Proceedings ArticleDOI
Support vector learning for ordinal regression
TL;DR: Experimental results indicate that the presented algorithm outperforms more naive approaches to ordinal regression such as support vector classification and support vector regression in the case of more than two ranks.
Journal ArticleDOI
Self-organizing maps: ordering, convergence properties and energy functions
TL;DR: In this paper, the authors investigated the convergence properties of the self-organizing feature map algorithm for a simple, but very instructive case: the formation of a topographic representation of the unit interval [0, 1] by a linear chain of neurons.
Journal ArticleDOI
Geometry of orientation and ocular dominance columns in monkey striate cortex
Klaus Obermayer,GG Blasdel +1 more
TL;DR: It is shown that ocular dominance is organized in slabs and that orientation preferences are organized in linear sequences likely to reflect slabs, and that linear zones (arising where orientation preferences change along straight axes) tend to lie at the edges of Ocular dominance columns.
Journal ArticleDOI
Invariant computations in local cortical networks with balanced excitation and inhibition
Jorge Mariño,James Schummers,David C. Lyon,David C. Lyon,Lars Schwabe,Oliver Beck,Peter Wiesing,Klaus Obermayer,Mriganka Sur +8 more
TL;DR: A mechanism by which orientation selectivity is computed invariantly in cat primary visual cortex across an orientation preference map that provides a wide diversity of local circuits is demonstrated.
Journal ArticleDOI
Models of Orientation and Ocular Dominance Columns in the Visual Cortex: A Critical Comparison
TL;DR: Ten of the most prominent models of cortical map formation and structure are critically evaluated and compared with the most recent experimental findings from macaque striate cortex and several models produce orientation map patterns that are not consistent with the experimental data from macaques.
