新理论解释梯度裁剪在稳定AI训练中的作用

研究人员开发了一个理论框架,用以解释为什么梯度裁剪能够稳定深度学习中的异步随机梯度下降(ASGD)。他们的工作表明,裁剪消除了ASGD收敛对慢速工作节点造成的最大延迟的依赖。这一理论依据得到了一个新的梯度噪声子-威布尔模型(sub-Weibull model)的支持,该模型泛化了现有模型,并受到深度学习中经验观察的启发。该研究还首次实现了异步优化算法高概率收敛的演示。 AI

影响 为一种常见的深度学习训练技术提供了理论基础,有望带来更鲁棒、更高效的模型开发。

    剪枝使分布式和联邦异步SGD对掉队者具有鲁棒性

    In modern machine learning, parallelization of training is an important strategy for increasing scale. Asynchronous stochastic gradient descent (ASGD), which maximizes the utilization of available hardware by avoiding waiting for slow workers. However, with constant step sizes, t…
