no code implementations28 May 2024 Zhangyu Wang, Krzysztof Janowicz, Gengchen Mai, Ivan Majic

Intuitively, there is a relation between measures of spatial dependence and information theoretical measures of entropy.

MC-GTA: Metric-Constrained Model-Based Clustering using Goodness-of-fit Tests with Autocorrelations

1 code implementation28 May 2024 Zhangyu Wang, Gengchen Mai, Krzysztof Janowicz, Ni Lao

A wide range of (multivariate) temporal (1D) and spatial (2D) data analysis tasks, such as grouping vehicle sensor trajectories, can be formulated as clustering with given metric constraints.

A Ground Segmentation Method Based on Point Cloud Map for Unstructured Roads

no code implementations15 Sep 2023 Zixuan Li, Haiying Lin, Zhangyu Wang, Huazhi Li, Miao Yu, Jie Wang

Unstructured road scenes represented by open-pit mines have irregular boundary lines and uneven road surfaces, which lead to segmentation errors in current ground segmentation methods.
