新方法降低了训练循环神经网络的计算成本

研究人员开发了一种称为截断反向传播随时间推移的方法,以降低训练循环神经网络的计算成本。该技术涉及将梯度计算限制在较短的时间范围内,从而产生两种边界效应:缺失的过去信息会影响前向状态,而截断的反向递归会省略未来信息。该研究提出将参数更新的梯度平均与计算上下文分离,从而产生一种双向梯度高速公路性质,其中误差随与上下文边界的距离呈指数衰减。这项工作为梯度对齐和最优性差距提供了理论保证,并在 Wiener-Hammerstein 基准测试上的实验证明了性能与计算成本之间的权衡。 AI

影响 这项研究提供了一种计算效率更高的训练循环神经网络的方法,有可能支持更大的模型或更快的迭代周期。

    Truncated backpropagation through time reduces the computational burden of training recurrent models by restricting gradient computations to shorter temporal contexts. This induces two distinct boundary effects: missing past information perturbs the forward state evolution, while…
