Exploring the Structure of Spatial Representations

PLOS ONE, 2016
It has been suggested that the map-like representations that support human spatial memory are fragmented into sub-maps with local reference frames, rather than being unitary and global. However, the principles underlying the structure of these 'cognitive maps' are not well understood.

THE CORRELATION STRUCTURE OF SPATIAL AUTOREGRESSIONS [PDF]

Econometric Theory, 2012
This paper investigates how the correlations implied by a first-order simultaneous autoregressive (SAR(1)) process are affected by the weights matrix and the autocorrelation parameter. A graph theoretic representation of the covariances in terms of walks connecting the spatial units helps to clarify a number of correlation properties of the processes ...

A Multi-Feature Framework for Quantifying Information Content of Optical Remote Sensing Imagery

Remote Sensing, 2022
Quantifying the information content of remote sensing images is considered to be a fundamental task in quantitative remote sensing. Traditionally, the grayscale entropy designed by Shannon’s information theory cannot capture the spatial structure of ...
