Comparative accuracies of artificial neural networks and discriminant analysis in predicting forest cover types from cartographic variables
Jock A. Blackard,Denis J. Dean +1 more
TL;DR: The results of the comparison indicated that a feedforward artificial neural network model more accurately predicted forest cover type than did a traditional statistical model based on Gaussian discriminant analysis.
Journal ArticleDOI
Identifying gaps in conservation networks: of indicators and uncertainty in geographic-based analyses
TL;DR: A set of critical assumptions and issues that influence the interpretation and implementation of gap analysis are reviewed, including the assumption that a subset of taxa can be used to indicate overall diversity patterns, and the impact of uncertainty and error propagation in reserve design.
