Mitigating Imbalance of Land Cover Change Data for Deep Learning Models with Temporal and Spatiotemporal Sample Weighting Schemes

open access: yesISPRS International Journal of Geo-Information, 2022
An open problem impeding the use of deep learning (DL) models for forecasting land cover (LC) changes is their bias toward persistent cells. By providing sample weights for model training, LC changes can be allocated greater influence in adjustments to ...

Spatiotemporal Interpolation for Environmental Modelling

open access: yesSensors, 2016
A variation of the reduction-based approach to spatiotemporal interpolation (STI), in which time is treated independently from the spatial dimensions, is proposed in this paper. We reviewed and compared three widely-used spatial interpolation techniques:

Redshift Weights for Baryon Acoustic Oscillations : Application to Mock Galaxy Catalogs [PDF]

open access: yes, 2016
Large redshift surveys capable of measuring the Baryon Acoustic Oscillation (BAO) signal have proven to be an effective way of measuring the distance-redshift relation in cosmology. Building off the work in Zhu et al.

Distances in Weighted Trees and Group Inverse of Laplacian Matrices [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 1997
Formulas are given for group inverses of Laplacians of weighted trees. A relationship between entries of the group inverse and various distance functions on trees is highlighted. In particular, it is shown that the maximal and minimal entries on the diagonal of the group inverse correspond to certain pendant vertices of the tree and to a centroid of ...
