TROPHY: A Topologically Robust Physics-Informed Tracking Framework for Tropical Cyclones

no code implementations28 Jul 2023 Lin Yan, Hanqi Guo, Thomas Peterka, Bei Wang, Jiali Wang

In comparison with the observed tracks, we demonstrate that TROPHY can capture TC characteristics that are comparable to and sometimes even better than a well-validated TC tracking algorithm that requires multiple dynamic and thermodynamic scalar fields.

Multilevel Robustness for 2D Vector Field Feature Tracking, Selection, and Comparison

no code implementations19 Sep 2022 Lin Yan, Paul Aaron Ullrich, Luke P. Van Roekel, Bei Wang, Hanqi Guo

However, in practice, the computation of classic robustness may produce artifacts when a critical point is close to the boundary of the domain; thus, we do not have a complete picture of the vector field behavior within its local neighborhood.

Sketching Merge Trees for Scientific Data Visualization

no code implementations8 Jan 2021 Mingzhe Li, Sourabh Palande, Lin Yan, Bei Wang

That is, given a large set T of merge trees, we would like to find a much smaller basis set S such that each tree in T can be approximately reconstructed from a linear combination of merge trees in S. A set of high-dimensional vectors can be sketched via matrix sketching techniques such as principal component analysis and column subset selection.
