Multiscale Entropy-Based Surface Complexity Analysis for Land Cover Image Semantic Segmentation
Remote Sensing, 2023 Recognizing and classifying natural or artificial geo-objects under complex geo-scenes using remotely sensed data remains a significant challenge due to the heterogeneity in their spatial distribution and sampling bias.

Sample Bias in Caregiving Research [PDF]
Journal of Gerontology, 1990 Data on subject selection biases in research with older adults are limited. We conducted two sample bias studies that assessed primary caregivers for dementia patients. The first study compared 46 caregivers, who required home interviews, with 63 caregivers willing to travel to the university hospital for assessment; all subjects had been offered free ...

Fourier Analysis of Stochastic Sampling Strategies for Assessing Bias and Variance in Integration [PDF]
, 2013 Each pixel in a photorealistic, computer generated picture is calculated by approximately integrating all the light arriving at the pixel, from the virtual scene. A common strategy to calculate these high-dimensional integrals is to average the estimates

Optimizing noninvasive sampling of a zoonotic bat virus
Ecology and Evolution, 2021 Outbreaks of infectious viruses resulting from spillover events from bats have brought much attention to bat‐borne zoonoses, which has motivated increased ecological and epidemiological studies on bat populations.

Sparse sampling, galaxy bias, and voids [PDF]
, 2014 To study the impact of sparsity and galaxy bias on void statistics, we use a single large-volume, high-resolution N-body simulation to compare voids in multiple levels of subsampled dark matter, halo populations, and mock galaxies from a Halo Occupation ...
