English(EN) Mixed Precision Training of Neural ODEs

神经网络常微分方程通过混合精度训练和因果预测方法取得进展

研究人员开发了一种新的神经网络常微分方程(Neural ODEs)混合精度训练框架,以降低计算成本。该框架使用低精度计算来评估网络输出和存储中间状态,同时通过自定义缩放和高精度累积解和梯度来维持数值稳定性。该方法配有一个名为“rampde”的开源PyTorch包,在图像分类和生成建模等任务中实现了约50%的内存减少和高达2倍的速度提升,准确性与单精度训练相当。 AI

影响 引入了一种显著减少内存和加速Neural ODEs训练的方法,有可能实现更大、更复杂的连续时间模型。

    Observable Neural ODEs for Identifiable Causal Forecasting in Continuous Time

    Causal inference in continuous-time sequential decision problems is challenged by hidden confounders. We show that, in latent state-space models with time-varying interventions, observability of the latent dynamics from observed data is necessary for identifying dynamic treatment…
