我们引入了一个有效的预处理算法,以减少过滤后的细胞复合体中的细胞数量,同时保持其持久的同源群。该技术基于组合莫尔斯理论从复合体到过滤的扩展。
We introduce an efficient preprocessing algorithm to reduce the number of cells in a filtered cell complex while preserving its persistent homology groups. The technique is based on an extension of combinatorial Morse theory from complexes to filtrations.
