我们使用计算化学中的微移弹性带方法来分析高维数据。我们的方法受到莫尔斯理论的启发,作为输出,我们产生了越来越多的小细胞复合体序列,对数据的密集区域进行建模。我们在社交网络和图像处理中产生的数据集上测试该方法。此外,我们应用该方法来识别光流补丁数据集中的新拓扑结构。
We use the nudged elastic band method from computational chemistry to analyze high-dimensional data. Our approach is inspired by Morse theory, and as output we produce an increasing sequence of small cell complexes modeling the dense regions of the data. We test the method on data sets arising in social networks and in image processing. Furthermore, we apply the method to identify new topological structure in a data set of optical flow patches.
