On the Similarity of Eagles, Hawks, and Cows: Visualization of Semantic Similarity in Self-Organizing Maps
We describe an extension to the self-organizing map learning rule enabeling a straightforward visual representation of input data similarity in high-dimensional input structures. The general idea of the extension is to mirror the movement of weight vectors during the training process within a two-dimensional (virtual) output space. The result of the extended training algorithm allows intuitive ...

متن کاملPopulations and Prey Selection of Wintering Raptors in Boulder County, Colorado
Wintering raptor populations were monitored between 1983 and 1988 in a 35 km2 study area centered 8 km north-northeast of the city of Boulder, Colorado. Raptors congregated around active prairie dog (Cynomys sp.) colonies. Golden eagles (Aquila chrysaetos) , ferruginous hawks (Buteo regalis), and red-tailed hawks (Buteo jamaicensis ) were observed hunting and capturing prairie dogs. Bald eagles...
متن کاملNotes on Breeding Sharp-shinned Hawks and Cooper’s Hawks in Barnwell County, South Carolina
Breeding records of Accipiter striatus (Sharp-shinned Hawks) in the southeastern US are scattered and isolated. We documented a Sharp-shinned Hawk and Accipiter cooperii (Cooper’s Hawk) nest while conducting a telemetry study on Melanerpes erythrocephalus (Red-headed Woodpeckers) in Barnwell County, SC in 2006 and 2007. We report the fi rst known nest of a Sharp-shinned Hawk in Barnwell County,...
متن کاملHawks, Doves and Lifetime Reproductive Fitness
Evolutionary game theory is an adaptation of classical game theory used to analyse and explain observed natural phenomena where organisms choose between alternative behavioural strategies. Recent analyses and simulations of evolutionary games have shown that implementation choices such as population size and selection method can have unexpected effects on the course of evolution. In this paper,...
