在我们此前的工作中,我们提出了用于神经ODE(神经常微分方程)序列训练的Tuning without Forgetting(TwF,调优不遗忘)原则:训练样本被迭代添加,参数在控制函数子空间内更新,该子空间在一阶近似意义下,保持输出标签流形上已学习样本的端点映射不变。在这篇快报中,我们证明了在非奇异控制下,该参数子空间构成一个有限余维的Banach子流形,并刻画了其切空间。这一结果表明,TwF对应于控制函数沿该Banach子流形切空间的延拓/形变,为其在序列训练中精确(而非仅一阶近似)保持映射不变(即不遗忘)提供了理论基础。
英文摘要:
In our earlier work, we introduced the principle of Tuning without Forgetting (TwF) for sequential training of neural ODEs, where training samples are added iteratively and parameters are updated within the subspace of control functions that preserves the end-point mapping at previously learned samples on the manifold of output labels in the first-order approximation sense. In this letter, we prove that this parameter subspace forms a Banach submanifold of finite codimension under nonsingular controls, and we characterize its tangent space. This reveals that TwF corresponds to a continuation/deformation of the control function along the tangent space of this Banach submanifold, providing a theoretical foundation for its mapping-preserving (not forgetting) during the sequential training exactly, beyond first-order approximation.
