English(EN) When Does Scale-Invariant Optimization Become Unstable? An Exact Schedule Law with Weight Decay

新定律精确预测神经网络优化不稳定性

研究人员发现了一个精确的数学定律,该定律控制着神经网络中 Scale-Invariant Optimization 的不稳定性。该定律揭示了学习率调度与权重衰减之间的反馈循环,该循环由参数范数介导,参数范数决定了优化器的有效步长。该研究提出了一个精确控制训练动态的单一标量量,并确定了区分稳定和不稳定学习率区域的清晰边界。该框架为理解优化器行为和设计训练调度提供了新的视角,其研究结果已在包括 MLP、CNN 和 GPT2 在内的各种神经网络架构和数据集上得到验证。 AI

影响 为优化深度学习训练动态和调度设计提供了一个精确、可操作的框架。
