Manifold Feature Index: A novel index based on high-dimensional data simplification

no code implementations19 Jun 2020 Chenkai Xu, Hongwei Lin, Xuansu Fang

In this paper, we propose a novel stock index model, namely the manifold feature(MF) index, to reflect the overall price activity of the entire stock market.

High-Dimensional Data Set Simplification by Laplace-Beltrami Operator

no code implementations23 Mar 2020 Chenkai Xu, Hongwei Lin

Moreover, we develop feature point detection methods for the functions defined on an unorganized data point set in high-dimensional space, and devise metrics for measuring the fidelity of the simplified data set to the original set.
