新理论推动了尺度不变神经网络优化

研究人员在优化神经网络方面取得了新的理论见解,特别是在尺度不变方法和重尾噪声方面。他们为尺度不变的二阶方法建立了一个依赖于维度的下界,表明某些条件需要大量的预言机调用。为了解决这个问题,他们提出了一种批处理的Scion方法和一种传输的Scion方法,取得了改进的上界,并在各种神经网络架构中展示了实际效果。 AI

影响 为更高效、更鲁棒的神经网络训练提供了理论基础,可能影响模型开发。

    尺度不变神经网络优化:范数几何与重尾噪声

    A growing lesson from neural network optimization is that optimizer design should respect how the model is parametrized. Scale-invariant methods become important because their normalized layerwise updates can not only support hyperparameter transfer across model sizes but exploit…
