降维即流量分配:点集扁平化的工程实质

在多原点曲率(MOC)框架下,从三维到二维的连续过渡,本质上是点集的渐进扁平化过程,也是一场典型的流量再分配过程。

这一过程并非简单剔除节点或减少分支;相反,为使结构适配平面形态,网点数量甚至可能增加。其实质在于:高维纵深方向的流量被逐步约束与收敛,流向各支脉的分量随之减少,整体结构在保留拓扑连通性的前提下,实现维度的可控塌缩。

从信息论视角看,降维体现为信息量的有序缩减——不是信息的粗暴丢失,而是通过流量重定向,将原本弥散于三维空间的分布约束到二维平面。在降低系统冗余与复杂度的同时,主干结构与关键特征得以完整保留。

这便是降维的工程实质:流量重分配,而非节点删除;信息收敛,而非信息湮灭。
