适应学习率优化算法可以逼近凸随机最优化问题的全局极小值。在文本和图像分类的数值实验中,自适应学习率优化算法进行了检查。实验结果表明,学习率恒定的算法比学习率递减的算法性能更好。

英文摘要:

This paper deals with nonconvex stochastic optimization problems in deep learning and provides appropriate learning rates with which adaptive learning rate optimization algorithms, such as Adam and AMSGrad, can approximate a stationary point of the problem. In particular, constant and diminishing learning rates are provided to approximate a stationary point of the problem. Our results also guarantee that the adaptive learning rate optimization algorithms can approximate global minimizers of convex stochastic optimization problems. The adaptive learning rate optimization algorithms are examined in numerical experiments on text and image classification. The experiments show that the algorithms with constant learning rates perform better than ones with diminishing learning rates.
