Maxent-directed field surveys identify new populations of narrowly endemic habitat specialists [PDF]
PeerJ, 2017 Background Rare or narrowly endemic organisms are difficult to monitor and conserve when their total distribution and habitat preferences are incompletely known.

Convex foundations for generalized MaxEnt models [PDF]
AIP Conference Proceedings, 2014 We present an approach to maximum entropy models that highlights the convex geometry and duality of generalized exponential families (GEFs) and their connection to Bregman divergences. Using our framework, we are able to resolve a puzzling aspect of the bijection of Banerjee and coauthors between classical exponential families and what they call ...

Bayesian inference of nanoparticle-broadened x-ray line profiles [PDF]
, 2003 A single and self-contained method for determining the crystallite-size distribution and shape from experimental x-ray line profile data is presented. We have shown that the crystallite-size distribution can be determined without assuming a functional ...

Global potential distribution prediction of Xanthium italicum based on Maxent model [PDF]
Scientific Reports, 2021 AbstractAlien invasive plants pose a threat to global biodiversity and the cost of control continues to rise. Early detection and prediction of potential risk areas are essential to minimize ecological and socio-economic costs. In this study, the Maxent model was used to predict current and future climatic conditions to estimate the potential global ...

Geospatial modeling approach to monument construction using Michigan from A.D. 1000–1600 as a case study [PDF]
, 2016 Building monuments was one way that past societies reconfigured their landscapes in response to shifting social and ecological factors. Understanding the connections between those factors and monument construction is critical, especially when multiple ...
