On cross-validation and stacking: building seemingly predictive models on random data
A number of times when using cross-validation (CV) while trying to do classification/probability estimation we have observed surprisingly low AUC's on real data with very few...

Rational Spherical Splines for Genus Zero Shape Modeling
Traditional approaches for modeling a closed manifold surface with either regular tensor-product or triangular splines (defined over an open planar domain) require decomposing th...

Rapid scene modelling, registration and specification for mixed reality systems
Many mixed-reality systems require real-time composition of virtual objects with real video. Such composition requires some description of the virtual and real scene geometries an...

Alpha-Frequency Rhythms Desynchronize over Long Cortical Distances: A Modeling Study
Neocortical networks of excitatory and inhibitory neurons can display alpha()-frequency rhythms when an animal is in a resting or unfocused state. Unlike some - and -frequency rhy...
